Lost Wax Process

  • Special Wax is injected into metal die to make wax patterns.
  • Wax patterns (replica of part) assembled into a cluster around a wax runner system.
  • The “Tree” of patterns then coated with layers of a refractory material.
  • Each layer being dried or chemically cured before the next layer is applied.
  • Assembly is heated to remove the wax & fired at high temperature to bond the mold.
  • The mould is heated and molten metal poured.
  • When cool, the mould material is removed.
  • Castings are removed from the runner system for secondary process and final finishing.
