The plastic mold trial contents (4)--setting optimized Clamping force

Usually we forget to pay attention to the clamping force in the mold trial. In fact, this clamping force affect the air escaped and flash created. How to set an optimized clamping force for the injection machining.

• set 90% of the clamping force for the injection machining after the hold pressure and hold pressure switch are set to most optimized, to produce 3 shots, record its weight accordingly

• Reduce the clamping force 5 Tons each time, produce the parts 3 shots accordingly, record their weight

• Until the weight increase suddenly, weight increase around 5% and create the flash at surround of the part
