Method for manufacturing polymeric hollow body by fluid injection technique, involves creating hollow space by displacement of flowable molding material through fluid that is provided as two or multiphase mixture in form of atomized mist

摘要

The method involves creating a hollow space by displacement of flowable molding material through a fluid. The fluid is provided as two or multiphase mixture in the form of an atomized mist. Mist components are changed before, during and after hollow space formation of its physical state. A multiparts and closed molding tool is attached by under volumetric injection of a flowable molding compound in a molding hollow space, where thermoplastic melts and crosslinking molding compositions, such as elastomers or duroplastics, are used as flowable molding material.
