Hard Sand Moulding

Hard Sand moulding  is characterised by using sand as the mould material.  In addition to sand often a bonding agent such as resin is coupled with a hardener and mixed with the sand. This allows the sand grains to essentially be glued into place as they are moulded around a pattern of the shape that you want.  The resultant hardened sand mould is what the molten metal is then poured into.

Hard Sand Moulding Advantages

The Hard Sand moulding process can have specific advantages over other manufacturing processes, which often lead to major cost savings, not only in the part price itself but also in the overall cost of production. Some of the benefits are in the processes flexibility:

  • Variety of metals able to be cast – ability to use both ferrous or non-ferrous metals.
  • Automated or hand crafted for accuracy – Mould replicates the component with high level of accuracy and consistency.
  • Jobbing or low volume production – ability to produce from 1 to 1000 units per run.
  • Complex shapes – undercuts and hollow centres can be formed and the process is capable of producing very large pieces.
  • Minimal wastage – Scrap and moulds can be and are often recycled
