Foundry & Forging calculator

Sand Usage Calculator

Check the prepared sand supply for a production interval. Enter required sand, usable supply and your maximum planned loading percentage.

What this calculator does

  • Compare prepared sand demand with available supply and your maximum planned loading.

Formula used

  • Utilization = required sand ÷ available sand × 100
  • Gap to target = target loading − utilization
  • Demand at target = available sand × target loading ÷ 100
  • Physical shortage = max(required sand − available sand, 0)

Inputs explained

  • Required Prepared Sand: Mold and core requirements for the selected production interval.
  • Available Prepared Sand: Usable prepared sand available during that same interval.
  • Target Sand System Loading: Maximum planned usage percentage from the production schedule.

How to use the result

  • Best suited to molding schedule Check, prepared sand supply planning.
  • Circulating sand inventory is not automatically available throughput. This check does not approve reclaimed sand quality or binder demand.

Current U.S. benchmarks

  • The producer price index for steel mill products stands at 381.162 (BLS, Aug 2026), up 23.4% from a year earlier. Quotes priced off last quarter's material cost miss this move.
  • The U.S. has 3,569 primary metal manufacturing establishments employing about 354,911 workers (Census County Business Patterns, 2023).

Common questions

  • Can utilization exceed 100%? Yes, it signals a physical shortage. Increase released prepared supply or reduce the scheduled demand.
  • Should I use total sand system inventory? Only if that inventory is actually prepared and available during the chosen interval. Sand still in molds or awaiting reclamation is not immediately usable supply.
  • Does changing the target change sand consumption? No, the target changes the planning gap. The measured requirement and available supply determine utilization.
  • Can reclaimed sand be counted as available? Yes, after it meets the shop’s release criteria and becomes available for this interval. Recovery percentage alone does not establish mold suitability.
