Investment Casting Process

our ‘investment casting process’ is meticulously engineered to produce highly precise and complex components.We specialize in transforming various alloys into intricately detailed parts with outstanding accuracy and surface finish, making us a leader in the investment casting industry.

Precision Casting Process

At Precisionvast, we leverage the centuries-old technology of investment casting, renowned for producing high-precision parts with minimal surface defects. Our process involves creating a wax model, encasing it in a ceramic shell, melting the wax to form a cavity, and then pouring molten metal into this cavity. Once the metal solidifies, the ceramic shell is removed, revealing a finished part requiring minimal post-processing. In our foundry, we utilize China’s most advanced technology for investment casting to produce top-tier castings in various sizes and shapes. Capable of working with a full range of metal alloys, we customize castings to your material specifications, even accommodating combinations of materials. To ensure the highest quality, each investment casting process undergoes rigorous quality control.

Investment casting process: step-by-step guide

01/

Pattern Assembly

Pattern Assembly

The first step in the precision casting process is to make a wax mold from a model, usually using a no-cylinder wax press to inject the wax into a metal mold. This initial step lays the foundation for detailed and precise casting.

02/

Wax Injection

Wax Injection

The wax trimming stage consists of accurately injecting molten wax into the prepared mold to form a detailed wax pattern, removing the mold fit lines and fly-aways from the top of the wax mold, which is critical for subsequent shell fabrication.

03/

Shell Building

Shell Building

In shell building, layers of ceramic material are applied over the wax patterns to create a strong, heat-resistant shell, crucial for holding the molten metal.

04/

Dewax Operation

Dewax Operation

The dewax operation involves melting out the wax from the ceramic shell, leaving a hollow cavity for metal casting.

05/

Dewaxing kettle

Dewaxing kettle

The dewaxing kettle is used to carefully remove the wax from the shells, ensuring the integrity of the hollow mold for casting

06/

casting

Casting

During casting, molten metal is poured into the hollow ceramic shells, accurately forming the desired metal parts.

07/

Shell Removing

Shell Removing

Once the metal solidifies, the ceramic shell is removed, revealing the raw cast metal component.

08/

Shot Blasting 

Shot Blasting

Shot blasting is employed to clean and smooth the surface of the cast metal, enhancing its appearance and texture.

09/

Shot Blasting

Grinding off Inlet

Grinding off the inlet involves removing the metal inlets and sprues, refining the final shape of the casting.

10/

Inspection

Inspection

For non-conforming castings, each casting is carefully welded and repaired to ensure compliance with specified dimensions and standards.

11/

pickling

Pickling

The pickling process involves treating the casting with a solution to remove impurities and enhance corrosion resistance.

12/

Polish

Polish

Polishing is carried out to achieve a smooth and shiny surface finish on the cast parts.

The CMM step involves precise dimensional and geometric measurement of the components for quality control.

Advantages of Investment casting process

At Precisionvast, we recognize the manifold advantages of the investment casting process, making it a preferred choice in our manufacturing operations.

Our investment casting process excels in producing parts with intricate details and high precision. This method allows us to create complex geometries, undercuts, and intricate shapes with outstanding dimensional accuracy, minimizing the need for secondary processing.

Parts produced through investment casting have a smoother surface finish compared to other casting methods. This superior finish reduces the need for additional surface treatments or fine machining, saving costs and production time.

We work with a wide array of metals and alloys, including steel, stainless steel, aluminum alloys, and bronze. This versatility ensures the selection of the most suitable material for specific properties like heat resistance, strength, or corrosion resistance.

 Investment casting is particularly cost-effective for small to medium production runs, involving fewer steps and less waste compared to other methods. While initial mold costs can be high, they are often offset by lower per-unit costs during production runs.

Known for producing near-net-shape parts, our investment casting process significantly reduces the need for additional machining or finishing, especially beneficial for parts with complex geometries or made from hard-to-machine materials.

Our investment casting process stands out as a versatile and efficient manufacturing technique, offering detailed, precise parts and a broad range of material choices, making it a viable option for various manufacturing scenarios.
