hdpe mold shrinkage
I'm a seasoned industrial engineer with a keen interest in machine learning. Here to share insights on latest industry trends.
HDPE (High-Density Polyethylene) mold shrinkage refers to the contraction of the material during its cooling phase in the injection molding process. Typically, HDPE shrinkage rates range from 1.5% to 4% but can be influenced by various factors including the resin's flow direction, wall thickness, and processing conditions such as temperature and pressure. To manage shrinkage effectively, it's important for engineers and designers to consider these factors when designing molds and selecting processing parameters. Precise predictions and adjustments are essential in achieving the desired dimensions of the final product. Simulation software can also play a key role in predicting shrinkage and helping to compensate for it during the mold design phase.
