What is High Pressure Die Casting?
High-Pressure Die Casting (HPDC) is a versatile manufacturing method for producing various product forms. The process forces molten metal at high speed and high pressure into a closed steel die cavity. The die is mounted to the die casting machine’s platens with its stationary and moving halves. With its injection end using hydraulics and pressurized gas to move a piston forward, the die casting machine injects the molten metal into the closed steel die. Utilizing hydraulics and mechanical toggles, the clamping end absorbs the injection pressure and holds the die shut while the part solidifies. The process can turn molten metal into a solid near-net-shape part in seconds, showcasing its versatility in various applications.
The three main metal groups used in this die casting process are aluminum, zinc, and magnesium. NSD supplies all three metals and employs cold and hot chamber high-pressure die casting turn-key solutions.
How does the high pressure die casting process work?
In a high pressure die casting process, molten metal or metal alloy is injected at high speed and high pressure into the mould.
Horizontal high pressure die casting machines ensure the die closes completely. These are rated by how much closing force they can apply and, for LK Diecasting machines, that can range from 30 to 20,000 tonnes.
Depending on the metal being used, the injection unit that fills the mould can either be hot chamber or cold chamber. In hot chamber die casting, the metal is held within the diecasting machine itself, then drawn into the chamber and forced into the mould by the injection piston. These parts of the machine are in constant contact with the molten metal.
In cold chamber process the metal is first melted in a separate furnace and transferred to a holding furnace, then poured into a shot sleeve and injected into the mould. LK offers a wide range of cold chamber high pressure die casting machines.
Advantages of High-Pressure Die Casting
High-Pressure Die Casting can produce large, light-alloy parts in high volumes at great speed and efficiency. The HPDC process also delivers parts with superior surface finish, excellent uniformity, and optimum mechanical properties.
Another advantage of High-Pressure Die Casting is that it generally doesn’t require much machining thanks to excellent dimensional accuracy and smooth surfaces. Compared to other manufacturing processes, high-pressure die casting is an efficient, economical process that:
Produce strong, lightweight parts that require less machining than fabricated parts
Create complex and intricate shapes in a single piece, eliminating the need for assembly or welding
Offer a more broad range of shapes than other metal manufacturing techniques
Achieves close tolerances

Advantages of the high pressure die casting process
High pressure die casting technology can produce very large light alloy parts, in high volumes and great speeds.
These machines deliver light alloy parts with high precision, superior surface finish, excellent uniformity and optimum mechanical properties.
The high pressure die casting process can also produce components with thin walls and "co-cast” parts with different types of inserts, such as screws and liners, that then become an integral part of the product itself.
Application
Cold chamber high pressure die casting technology is ideal for production of a diverse range of aluminium and magnesium automotive castings such as engine blocks, gearbox casings, oil sumps, engine mounts and structural parts like cross-car beams.
It is widely used in other sectors to manufacture components in applications that range from the simplest – a lighting component – to the most demanding, such as aerospace engine parts.

Die casting
Die casting is a metal casting process that is characterized by forcing molten metal under high pressure into a mold cavity. The mold cavity is created using two hardened tool steel dies which have been machined into shape and work similarly to an injection mold during the process. Most die castings are made from non-ferrous metals, specifically zinc, copper, aluminium, magnesium, lead, pewter, and tin-based alloys. Depending on the type of metal being cast, a hot- or cold-chamber machine is used.
The casting equipment and the metal dies represent large capital costs and this tends to limit the process to high-volume production. Manufacture of parts using die casting is relatively simple, involving only four main steps, which keeps the incremental cost per item low. It is especially suited for a large quantity of small- to medium-sized castings, which is why die casting produces more castings than any other casting process.[1] Die castings are characterized by a very good surface finish (by casting standards) and dimensional consistency.
History
Die casting equipment was invented in 1838 for the purpose of producing movable type for the printing industry. The first die casting-related patent was granted in 1849 for a small hand-operated machine for the purpose of mechanized printing type production. In 1885 Ottmar Mergenthaler invented the Linotype machine, which cast an entire line of type as a single unit, using a die casting process. It nearly completely replaced setting type by hand in the publishing industry. The Soss die-casting machine, manufactured in Brooklyn, NY, was the first machine to be sold in the open market in North America.[2] Other applications grew rapidly, with die casting facilitating the growth of consumer goods, and appliances, by greatly reducing the production cost of intricate parts in high volumes.[3] In 1966,[4] General Motors released the Acurad process.[5]
