This article deals with the evaluation of material wear of injection molds made of aluminium alloy Alumec 89 and copper alloy Moldmax HH in friction couples with polymer materials with various filler contents. The friction relations in injection molding were simulated in an adhesion dry wear test using an Amsler machine, with an area contact of the friction couple materials. The wear intensity was evaluated by determination of friction coefficient and relative wearing by the mass loss. Surface morphology changes of evaluated alloys after wear and the thermal conditions in particular friction couples were analyzed simultaneously.
