Gravity Die Casting
Precision-engineered components for non-ferrous alloys, ensuring dimensional stability and long tool life.
Overview
Gravity die casting is a process that uses a reusable metal mould to produce high-quality non-ferrous metal components — typically aluminium or bronze alloys. The molten metal is poured into the die under the influence of gravity, creating a dense, fine-grained structure with excellent mechanical properties and dimensional repeatability.
Process Characteristics
- Material range: Aluminium, bronze, and other non-ferrous alloys.
- Mould type: Permanent steel or cast iron dies with optional sand or metal cores.
- Dimensional accuracy: ISO 8062 CT6–CT7.
- Surface finish: Good to excellent (Ra 3.2–6.3 μm).
- Production volumes: Medium to high series, up to several thousand units.
Main Applications
This process is widely used for structural and mechanical components where both strength and precision are required. Typical parts include:
- Automotive engine components and housings
- Hydraulic and pneumatic bodies
- Pumps, valves and gear casings
- Marine and industrial hardware
Key Advantages
- High production efficiency and repeatability
- Superior surface finish and mechanical strength compared to sand casting
- Long die life with consistent dimensional control
- Compatible with machining and surface finishing operations
