Investment (Vacuum) Casting

TMetal produces high-precision investment castings with excellent surface fnish and minimal machining needs, reducing cost and lead time. By integrating 3D printing, we deliver complex parts faster and more economically. Alloys include cobalt-, nickel-, and iron-based materials for industries like oil & gas, power, automotive, and petrochemical.

Investment (Vacuum) Casting Production Equipments

Shell-making Robotic Arm

TMetal’s shell-making robotic arm is built for precise investment casting of cobalt and other superalloys. It features a 6-axis vision-guided arm (±50 μm accuracy), climate-controlled coating chambers, multi-layer refractory capability for >1450 °C, and intelligent algorithms for consistent 0.15 ± 0.02 mm coating. Ideal for complex parts like turbine blades and aerospace components. The system’s closed-loop control ensures precise dimensions and shell integrity, keeping defect rates below 0.5%—ideal for superalloy casting.

Automated Dewaxing and Wax Recycling System

Our specialized dewaxing system delivers exceptional performance:

High-pressure steam dewaxing (0.8–1.2 MPa) completes in 6–8 minutes with 99.8% efficiency. A three-stage wax recovery system—primary filtration, molecular sieve (1 μm), and vacuum purification (<50 ppm O2)—restores wax to aerospace-grade purity (≤0.008% ash) for up to 15 reuse cycles. Precision thermal control (±0.5 °C) protects shell integrity.

This integrated system reduces wax consumption by 85–90% while meeting the strict quality standards required for cobalt- and nickel-based superalloy casting.
