Investment Casting or Sand Casting

Sep 6, 2022

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.
