The Study on the Influence of Molding Method and Thickness to Part Properties

Article Preview

Abstract:

A large polycarbonate plate molding with different thickness was conducted to investigate the differences between CIM and ICM. The results reveal that increase thickness can significantly reduce part shrinkage, and both part shrinkage and shrinkage difference of ICM are smaller than that of CIM. In addition, This study also shows the optical distortion is close relate to molding method and thickness, both ICM and thinner-wall can reduce the optical distortion.
