초록

A method and system for producing hollow rib structures for trim components and panels using gas assisted injection molding. Movable insert members are provided in the mold cavity, particularly at the ends of the structural rib members. After the plastic material is injected into the mold cavity, the plastic is packed in the mold, and the insert members are locked in position. Selectively activatable locking mechanisms are used to lock up the insert members. Thereafter, gas or another fluid is introduced into the rib members in order to provide hollow ch...
