Industries Relying on Complex Sand Casting Capabilities

Complex geometry sand casting is essential for industries producing large, structurally intricate components in low to medium volumes, where permanent tooling for other methods is cost-prohibitive. Its ability to create massive parts with intricate internal cores and passages makes it indispensable across several key sectors.

Aerospace and Aviation

The aerospace industry leverages sand casting for large, non-symmetrical structural components with complex internal bracing, including engine mount brackets, turbine housings, and airframe structural pieces. High-strength, heat-resistant aluminum alloys such as A356 are commonly used and can be heat-treated to meet strict performance specifications. Producing near-net-shape parts with integrated features reduces the buy-to-fly ratio, a critical efficiency and cost metric in aviation.

Automotive and Commercial Vehicle

Sand casting is widely applied in heavy-duty and commercial vehicles for large, complex powertrain and chassis components. Applications include diesel engine blocks and cylinder heads with intricate cooling and oil galleries created using sand cores, as well as complex transmission cases and differential carriers. The rise of electric vehicles has increased demand for sand-cast custom automotive parts, such as motor housings and battery tray enclosures.

Heavy Machinery and Industrial Equipment

Construction, mining, and agricultural machinery rely on durable, high-integrity components produced by sand casting. This includes hydraulic valve bodies, pump housings, gearboxes, and structural frames for excavators and tractors. The ability to cast in wear-resistant Aluminum Bronze C95400 or high-strength steel for extreme loads is a key advantage.

Energy and Power Generation

Sand casting supports critical components in wind, hydro, and thermal power sectors. Common applications include pump and valve bodies for fluid control, turbine impellers, and housings for generators and gearboxes. Parts often require copper-based alloys for corrosion resistance or specialized steels for high-temperature performance, with integrity verified through extensive die castings inspection.

Marine and Shipbuilding

The marine industry benefits from sand casting for large, corrosion-resistant components such as propeller blades, stern frames, pump housings for ballast and bilge systems, and deck machinery. Corrosion-resistant materials like Leaded Bronze C83600 and other copper alloys are commonly used to ensure long-term performance in seawater environments.
