What Is Powder Coating Service For Die Castings

Powder coating service for die castings is a process that applies a dry, powdered coating to metal parts using electrostatic charge. It creates a durable, corrosion-resistant finish, offering superior protection and aesthetic appeal while being more eco-friendly than traditional liquid coatings.

Steps	Description
Surface Preparation	The first step in powder coating is to thoroughly clean the die-cast part. This includes removing oils, dirt, rust, and other contaminants. Proper surface preparation ensures that the powder adheres effectively and forms a durable bond.
Powder Application	The next step is applying the powder coat. The powder is applied using an electrostatic spray process. The powder particles are charged, which helps them adhere to the part's surface, ensuring an even and consistent coverage.
Curing Process	After powder application, the die-cast part is heated in an oven to cure the coating. This process melts the powder, allowing it to fuse and form a hard, durable layer. Curing ensures the powder coat is chemically bonded to the part.
Cooling & Inspection	After curing, the part is cooled to solidify the coating. A final inspection ensures that the coating is uniform and free of defects. Any touch-ups or quality control adjustments are made at this stage to ensure the desired finish.
