ABSTRACT:
Moulded parts are produced by preliminarily making a bend in the moulding zone of a part blank, whose radius is less than a given radius of a part to be produced. The prepared blank is placed in a die and pressure is exerted only on the end edges of the blank along the generant of the bending section. With this method parts can be produced whose walls are as thick as the material of the original blank and this improves the reliability and strength of parts produced with a resultant reduction in the overall weight of these parts. In addition, complex overall shapes of parts without distortion can be produced by applying the above method.
