A Cleaner, Safer, and More Efficient Way to Coat.

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.

"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.

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.

A major innovation in the world of powder coating equipment is the development of low-temperature and UV-cured powders. Traditional powders require curing temperatures of around 180-200°C, which limits their use to metal substrates. New formulations can now be cured at temperatures as low as 120°C, or with high-intensity Ultraviolet (UV) light with very little heat. This breakthrough opens up the possibility of using durable powder coatings on heat-sensitive materials like wood, MDF, and plastics. The future of powder coating equipment involves integrating specialized IR and UV curing ovens into the production line, a technology that TIMS COATING is at the forefront of developing.
