  • Published : 1992.06.01

Abstract

Sheet metal forming with hydraulic counter-pressure has several advantages compared with conventional drawing, such as higher forming limits, higher accuracy of formed parts and the achievement of complicated formed shapes. About 50 special press machines have already been used in Japan for manufacturing lighting reflectors, aircraft parts and automobile parts. This report descirbes the techniques and the equipment used in the application of process.
