Molded parts It refers to the parts that make up the mold cavity.Mainly include: punch, die, core, forming rod, forming ring and inserts and other parts.

The pouring system refers to the plastic flow channel in the mold from the nozzle of the injection molding machine to the cavity.Ordinary pouring system is composed of main runner, branch runner, gate, cold slug hole and so on.
