摘要

The method involves effusing two-piece negative forms (1,2) of a plastic head that can be manufactured with hardening cold castables consisting of polyurethane. The two parts of the negative form are added. The added negative form is brought in a position for casting with which the neck of the plastic head which can be casted lies at the top. The casted periwig plastic head is reworked from outside as a possible burr is removed. Independent claims are also included for the following: (A) a negative form for executing a method for manufacturing a plastic head (B) a plastic periwig head.
