Description (optional):
<p>What is shrinkage in plastic molding?</p> <p><a href="https://www.dgmfmoldclamps.com/what-are-the-effects-of-injection-temperature-and-speed-on-product-shrinkage/">Shrinkage</a> is the contraction of a plastic molded <a href="https://www.dgmfmoldclamps.com/injection-mold-components/">component</a> as it begins to cool after the injection process. All plastics shrink as they cool from viscous liquids to solids and every type of plastic shrinks in a slightly different way.</p> <p>If the injection mold temperature is too low, the melt glue will be cooled too fast, and the thicker glue position far away from the water inlet will be blocked by the middle part of the <a href="https://www.dgmfmoldclamps.com/coolings/">cooling</a> too fast, so the distant part will not be fully replenished by the melt glue, which will make the shrinkage problem more difficult to solve, and the shrinkage problem of thick and large injection molded parts is especially prominent.</p>
