ABSTRACT:
A disk-shaped object of synthetic thermoplastic material has contact surfaces on opposite sides that possess a rough texture. In a method for production of the disk-shaped object, synthetic material is injected under pressure in a plasticized state into a cooled molding tool and removed therefrom after a cooling phase, the molding tool having correspondingly rough molding surfaces to form the rough contact surfaces of the object.
