Powder coating is a technology that in the last few years has conquered always more space in the industrial coating sector, thanks to the numerous advantages in terms of efficiency, quality and sustainability. At Verona Impianti 2002, we design tailor-made solutions to meet the customers’ needs in different sector -from automotive to furniture, from the metalworking and to the electronics industry - placing ourselves as leading suppliers of powder coating systems.
What is powder coating?
Powder coating is a surface finishing process widely used across numerous industrial sectors, thanks to its ability to deliver high-quality, durable coatings that withstand a wide range of mechanical, chemical, and environmental stresses.
This process involves the application of paint powders, usually composed of synthetic resins and pigments, onto metal, plastic or other compatible materials. The powder is sprayed using an electrostatic gun, which electrically charges the paint particles. This step allows the powder to adhere uniformly to the surface to be treated, due to the electrostatic attraction between the particles and the substrate.
Once coated, the part is transferred to a polymerization oven, where the powder undergoes a cross-linking process induced by high temperature, transforming into a continuous, adherent, and uniform film, ensuring a resistant coating. During this phase, the temperature and exposure time in the oven vary depending on the powder's composition and the required technical specifications.
Key advantages of powder coating
1. Sustainability and low environmental impact
One of the main reasons powder coating is becoming increasingly popular is its reduced environmental impact. Unlike solvent-based paints, powders contain no volatile organic compounds (VOCs), which are harmful to both human health and the environment. Additionally, any excess powder that does not adhere to the surface can be recovered and reused, minimizing waste. This makes powder coating an ideal choice for companies aiming to lower their ecological footprint and comply with increasingly stringent environmental regulations.
2. High-quality and durable finishes
Powder coating offers high-quality finishes that are more durable than traditional liquid paints. The coating is extremely durable, resistant to impacts, scratches, corrosion and weathering. For this reason, it is widely used to treat components exposed to particularly harsh working conditions, such as automotive parts, outdoor furniture and metal structures in industrial environments.
3. Efficiency and cost reduction
Powder coating systems are designed to optimize the production process and reduce processing times. The powder is applied uniformly and the polymerization cycle occurs relatively quickly thanks to high-efficiency thermal ovens. In addition, the possibility of reusing excess powder contributes to lowering operational costs. This type of system is ideal for both small and large-scale production, offering flexibility in configuration and production capacity.
4. Flexibility and versatility
A powder coating system can be used for a wide range of applications, from small-scale to large-scale productions. It is suitable for precision coating on small objects as well as for coating large metal structures, such as construction components, industrial furniture, and machinery parts. The technology is highly versatile and can be adapted to different production needs by selecting various types of powders, such as epoxy or polyester powders, depending on the required technical specifications.
Main applications of powder coating systems
Automotive and transport
Powder coating is widely used in the automotive industry to treat metal parts such as such as wheels, frames, and engine components. Thanks to its resistant to scratches, weathering and impacts, it is ideal for the treatment of parts exposed to difficult conditions.
Furniture and design
In the furniture and design sector, powder coating is applied to metal parts of furniture and accessories. The powder coating provides flawless and highly durable finishes, making it ideal for indoor and outdoor furnishings. The wide range of available colours and finishes offers designers great creative freedom.
Metalworking
In the metalworking sector, powder coating systems are used to treat machinery, industrial components and equipment. The powder forms a protective coating that prevents metal corrosion, enhancing the durability of finished products. Its abrasion resistance, combined with the ease of use and maintenance of the systems, makes powder coating a winning choice for this industry.
Appliances and electronics
Powder coating is also employed in the appliances and electronics industry, primarily to protect metal surfaces and ensure a uniform aesthetic. These coatings are particularly resistant to chemical agents and humidity, making products more durable and visually appealing.

How do we design your powder coating plant or machinery?
Designing a powder coating system requires a methodical and tailored approach to meet the client’s specific needs. Our process begins with an in-depth consultancy, during which we listen to the client's requirements and analyse the characteristics of the products to be treated.
Next, we develop a technical proposal that includes selecting the best equipment and technologies, optimizing energy consumption, and ensuring maximum efficiency. Once the project is defined, we proceed with the design and construction of the system, strictly adhering to safety and environmental regulations.
Finally, we assist the client during installation and commissioning, providing continuous support to optimize operations and address any potential issues.
Designing an automatic powder plant
The design of an automatic powder coating plant involves implementing advanced technological solutions to optimize efficiency, quality, and productivity. Automation plays a key role in this type of system, minimizing human intervention, enhancing the precision of the coating process, and increasing production speed.
Every stage, from surface preparation to the polymerization of the coating material, is managed by automated systems that ensure uniform application and minimal material waste. These systems are custom-designed for each costumer, taking into account specific requirements such as available space, production volume, and the type of product to be coated. The result is a highly productive system that delivers consistent performance over time while reducing operational costs through the targeted use of available resources.
Designing a manual powder plant
For manual powder coating systems, the focus is on flexibility and adaptability to meet diverse operational needs. These systems are ideal for medium to small-scale production or companies that require greater versatility in handling products with complex geometries.
The design of a manual system includes the creation of ergonomic coating booths equipped with advanced extraction and filtration systems, ensuring a safe and healthy working environment. Coating is performed using manual spray guns, which allow for precise powder application and customized adjustments to achieve the desired finish.
Although manual systems require human operation, they offer a high degree of control over the quality of the process and exceptional flexibility, making them easily adaptable to various production demands and work volumes.
