In today's era of rapid industrialization, plastic molds have become an indispensable part of the industrial era. So today Jimei Injection Molding Factory will tell you about the surface treatments commonly used in injection molds.
1. Polish
Mainly by cutting, the surface of the material is plastically deformed to remove the polished convex part to obtain a smooth polishing method. Generally use whetstone strips, wool wheels, sandpaper, etc., mainly manual operation.
2. Thin Fire Texture
After EDM machining, lines are left on the plastic mold. Generally, electrode processing fire patterns are not specially made, because the cost is relatively high.
3. Chemical etching (Texture)
Soak the spray patterned mold and the mold with the film attached in the prepared chemical solution to corrode the bright part of the mold, and the surface of the mold will turn black after corrosion.
4. Plating
It is to use electrolysis to deposit metal or alloy on the surface of the workpiece to form a uniform, dense and well-bonded metal layer process, which is electroplating.
5. Sand Blasting
Sandblasting is a process of workpiece surface treatment, which uses compressed air as power to form a high-speed jet to spray the spray material onto the surface of the workpiece to be treated, so that the appearance or shape of the workpiece surface changes.
