When we decide to make textures and lettering on the plastic parts, depth and draft should be considered, draft for texturing is somewhat dependant on the mold design and the specific mold texture. But don’t worry, because our mold designers can get Guidelines from the mold texture suppliers, I think 1.5°min. per 0.025mm (0.001 inch) depth of texture is a general guideline, sometimes, our industrial designers require a heavier textures such as leather texture on their product design, at this time, the manufacturing requirement will not follow the general guideline I mentioned.
