Selecting the right metal casting process depends on your part geometry, material requirements, tolerances, and production goals. We support a wide range of casting technologies to manufacture custom metal components across multiple industries.
Die Casting
- Cold Chamber Die Casting: Uses high-pressure injection for aluminum alloys and other higher melting point metals, making it ideal for scalable production.
- Hot Chamber Die Casting: A highly automated process designed for rapid cycle times and lower melting point alloys.
- Multi-Slide Die Casting: Produces complex near-net-shape components that help reduce secondary machining operations.
- Overmolding Processes: Combines cast metal components with additional materials to improve part functionality and performance.
Investment Casting
- Precision Investment Casting: Also known as lost-wax casting, this process produces highly intricate components with tight tolerances and excellent surface finishes.
Sand Casting
- Traditional Sand Casting: Utilizes green sand or Petrobond molds to create cost-effective large and heavy metal components.

Frequently Asked Questions
What Do You Mean by Metal Casting?
Metal casting is a foundational manufacturing process where molten metal is poured into a precise mold cavity. The material then cools and solidifies into complex and solid shapes.
The process requires five key steps including pattern making, mold making, melting, pouring, and final extraction. This method allows engineers to create highly detailed parts that would be too difficult or expensive to machine from a solid block.
Is CNC Machining Better Than Metal Casting?
CNC machining is highly precise, but it’s often more expensive and slower at massive scale due to material waste. Metal casting is highly efficient and cost-effective for medium to large volume production runs of complex geometries.
Machining removes material from a solid block, requiring more time per unit during large runs. Casting forms the part directly, and manufacturers typically use CNC machining as a secondary operation to achieve final tight tolerances. This combined approach delivers both scalability and precision for industrial buyers.
What Is the Easiest Metal to Cast?
Aluminum is highly favored for industrial and high-volume production runs. Alloys like A380 and A383 feature a lower melting point and superior resistance to hot cracking.
These materials flow efficiently into complex molds, making them exceptionally castable for industrial structural parts and housings. This reliable flow rate helps manufacturers maintain consistent mechanical properties across massive production runs.
