The Effect of Pressure on Warpage of Dumbbell Plastic Part in Injection Moulding Machine

The optimization of processing parameters on warpage of polypropylene (PP) in the application of injection moulding machine was studied. The appropriate parameters were adjusted to reduce the warpage defect on the tensile test specimen of dumbbell. The type of injection moulding machine used in this...
