ABSTRACT:
A process for producing shaped parts from synthetic and similar workable materials by filling molds under pressure, hardening and removing the articles from the molds. Movable, essentially identical mold carriers are provided with article-related mold inserts preselected for the work cycle and locked in place in the carriers. The forming tool is filled with the synthetic, it is exposed for a given time to certain temperature and pressure conditions, the tool is opened and the inserts are expelled. The form carriers are then outfitted with another set of form inserts while the first set of mold inserts are removed from the molding cycle.
