Designing a painting system is a complex process, that requires detailed analysis and meticulous planning: every detail must be carefully evaluated, to ensure that the system meets the production needs and advanced requirements of the the customers.

In this context, relying on a company with consolidated experience and skills, such as Verona Impianti 2002, is vital for the success of the project. A team of specialised technicians can provide complete support right from the design phase, helping to choose the most suitable technologies and equipment and to customise solutions based on specific needs.

There are many factors to consider during the design phase of a new coating system and, for the success of the project, it is essential to be able to satisfy them all. Let's explore together what they are:

1. The type of paint you need to apply

The first crucial decision in the design of a coating system concerns the type of paint to be applied: it can be powder or liquid, with formulations dedicated to the different applications – either spray or dip, such as cataphoretic coating.

Each of these processes has its own specific characteristics and advantages, so the choice of the most suitable method depends on the peculiarities of the components to be treated – such as material, size and structure – and on the production goalsof the company.

2. The materials you want to coat

The type of substrate you need to coat significantly influences the choice of the equipment and the related process. Each type of material has specific requirements in terms of surface preparation, paint adhesion and final finish. So, in order to achieve optimal results, it is therefore essential to consider the material properties.

  • Metal: The coating of metals requires a careful surface preparation, either through a mechanical (shot blasting) or chemical (phosphating/surface conversion) pretreatment phase that ensures a good adhesion of the paint, followed by an adequate corrosion protection and chemicals resistance.
  • Plastics: Painting plastic materials can be complex, due to their chemical nature. It is then necessary to use specific primers to improve adhesion and prevent defects. The choice of the paint must consider the lower rigidity and the thermal expansion of the material.
  • Wood: Wood requires a preparation that includes sanding and the application of sealants, to even out paint absorption. Varnishes must offer the protection from humidity and UV rays, while maintaining the aesthetic appearance of the wood.
  • Glass: Coating glass requires special paints that adhere to its smooth, non-porous surface. It is important that the paint can withstand scratches and abrasions, to maintain the transparency and shine of the glass.

3. The production output and the capacity of the plant

The quantity of products to be painted daily and their size influence the configuration of the coating lines to be installed. A detailed analysis of the expected production capacity is essential to correctly size the plant.

  • Production volume: The analysis of the required production capacity determines the number of units to be painted daily or per shift. High-volume production facilities require automated coating lines and efficient conveyor systems, in order to maintain a continuous flow of material.
  • Parts dimensions: The dimensions of the products influence the design of the system. Large workpieces require, for example, large painting booths and robust handling equipment; while smaller components can be processed in batches, with specific support systems to optimise space and reduce processing times.

4. The required space

The physical space available within the plant represents a critical factor in the design of a painting system. Coating lines have often a considerable footprint, especially if they include several areas dedicated to specific phases of the production process.

First of all, it is necessary to provide adequate space for surface preparation, as the process may require large machinery such as shot blasting machines or pre-treatment tunnels with multiple stages. Even the painting booths, as well as the drying and curing or baking ovens, must be designed basing on the size and quantity of the pieces to be treated.

Finally, handling systems, such as monorail, power&free or carriage conveyors, require adequate space to transport the pieces between the different areas of the plant.

5. The current regulations

Coating plants must be designed to minimise the emission of VOCs (Volatile Organic Compounds) and other pollutants, which can have a negative impact on the environment and workers' health and safety.

To ensure regulatory compliance, it is necessary to implement effective air treatment systems to reduce the concentration of paint vapours and solvents in the air. These systems must be designed to ensure an adequate air flow and prevent the accumulation of hazardous substances.

Furthermore, it is essential to provide filtering systems to treat the air extracted from the painting booths and drying ovens. These filters must be able to capture paint particles and chemical vapours, reducing the environmental impact of the system.

The wastewater management is another crucial aspect. Coating plants produce waste that cannot be dispersed into the environment, such as paint residues and used solvents, which must be collected and disposed of in accordance with current regulations. It is important to implement waste management procedures that minimise the risk of environmental contamination and ensure worker safety.

Finally, it is essential to ensure the safety of workers through the adoption of preventive measures and personal protective equipment (PPE). This includes training staff on correct work procedures, the use of respiratory masks, gloves and protective clothing, and having emergency plans in place to deal with any incidents.

6. The energy efficiency

Energy efficiency is an important factor in reducing the operating costs and the environmental impact of a painting plant. Optimising energy consumption not only helps reduce operating costs, but also improves the sustainability of the system.

One way to improve energy efficiency is to implement heat recovery systems that allow the heat generated by ovens and other equipment to be recovered and reused, reducing the need for additional energy for heating. At the same time, high performance insulation (i.e. low thermal conductivity) and heat retention systems, such as air curtains, closing doors, economisers, etc. must be used.

The use of energy-efficient paints and coatings is another crucial aspect. Solutions that require shorter drying times or lower temperatures for curing can significantly contribute to reducing the energy consumption of the plant.

Optimising production cycles is equally important. This includes scheduling operations to reduce downtime and maximise the efficiency of the lines. Automated control systems can help to continuously monitor and adjust processes, ensuring efficient use of resources.

7. The desired quality of the finish

The quality of the desired finish is a determining aspect in the design of a coating system. It directly influences the choice of the equipment and painting processes to be adopted. The coating must ensure a uniform, high-quality finish on all treated pieces, regardless of the complexity of their shape. Furthermore, painted surfaces must also resist atmospheric and chemical agents, to ensure the durability of the finished product.

8. Maintenance and technical support

A crucial aspect in designing a painting system is maintenance planning and after-sales technical support. A well-designed system must provide easy maintenance and effective technical support to ensure continuous and reliable operations over time.

Scheduling preventive maintenance is essential to minimise downtime and keeping equipment in peak operating condition. Choosing quality equipment, with reliable and easily replaceable components, helps reduce maintenance costs and downtime.

Furthermore, it is important to have access to competent and timely technical support in the event of problems or failures. A reliable company must be able to provide remote assistance or rapid on-site interventions to resolve any problems and ensure the continuity of the painting operations.

H9. Implementation and operational costs

Accurately evaluating implementation and operational costs is critical to ensure a sustainable investment in the paint shop. This includes both initial installation as well as ongoing operating costs over the life of the system.

It is important to consider not only the cost of purchasing equipment and technology, but also the costs associated with site preparation, installation, staff training and the commissioning of the facility. A detailed cost-benefit analysis helps you make informed decisions and optimise the allocation of financial resources.

Additionally, it is critical to evaluate ongoing operating costs, including energy consumption, consumables, maintenance and technical support.
