For the injection parts surface finish, DML manages with three ways done on mold:
Polishing surface, EDM surface and Texture surface.
1.For the polishing surface:
It is relatively simple, these tools can be used: sandblasting, whetstone, sandpaper, diamond paste.
2.For the EDM surface:
EDM will make the surface of the finished product matte effect, due to the processing electrode and the mold surface will produce a very small arc erosion on the mold surface which causing the surface with many extremely small potholes.
3.For the texture surface:
Discharge also has the form and number, usually based on processing conditions and machine manufacturers to make the distinction between specifications. MT specifications is the most commonly used one. The bigger the number, the thicker the texture pattern. Pls see details in following chart:
|Serie No.||Texture Depth||Draft Angle|
You can select any pattern from chart or supply us with a sample texture.https://www.dml-mould.com/
