Sand Casting

Why Choose Sand Casting?

Sand casting is the most commonly used casting process because of the cost effectiveness of the process and the availability of raw materials. Sand casting is a process where the molten metal is poured into a mould made of sand. It is best suited to low-volume or complex non-ferrous castings or large ferrous castings.

WELD2CAST Engineering is able to produce complex sand-casting moulds by hand using Greensand for smaller quantities and Resin or Petrol-Bonded Techniques using a semi-automated or automatic Horizontal Moulding Machine (DISAMATIC) process for larger quantities.


WELD2CAST’s Sand Casting Benefits Include:

  1. Low tooling costs and fast set-up compared to other castings techniques.
  2. Complex and intricate castings can be achieved with multiple internal cores.
  3. Up to 75% of the sand used in the process is possible to reclaimed.
  4. High production efficiency (average of 200-300 units per hour).
  5. More flexible castings methods depending on quantities.
  6. Practically possible to cast any material, including those with a high melting point.
