15-year precision mould making

     The reason of the mold parts failure is complex and diverse. The main reason is:
Thermal expansion and contraction of the alternating stress, iterative cycles, thermal fatigue crack on the surface of the mould;
Due to the thermal stress and mechanical stress caused by the overall cracking and damage of the die;
Under the action of the pressure and the thermal stress, The mold can produce the crack in the weak point of strength, so that the mould can be broken;
Chemistry corrodes, the machinery wears, the washout corrodes, the melt damages the corrosion to cause the mold to corrode;
By the lock mode, the core pressure and filling pressure to make mold parts is plastic deformation. The reasons for the failure of these dies are complex and diverse.
