Aluminum Castings Tooling

Aluminum Castings Tooling, or aluminum die castings tooling, are made of alloy tool steels in at least two sections, the fixed die half, or cover half, and the ejector die half, to permit removal of die castings. Modern castings dies also may have movable slides, cores or other sections to produce holes, threads and other desired shapes in the casting. Shot holes in the fixed die half allow molten aluminum metal to enter the die and fill the cavity. The ejector half usually contains the runners (passageways) and gates (inlets) that route molten metal to the cavity. Dies also include locking pins to secure the two halves, ejector pins to help remove the aluminum cast part, and openings for coolant and lubricant.

When the aluminum die casting machine closes, the two die halves are locked and held together by the machine’s hydraulic pressure. The surface where the ejector and fixed halves of the die meet and lock is referred to as the "die parting line." The total projected surface area of the part being cast, measured at the die parting line, and the pressure required of the machine to inject metal into the die cavity governs the clamping force of the machine.

Castings Aluminum Tooling is also known as die casting dies, die casting molds or insert dies. Aluminum die casting tooling also comes in different sizes, shapes, and styles. Casting tooling comes either with a single cavity or multiple cavities. The cost for casting tooling varies for trim dies and cavity inserts.
