METHOD FOR PRODUCING A COATED THERMOPLASTIC MATERIAL

摘要

In a method for producing a coated thermoplastic material, thermoplastic material is fed into a twin-screw extruder to produce a homogenous melt as the thermoplastic material is advanced. While the melt is in plastic state an adhesion promoter for a coating material to be applied later or a small amount of a coating material to be applied later as adhesion promoter is added to the melt which is then transferred to an injection mold and allowed to cure to form a thermoplastic body. The thermoplastic body is then coated with the coating material.
