Abstract

The polymer is heated above its melting point (Tf) and cooled to a temperature higher than its crystallization temperature (Tc). The article is formed by feeding the cooled material into compression molding machine (4) while maintaining a temperature close to crystallization temperature (Tc). The article is then cooled and extracted from the mold.
