High precision investment moulding process for complex metal parts with tight tolerances superior surface finish and custom alloys.
What is the Investment Moulding Process?
Are you struggling to achieve complex internal geometries while keeping material waste and machining costs down? That is exactly the engineering challenge the investment moulding process solves.
Widely known as perdita-vaksa fandado, this is a highly precise near-net shape manufacturing method. We create a perfect, disposable wax pattern, coat it in a specialized ceramic slurry to build a rigid mold, and then melt the wax away. This leaves a flawless, heat-resistant cavity ready for molten metal.

We do not just rely on traditional foundry techniques; we elevate them. At vastmaterial, we integrate advanced data analytics and real-time monitoring into every stage of the production line.
- Aerospace-Grade Precision: We guarantee exact dimensional tolerances straight out of the mold, drastically reducing your need for secondary machining.
- Real-Time Process Monitoring: Continuous tracking of slurry viscosity, shell curing temperatures, and molten metal flow ensures zero defects and consistent metallurgical integrity.
- Cross-Industry Performance: We engineer rugged, high-tolerance components built to survive the extreme, high-stress environments of the industrial, energy, and automotive sectors.
Step-by-Step: The Investment Moulding Process
At Vastmaterial, our investment moulding process follows a strictly controlled workflow to deliver near-net-shape perfection. Here is exactly how we turn your designs into high-precision metal parts:
- 1. Tooling & Wax Pattern Injection: We start by machining a precise master die. From there, we use wax pattern injection molding to shoot liquid wax into the cavity, forming a perfect replica of your final part’s geometry.
- 2. Wax Tree Assembly: To maximize production efficiency, we attach multiple wax patterns to a central wax sprue. This creates a casting cluster, commonly called a “wax tree.”
- 3. Ceramic Shell Building: We dip the wax tree into a liquid ceramic slurry, followed by a stucco coating of fine sand. We repeat this ceramic shell casting process multiple times to build a tough, highly heat-resistant shell.
- 4. Dewaxing & Burnout: The shell is then heated to melt out the wax. This dewaxing casting method leaves behind a precise, hollow cavity. ly, we fire the shell at high temperatures to cure the ceramic so it can withstand molten metal.
- 5. Metal Pouring: Inside our advanced lost-wax casting foundry, we pour liquid metal directly into the pre-heated shells. Whether you need standard stainless steel or specialized custom alloy cast components, cURL Too many subrequests.
