Die/Tooling Construction/Manufacturing: A negative replica of the part or component is prepared in form of Metallic Die, for creation of wax pattern, which matches the configuration and finish of the final metal part. Depending on production quantities, size, shape & complexity, these dies may be of single cavity or multiple cavities.

Wax Pattern Injection & Assembly: Disposable Wax Patterns are produced by injecting Wax in the Dies. These Wax Patterns are positive models of the part intended for casting and reflect the precise geometry of the finished parts. Multiple nos. of Wax Patterns are made and connected & assembled by ‘gates’ to Wax sprue to form a tree or cluster.

Ceramic Coating (Ceramic Investment) : Successive coats of ceramic slurry and refractory sand, fused silica are applied on assembled cluster/tree with intermediate drying time to form a self-supporting ‘Shell’ or called ‘Mold’.

De-Waxing & Curing: De-waxing is the next step. The ‘Invested’ Wax in the properly dried shells are melted out by applying heat source. The ‘hollow’ shells are formed having cavities inside. These ‘hollow’ shells or ceramic mould are then fired in high temperature baking furnace to cure the refractory material and to withstand the molten metal during pouring from the melting unit.

Melting & Casting: The specified molten metal alloyed in induction melting furnace is then poured in the pre-heated & hot-baked hollow shells (moulds) ensuring complete filling of the entire shell cavity.

Shell Release & Fettling/Grinding: Upon cooling, the ceramic shells are removed by usual knocking out operations by mechanical vibration and chemical cleaning. Parts are separated from the metallic sprues resulting Precision Castings after usual operations of gate grinding, cleaning and further operation like heat treatment, surface treatment etc.

Final Inspection: Finished products of casting are carefully inspected for compliance with client’s drawings and specifications and thorough visual & dimensional inspection are carried out to maintain the integrity of the required component.
