摘要:
A molding method is provided which can further improve transferability and further reduce strain and which is suitable for molding of a product with high accuracy and high quality. The molding method in which a resin material is filled into a cavity formed in a mold and pressurized to mold a product in a predetermined shape, and the method comprises: preparing the mold having a product cavity to mold the product made of a resin, a dummy cavity to mold a dummy product, and a runner by which the product cavity and the dummy cavity are connected; filling the resin material into the product cavity and supplying the resin material to at least part of the dummy cavity; and applying ultrasonic vibration to the resin material in the dummy cavity at predetermined timing.
