Lost Wax Casting Services
Lost wax casting services from Kormax deliver intricate, high-precision metal components through a qualified global foundry network. We manage the entire process on your behalf, giving you one accountable partner from drawing review through repeat production. With structured engineering input, strict quality coordination, and trusted international supply, we help you reduce risk while achieving consistent casting outcomes.
What Is Lost Wax Casting?
Lost wax casting is also known as lost wax investment casting or precision casting. It produces complex metal components with excellent surface finish, strong dimensional control, and near-net shape, reducing the need for secondary machining.
You can learn more about the broader process on our investment casting page.
Kormax evaluates your application and recommends the right casting process and alloy through our global foundry network. We coordinate production end to end, acting as your single point of contact across our foundry network.
Benefits of Lost Wax Investment Casting

Complex geometry and fine detail
Ideal for components with internal cavities, thin sections, and intricate profiles that would be difficult or costly to machine from billet.

Excellent as-cast surface finish
Produces smooth surfaces around 125 Ra, reducing post-cast finishing requirements and supporting tighter dimensional control.

Near net shape, reduced machining and waste
Precision molds mean less excess material, lower machining time, and improved material efficiency.

Part consolidation
Multiple fabricated components can often be combined into a single casting, reducing assembly steps and potential failure points.

Repeatability for production runs
Tooling-driven production delivers consistent quality across prototype batches and at scaled manufacturing volumes.

Broad alloy compatibility
Suitable for a wide range of materials, including stainless steel casting, steel casting, iron casting, and nickel casting grades.

Suitable for thin walls and precision features
Well-suited to lightweight components and designs requiring fine detail without compromising structural integrity.

The Lost Wax Casting Process
Our lost wax investment casting process follows a structured, quality-controlled sequence:

Design review and optimization
We assess your drawings using design for manufacturing principles to improve castability, control tolerances, and reduce total cost.

Tooling and wax pattern production
Precision tooling is created and used to form wax replicas of your component.

Tree assembly and ceramic shell building
Wax patterns are assembled and repeatedly coated in ceramic slurry to build a durable mold.

Dewaxing and firing
The wax is removed, leaving a cavity. The ceramic shell is fired to achieve the required strength.

Metal pouring
Molten alloy is poured into the mold under controlled conditions.

Shell removal and finishing
The ceramic shell is broken away. Components are separated, cleaned, and finished as specified.
Throughout production, Kormax coordinates inspection, traceability, and communication across our network of lost wax casting foundries, reducing complexity for your procurement and engineering teams.
Alloys Available for Lost Wax Casting
We support a broad range of materials suited to structural, corrosive, and high-temperature environments.
| Capability | Specification |
| Stainless steel casting alloys | Common grades include 304, 316, 17-4 PH, and selected duplex options. These are widely used where corrosion resistance and mechanical strength are critical. |
| Steel casting alloys | Carbon steels, low-alloy steels, and manganese steels are suited for structural and wear applications. |
| Nickel casting alloys | Selected nickel-based alloys are suitable for elevated temperature and corrosive service conditions. |
If you’re unsure which material best suits your application, our team will guide alloy selection based on load case, environment, and compliance requirements.
