Injection Molded Plastic Part Shrinkage, Explained

Image: Plastics Technology Plastic injection molding shrinkage is the contraction of a plastic molded part as it cools in the mold, and even after ejection. There are multiple factors that contribute to the amount of shrinkage a particular plastic part may undergo, such as the type of plastic material, wall thicknesses, and processing parameters. Mold makers must factor in shrinkage and compensate for it when making the injection molds that will make the plastic parts. So how do they know how much [...]
