Sand Casting Process

The sand casting process is used typically for larger parts and for small quantities of parts. Sand casting is capable of making fairly complex shapes using relatively inexpensive wood patterns.  Sand, containing a natural or synthetic binder, is packed around a wood pattern, the sand is then tamped down to provide the two-part mold with adequate strength. The pattern is then removed, leaving a negative form in the mold. 

Cavities can be produced in the sand casting by inlaying one or more cores in the mold. The two halves of the mold are clamped together ready for casting.

Our sand and face coat systems have been optimized to give superior surfaces for corrosion resistant alloys. 

A wide range of cobalt alloys, nickel alloys and stainless steel alloys can be poured in our modern Sand Foundry.  All castings produced can be finished to print in our Machine Shop.

Sand Casting Capacities

IS THE SAND CASTING PROCESS FOR YOU?

Sand casting is best for large components with thick cross sections. This process is capable of making fairly complex shapes using relatively inexpensive wood patterns. Our sand and face coat systems have been optimised to give superior surfaces for corrosion resistant alloys. If your component meets one or more of the following basic criteria, sand casting could be the correct process selection.

  • Low to medium volume requirements
  • Simple to medium part complexity
  • Component has thick cross section

Materials

  • Stellite Alloys
  • Tribaloy Alloys
  • Deloro Alloys
  • Nistelle Alloys
  • Stainless Steel Alloys
  • Other alloys available on request
