High Pressure Die Casting
High-efficiency casting process for complex and thin-walled components with excellent dimensional accuracy.
Overview
High Pressure Die Casting (HPDC) is a manufacturing process that injects molten metal under high pressure into a hardened steel mould, producing parts with exceptional precision, surface finish, and repeatability. It is one of the fastest and most economical casting methods for large-scale production of non-ferrous components, especially aluminium, zinc, and magnesium alloys.
The HPDC process is ideal for parts with thin walls, tight tolerances, and complex geometries, where both strength and dimensional stability are essential. The result is a near-net-shape product that requires minimal machining and delivers consistent quality over long production runs.
Process Characteristics
- Injection pressure: Typically between 700 and 1,200 bar depending on alloy and part size.
- Alloys: Aluminium (AlSi9Cu3, AlSi10Mg), Zinc (Zamak), and Magnesium.
- Mould type: Hardened steel dies with automated lubrication and cooling systems.
- Cycle time: 30 to 90 seconds, ideal for high-volume production.
- Dimensional accuracy: ISO 8062 CT5–CT6, allowing extremely tight tolerances.
- Surface finish: Ra 1.6–3.2 μm, often suitable for direct painting or coating.
Main Applications
Due to its precision and speed, High Pressure Die Casting is widely used in industries requiring complex, lightweight and high-strength parts. Common applications include:
- Automotive components such as gearboxes, housings, brackets and engine covers
- Electronic and electrical enclosures for consumer and industrial devices
- Hydraulic and pneumatic components
- Lighting fixtures and heat dissipation parts
- Structural parts for aerospace and e-mobility applications
