METHOD AND DEVICE FOR PRODUCING CRYSTALLISABLE PLASTIC MATERIAL

摘要

A method for manufacturing a crystallizable plastic material is disclosed. The process includes the step of melting an amorphous plastic material, pelletizing the material, crystallizing it and then post condensing the plastic material with the proviso that the plastic material is not subjected to heating after the melting step but prior to the crystallization step and then subjecting the plastic material to sieving after the crystallization step.
