On the problem of open compression die emerged in production, the part is analyzed and a new processing method is put forward. Cold punching technology is replaced by cold extrusion technology.
The utility model can be manufactured by adopting the method of one-time forming in mold pasting and cold-molding compression.
该产品的制作可采用模具糊制、对模冷压一次成型的方法。
