Abstract

Das Grundprinzip besteht darin, die von innen auf das Umformwerkzeug (1) einwirkenden Druckkräfte, d.h. den "Umformdruck" zumindest teilweise durch einen "Gegen- bzw. Stabilisierungsdruck" zu kompensieren, der von außen auf das Werkzeug (1) aufgebracht wird. Aufgrund der geringeren mechanischen Beanspruchung des Umformwerkzeuges (1) kann es weniger massiv und somit kostengünstiger ausgelegt werden.
