Abstract
A method for treating the surface of a golf club part having a non-smooth surface such as a part which has been cast. Preferably, in those instances where the part is cast, the part is abraded for example by tumbling or by directing a light sandblast against the part to create a low reflectivity surface. Such abrading roughens the golf club part so that greater contrast can be obtained using radiated beam treatment. Surface roughening can also be created by acid etch or other suitable method. The club part is mounted in a beam treatment station to permit projecting a radiated beam on selected areas of the part's surface resulting in the momentary and superficial melting or fusing of the surface which makes such areas less rough and more light reflective than adjacent surface areas. Patterns are formed by causing relative movement between the part and a high energy heat source such as a radiated beam. Preferably the heat source or beam is held fixed and the part mounted on a movable table. Table movement may be controlled by a programmable computer, or other suitable arrangement.
