Process

A CAD designer creates 3D model of the tool from CAD data. Die or tool for imparting a desired shape, form, or finish to a material.

The tool is used to create a wax pattern, using thermos setting wax injection moulding machines.

The resulting wax ‘pattern’ is attached to a ‘tree’ (essentially a central wax form).

The Wax Assembly is coated in liquid ceramic slurry (silica sol).

In order to minimize ceramic shell cracking, the dewaxing autoclave must quickly transfer thermal energy into the ceramic shell and melt the surface wax so that it can be absorbed into the primary ceramic interface layer.

The shell is filled with molten metal (a range of ferrous metals like cardon steels, alloy steels, nickel based super alloys, super duplex etc.)

Once cooled, the ceramic shell is mechanically removed to reveal the cast metal mould beneath.

This heat treatment process is used to improve the mechanical properties of steels, fatigue life, wear resistance and provide anti corrosion properties.

Metal Castings are removed from the assembly by various cutting techniques. Once removed, the individual cast parts are worked individually for fettling & subsequent process.

All finished items will be packed as necessary for safe transportation, i.e. in Wooden Case, cardboard carton or Jiffy Bag dependent on weight, value and method of transportation. Where necessary suitable protective wrapping paper to protect against damp shall be used.
