Plastic spray, commonly known as powder coating, is a surface finishing technique that involves applying a thermoset or thermoplastic powder material onto a surface using a spray gun. This process enhances the durability and aesthetics of plastic products, offering resistance to corrosion, fading, and wear while providing a wide range of color and texture options.

Production Process Description

Step 1: Surface Preparation - The initial stage involves cleaning and preparing the plastic surface to ensure optimal adhesion of the powder coating. This may include washing, sanding, or applying an etching primer to remove any impurities and create a roughened surface for better grip.

Step 2: Powder Application - Using an electrostatic spray gun, the dry powder is uniformly applied to the plastic surface. The charged particles of the powder adhere to the grounded plastic, ensuring an even coat. This step requires precision and control to achieve the desired thickness and finish.

Step 3: Curing - After application, the coated plastic is placed in an oven where the powder melts and chemically reacts to form a smooth, durable surface. The curing process is crucial for solidifying the coating, ensuring its resistance to environmental factors and enhancing its longevity.
