PP MOLDING PROPERTIES 1. Crystalline material, hygroscopicity, easyto occur melt cracking, long-term contact with hot metal easy todecompose. Good li, but the shrinkage range and shrinkagevalue, prone to shrinkage. DENTS, deformations. Cooling speed,pouring system and cooling system should slowly heat, and payattention to control molding temperature. The direction of lowtemperature is obvious. When the mold temperature is lower than 50degrees, the plastic parts are not smooth, easy to produce badfusion, leaving marks, more than 90 degrees prone to warpagedeformation. 4. Plastic Wall thickness must be uniform, to avoidlack of glue, Sharp Angle, to prevent stress concentration, whichcan easily decompose under certain conditions. Common products:Basin, bucket, furniture, film, woven bag, bottle cap, car bumper,etc. .
