Abstract: GlassOfilled polymers are known to produce considerable wear on the barrels and screws of injection moulding machines.In order to solve the wear problems , it is necessary to use an abrasive wear tester which can simulate the real wear conditions in the injection moulding machine to carry out the simulation test , so that the reasons of the wear can be found and some
measurements can be taken. In this paper the inner wear conditions in the injection moulding machine was analyzed minutely ,and the new developed wear tester that was used to simulate the real wear conditions in the injection moulding machine and the simulation test method were introduced in the paper.

Key words: tester, screw transporter, simulation test
