How to choose surface finish for plastic injection molded parts?

1. You can have the mold surface polished, and then the parts will be glossy.

2. You can also have the mold surface textured. You can choose the texture type. Then the mold surface is rougher than usual, so the demolding is harder than polished, so when you try to add texture, pay more attention to the mold draft. If the mold draft is not big enough, not textured, or try to find the finest texture type, like bead blasting.
