Verfahren und Vorrichtung zum Innenhochdruckumformen

Following deformation of the metal blank, a pressurized displacement fluid is injected. This is inert with respect to the polymer melt contained. The melt is displaced, leaving an internal layer (20) on the metal molding. An independent claim is included for corresponding equipment. Pressure equipme...

Beschreibung
Zusammenfassung:	Following deformation of the metal blank, a pressurized displacement fluid is injected. This is inert with respect to the polymer melt contained. The melt is displaced, leaving an internal layer (20) on the metal molding. An independent claim is included for corresponding equipment. Pressure equipment (15) is connected to the open end face of the tubular blank (16), to displace polymer melt during deformation.
