The improved design of process tooling structure realized continuous extrusion in common oil press machine. The results show that under powder metallurgical ingot without sintering, the optimum process is as follow, ingot heating temperature is (400±10)℃ , holding time is over 3 h, extrusion ratio is between 90 and 100, die land length is 1.5mm, extrusion speed is about 5 m/min.The utilization ratio of material improves by 10% compared with conventional extrusion and production efficiency improves by about 40%.
