The influence of PVC material characteristics:
Detail
Poor thermal stability: Accurate temperature control of the mold is required to avoid local overheating and decomposition. The design of the flow channel should avoid dead corners and excessive retention time.
High melt viscosity: requires high injection pressure, and the mold needs to have sufficient strength and stiffness.
Corrosivity: Emphasize the corrosion resistance of mold materials.
Shrinkage rate: The shrinkage rate of PVC is relatively large and may be uneven, and precise compensation is required during mold design.
