Bump-off Caps and Molds technology produces plastic caps and lids, or any plastic part, with internal undercuts requiring the need of a mechanical push to eject the part from the core. Bump-off mold designs concentrate on achieving the best cooling possible through the use of multiple inserts, and specialized materials.
A stack mold format for bump-off closures rather than single face mold design will improve the economics of this kind of mold. StackTeck offers part design services providing advise in light weighting the part while maintaining excellent performance of the mold.
