Abstract: The invention provides a process for producing a phenolic resin-made pulley having a metal insert embedded therein. The process includes a step of sealing a gate of a mold with a gate-sealing pin, and simultaneously therewith or thereafter moving forward the part or the whole of a movable side die of the mold, which was moved backward, to a predetermined position to mold the pulley, whereby the packing density of the molding material in the cavity is increased.

Abstract: The present invention provides a process for producing a phenolic resin-made pulley having a metal insert embedded therein, which process comprises:setting a metal insert in the form of a cylinder or a circular solid shaft in a cavity of a mold having a movable side die, a fixed side die and the cavity,closing the mold in a state in which a part or the whole 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,preferably sealing a gate of the mold with a gate-sealing pin, and substantially simultaneously with or after the gate sealingmoving forward the part or the whole of the movable side die moved backward, to said predetermined position to mold a phenolic resin-made pulley.This process is particularly effective to mold a phenolic resin-made pulley having holes formed in its disc portion.
