WebbMethods, systems, and apparatus, including medium-encoded computer program products, for injection molding warp prediction include: obtaining a mold model and measured shrinkage d Learning the concepts behind plastic warpage can lead to developing an approach to reduce it. And with the assistance of technology—such as plastic injection molding simulation software Autodesk Moldflow—engineers can validate those solutions before the manufacturer cuts mold steel. Visa mer One polymer type is referred to as amorphous, which includes materials such as ABS, polystyrene, and polycarbonate, among others. They have a random and entangled molecular orientation in their natural state, much … Visa mer Unlike amorphous materials, semi-crystallinematerials have regions of highly ordered, tightly bundled molecular structures. When they melt, the crystalline structures loosen and the molecules align to the direction of … Visa mer This is when shrinkage rates vary on the part between the regions closest to the gate and regions closest the end of fill (EOF); typically this variance is between the thicker (gate area) and thinner (EOF) areas of the part. One … Visa mer Fibersare often combined into a polymer material to add strength and other properties. When fibers are introduced into the plastic, they may counteract shrinkage effects due to molecular orientation described above. … Visa mer
