Abstract
Powder metallurgy parts are used in automobile industry more and more widely.Only automatic forming presses are used,it's possible to realize mass production,costs reduction,efficiency improvement.But automatic forming press set is commonly high,and mould length size is larger.The production problem can be solved effectively by mould design of PM worm wheel shaft sleeve in automobile engine due to mould manufacturing difficulty.关键词
