The Step-by-Step Manufacturing Process

• Tooling & Pattern Design: We machine highly accurate aluminum dies based on your exact CAD files to serve as the master mold for your custom metal parts.
• Wax Injection: Liquid wax is injected into the tooling under high pressure to form a flawless, exact replica of the final component.
• Shell Building (Ceramic Slurry): The wax patterns are attached to a central sprue and repeatedly dipped into a ceramic slurry and fine sand to build a rigid, heat-resistant shell.
• Dewaxing & Firing: The coated tree is flash-heated to melt out the wax and then fired in a high-temperature kiln to cure and strengthen the ceramic mold.
• Pouring (Gravity/Vacuum): Molten metal is poured directly into the hollow shell. Depending on the alloy and geometry, we utilize either gravity or vacuum pouring to ensure the precision cast components are dense and defect-free.
• Knockout & Finishing: Once the metal solidifies, the ceramic shell is vibrated off and broken away. The individual parts are cut from the tree, gates are ground down, and the required surface finishing is applied.
• Inspection & Shipping: Every production run undergoes rigorous dimensional checks and non-destructive testing before being securely packaged and shipped directly to your dock.

Frequently Asked Questions about Precision Casting

What is the minimum wall thickness you can cast?

Achieving thin walls is one of the main benefits of the lost-wax process, but the exact limit depends heavily on the specific alloy and the part’s geometry. At Precisionvast, we don’t just guess; we utilize CAE (Computer-Aided Engineering) simulation to analyze fluid flow and solidification before we pour a single drop of metal. This allows us to determine the thinnest possible wall that maintains structural integrity for your specific precision cast components. Send us your engineering blueprints, and our team will confirm the feasibility for your design.

How does investment casting compare to die casting or sand casting?

Investment casting (lost-wax) sits in a sweet spot for high-performance applications. Compared to sand casting, it offers significantly better surface finishes and much tighter dimensional tolerances, reducing the need for extensive secondary machining. Unlike die casting, which is often limited to non-ferrous metals like zinc or aluminum, our process handles a massive range of materials, including high-temperature superalloys and stainless steel. If you are curious about how the workflow differs, reviewing the basic steps in the steel casting process can highlight why investment casting is preferred for complex, near-net-shape parts.

What is the typical lead time for tooling and first articles?

Speed matters in manufacturing. While exact timelines vary based on the complexity of the mold design, we offer rapid prototyping via SLA printing to accelerate product development. This helps you validate designs faster before committing to hard tooling. For production runs, our streamlined “one-stop” manufacturing approach—from wax injection to final CMM inspection—keeps lead times competitive.

Investment Casting Glossary & Key Terms

• Near-Net-Shape Manufacturing: A production technique where the initial casting is incredibly close to the final required dimensions, drastically reducing the need for secondary CNC machining services.
• Lost Wax Casting: Also known as investment casting, a process where a disposable wax pattern is created, coated in a ceramic slurry to form a mold, and then melted out (“lost”) before molten metal is poured in.
• RMS (Root Mean Square): A standard measurement of surface roughness. Our ability to achieve 125 to 63 RMS right out of the mold means fewer secondary polishing costs for your custom metal parts.
• DFM (Design for Manufacturing): The process of proactively adjusting a CAD design to make it easier, cheaper, and faster to manufacture via the investment casting process.
