Abstract

The friction/wear testing has been carried out for investigating the tribological characteristics between a conventional screw and tribotreated one. The tribotreated screw is manufactured by blasting a fine polymer power to the heat-treated surface of the conventional screw. The injection molding pressure that is developed between the screw and the cylinder has been applied to the rubbing surface on the specimen in a pin-on-disk wear tester. The measured results show that the friction coefficient and wear rate of a tribotreated screw are relatively low compared with the conventional one. This means that the tribotreated screw may be recommended for using an injection mold machine.
