When Rapid Cooling and Heating Device is applied to injection products, Influence of Operation Condition on the Warpage of Plastics
초록
영어
Warpage of injection molded product is caused by non-uniform shrinkage and residual stress. A method of removing uneven molding shrinkage and residual stress is to remove the defective factor to Uniform cooling of products. Warpages for part designs have been investigated in this study according to the injection molding conditions for amorphous ABS and crystalline PP by the rapid cooling and heating system. Experimental results showed that the crystalline resin was more warped than amorphous resin, Warpages have been observed in the regions of the part, near gate region and flow direction region.
