What is High Pressure Die Casting?

High pressure die casting is an extremely efficient manufacturing method for producing a variety of product forms. The process forces molten metal into an enclosed steel mold cavity at high speed and pressure. The mold has fixed and movable halves, both mounted on the platen of the die casting machine. The die casting machine has an injection end that uses hydraulic pressure and pressurized gas to move a piston forward, injecting molten metal into a closed steel mold. The pressure die casting machine also has a clamping end that utilizes hydraulic and mechanical toggle to absorb the injection pressure and keep the mold closed while the part solidifies. The process turns molten metal into solid, near-net-shape parts in seconds.


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:
● 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 that other metal manufacturing techniques.
● Achieves close tolerances.
