The Ultimate in Durable, Chip-Resistant Finishes.

"Orange peel" is a textured surface defect that looks like the skin of an orange. It can be caused by several factors related to your powder coating equipment and process. One common cause is applying the powder coating too thickly. Another is improper curing; if the oven temperature is too low or the part passes through too quickly, the powder doesn't have enough time to fully melt and flow out into a smooth surface before it cures. It can also be a property of the powder formulation itself. To solve this, you need powder coating equipment with precise application controls to manage film thickness and a high-quality oven with stable, uniform heat to ensure a full, proper cure.

Improving transfer efficiency (T.E.)—the percentage of powder that sticks to the part on the first pass—is key to a cost-effective process. The solution lies in your powder coating equipment and technique. First, ensure a solid electrical ground to the part; a poor ground is the most common cause of low T.E. Second, optimize your electrostatic gun settings. A high-quality gun from TIMS COATING allows you to control both the voltage (kV) and amperage (μA) to create a "soft" powder cloud that wraps the part efficiently. Finally, ensure the gun-to-part distance and travel speed are consistent, which is best achieved with an automated or robotic applicator system.

Powder reclamation is the process of capturing unused powder (overspray) in a spray booth and recycling it for reuse. It is the single most important feature for the economic and environmental viability of an powder coating equipment system. A high-efficiency booth from TIMS COATING uses a cyclonic separator to remove over 98% of the overspray from the air. This reclaimed powder is sieved and mixed back in with the fresh powder from the feed hopper. This closed-loop process means that unlike liquid paint where overspray is hazardous waste, powder overspray is a reusable raw material, drastically cutting material costs and waste disposal fees.

Automotive wheels require a finish that is both highly aesthetic and extremely durable, able to withstand rock chips, brake dust, and harsh road salts. For this, powder coating equipment is the ideal solution. The process typically involves a multi-coat system. First, a powder primer is applied for corrosion resistance. Second, a colored base coat is applied. Finally, a clear topcoat is applied to provide a deep gloss and protect against UV rays and scratching. This multi-layer process requires a sophisticated powder coating equipment line with multiple booths and ovens, often with advanced robotics to ensure perfect coverage on the complex geometry of the wheels.
