How is the crack of injection molded products caused
(1) In the process of processing, the pressure is too high, the speed is fast, the filling is more, and the pressure holding time is too long, resulting in large internal pressure, resulting in cracks in the die.
(2) adjust the mold opening speed and pressure during injection process to avoid the failure caused by strong drawing.
(3) Appropriately increase the mold design temperature to make the parts easy to realize demoulding, and appropriately reduce the material temperature to prevent decomposition.
(4) […]
