Polishing

Polishing is a key post-processing step for die casting parts, used to improve surface smoothness, remove minor defects, and enhance appearance. After casting, parts may have mold marks, flash, or surface imperfections. Through mechanical polishing, grinding, and finishing processes, these issues can be reduced to achieve a cleaner and more uniform surface. For zinc alloy and aluminum die castings, polishing improves surface quality and provides a better foundation for plating, painting, anodizing, and other finishing treatments. With proper process control, polished parts can achieve excellent appearance while maintaining dimensional accuracy and production consistency.

Polishing Considerations

Precautions

When polishing, the principle of "slow rather than fast, light rather than heavy" must be adhered to, and the primer should not be exposed.
Carry the wires on your back to avoid hurting people, machines, or tangling the wires. Contact with wires is strictly prohibited.
The polishing wax can be poured on the paint surface and evenly dispersed to prevent the paint surface from splashing.
Before polishing the paint surface, it is recommended to wipe with car wash mud to remove the surface particles and pollutants attached to the paint surface.
When throwing the front cover, cover the front windshield with a large towel or masking film to prevent the polishing wax from sticking to the glass sealing strip and wiper, which is difficult to remove.
The polishing wax is evenly coated on the wool disc or sponge disc to prevent splashing and waste of materials.
After use, place the machine correctly, with the two handles supporting the ground and the hair wheel facing up.
