Process of high pressure dies casting

High pressure die casting is a widely used processing method in the metal processing industry, so what are the principles and practices of high pressure die casting? This article will introduce you to some information about high-pressure die casting, and I hope it will be helpful to you. We are die casting mold makers, and the content of this article comes from our accumulated work experience and practical exploration.

1 Introduction to the die casting process

Die casting (high-pressure casting) is a near-net-shape technology widely used in the automotive, aerospace, and electronics industries. In the die casting process, molten metal (usually a light alloy) fills the cavity at high pressure and high speed under the action of a punch and cools rapidly to form the final casting. In general, magnesium and aluminum alloys are the primary die-casting materials. The alloy materials of die castings are mainly non-ferrous metals and their alloys, of which aluminum alloys are the most used, while ferrous metals and their alloy die castings have been in a state of stagnation for a long time.

3 Application areas of die casting


Die castings have been widely used in the automotive industry. Die castings are widely used in non-structural parts such as engines (cylinder blocks, cylinder heads, intake pipes, etc.), transmission housings, and wheel hubs. In structural parts, die-casting parts are also used in chassis suspension, body-in-white structural parts (cross beams, shock towers, etc.), covering parts, interior parts, and other components.

Small parts can be produced using the die casting process, but you can also produce large parts on larger tonnage die casting machines.
