Die casting uses pressure to force molten aluminum into a die. This procedure is used for mass production of parts and requires very little finishing and machining. The main cost of die casting is in the tooling process and the creation of the die. There are two types of die casting: low and high pressure where high pressure requires a complicated die and low pressure uses a simple one.
A benefit of aluminum die casting is its ability to take unusual and geometrically challenging designs and reproduce them flawlessly. There are instances where a part may have delicate features that include unique angles and thin walls somewhat similar to plastic injection molds. Aluminum die casting offers the same types of functions as plastic molds but produces far stronger and more resilient parts. Regardless of the specifications, die casting can recreate the same types of parts as plastic injection molds with the added benefit of a final product that is stronger, lighter, and with dimensional precision
One of the problems related to part production is the need to polish, machine, and complete special handling of the final product. Parts produced by die casting come out of the die in perfect condition and require very little handling other than to be packed and prepared for shipment. Finished parts are smooth and durable able to withstand many years of wear.
Aluminum is one of the most plentiful metals on earth and is a major component in manufacturing. Much of its attraction is due to its many qualities such as resistance to corrosion, thermal and electrical conductivity. Blended with other metals, products or parts manufactured using aluminum die casting retain their stiffness and have an excellent strength to weight ratio.
