Draft angle is needed in most of injection cases. The degree of draft depends on several factors：geometries and wall thickness of parts, material, surface finish, and textures, etc.

Parts can be molded with undercuts. Cams, slides, and lifters can be incorporated into the tooling. For low volume parts, hand loaded inserts can be applied to cut cost.

Tooling lead time range from 1-2 weeks.

Rapid steel mold is a solution for low volume production.Molds designed to simplify the mold frame for saving time and cost.Some tooling can also share the same mold frame with others,but change the mold core as needed.
