Calculating Plastic Mold Shrinkage
What is Plastic Mold Shrinkage? Plastic injection molding shrinkage is the contraction of a plastic part as it cools after injection molding. Material science tells us that, in most cases, matter will expand as it warms up and contract as it cools down. Plastic is no exception to this rule. Injection molding is the process of forcing molten plastic into a metal mold. The molten plastic will solidify into the shape tooled into the mold. As the plastic cools it will [...]
