Abstract
A method of producing an insert-molding product in which an insert product is covered with a synthetic resin by arranging the insert product in a cavity of a mold is provided. The method includes holding the insert product by a holding pin, pouring a molten synthetic resin into the cavity, and retracting the holding pin. At least one moving pin is provided adjacent the holding pin. After the cavity is filled with the synthetic resin, the holding pin is retracted and the at least one moving pin is moved to extrude and introduce the synthetic resin into a space where the holding pin used to be positioned prior to its retraction from the cavity.
