Castings Aluminum Company provides and manufactures die casting molds and die casting tooling, or aluminum die casting mold 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 die casting molds and 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 clamped together by the machine's hydraulic pressure. The surface where
the ejector and fixed halves of the die meet and clamp 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.
Die Casting Molds and die casting tooling are also known as die casting tooling dies, die casting mold bases with insert dies. Unit dies are another common type
of die casting tooling. Aluminum die casting tooling also comes in different sizes, shapes, and styles. Die Casting Mold tooling comes either with a single cavity
or multiple cavities tooling and also family dies. The price for a die casting mold or tool varies as well as for die casting trim dies and die casting cavity inserts.
Die Casting Molds and Die Casting Trim Dies
Aluminum die casting Trim Tooling. Aluminum Parts sometimes require die casting trim tooling. After a die casting part is manufactured with the tooling in
the casting machine, a die casting trim tool called a "die casting trim die" is used to cut or sheer the extra aluminum surrounding the parts.
Die casting trim dies may save as much as 15% in the part costs by speeding up the part production process. Die casting trim dies cut or
shear extra metal from die cast parts. The trim dies sits or is mounted into a trim press that hydraulically forces the two halves of the trim die
together to sheer material with several tons of pressure.
