Precision Investment Casting Services | High Tolerance Alloys & Custom Solutions

What is Precision Investment Casting?

Precision investment casting, also known as the lost-wax casting process, is an advanced manufacturing technique used to create near-net-shape metal components with exceptional accuracy and smooth surface finishes. By injecting molten metal—such as stainless steel, titanium, or superalloys—into a disposable ceramic shell created from a wax pattern, manufacturers can achieve complex internal cavities and tight dimensional tolerances. This process significantly reduces material waste and minimizes the need for expensive secondary CNC machining.

Our 14-Step Precision Investment Casting Process

Quality isn’t an accident; it’s a sequence of deliberate, controlled actions. At our foundry, we execute a rigorous 14-step workflow for every project, ensuring that your precision investment casting components meet exact specifications from the core out. We handle the entire lifecycle in-house, from the initial wax model to the final CMM inspection.

Phase 1: Pattern & Shell Preparation

Everything starts with the mold. We begin by injecting wax into a metal die to create a precise replica of your part.

• Pattern Assembly: We mount multiple wax patterns onto a central sprue to create a “tree.”
• Shell Building: The wax tree is dipped in ceramic slurry and sand to build a hard shell.
• Design Validation: For complex geometries, we often employ rapid prototype investment casting techniques at this stage to verify the design before committing to mass production.

Phase 2: Dewaxing & Metal Pouring

Once the ceramic shell dries, we move to the critical “lost wax” phase.

• Dewax Operation: The shell is heated in a Dewaxing Kettle, melting the wax out to leave a perfectly hollow cavity.
• Casting: Molten metal—whether it’s stainless steel, aluminum, or a superalloy—is poured into the pre-heated shell.
• Shell Removing: After the metal cools and solidifies, the ceramic shell is broken away to reveal the metal tree inside.

Phase 3: Primary Finishing

The raw castings are separated from the tree and cleaned.

• Shot Blasting: We blast the parts to remove residual ceramic and scale.
• Grinding off Inlet: The gates where metal entered the part are ground flush to the surface.
• Initial Inspection: A visual check ensures no obvious defects exist before further processing.

Phase 4: Precision Finishing & Verification

This is where a rough part becomes a precision component ready for assembly.

• Pickling & Polish: Chemical and mechanical treatments are applied to achieve the required surface finish.
• CNC Machine Shop: We perform secondary machining for features requiring extremely tight tolerances.
• CMM Verification: Finally, we use a Coordinate Measuring Machine (CMM) to strictly validate dimensional accuracy against your blueprints.
