Because sand tooling (patterns and core boxes) costs a fraction of permanent metal molds, sand casting is the fastest, cheapest way to validate a design at real scale — especially for larger or more complex geometries.

The trick is knowing when to stay on sand and when to move to a metal mold as volumes grow. The crossover depends on part size, alloy and how much machining you planned anyway.

Key Points

  • Cost sweet spot: for annual volumes under a few thousand pieces, or for parts above ~30 kg, sand casting often wins on total landed cost.
  • Speed: a wood or resin pattern can be cut in 7–15 days; first samples in about a week — ideal for pre-production validation.
  • Design freedom: sand cores allow internal passages and undercuts that are hard or impossible in permanent molds.
  • Our hybrid approach: validate in sand, then transfer to gravity or low-pressure tooling once the design and volumes are confirmed — one supplier, two routes.
