钢质塑料模具制造中的若干关注点

Key Points Concerning Manufacturing Steel Mould for Plastics

塑料模具尤其是大型、精密、复杂的成型模,要求精度等级高,使用寿命长。由于制模的难度大、周期长、成本高,在模具的选材、热处理、机械加工等环节均要多加注意。

The moulds for plastics,particularly large-sized,accurate or complex forming moulds,are required to have high accuracy and long service life.The greatest amount of attention should be directed to the material selection,heat treatment,mechanical working and other manufacturing sequences of the moulds because of much difficulty,long period and high cost in making them.
