Automatic Spray Coating Systems: a Complete Guide

Automatic spray coating systems represent a significant advancement for all companies, regardless of the sector, seeking increasingly innovative finishing techniques. As the name suggests, these are systems that use automation and data analysis to apply paints, protective materials, and other coatings with precision and efficiency.

Choosing these solutions correctly is essential for organisations aiming to achieve high-quality finishes and improve operational efficiency. The reasons are numerous: firstly, automatic spray coating systems minimise human error. A traditional approach, based on manual techniques, can lead to inconsistencies and unevenness in coating thickness, structure, and finish quality.

In traditional coating methods, variability can arise from factors such as technique, speed, and environmental conditions. Automated systems, instead, reduce these issues thanks to robotics and advanced control systems that maintain stable parameters throughout the process. Operational stability is essential not only for aesthetics, but also for functional performance. Irregular coatings can actually cause problems such as corrosion, wear, and premature deterioration. Moreover, automation increases production without compromising the output quality.

For this reason, the growing demand for high-quality and long-lasting finishes makes investing in automatic spray coating systems a strategic priority for any manufacturer.

Key technologies and components

The effectiveness of automatic spray coating systems depends on the integration of various technologies and components that work together to optimise all process phases. At the heart of these ecosystems is robotics: precision and repeatability are essential to ensure high-quality results. Robotic arms can be equipped with self-programming features and specific patterns, ensuring that every centimetre of the surface is evenly coated, regardless of shape or size.

Of course, the mechanism could not function without sensors that monitor in real time the essential parameters for proper process operation, such as temperature, humidity, and coating thickness. The sensors allow immediate adjustments during every processing phase.

Control software is also an integral part of the system, including those based on IoT systems and Industry 4.0 principles to collect and analyse data, supporting operators in performance monitoring and process optimisation over time. Thanks to what interconnected machines and systems enable, line managers enjoy greater visibility into operations, improving decision-making and supply chain resilience.

By leveraging these synergies, manufacturing companies can reach previously unthinkable efficiency levels, reducing downtime and cutting operational costs.

Benefits and advantages of automatic spray coating systems

The adoption of automatic spray coating systems brings numerous benefits. The first and most obvious is increased productivity. Automated systems operate continuously, ensuring that output quality is not affected by fatigue or the variability typical of human work. This translates into faster delivery times and greater uniformity in the final product, enabling companies to compete with a reliability that many competitors cannot offer.

Equally important, these systems improve management of the consumables inventory and reduce material waste during processing. By precisely controlling the amount of coating applied, machines minimise overspray and eliminate dripping, common side effects in manual techniques

Uniformity in coating application is essential, especially for products that require specific quality standards, as in certain vertical sectors. Automatic spray coating systems can maintain consistent coating thickness, reducing the risk of defects

Additionally, safety is another important benefit: by reducing the need for manual handling of hazardous materials and exposure to volatile organic compounds, automated systems lead to safer and healthier working environments.

Applications in the main manufacturing sectors

Automatic spray coating systems are being used in an increasing number of industrial sectors, also thanks to digital transformation. Each sector can benefit from these technologies, customising them to meet specific quality and production requirements.

In the aerospace sector, for instance, these systems are essential for applying lightweight and durable coatings, capable of withstanding extreme conditions. Automatically applied coatings ensure each component is treated uniformly, a key factor for aircraft safety and performance.

The automotive industry has also been leveraging the advantages of automated systems for years, achieving high-gloss finishes and protective coatings on vehicles, in compliance with strict safety and durability standards.

In the furniture industry, automatic coating technology enables the rapid application of high-quality finishes on wood or composite surfaces, improving the appearance and lifespan of products while reducing labour costs.

Beyond these more traditional sectors, areas such as electronics and construction are increasingly turning to automated spray coating solutions to improve their finishing processes.

What makes industrial digital printing a good solution for flooring?

Floor decoration and digital printing: a combination that is still seldom used in the finishing sector but has enormous potential. As we know, floors can be challenging surfaces to work with. Industrial digital printing technologies provide manufacturers with valuable support by delivering high-quality, customised products able to withstand foot traffic. This last aspect is particularly relevant, as abrasion resistance is regulated by international standards that define the compliance of each product.

What does digital printing mean for flooring?

Firstly: why install an industrial digital printing machine? Let's start by saying that industrial digital printing is a versatile, innovative floor decoration solution. It allows the application of designs, motifs and images directly on the flooring materials.

The technology doesn’t just guarantee an ultra-high resolution printing process: it also reproduces vivid colours and complex details, allowing businesses and property owners to decorate their surroundings with unique images.

Whether used to create high-impact graphic design in retail areas, personalised patterns in residential interiors or branding elements in corporate offices, digital printing for floors can, in combination with tried and tested finishing technologies and innovative texturing technologies, produce durable, high-quality finishes that withstand foot traffic and long-term wear.

Furthermore, compared to traditional solutions, industrial digital printing is more sustainable as it wastes less material and allows manufacturers to change the design without having to resort to lengthy plant set-up procedures. 

THE MOST INNOVATIVE FINISHING SOLUTIONS
Discover how highly advanced finishing solutions can sharpen your competitiveness.

How digital printing on floors is performed

Where used in floor-making processes, industrial digital printing is part of a rather complex production process. In general, the perfect surface finishing cycle involves six-steps:

  • Sealing (in the case of MDF) or adhesion enhancement (for plastic substrates)
  • White layers
  • Digital printing
  • Wear layer
  • Textured layer
  • Finishing layer.

What are the advantages of digital printing for floors?

Digitally printed floor decoration offers a series of advantages: from large-scale batch customisation to high output rates, from excellent aesthetic quality to the ultra-fast conversion of ideas into finished products, plus the ability to reproduce natural materials with precision. Let’s now explore the topic in more detail.

High levels of customisation

Unlike traditional techniques - which involve cumbersome set-ups and have limited design capabilities - digital printing lets manufacturers create unique, customised designs that respond to customers’ specific needs. This is particularly advantageous in the flooring industry, where consumer preferences are shifting towards ever-wider colour ranges and high-definition patterns and textures that seek to replicate natural materials such as wood or stone.

Sustainability and waste reduction

In general, industrial digital printing helps make production processes more sustainable. Traditional printing methods often waste considerable amounts of ink and material, especially during design changeover, set-up and cleaning tasks. Digital printing, instead, uses only the quantities of ink and materials needed for each job, significantly reducing waste.

Cost efficiency

Compared to traditional methods, industrial digital printing technology may require a higher initial investment outlay but the long-term savings will be substantial. Less waste, minimised set-up times and simplified production processes all help reduce operating costs. What’s more, the ability to perform short production runs lessens the financial risk for manufacturers who want to test new designs or products on the market.

High-quality results

Digital printing technology is synonymous with high resolution and precision. This ensures floor designs are rendered with the utmost clarity and detail. The depth of colour and precision of the intricate patterns enhance overall final product quality, meeting the needs of an increasingly demanding market that wants both high-grade aesthetics and durability.

Simplified workflows and easy integration

Another advantage of digital printing in floor finishing is that it can be integrated into existing workflows with ease. Advanced digital printing systems can be incorporated seamlessly into production processes, minimising downtime and interruptions: a crucial factor for a better-organised production line which, in turn, delivers tip-top efficiency and streamlines communication between the design and production teams.

Improved durability and performance

Industrial digital printing technology delivers tangible advantages not just aesthetically but also in terms of finished product performance. Manufacturers can, in fact, rely on digital inks that are designed to be more durable and more resistant to fading and other environmental factors. This means that floors finished with digitally printed designs maintain their original appearance and integrity over time, offering lasting value to consumers and businesses.

Inherent flexibility and time savings

A key advantage of this technology is its exceptional flexibility in response to changing market trends. Even with small batches - which require frequent set-ups - the ability to adjust the lines quickly saves time and resources, minimising the stock of semi-finished products.

Durability: a key factor

As mentioned, resistance to foot traffic is a crucial factor when selecting a floor finishing solution. The risk of surface deterioration is particularly high in areas such as hotel foyers, corridors, offices, showrooms, schools and retail outlets where there is a constant flow of people.

In these cases, flooring durability is regulated by the EN 15468 and EN 13329 standards that apply to laminate flooring.

Coating products that are used in combination with the industrial digital printing process and are intended for the flooring sector must comply with abrasion resistance class AC5 (hotel halls, corridors, offices). Moreover, more and more coatings employed in combination with industrial digital printing fall, in full, within ‘class of use 33’ for areas with intense foot traffic (large offices, shops).

This is why Cefla Finishing, in designing digital printing solutions for floors, has carried out and passed all the tests required by the regulation, in compliance with AC4 and AC5 (Abrasion Criteria) standards for digitally printed products.

Practical digital printing applications for floors

The floor-making process is largely designed to meet the needs of the market for indoor products, most of which are used in retail and residential construction projects.

Nevertheless, specific applications for outdoor flooring surfaces also exist: for example, decking is ideal for those who need to set up showrooms or trade fair stands, public areas with high levels of pedestrian traffic or shared open-air areas in residential and hotel settings.

Inks for digital printing of floors: organic vs inorganic

Note, however, that the type of ink used in the digital printing process needs to be selected with care as consumables, in fact, determine the long-term aesthetic quality and durability of the flooring.

Organic pigmented inks, for example, tend to fade. Outdoors, colours tend to deteriorate during the first two years of exposure to natural light unless special anti-UV coatings are applied.

Fortunately, inorganic inks with metal oxide pigments - which will remain virtually unaltered by light for more than ten years - can be used.

So, while organic pigmented inks are perfect for indoor use (and certain outdoor areas if adequately protected against UV damage), inorganic pigmented inks are a good choice for outdoor applications, such as decking.

Innovations in digital printing for flooring

Lastly, industrial digital printing improves floor finishing processes by employing highly innovative techniques. Just think of texturing. By producing surfaces with dense relief patterns or tiny marks, texturing completes the sensory experience from both tactile and visual standpoints. This is crucial for success on the décor market, where the goal is to obtain prints that realistically reproduce natural materials.

In short, thanks to digital printing, the only limits are those posed by your imagination.

Optical Treatment for Solar Panels: Which Process is the Best?


In an industrial scenario that is increasingly “going green” by continuing to invest in solutions capable of reducing the carbon footprint of business operations, solar panels are today a key technology. Today's complex and advanced systems designed to guarantee top performance and maximum efficiency deserve the best finishing technologies.

Just think of the role played by the thin layer of anti-reflective coating (commonly shortened to ARC). It is an optical coating applied to solar panels in minimal quantities, such as to be considered nanometric applications. This treatment improves the efficiency of the solar panel as less light is lost through reflection. Just think that with this treatment 3% to 4% more energy is supplied - by capturing the light that would otherwise be lost through reflection. These optical gains can help recover any capacity lost due to normal module degradation. We already mentioned that anti-reflective finishes are nanometric applications: for this reason, the treatment must be applied so as to ensure the highest possible uniformity.

In this feature we will review different types of solar panel, and then focus on advanced optical treatment solutions for solar panels, developed based on Cefla Finishing's expertise.


Innovation and sustainability in solar panels: advanced technologies and energy efficiency

The solar panel market offers a diverse range of technologies suitable for several applications - from residential rooftops to large solar parks. Understanding the characteristics and benefits of the different types of solar panel (monocrystalline, polycrystalline, thin-film and bifacial) is essential in order to make informed investment decisions.

Below is an overview of the current range configuration, showing the intended use and benefits of each product.

THE MOST INNOVATIVE FINISHING SOLUTIONS
Discover how highly advanced finishing solutions can sharpen your competitiveness.

 

Types of solar panel and their applications

Solar panels, the main technology using photovoltaic energy, can feature different structures and materials, each with distinct characteristics suited to many types of application.

Monocrystalline solar panels

Monocrystalline solar panels, for example, have a single continuous crystalline structure, usually silicon. They are easily recognisable as they are uniformly dark in colour with rounded edges, which indicates the high degree of purity of the material used in the production process.

This type of solution ensures the highest efficiency rates, often exceeding 20%. This makes them ideal for situations where roof space is limited. Thanks to their long life (often exceeding 25 years), microcrystalline solar panels are highly suitable for installation in urban environments and particularly on the roofs of residential buildings.

Polycrystalline solar panels

Polycrystalline panels are made up of multiple silicon crystals fused together. Precisely because of this type of processing, which generates multiple crystalline structures, these panels have a characteristically blue spotted appearance.

Generally, these panels are cheaper to produce than monocrystalline panels, but their efficiency rates are also lower and generally range between 15% and 20%: these values, while being not as high as monocrystalline panel ones, are still suitable for many applications.

In fact, thanks to their lower cost, these panels are often used in large-scale solar projects with particularly large surface areas and are highly in demand for covering fields or for remote installations.

Amorphous silicon modules

While also less efficient than monocrystalline panels, amorphous silicon modules are extremely flexible. Solar panels of this type are an excellent solution for creating photovoltaic systems in areas where solar radiation is weaker due to unfavourable climatic conditions - maximising the output from high temperatures or diffused light. From an aesthetic point of view, they stand out for their uniformly dark colour, while in terms of performance they offer versatility and lightness. Thanks to their low production costs and other characteristics, they are ideal for implementing highly verticalised applications, particularly in the architectural field.

Thin film panels

Amorphous silicon is also used to make thin-film panels by coating an underlying surface with a thin layer of photovoltaic material (cadmium telluride and copper indium gallium selenide in addition to silicon). This approach provides flexibility and lightness and makes thin-film panels the ideal solution for covering structures with non-linear shapes. They generally perform better in low-light conditions than the other panels listed above and are therefore used in conjunction with building components such as windows and roofs.

Advanced optical treatment of solar panels in the Cefla Finishing LAB

Regardless of the type of solar panel and application, the use of photovoltaic energy offers companies numerous advantages: energy savings, tax incentives, energy self-sufficiency, increased company value and improved sustainability reputation. To maximise these benefits, however, it is essential to be able to rely on quality products, capable not only of offering excellent performance whenever and in whichever way they are used, but also of maintaining this standard of performance over time. In other words, solar panels need to have a finish that's up to the task.

In our Cefla Finishing LAB, we have developed an ad hoc process, which includes the application of ARC using a very special roller machine called Solarcoater, able to guarantee excellent uniformity in the application of the ARC layer which, as we said before, is measurable in nanometres .

After application, the glass panel is fed through a drying oven to cause the ARC material to completely evaporate before the glass is tempered. It should be noted that there are two types of ARC, and the most common one requires glass tempering to permanently fix the coating. The other less common type only requires fixing of the coating at high temperature in the ovens.

Cefla Finishing and ARC application on solar panels

With its 60 years of experience in creating industrial finishing solutions, Cefla Finishing has developed an innovative range of machines for the application of ARC on solar panels.

Thanks to the industry-specific expertise of a team of specialists able to identify the most suitable technologies to meet any need, we can analyse the product, requirements and business objectives of manufacturers with a view to starting a long-term relationship based on a personalised roadmap.

Production process optimization: Cefla Finishing solutions

Production process optimization plays a pivotal role in improving cost efficiency, reducing waste and boosting product quality. Manufacturers in the finishing sector can - by implementing advanced technologies such as integrated coating lines, robotics and digital printing - streamline workflows, minimise bottlenecks and achieve greater processing precision.

First of all, we need to clarify something: the principles and tools of so-called lean manufacturing will only generate the anticipated benefits if there is a broad, cohesive strategy, of which the technological aspect is just the tip of the iceberg.

To take quality to the next level, it’s simply not enough to purchase the latest-generation machines. In addition to identifying and eliminating low-added-value activities - with a view to shortening time-to-market without losing control of operating costs - it’s necessary to adopt sustainable practices such as recycling waste materials and using eco-friendly finishing agents. Strengthened relationships with suppliers and employees are equally vital. Additionally, investment in training promotes a culture of continuous improvement, allowing the industry to respond flexibly to market demand and truly benefit from innovation.

What is production process optimization?

Any organisation intent on optimizing its production processes needs to prioritise along three lines: eliminating inefficiencies, reducing costs and improving quality
In the finishing industry, the most innovative companies have already drawn up and followed ‘roadmaps’ with three main branches: specialised coating processes, automation and digital printing.

Optimizing spray coating processes, for example, largely involves implementing recirculation and rotation systems on the production lines. At a stroke, this approach diverts skilled labour away from menial tasks and reduces the risk of inefficiencies and bottlenecks. Cost reduction, instead, is achieved by installing machines with fast yet simple colour changeover systems that continue to deliver the same high performance without increasing energy or material consumption.

It’s also possible to deploy systems that introduce roller coating techniques. The latter combine excellent manufacturing flexibility - the result of an extremely wide range of applications and good consistency - with minimal solvent emissions thanks to the use of products that, in 95% of cases, have high dry residues (UV). The outcome? High-efficiency lines that retrieve all unused product, allow fast colour changeovers and employ semi-automatic roller cleaning systems that have the further advantage of containing running costs.

Overhead and floor-mounted lines are perfect for managing production batches that require limited worker intervention. They’re also well suited to small orders, which involve frequent changes to colours and processes. All this stems from simplified programming of the coating machines, which feature tools that constantly monitor coating delivery. This prevents waste and reduces the rejection rate among products leaving the line.

Lastly - again with a view to optimizing production processes - there’s the still little-explored area of industrial digital printing, ideal for customising products or handling extremely limited production runs. 

Applying modern digital printing techniques to object decoration doesn’t just let manufacturers deliver products more quickly: it also reduces the need for stock, minimising warehousing requirements and streamlining supply chains.

THE MOST INNOVATIVE FINISHING SOLUTIONS
Discover how highly advanced finishing solutions can sharpen your competitiveness.

Reducing waste and optimizing resources

Optimizing essentially means making the best of scarce resources (time and skills being paramount), reducing material waste (coatings and consumables) and achieving efficient energy management.

As we see it, digital printing has yet to gain its rightful place as a production process optimizer. Compared to traditional decoration systems, in fact, industrial digital printing can play a crucial role in reducing waste as it does not require:

  • engraved roller changeovers, which waste time and reduce productivity;
  • ink changeovers, which require the disposal of cleaning waste;
  • different decorative papers for each decoration, with the risk of stock becoming obsolescent (and then having to be disposed of).

Energy efficiency and sustainability in production processes

The topic of waste reduction goes hand in hand with that of energy efficiency which is, in turn, an integral part of a manufacturing policy that aims to meet increasingly ambitious sustainability requirements.

All Cefla Finishing solutions are designed to deliver efficiency and sustainability and every Cefla-branded machine or software plays a crucial role in doing so. More specifically, let’s see which patents translate this philosophy into reality.

FCS (Fast Colour Switch) system

Implemented on the Easy oscillating elliptic sprayer, the Fast Colour Switch system can drastically reduce colour changeover times to below 30 seconds (compared to the 150-180 seconds required by traditional methods). This means significant savings in terms of time - up to 30 minutes a day or 2-3 hours a week - and energy, eliminating the need for frequent machine restarts.

Advanced matt finishing

Market demand for deep matt surfaces with soft-touch effects is on the rise. By using UV inks/lacquers and excimer dryers that consume little oxygen, such as the Exydry-Z oven, manufacturers can obtain advanced scratch-resistant, anti-fingerprint matt finishes sustainably.

Roller coating: also available for raised panels

Smartcoater PRO is perfect for reducing lacquer consumption and improving energy efficiency. Raised panel finishing normally requires spray coating, which uses more lacquer. Equipped with a soft rubber applicator roller, Smartcoater PRO performs precision handling of panels with grooves of up to 10 mm, ensuring lower lacquer consumption, fewer manipulations and shorter time to market. To handle thin coatings, Smartcoater PRO incorporates an original, specially designed roller system that can, in turn, be expanded to include lacquer washing and retrieval solutions.

Technologies that reduce machine downtime

Cefla has several solutions that reduce machine stoppages and downtime, one being the Cartesian interpolated-axes iBotic spraying robot, available with one or two arms. Equipped with the Timeskip device, iBotic allows fast, seamless colour changeovers. While one robot arm continues spraying, the other moves to a dedicated colour changeover area, ensuring zero downtime. 
iGiotto instead, enables rapid colour changes with limited lacquer consumption: in practice, colour changeover occurs as one bar enters the booth and the other just-coated one exits. Precise iGiotto trajectories ensure coating application follows the shape of the workpiece: compared to reciprocating, manual application systems, this results in less filter consumption. 
An equally vital tool is iFlow, which can be equipped with rapid colour changeover systems that minimise wash water consumption. All coating booths feature devices that save energy when they’re not actually working. What’s more, an exhaust air recirculation system is available to reduce heat consumption.
Last but not least comes Lineflow, a horizontal door/window preservative application machine designed to reduce air consumption significantly.

The importance of automation in manufacturing

Integrating all these technologies into a resilient, flexible, efficient supply chain means automating processes, reducing human intervention where possible, minimising errors and decreasing downtime.

Let's now dive deeper and identify the impact that each of the solutions highlighted above might have in the context of an automated finishing line. 
With regard to digital printing, automation involves a transformation of the process, not just simple ‘handling’. By integrating the decorating machine into the production planning system, in fact, it’s possible to obtain information on the decoration ‘print queue’ directly from the IT system. This provides highly detailed real-time feedback and lets you control working conditions during the production of individual products.

When it comes to spray and roller coating, however, the advantages of automation are to be found in the handling systems, calibrated to match both productivity and the different processes performed by the various machines on the line.

Lastly, on overhead and floor-mounted lines, the advantages stem from the flexibility of the handling which - thanks to automatic systems - maximises the effectively available space. In fact, it’s possible to arrange product finishing zones in such a way as to converge everything needed to complete the coating process into a single workflow.

Of course, all this is only possible if the ‘ecosystem’ has the real-time instructions needed to control the entire process, step by step. In short, what we’re talking about is information exchange between lines and control systems. Ultimately, therefore, the effectiveness of automation depends on the ability of the machines to generate, send and receive data by communicating with the ERP and the PLM software.

This is why Cefla Finishing has created solutions that can be natively integrated with the company’s ERP systems: output data is logged and exportable to monitor cycle times, with the number of coated pieces sub-divided by colour and by time spent in the drying oven, bar by bar, support by support.

Process-optimizing technology and innovation

Production processes can be optimized by deploying trailblazing technology that revolutionises the way companies work. Just think of the growing weight of applications based on Artificial Intelligence (AI) and the Internet of Things (IoT).

AI helps us improve data quality and refine the forecasting capacity of production systems over time; the IoT, instead, is proving to be a valuable ally for the advanced digitalization of production processes, allowing, for example, manufacturers to create finishing plant ‘digital twins’.

This, in fact, is exactly what the cutting-edge Cefla Finishing software, cCloner, does: it manages line layout and lacquer, heat and electricity consumption. Processing times are calculated on the basis of a production process simulation: this not only lets users identify potential issues but also lets them calculate the total coated surface area managed by a single line.

With cTracker, instead, users can monitor the entire production chain from a single workstation, modifying parameters to make real-time changes to thickness and colour. Used in tandem with cLink, the system can collect inputs and upload them on the company management system to optimize production and reduce consumption.

But what if you’re unable to follow the processes in person at the facility? No problem: the web-based cMaster application gives you immediate access to machine and line data from anywhere in the world via any Internet-connected device.

The benefits of automation and digitalization

At this point it's clear how automated, digitalized production processes can boost productivity, improve product quality and reduce overall operating costs.

Smooth integration of automated systems means manufacturers can perform more efficient, real-time monitoring of lines. In turn, systems (or individual machines) can be dynamically adapted to changing production scenarios or new energy efficiency requirements, without compromising supply chain performance.

Machine-generated data is used to run predictive analyses of line capacity and implement continuous improvement practices along the entire value chain, keeping it upgraded and agile.

This flexibility - combined with enhanced safety and fast returns on investment - is the core benefit of an effective industrial automation strategy.

Employee involvement and continuous training

As mentioned, production process optimization doesn’t just concern technological development: above all, it has to do with people. Despite the common misunderstanding that automation seeks to reduce human resources, the truth is that it actually aims to reallocate them to higher-added-value tasks, leaving more repetitive duties that require no human skill to the machines.

That’s why it’s vital to focus on a cultural, organisational transformation that goes beyond the adoption of new technologies and digital processes to involve everyone in the company. This not only ensures a smoother transition towards a logic of higher production efficiency, it also makes everyone aware of the real benefits this new approach has to offer: such a transformation is a must if we’re to break down the natural resistance to change and promote an informed acceptance of the proposed innovations.

At Cefla Finishing, we’re aware of how delicate that transition can be. That’s why we provide our customers with the skills and professionalism needed to support them, at every stage of the plant life-cycle: from design to technical assistance, from training to change management.
