Doing extra machining on the plastic molds can reinforce aesthetics of plastic injection molding parts to make different changes on the products. Some commonly used texturing methods as below:
- Texturing
- EDM
- Sand Blasting
Texturing
Chemical Etching
Working Method: Use chemical agents to corrode mold material to get required textures.
Characteristics: Less limits to machining. Can be widely applied.
Laser Texturing
Working Method: Set programs on CNC then use laser beams to do texturing.
Characteristics: Eco-friendly, Clean, Automatically, Consistent texturing
Standards:
the US: Mold-Tech
Japan: Nihon Etching
EDM
Working Method: Use electrical discharges to make workpiece form to required shape.
Standards:
VDI 3400
Sand Blasting
Working Method: Blast sands on the surface of workpiece through high pressure air.
Characteristics: Wide application, Can be used in various materials
