Texture on a plastic part serves a variety of purposes from purely esthetic to purely practical. Whatever the goal, there are a few things to remember to ensure that you get the texture you want and that Protomold can effectively produce what you specify. On a surface lying perpendicular to the direction of mold opening, texture is relatively simple. (For features created by a side-action, the same is true for a surface perpendicular to the direction of side-action opening.)<\/p>\n

Surfaces parallel to the direction of mold opening are more challenging. Consider what happens when you drag your knuckles across the surface of a brick. That’s pretty much what happens to a plastic part when its surface is dragged across the textured surface of an opening mold. The solution, of course, is to draft the surface so the mold surface moves away from the part surface as the mold opens. That’s true of any surface parallel to mold opening, but even more critical as the degree of texture increases.<\/p>\n

Here are some guidelines for drafting textured surfaces:<\/p>\n
