Device for manufacturing balloon-shaped or hollow bodies from tubular blank or extrudated by blow molding, has molding tool with temperature-controlled hollow mold

摘要

The device has a molding tool with a temperature-controlled hollow mold (3), in which the blank is inflated until the desired shape is attained and is fixed in the mold by warming and subsequent cooling. The hollow mold is designed as a wall having an inwardly defining surface and an outwardly defining surface. The multiple hollow spaces for the circulation of a liquid medium are arranged approximately in the centre between the surfaces. An independent claim is included for a method for manufacturing balloon-shaped or hollow bodies from a tubular blank or extrudated by blow molding.
