Powder coating paint machines are used in a variety of industries, including automotive, aerospace, furniture, and general manufacturing. They are particularly well-suited for coating complex shapes and surfaces that would be difficult or impossible to coat with traditional liquid paints.
Here is a simplified overview of the powder coating process:
The substrate is cleaned and pre-treated to ensure a good bond between the powder coating and the surface.
The powder coating is fed into the spray gun and electrostatically charged.
The spray gun is used to apply the powder coating to the substrate.
The substrate is then cured in an oven to melt the powder coating and fuse it to the surface.
Powder coating paint machines offer a number of advantages over traditional liquid paint systems, including:
Durability: Powder coating is a very durable finish that is resistant to chipping, scratching, and fading.
Corrosion resistance: Powder coating is also resistant to corrosion, making it ideal for use in harsh environments.

Overall, powder coating paint machines are a versatile and durable way to apply a coating to a variety of substrates. They are particularly well-suited for coating complex shapes and surfaces that would be difficult or impossible to coat with traditional liquid paints.
Powder Coating Process using a Powder Coating Paint Machine
The powder coating process consists of three main steps:
1. Surface preparation
The first step is to prepare the surface of the substrate to be coated. This involves removing any dirt, grease, oil, or rust. The substrate may also be blasted with grit to create a rough surface that will provide better adhesion for the powder coating.
2. Powder application
The second step is to apply the powder coating to the substrate. This is done using an electrostatic spray gun. The powder coating particles are charged positively, and the substrate is grounded. This causes the powder coating particles to be attracted to the substrate and form a uniform coating.
3. Curing
The third and final step is to cure the powder coating. This is done by heating the substrate to a high temperature. The heat melts the powder coating particles and fuses them to the surface of the substrate.
Powder coating is a durable and versatile finishing process that is used on a wide variety of products, including metal, plastic, and wood. It is particularly well-suited for coating complex shapes and surfaces that would be difficult or impossible to coat with traditional liquid paints.
Here is a more detailed explanation of each step in the powder coating process:
Surface preparation
The surface preparation step is critical to ensuring a good bond between the powder coating and the substrate. The surface must be clean, dry, and free of any contaminants. The most common surface preparation methods include:
Chemical cleaning: This involves using a solvent to remove dirt, grease, and oil.
Alkaline cleaning: This involves using an alkaline solution to remove rust and other contaminants.
Grind blasting: This involves using a high-pressure stream of abrasive grit to create a rough surface on the substrate.
Powder application
The powder coating is applied to the substrate using an electrostatic spray gun. The spray gun contains a powder feeder, which dispenses the powder coating into the gun. The gun also contains an electrostatic field generator, which charges the powder coating particles.
When the spray gun is held close to the substrate, the charged powder coating particles are attracted to the surface and form a uniform coating. The powder coating particles are then cured in an oven to melt them and fuse them to the surface.
Curing
The powder coating is cured in an oven at a temperature of approximately 400 degrees Fahrenheit. The heat melts the powder coating particles and fuses them to the surface of the substrate. The curing process typically takes 10-15 minutes.

EMS Powder Coating Equipment Series Filter Cartridge type: Recovery systems are the latest generation state-of-art filter cartridge type powder recovery systems. With an effective cartridge-type recovery system like the EMS Powder Coating Equipment booth, you are assured of at least 98+% (and virtually 100%) of recovery of powder.
Gema Powder Coating Booth
Conventional and often poorly executed recovery booths may not be able to offer more than 75-80% of recovery of reuse while making tall claims of 85 or even 95% recovery efficiencies. This is often the case with poorly designed and copycat cartridge-type powder recovery booths. How the EMS Powder Coating Equipment powder recovery system function:
The powder overspray recovery system is located in the rear section of the powder spray booth (on the face opposite the sprayer). The front section is the coating booth. The workpieces, duly jigged are hung on the jig holder in the coating booth (manually or on a conveyor) and sprayed with powder. A specially designed low-pressure, high-capacity fan sucks air, and the powder overspray through the coating booth to the recovery system in a horizontal flat airflow pattern.
The specially designed PTFE-coated polyester-based filter cartridges entrap virtually all the powder particles. The remaining powder particles, if any, are trapped in the final filters (if installed – optional), allowing virtually clean air to the shop-floor atmosphere through the fan system. Electronically controlled high-pressure reverse pulse air jets located above each filter cartridge regularly and automatically clean the powder-laden filter cartridges.
This throws the powder from the filter cartridges back into the powder spray booth and is collected in the powder bin located under the booth. This process, known as cartridge scavenging is a continuous and online process. The collected powder can be manually (or automated) sieved and reused. Why the EMS Powder Coating Equipment booth:
Highest recovery efficiency – lowest powder cost
Quick color change – save time in color change
Neat & compact – utilizes lowest foot-print on the shop-floor
Easy-to-maintain
Healthy and pollution-free environment
