WebbIf the mold temperature is higher than normal during cooling, the plastic melt shrinks towards the wall and therefore pulls a vacuum void on the inside of the part Reduce melt temperature: Cooling after high temperatures might cause the voids. Reduce mold temperature: High mold temperatures keep the melt temperature high causing voids. WebbA new technique called rubber pressure molding (RPM), has been developed to fabricate fiber reinforced plastic (FRP) products from glass fiber/polyester resin. The technique is based on the matching die set, where the die is made from mild steel and the punch from a flexible rubber-like material, i.e., butyl rubber, to apply hydrostatic pressure on the …
