The high pressure casting, also know as die casting, is a complex process that involves injecting molten metal under high pressure into a metal die or mold. One of the main objectives of high pressure casting is to produce high precision and excellent surface finish products. It's technological features include a permanent mold typically made of high quality tool steel, the ablity to cast complicated shapes with fine tolerances and fast cycle times that increase production efficiency. High pressure casting is a technque for making a material strong in its production application by subjecting the metal at pressure between 3000 bar to 4000 bar (43500 psi to 58000 psi). This provides for an element that is both straightforward and effective gains far more dependability than ever before. In all the industries that can use the technology, high pressure casting has been adopted. This means that, wherever parts are needed including mechanical and aerospace industry, these motors parts can be manufactured at low cost. Since some of the technical parameters are difficult to achieve with high pressure casting, so far the use has been limited. For example, such things as aero engine components enclosures and so forth are not yet available via High Pressure Die Casting.
