Abstract

PURPOSE: To obtain the title cam usable for electric clippers, easily mass-produced, with a high dimensional accuracy of diameter, by filling and molding a synthetic resin around a core preliminarily molded to form a circumferential wall layer in two stages.
CONSTITUTION: A glass-fiber reinforced polyamide having a high rigidity is injection molded to form the cylindrical core 11 having a diameter B and a height A. The core 11 is then but into the mold K engraved in the shape of cylinder of given dimensions with the inserting hole 12 and circular hole 13 matched with the semicircular pin 14 and circular pin 15 of the mold K, respectively. A fluorinated polyacetal resin, etc. is injected from the gate G to form the circumferential wall layer 16 of thickness t around the core 11. the driving cam 10 thus obtained has a high roundness and a good cylindricity with the bending sink C on the circumference of the core 11 corrected by the layer 16, thus preventing the slip the joint area between the core 11 and layer 16.
