Metal Casting Capabilities
We offer diverse casting solutions tailored to your volume, material, and tolerance requirements.
Pressure Die Casting
Molten metal is forced into a steel mold under high pressure. Used for validated pilot or repeat runs when tooling economics, alloy choice, and tolerance assumptions fit the project.
- • Aluminum (A380, A356)
- • Zinc (Zamak 3, 5)
- • Magnesium (AZ91D)
- • Thin walls capable
Investment Casting
Also known as "Lost Wax" casting. Uses wax patterns (often 3D printed for low volumes) to create ceramic molds. Perfect for complex steel parts.
- • Stainless Steel (304, 316)
- • Carbon Steel
- • Brass & Bronze
- • Complex internal channels

Tooling route and unit cost depend on geometry, alloy, batch assumptions, and inspection scope.
Superior surface finish for steel.
Lowest tooling cost for big parts.
Material Options
Aluminum
Lightweight, good strength-to-weight. Commonly die cast (A380) for housings and brackets.
Zinc
High density, easy to plate. Excellent for small, detailed decorative parts.
Steel & Stainless
Investment cast for superior strength and corrosion resistance.
Metal Casting FAQ
How is batch size confirmed?
Batch size depends on casting route, material, tooling economics, finishing, and inspection scope. We confirm the practical quantity range during RFQ.
Why choose casting over CNC machining?
Casting is superior for complex internal geometries (undercuts) that CNC cannot reach. It also reduces material waste and cost for medium volumes (50+ parts) compared to machining from solid blocks.
Can you hold tight tolerances?
Casting alone has looser tolerances than CNC. However, we combine processes: we cast the near-net shape and then CNC machine critical features (holes, flat surfaces) to achieve high precision.
