<p>A method of manufacturing a valve plate for compressor, comprising the steps of setting punch dies (43) having tip faces (42) formed in irregular shapes on a press (41) and pressing the punch dies (43) against the surface of the valve plate (9) to transfer the irregular shapes on the tip faces (42) thereon so as to roughen the peripheral areas of an intake port and a delivery port of the valve plate (9), whereby the accumulation of foreign matter on the surface of the valve plate can be suppressed when the surface of the valve plate is roughened.</p> |
