The design and development of a hydrostatic extrusion apparatus

Abstract

The purpose of this research is to design and construct an experimental hydrostatic extrusion apparatus which has a maximum working pressure of 10 000 kg/cm(2). and to reduce the cost of this extrusion apparatus. The high-pressure extrusion container has been designed with two-layer pyramidal cylinders, and the material used was SKD61 which is cheap and readily available. Different materials and designs for high-pressure seals were tested and analyzed for the best combination performance. Problems in the extrusion processes using this device a ere analyzed and solved, which increased the reliability of the device. The results of extrusion experiments have established that this device is practicable, (C) 2000 Published by Elsevier Science S.A.
