Our Powder Coating Process

Surface Prep – Sandblasting or Chemical Treatment

The foundation of a durable powder coat lies in meticulous surface preparation. Depending on the material and its condition, we employ either sandblasting to remove rust, old paint, and impurities, or a specialized chemical treatment for a thorough clean and optimal adhesion. This critical step ensures that the metal surface is perfectly profiled and free from contaminants, allowing the powder to bond effectively and prevent future issues like bubbling or peeling.

Application – Electrostatic Powder Spray

Once prepped, the item moves to the application stage, where a finely ground powder made of resin, pigments, and additives is applied. We utilize an electrostatic powder spray method, which electrically charges the powder particles. These charged particles are then attracted to the grounded metal surface, ensuring an even, comprehensive, and consistent coating that adheres precisely to every contour of the item.

Curing – High-Temp Baking in Our 14-Metre Oven

Following application, the coated item enters our state-of-the-art 14-meter oven for curing. Here, it undergoes high-temperature baking, typically between 160°C and 200°C. This heat causes the powder particles to melt, flow out, and chemically cross-link, transforming them into a smooth, continuous, and extremely durable protective layer that is bonded to the metal.

Inspection – Quality Checked for Finish & Coverage

The final and crucial step is a comprehensive inspection. Each piece is meticulously quality checked for both its finish and coverage. Our experts examine the item for any imperfections, ensuring a uniform thickness, consistent color, and a flawless surface free from blemishes, guaranteeing that every product meets our stringent standards for aesthetics and longevity.
