A lead delivery apparatus for a cast on strap machine is arranged to deliver a predetermined volume of molten lead to a mould. The apparatus includes a first needle valve, a second needle valve, and a housing. The housing has a reservoir including an inlet and an outlet. The reservoir inlet is in fluid communication with a molten lead supply. The reservoir is supplied with molten lead during use such that the molten lead in the reservoir is maintained at a constant height.

The invention relates to a single-part feeder body for use as a feeder insert or component of a two-part or multi-part feeder insert in metal casting, having a feeder wall which at least partially delimits a feeder cavity for receiving liquid metal, wherein the feeder wall has an inner surface facing toward the feeder cavity, an outer surface for bearing against a mold material that surrounds the feeder body in certain regions, and a passage opening for the liquid metal into the feeder cavity, wherein the feeder wall has, on the inside, one, two or more material recesses for forming one or more outwardly protruding projections on the metal solidifying within the feeder cavity.

A method including: obtaining a part design file of a part; deriving, from the art design file, a central mold design; determining one or more fill points for the central mold design; and attaching one or more mating connectors to the determined one or more fill points to create a modular part mold file.

A casting apparatus for a cylinder block prevents deformation of a core pin and a cast passage formed by the core pin due to impact of molten metal when casting. Embodiments include a first side mold having a first core pin, a second side mold having a second core pin, a third mold having a molten metal inlet, and a metal dowel. The molten metal inlet is disposed so the inflow direction of molten metal intersects the axial direction of the first and second core pins, which are butted against each other at mold clamping and constitute a core for forming a main gallery for lubricant. The metal dowel is disposed between the molten metal inlet and a butt portion between the first and second core pins so that the butt portion is covered by the metal dowel from the upstream side in the inflow direction of the molten metal.

Disclosed herein is a casting cluster for casting a body of a golf club head made of titanium or a titanium alloy. The casting cluster comprises a receptor and a plurality of runners coupled to the receptor and configured to receive molten metal from the receptor. The casting cluster also includes at least twenty-eight main gates. At least two of the main gates are coupled to each of the runners and each main gate is configured to receive molten metal from a corresponding one of the plurality of runners. The casting cluster further comprises at least twenty-eight molds. Each mold of the at least twenty-eight molds is configured to receive molten metal from a corresponding one of the main gates and to cast a body of a golf club head that has a volume of at least 100 cm.sup.3.

A system for casting by splitting molten materials, and more particularly, for casting molten materials received from a furnace into a plurality of unit forms of a predetermined size, including a body unit, forming a main structure of the system, providing a space where the molten materials are received from the furnace; a side packing unit, disposed at the front and rear sides of the body unit, partially covering the body unit.
