Cast moulding

The Norton Cast moulding system utilises a Phenolic Ester chemical binder system, with a high level of sand reclamation. The extensive use of chromite and zircon refractory sands and mould coatings contribute to achieving our consistently high quality standards in cast moulding.

Our investment into cast moulding technology includes computer controlled binder additions with real time monitoring and calibration. This enables us to guarantee a consistent mould quality and excellent casting surface finish to meet the high standards set by our customers.

The cast molding process typically involves the following steps:

  • Pattern Creation: A pattern, which is a replica of the desired object, is created. The pattern can be made from various materials such as wood, plastic, or metal.
  • Mould Preparation: The mould is prepared by placing the pattern in a moulding material, such as sand, plaster, or refractory ceramic. The moulding material is packed around the pattern to create a cavity that matches the desired shape of the object.
  • Pattern Removal: Once the mould material has solidified, the pattern is removed from the mould, leaving a cavity in the shape of the object.
  • Pouring: The liquid or molten material, often referred to as the casting material, is poured into the mould cavity. The casting material can be steel alloys, nickel alloys, cobalt alloys, aluminium, iron, or bronze.
  • Solidification: The casting material is allowed to cool and solidify within the mould, taking the shape of the mould cavity.
  • Mould Removal: After the casting material has solidified, the mould is opened or broken to remove the newly formed object, which is now a solid replica of the original pattern.
