Coating optimizes wear resistance

Bexalit coating for twin screws reportedly shows up to 100 percent higher resistance to wear compared with nitrided screws. Due to the increasing amount of abrasive and corrosive ingredients in plastic materials, as well as increased twin-screw extruder outputs, there is a need for higher wear resistance.

Because of their complex screw geometry, twin screws can be coated only with a highly sophisticated automatic process such as plasma powder deposition (PTA). Low blending, controlled preheating and cooling during the coating process, and the perfect metallic bond formed between the protective coating and the basic material prevent tension cracks from forming in the functional layer. Subsequent plasma nitration helps keep the Bexalit screw and the barrel wall running smoothly together.
