Ever wondered how metal toy soldiers were made or how some items turn up to be shaped as they are? Manufacturers don’t mold these shapes like they do for clay pots, instead, the usual process is through die casting. Die casting is a process wherein molten metal is poured under high pressure into a mold cavity to which it similarly takes it shape unless the cavity is provided allowances for the pattern maker to draft, mold or machine the finish product. Alloys that can be used can vary from zinc and copper to magnesium, lead and even tin and pewter.

One of the processes used is by having the metals in high pressure. This is the most common way to cast many other metal alloys, representing about 50% of all production. The low method, on the other hand is used only about 20% of the time for only special products, yet its usefulness increases within time. Other methods are gravity die casting – which amounts to the remaining percentage of production with only a little less left for recently introduced processes – squeeze die casting and vacuum die casting.

Aluminum is a lightweight alloy that has high stability for different shapes and even thin walls while also having good resistance and mechanical properties. With aluminum’s strength in high temperatures and the ability of conductivity in both thermal and electrical, it has a lot of usage for manufacturers of high end products. Each metal alloys has their own special way and this does not go a different way with aluminum. In this process aluminum, the mold is not always destroyed or used only for the purpose of creating a figure closer to the finished product itself. Other manufacturers who use aluminum parts keep the mold permanent as it would provide an outer protection for the aluminum itself. The use the cold chamber process for aluminum because of their high melting points.
