Stainless Steel Investment Castings
Stainless Steel investment casting, also known as the lost-wax casting process, is a specialized method used to create complex and high-quality Stainless Steel components. It is particularly advantageous for producing parts with intricate details, tight tolerances, and excellent surface finishes. This casting process is widely employed in various industries, including aerospace, automotive, medical, and more, where precision and durability are critical.
- Easily convert multiple parts into single assemblies
- Intricate, near-net shape parts without secondary machining
- Surface texture of 125 rms or better
- Thin walls for weight reduction opportunities
- Highly complex dimensional geometry
- Tolerances within +/- .005 inches per linear inch
From concept to completion, Conex can help you meet the form, fit, and function of your design.

The Stainless Steel investment casting process involves the following steps:
- Creating the Wax Pattern: The process begins with the creation of a wax pattern of the desired Stainless Steel component. This can be done by injecting molten wax into a mould that is formed by using the original pattern or a 3D model of the part.
- Assembly of the Wax Patterns: Once the individual wax patterns are created, they are assembled together onto a wax tree, also known as a sprue. Several wax patterns may be combined on a single tree to optimize the casting process.
- Investment Moulding: The wax tree with the assembled patterns is coated with a refractory ceramic material, known as the investment. This investment material hardens around the wax patterns, forming a ceramic shell. The investment shell serves as the mould for the final Stainless Steel casting.
- De-Waxing: The investment shell, now containing the hollow cavities left by the melted wax, is heated in an autoclave or furnace. The high temperature melts and vaporizes the wax, leaving behind a cavity with the exact shape of the original pattern within the hardened investment mould. This step is called “de-waxing” or “dewaxing.”
- Preheating: Once the wax has been removed, the investment mould is preheated to prepare it for the molten Stainless Steel.
- Casting: Molten Stainless Steel is poured into the preheated investment mould under controlled conditions. The high temperature allows the Stainless Steel to fill the cavity and take the shape of the original wax pattern.
- Solidification and Cooling: The molten stainless steel solidifies within the investment mould. After a suitable cooling time, the mould is broken or removed to reveal the Stainless Steel casting.
- Finishing: The Stainless Steel casting may undergo additional finishing processes such as removal of the sprue, grinding, polishing, and machining to achieve the desired final appearance and dimensions.
Stainless Steel investment casting offers several advantages, including the ability to produce complex shapes and thin-walled parts with high accuracy and surface finish. It also allows for the use of various Stainless Steel alloys, each offering specific properties such as corrosion resistance, high strength, and heat resistance.
