Plastic Molding Design

Pay attention to the three key factors related to plastic injection raw materials

Plastic shrinkage 1, Causes of shrinkage Thermal expansion and contraction. Melt crystallization (the higher the crystallinity, the more severe the melt shrinkage). Molecular orientation (in general, molecules are always oriented along the flow direction, for unreinforced materials, the melt shrinkage in the flow direction is always greater than the vertical direction; for reinforced materials, the [...]

Tolerance Analysis for the Molding of Kitchen Appliance Surfaces Design and Modification

This is to illustrate how to use tolerance analysis as a tool to ensure that a kitchen appliance molding design meets its mass production requirements and customer expectations for component assembly, product appearance, and product performance. The Benefits of Tolerance Analysis Before mass production Verifies a design will achieve the desired level of quality Ensures [...]

Shrinkage and warpage in the molding desing

  Shrinkage and warpage Why do they occur? Shrinkage is inherent in the injection molding process. Shrinkage occurs because the density of polymer varies from the processing temperature to the ambient temperature. During injection molding, the variation in shrinkage both globally and through the cross section of a part creates internal stresses. These so-called residual […]
