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

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.

"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.

For most metal applications, a finish applied with powder coating equipment is significantly more durable than traditional liquid paint. The reason lies in the chemistry and thickness. Powder coating is applied much thicker than liquid paint, providing a more robust barrier against physical impacts. More importantly, the powder is made of thermal-set polymers that, when cured in an oven, cross-link to form a very hard, dense, and plastic-like shell. This finish is highly resistant to chipping, scratching, abrasion, and fading. While some high-performance liquid paints are very tough, for general industrial and consumer products, powder coating holds a clear advantage in durability.

Powder coating equipment works through a multi-stage process. 1. Pretreatment: A metal part is first thoroughly cleaned and prepared in a series of chemical washes. 2. Application: The part is then moved into a spray booth. An electrostatic spray gun applies a positive charge to particles of a dry, paint-like powder and sprays them towards the negatively grounded part. The opposing charges cause the powder to adhere to the entire surface. 3. Curing: The powder-covered part is then moved into a curing oven. The heat melts the powder, causing it to flow together and form a smooth, liquid-like layer. As it continues to heat, it chemically cross-links to form a hard, durable, and solid finish.
