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.
- Tight Tolerances & High Prectsion
- Excellent Surface &Finish
- Complex Shapes Made Easy
- Aerospace-Grade Quality
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.
Investment Casting
- Tight tolerances & high precision
- Excellent surface finish
- Complex shapes & fine details
- Better dimensional accuracy
- Higher cost per part
Sand Casting
- Lower cost per part
- Ideal for large, simple parts
- Lower surface finish
- Looser tolerances
- More post-casting work
Metals We Cast
We cast in Steel, Iron, Aluminium, and Brass, each chosen to match your part’s strength, weight, and environment.
Steel
We cast in Steel, Iron, Aluminium, and Brass, each chosen to match your part’s strength, weight, and environment.
Iron
Durable & wear-resistant for defence & industrial applications
Aluminium
Lightweight with excellent strength-to- weight ratio.
Brass
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
Wax Pattern Creation
Built to match your part's exact geometry.
Ceramic Shell Building
Layered around the wax pattern for strength.
Wax Removal & Firing
The shell is hardened, ready for pouring.
Pouring & Cooling
Molten metal fills the cavity left behind.
Shell Removal & Finishing
The ceramic is broken away and the part is cleaned and inspected.
Quality Inspection
Every batch is inspected for dimensions and defects.
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.
What is lost wax casting used for?
It is used for complex, high-precision components that need an excellent surface finish, including aerospace, defence, and industrial valve parts.
How is this different from sand casting?
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.
Which industries rely on this process?
Aerospace, defence, automotive, and general precision engineering all rely on it for complex, high-precision parts.
What surface finish can I expect?
It produces one of the smoothest as-cast surface finishes of any casting process, often reducing or removing the need for secondary finishing.
How precise is the tolerance achievable?
It can hold tighter dimensional tolerances than sand or gravity die casting, making it ideal for complex, close-tolerance components.
What materials can be cast this way?
Steel, iron, aluminium, and brass are all commonly investment cast, chosen based on strength, weight, and the application's needs.
What is MGB Housing in a helicopter?
MGB stands for Main Gear Box, the housing supports the helicopter's main rotor gearbox and demands aerospace-grade precision casting.
