What is High Pressure Diecasting?

Diecast meaning takes us back to the 18th century when die-casting was first introduced. Initially, diecasting was used for the creation of letters or punctuations for movable typewriters. It was the 1880s when the basics of casting were first studied, and a die cast factory was established. At first, materials used for the die-casting process were tin or lead, but later removed by aluminium and zinc for their numerous benefits. There are various types of casting, such as low pressure die casting, hot chamber process, cold chamber process and high pressure die casting. 

High Pressure Die Casting

Hpdc casting is a casting process that utilises high pressure to inject molten metal into a pre-designed mould, resulting in the production of complex-shaped components with excellent surface finish. This technique has gained great popularity across industries due to its ability to produce large quantities of parts at a rapid pace while maintaining consistent high quality. The impact of high pressure die casting die on the manufacturing industry cannot be overstated. 

Impact of High pressure Casting on the Industry
