Product Description

What is Steel Lost Wax Casting?

Steel lost wax casting is a casting process used to produce high-precision steel parts with fine surface finish and dimensional accuracy using a wax pattern. The process is widely used for the production of steel parts with intricate shapes and high dimensional tolerances in industries like aerospace, defense, and automotive.
The primary steps in steel lost wax casting include:
Wax pattern creation: A wax pattern is created that represents the final shape of the product.
Wax assembly: Several wax patterns are attached to a central hub called a sprue or gating system.
Coating: Wax patterns and gating system assembly is coated with a ceramic shell. The ceramic shell is allowed to dry and harden, repeating the steps until a thick coat accumulates.
Dewaxing: The ceramic shell with the wax pattern and gating system assembly is put into an oven to melt the wax out, leaving behind a ceramic shell with the shape of the wax.
Molten steel pouring: Molten steel is then poured into the ceramic shell.
Cooling and Solidification: The molten steel inside cools and solidifies inside the ceramic shell, taking the shape of the pattern.
Knockout: The ceramic shell is broken off, revealing the finished steel castings.
Finishing: Any excess material is removed, and the surface of the cast is finished and polished as needed.
Steel lost wax casting provides accurate and intricate components quickly with a low tolerance on wall thickness and multiple finishes. The process's flexibility makes it suitable for different types of steels like stainless steel, carbon steel, and other alloys. Steel lost wax casting is also ideal for producing complex shapes such as blades, pumps, and impellers.

Why is it Called Steel Lost Wax Casting?

Steel lost wax casting is called so because the process involves using wax to create a pattern or replica of the final product, which is then surrounded by a ceramic shell and filled with molten steel. Once the steel solidifies, the ceramic shell is removed, which causes the wax to be lost or melted away during the process.

The first part of the process involves creating a wax pattern, which is a replica of the final product. This wax pattern is used to create a mold in the ceramic shell, inside which the molten steel is poured. The ceramic shell is broken away, revealing the final steel casting or component.

The term "steel" is used in the name due to the fact that this process is primarily used for casting steel parts, although the process can also be used for other alloys as well. The term "lost wax" is used because the wax pattern is melted and lost during the process, leaving behind a cavity in the ceramic shell that is used to shape molten steel into the final product or component.

What is the Steel Lost Wax Casting Process?

The Steel Lost Wax Casting Process involves the following steps:
Creating the Wax Pattern: Wax patterns are created that represent the final shape of the product. This can be done by injecting molten wax into a metal mold or by hand sculpting the wax.
Assembling the Wax Pattern: Several wax patterns are attached to a central wax runner or gating system, which channels molten steel to the wax patterns.
Applying the Ceramic Material: The wax tree or assembly is then dipped into a ceramic slurry, which is allowed to dry and harden. This process is repeated several times until a thick layer of ceramic is build-up around the wax pattern.
Melting the Wax: The entire assembly is then heated in an oven to melt the wax out of the ceramic shell, leaving behind a hollow mold with the shape of the wax runner and wax patterns.
Preheating: The ceramic shell is preheated to ensure it can withstand the molten steel's temperature.
Pouring the Molten Steel: The preheated ceramic shell is filled with molten steel via the gating system.
Cooling and Solidification: The molten steel inside cools and solidifies inside the ceramic shell, taking on the shape of the wax pattern.
Knockout: After the steel has solidified and cooled, the ceramic shell is removed by various means and the castings are extracted from the mold.
Finishing: The steel casting is then cleaned, finished, and polished, as necessary, as per the final product requirements.
Steel Lost Wax Casting can produce steel components with complex geometries and fine surface finish. The process offers high dimensional accuracy with low tolerances and is perfect for small to medium production runs. Steel Lost Wax Casting is commonly used in the aerospace, automobile, and military industries to produce precision steel components.

What Materials can be Steel Lost Wax Casting?

Steel lost wax casting is primarily used for steel materials, but other metals and alloys can also be cast using this process. Some of the materials that can be used in steel lost wax casting include: Stainless steel: A popular material used in steel lost wax casting, known for its excellent corrosion resistance and high strength.
Carbon steel: It is a widely used material in the automotive and construction industries due to its high strength and durability.
Low-alloy steel: Several low-alloy steels containing chromium, molybdenum, and other elements can be used to cast steel products with unique performance properties.
Tool steel: This material offers high hardness, toughness, and wear resistance which makes it suitable for the fabrication of tool components.
Copper alloys: These materials can be used to cast parts that require excellent electrical conductivity or high thermal conductivity such as heat exchangers, electrical contacts, and electrical connectors.
The steel lost wax casting process can be used to cast other materials besides steel, but it is most commonly used with steel-based alloys. The choice of the material used will depend on the component's final desired properties, such as strength, corrosion resistance, and hardness. The selection of the metal or alloy to use during the casting process also depends on the composition and thickness of the wax pattern and the size of the component.
