Effect of Parameters on Properties of Polypropylene in Dynamic Injection Molding

Abstract:

A Novel Self-Designed Dynamic Injection Molding Machine by Screw Axial Vibration Introduced in Plasticizing Process was Used in the Preparation of Polypropylene Standard Specimens. the Energy Consumption in the Molding Process, the Tensile Stress, Impact Stress, Density and Differential Scanning Calorimeter (DSC) of the Specimens were Measured. the Experimental Results Showed that the Maximum Increment of Tensile Stress and Impact Stress of the Specimens are 9.8%and 13.8% Respectively by Screw Axial Vibration Introduced in Plasticizing Process.The Maximum Increment of Density are 0.3%. the Melt Point of Specimens have a Significant Increase of 3°C and the Energy Consumption of the Whole Processing Decreases 6.6% at Maximum.
