Die-casting process is completed using high pressure to force molten metal into Metal Dies. The Dies can be used to create anything from the simplest thing in your house like a Metal chair leg or coffee table to something as complex as a Transmission Case or engine components for your car engine. Die Casings are one of the highest volume mass-produced items used in the metal working industry.

Die Casting as a process goes back to the mid 1800's started as a manual process related to Casting printer type for a long time but gradually other shapes were developed and by late 1800's early 1900 other types of parts were being made. The process never really took off until the development of alloys many of which are still in use today such as Aluminum, Magnesium and copper.

The die casting process has evolved from using low-pressure injection method to techniques including high-pressure casting with forces exceeding 4500 pounds per square inch - squeeze casting and semi-solid die-casting. This process has enabled the industry to design and build with a high degree of integrity and accuracy many of the products that you see today. Chances are that anything you see in volume is likely being made with some form of Die Casting everything from the kitchen faucet, Die Cast trucks to the most complex items in use today which are required to be mass produced. Die Casting is the process of forcing molten metal under high pressure into the cavities of steel moulds at high pressures. There is only one fundamental difference in die casting machines a hot chamber "the pressure chamber is connected to the die cavity is immersed permanently in the molten metal" or cold chamber "the molten metal is ladled into the cold chamber for each shot". The time required for a die casting cycle can vary from a very quick one second for small components, to two or three minutes for making heavier and more complex items. Die-casting is fastest technique available for producing precise non-ferrous metal parts. Several machining operations would be required or assembly of several parts would be required to make a finished part that the same as the die casting process can create in as little as a few seconds.

Common metals used in die-casting include zinc and aluminum. These are usually not pure metals; rather are alloys, which have better physical characteristics. Die-casting produced parts are durable and dimensionally stable, while maintaining close tolerances. They are also heat resistant. Strength and weight - Die cast parts are stronger than plastic injection moldings having the same dimensions. Thin wall castings are stronger and lighter than those possible with other casting methods. Plus, because die-castings do not consist of separate parts welded or fastened together, the strength is that of the alloy rather than the joining process. Multiple finishing techniques - Die cast parts can be produced with smooth or textured surfaces, and they are easily plated or finished with a minimum of surface preparation.The news come from http://www.bossgoo.com/
