Whether the material selection of prototype model factory is reasonable or not, will greatly
affect the prototype life and fabrication procedure. Need to make reasonable arrangement
of selecting material according to the different requirements of the prototype structure and
performance.
If product need to be mirror,then should choose good material of prototype industry-P20
electro slag remelting.This material through special craft processing, can satisfy the high
degree finish requirement and process requirements of the prototype. The four slider
material of the cavity part is 45 steel, as the size of the prototype is big,therefore must
must make normalizing treatment after forging blank, eliminate internal stress and
improve machinability performance. After conditioning treatment, after rough machining
adjust to hb240-270, in order to make sure has certain strength and stiffness.
The feedback after actual use fully reflect the correctness and necessity of the heat
treatment process. If every part working condition is good,smoothly movement, the
movable fit surface wear is small,in some extent, will decrease the difficulty of maintain
the prototype ,also prolong its life.
