[0002] The runner and gate of the pinpoint sprue mold are not on the parting line, but are usually directly on the product, so an additional set of sprue parting lines must be designed, which is more complicated to design and more difficult to process. Generally, the pinpoint sprue system should be selected according to the product requirements. The fixed mold part of the pinpoint sprue mold is generally composed of three steel plates, so this type of structural mold is also called a "three-plate mold". The three-plate mold is the simplest structure among pinpoint sprue molds.
