When trying to decide whether to use investment casting or sand casting to produce parts, consider the following:
Investment Casting
- Can produce complex parts, even with very thin walls.
- Offers the accuracy to achieve precise specifications.
- Delivers high-quality surface finishes with little or no machining and finishing.
- Can utilize duplex alloys and both ferrous and non-ferrous metals.
- Is an economical option over long and repeat runs.
Sand Casting
- Can be lower cost in some situations, like shorter runs.
- Can produce very large castings.
- Also accommodates ferrous and non-ferrous alloys.
- May be a good option when top quality and precision are not required.
