One polymer type is referred to as amorphous, which includes materials such as ABS, polystyrene, and polycarbonate, among others. They … See more Fibers are 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. … See more Unlike amorphous materials, semi-crystalline materials have regions of highly ordered, tightly bundled molecular structures. When they … See more 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) … See more When looking at the cross-section of the part, this shrinkage difference occurs when the shrinkage on the top differs from that of the bottom. … See more WebYou will need a Straightedge and Feeler gauges.
