Developing of low capacity hydraulic presses on the base of pressing technology improvement

A new process has been developed for manufacturing precise shapes and low-cross section tubes. A non-driven ram and a press-tool used extend the capabilities of backward extrusion and the control over speed conditions. New hydraulic presses make it possible to rise the output and dimensions of shapes, to intensify pressing of easy and difficult-to-deform aluminium alloys over a wider range.
