Abstract
PURPOSE: To obtain a wear-resisting, shock-resisting and denaturation-resisting type head by molding the type head of a single type head typewriter with a mixture of polyamide-66, glass bead and glass fiber in a specific rate.
CONSTITUTION: Polyamide-66 is used as a thermal-plastic resin material, glass bead the particle size of which is 20W40μ and glass fiber are added to it and these are mixed in the rate of 60:33:7 to obtain a material for molding the type head. The mixture is effective to any type head such as golf-ball-shaped, cylinder-shaped or petal-shaped one.
