MAHATI

Investment Casting Manufacturer — Aerospace-Grade Precision

We produce complex, high-precision metal parts with excellent surface finish in Steel, Iron, Aluminium and Brass, including aerospace-grade MGB Housing components used in helicopters.

What Is Investment Casting?

Also known as lost wax casting, it works by coating a wax pattern in a ceramic shell, melting the wax out, and pouring molten metal into the cavity left behind. The result is a part with a much finer surface finish and tighter tolerances than sand or gravity die casting can typically achieve, which is exactly why investment casting is chosen for complex, high-precision components.

Corrosion-resistant and ideal for precision components.

What Investment Casting Brings to Your Parts

When a part is complex, thin-walled or needs a fine finish, the lost wax process does the heavy lifting.

Benefit What It Means for You Why It Matters
Tight tolerances Parts come out very close to the drawing Less machining and fewer rejected pieces
Excellent surface finish A smooth surface straight from the shell Little or no extra finishing on most features
Complex, detailed shapes Thin sections, fine details and internal features Designs that are hard or impossible with sand casting
Near-net-shape parts Casting is already close to the final form Saves material, machining time and cost
Design freedom Fewer limits on undercuts and contours Combine several parts into one casting
Wide metal choice Steel, iron, aluminium and brass Pick the metal for strength, weight or corrosion needs
Repeatable quality Each wax pattern and shell follows the same process Consistent parts from batch to batch
How We Work

Our Process

1

Wax Pattern Creation

Built to match your part's exact geometry.

2

Ceramic Shell Building

Layered around the wax pattern for strength.

3

Wax Removal & Firing

The shell is hardened, ready for pouring.

4

Pouring & Cooling

Molten metal fills the cavity left behind.

5

Shell Removal & Finishing

The ceramic is broken away and the part is cleaned and inspected.

6

Quality Inspection

Every batch is inspected for dimensions and defects.

7

Dispatch

Approved parts are packed securely and shipped on time.

Precision Only Counts If It's Proven

Investment castings are often used where there is no room for error, so every stage is checked and documented.

Frequently Asked Questions

What is investment casting process?

Also called lost wax casting: a wax pattern is coated in a ceramic shell, the wax is melted out, and molten metal is poured into the resulting cavity for a highly precise, fine-finish part.

It is used for complex, high-precision components that need an excellent surface finish, including aerospace, defence, and industrial valve parts.

This process achieves tighter tolerances and a much finer surface finish, suited to complex geometries. Sand casting suits larger, simpler parts at a lower cost.

Aerospace, defence, automotive, and general precision engineering all rely on it for complex, high-precision parts.

It produces one of the smoothest as-cast surface finishes of any casting process, often reducing or removing the need for secondary finishing.

It can hold tighter dimensional tolerances than sand or gravity die casting, making it ideal for complex, close-tolerance components.

Steel, iron, aluminium, and brass are all commonly investment cast, chosen based on strength, weight, and the application's needs.

MGB stands for Main Gear Box, the housing supports the helicopter's main rotor gearbox and demands aerospace-grade precision casting.
