Investment Casting

Overview

Investment casting — also known as lost-wax casting — is used to make complex-shaped components that need tight tolerances and a fine surface finish. Compared with other casting processes it delivers better accuracy, thinner walls and more intricate detail, reducing the machining a part needs afterwards.

At Godani we cast ferrous materials such as stainless steel, mild steel and the EN series, and non-ferrous materials such as brass and bronze, to the grade on your drawing. Our castings serve Indian Railways, oil & gas, medical implants, defence, automotive, marine, valves, bath fittings and general engineering.

Castings from a few grams up to 120 kg
Stainless, carbon, alloy & EN series steels
Brass, bronze and copper alloys
Zinc pressure die casting also available

In-house tooling, testing and machining

How it's made

From wax to world in seven steps.

Every Godani component follows the same controlled route through our plant — so the thousandth part matches the first.

  1. 01

    Tooling & wax pattern

    In-house aluminium dies are built from your drawing, then injected with wax to form an exact replica of the part.

  2. 02

    Cleaning & repairing

    Each wax pattern is inspected, cleaned of flash and parting lines, and any surface defects are repaired by hand before assembly.

  3. 03

    Tree assembly

    Wax patterns are gated onto a central wax riser, building a ‘tree’ that casts many parts in a single pour.

  4. 04

    Ceramic shell

    The tree is dipped in ceramic slurry and stuccoed, layer after layer, until the shell reaches the required strength.

  5. 05

    Dewax & pour

    Wax is melted out and the pre-heated shell is filled with molten metal of the specified grade.

  6. 06

    Knock-out & finish

    The shell is broken away, parts are cut from the tree, fettled, heat treated and shot blasted.

  7. 07

    Machine & inspect

    CNC and VMC machining brings critical features to tolerance before every part is tested and released.
