Abstract

PURPOSE: To improve the accuracy in a work of grooving a ring material, by mold forming a groove on the surface, used as a peripheral surface side of the ring material, of a steel plate belt material before it is formed into the round or oval shaped ring material.
CONSTITUTION: In a steel plate belt material a groove 3 is formed by the method of die drawing or mold rolling. The steel plate belt material is formed into a round or elliptical shaped ring material 1a in such a manner that the surface with said formed groove 3 is used as its peripheral surface. Then into the groove 3 of the ring material 1a a material 6 of heat resistance and wear resistance is filled to construct a piston ring. Accordingly, even if the belt material of different shape is a material hard to be machined, an accurate groove can be formed in the product.
