IN ORDER TO PRODUCE A SINGLE HEADED PISTON (32) FOR A SWASH PLATE COMPRESSOR (10), THE FOLLOWING STEPS ARE USED. FIRST, A SHAPED BLOCK (70) OF METAL IS CAST, THE BLOCK INCLUDING A PLURALITY OF UNFINISHED PISTON STRUCTURES (32) WHICH ARE ALIGNED AND INTEGRATED, EACH UNFINISHED PISTON STRUCTURE INCLUDING A HEAD PORTION (32A) AND A NECK PORTION (32B) WHICH ARE AXIALLY SPACED. THEN, THE HEAD PORTIONS (32A) OF THE PISTON STRUCTURES ARE MACHINED. THEN, AN OUTER SURFACE OF THE CAST BLOCK (70) IS ENTIRELY COATED WITH A FLUOROCARBON RESIN. THEN, THE COATED OUTER SURFACES OF THE HEAD PORTIONS (32A) ARE GROUND, AND THEN, EACH NECK PORTION (32B) IS MACHINED TO FORM TWO SPHERICAL RECESSES (35) WHICH FACE EACH OTHER, THE TWO SPHERICAL RECESSES BEING USED FOR SLIDABLY RECEIVING SHOES (23). THEN, THE CAST BLOCK (70) IS CUT TO SEPARATE THE PISTON STRUCTURES (32) FROM ONE ANOTHER. (FIG.6)
