Many parts can be made utilizing multiple casting processes, including both investment casting and sand casting. Consider these characteristics of each process when deciding which is best for a specific application:

Investment Casting

• Investment casting can achieve very thin walled parts with complex shapes.
• Very accurate, with precise dimensional casting – near-net-shape.
• Excellent surface finishes and precise details save machining and finishing.
• Ferrous and nonferrous metals, as well as duplex alloys, can be used.
• Investment casting can be quite economical over repeat runs.

Sand Casting

• Sand casting can be lower cost particularly in shorter runs.
• It can accommodate large castings.
• Sand casting can also utilize both ferrous and non-ferrous metals.
• The cost for post-casting tooling can be lower.

A trade-off for the sometimes lower cost of sand casting is overall lower quality, less accuracy and rougher surface finishes. The right choice depends on your specific needs.
