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.

This paper presents tribological results of the screw materials, which include the conventional screw and newly developed one. The tribotreated screw is manufactured by applying the polymer power to the heat treated surface of the screw. The injection pressure which is developed between the screw and the cylinder has been applied to the rubbing surface of 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 low compared to the conventional one.
