Abstract

PURPOSE: To raise air-tightness of a valve seat by making the elemental material for the valve seat by a powder metallurging process and making a sealing treatment mechanically.
CONSTITUTION: When subjecting the elemental material 11 for a valve seat to a press forming using the press molder 12, an expanding or shrinking stress is loaded on the hole and outside portions of the material 11 by the molder 12, whereby causing the holes within a range to be blocked, and furthermore a vertical compression is imposed on both sides of the material 11 by the flat portion 12d of the molder 12, whereby permitting blocking process on the whole portion to be applied. Thus, no residual vacant holes exist in the surface of the both sides A and B and the related vertical sides and therefore an air-tightness almost equal to that of the cast materials can be obtained.
