Internal stress and deformation reduction treatment of a cut end of an extruded plastic product involves heating the cut end face

摘要

The cut surface (24) of the product (5) is heated (26) so that any deformation of the cut end recovers to the original shape and internal stresses produced during the cutting action are reduced. An Independent claim is made for an extruded product with a cut end which has been relieved of internal stress and deformation employing the process.
