金属零件的冷挤压的工艺是少无切削加工工艺之一;它具有高产、优质、低消耗的特点,在我国的各个工业部门中已逐步采用。世界上各工业发达国家也都很重视这一工艺技术,并在机械工业中尽量采用,日本就是这样。早在第二次世界大战后的恢复期间,日本就很快从别国引进冷挤压工艺及设备专利,并大量用于生产,取得很好的效果。近十多年来,在此基础上发展了具有日本特色的冷挤压工艺及理论,制造了具有日本特色的冷挤压压力机销售世界各地。
Cold extrusion of metal parts is one of the few non-cutting process; it has the characteristics of high yield, high quality, low consumption, has been gradually adopted in various industrial sectors in China. The world’s industrialized countries also attach great importance to this process technology, and try to adopt in the machinery industry, Japan is the case. As early as the post-World War II recovery, Japan quickly imported cold-extrusion processes and equipment patents from other countries and used it in large quantities for good results. Over the past decade or so, based on this, the company has developed cold-extrusion processes and theories with Japanese characteristics and manufactured cold-extrusion presses with Japanese characteristics for sale all over the world.
