Abstract:
A process for producing a phenolic resin pulley having a metal insert embedded therein, which process comprises:setting a metal insert having a form of a cylinder or a circular solid shaft in cavity of a mold, said mold having a movable side die, a fixed side die and the cavity; closing the mold in a state in which at least a part of the movable side die has been moved backward by a given distance from its predetermined position to be taken when a pulley to be produced has a final shape; injecting a phenolic resin molding material into the cavity to fill the cavity with the molding material; and sealing a gate of the mold with a gate-sealing pin, and simultaneously therewith or thereafter moving forward the part or the whole of the movable side die, which was moved backward, to said predetermined position to mold said pulley, whereby the packing density of the molding material in the cavity is increased.
