Precision Casting Unveiled: The Art and Science Behind Our Process

Embark on a journey through the intricate stages of precision casting at Fourus Techno Cast. From the meticulous die/tooling design to the final inspection, each step is a testament to our commitment to innovation, quality, and the seamless transformation of raw materials into precision-crafted components.

Our Precision Casting Process

At Fourus Techno Cast, our precision casting process is a meticulous journey that transforms raw materials into high-quality precision components. Here’s an overview of each crucial step in our process:

1
1

Die/Tooling Design

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.

2

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 are assembled by ‘ingates’ to Wax sprue to form a tree or cluster.
3
3

Ceramic Coating (shell moulding)

Successive coats of ceramic slurry and refractory sand, fused silica is applied on assembled cluster/tree with intermediate drying time to form a self-supporting ‘Shell’ or called ‘Mould’.

De-Waxing & Curing

De-waxing is the next step. The ‘Invested’ Wax in the properly dried shells are melted out by 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.

5

Melting & Casting

The specified metal melted in induction melting furnace is then poured in the pre-heated & hot-baked hollow shells (moulds) ensuring complete filling of the entire shell cavity.
6
6

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 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.
