Certifications

Processing

Investment casting stands as a beacon of innovation and precision, acclaimed for crafting high-precision metal components. With its unmatched accuracy and quality, this sophisticated process caters to sectors like aerospace, automotive, and medical, among others. Dive into the detailed steps of this intricate process and uncover the marvel of how these exceptional components are brought to life with precision and excellence.

1. Wax Pattern Creation

Our journey begins with the artful creation of wax patterns. Expert artisans meticulously inject superior-grade wax into finely crafted aluminum molds, mirroring the exact dimensions and contours of the final product. This wax model forms the blueprint and foundation for the entire casting process, underscoring the significance of precision at this stage. The finesse of these patterns directly influences the excellence of the final metal component.

2. Assembly

In the assembly phase, each wax pattern is delicately attached to a central wax sprue, forming what's known as a pattern assembly or wax tree. This central sprue is pivotal, serving as the conduit for molten metal to flow into the intricate cavities of the wax patterns. Precision and careful attention ensure the correct alignment and secure attachment of patterns, setting the stage for flawless casting.

3. Shell Building

The transformative shell-building stage sees the pattern assembly immersed in high-quality ceramic slurry. Layer upon layer of refractory material is added, ensuring each is fully dried before the next. This meticulous process results in a robust ceramic shell, enveloping the wax patterns and providing essential structure and protection. This step prepares the assembly for the rigors of the investment casting journey.

4. Dewaxing

Dewaxing marks a pivotal phase where the wax within the ceramic shell is melted away in a high-temperature furnace. Known as "lost-wax casting," this step leaves behind a hollow ceramic mold, with cavities that perfectly mirror the original wax patterns. This precise mold is now ready to embrace the molten metal that will take its shape, leading to the creation of the desired component.

5. Burnout/Preheating

In the burnout stage, the ceramic mold is subjected to extremely high temperatures, ensuring complete wax removal and hardening the mold. Preheating is crucial, facilitating smooth metal flow and ensuring uniform cavity filling, thereby minimizing defects. This preparation leaves the mold in pristine condition, ready to receive the molten metal and translate the vision into reality.

6. Pouring

The pouring step is the heart of investment casting. Carefully selected molten metal, aligned with specific grade requirements, is poured into the preheated mold. It swiftly fills every contour of the mold, embodying the exact shape of the original wax pattern. The process is precisely controlled, ensuring the resultant metal component is a testament to quality and craftsmanship.

7. Shell Removal

Once the metal solidifies, the ceramic shell is carefully removed to reveal the meticulously crafted metal component inside. Vibratory methods delicately break away the shell, unveiling the masterpiece within. This step requires precision to preserve the integrity of the final product, which is indeed a work of art.

8. Cut-off

Once the shell has been meticulously removed, each individual metal casting is carefully separated from the central sprue with specialized saws or precision cutting tools. This intricate separation process is executed with exceptional precision to ensure a clean and accurate cut, thus preparing the metal component for the next stages of processing with utmost readiness.

9. Finishing

The crowning step in the investment casting journey is the execution of any essential finishing operations tailored to the component's specific requirements. Depending on the end-use application, a variety of sophisticated finishing techniques may be employed. For example, heat treatment may be essential to fortify the metal's mechanical properties, boosting its strength and hardness. CNC machining offers the capability to achieve incredibly precise dimensions and tolerances. Furthermore, shot blasting is often chosen to meticulously cleanse the surface, ensuring a refined, smooth finish. Polishing then adds the final touch, bestowing the component with a lustrous and captivating surface appearance.

Investment casting stands as a marvel of modern manufacturing, seamlessly blending skill, precision, and cutting-edge techniques to craft high-quality metal components. These components consistently meet even the most stringent standards across a diverse array of industries, showcasing the process's capability to deliver excellence.

4. Q: What are the advantages of stainless steel casting?
A: Stainless steel casting allows for producing stainless steel components with complex shapes, less or no machining, no quantity limitations, and so no.

5. Q: What type of tooling is required for stainless steel casting?

A: A split aluminum tool or mold is used to create a wax pattern, which is then coated with layers of stucco and ceramic material. Before pouring the alloy, wax will be first melted away, which is where the term "lost wax casting" originated. In other processes (forging, stamping, die casting), tooling is quite much more expensive.
