Discover Our End-To-End Lost Wax Casting Services
As your trusted investment casting manufacturer, we use genuine raw materials and advanced casting methods to ensure your casting parts production runs smoothly.
Here’s what we do best to give you high-quality components
Precision Wax Pattern & Shell Building
We start with wax patterns that are accurate to ±0.05 mm. Your patterns are injected via automated presses into multi-layer ceramic shells, built for uniformity and minimal deviation.
Clean Melting & Controlled Pouring
Dual induction furnaces (150 kg and 300 kg) melt your selected alloy to the exact chemistry. Controlled pouring reduces turbulence, resulting in defect-free, dimensionally stable castings.
In-House CNC Machining
We save you time and cost with 5 CNC lathes and 3 VMCs, delivering net-shape or near-net-shape parts with a Ra finish of 1.6–6.3 µm and VDG P690 D1/D2 tolerance.
Surface Finishing
Your parts receive the final touch with shot or bead blasting, passivation, plating, or custom coatings—all done under one roof.
Full Testing & Certification
Our NDT lab runs PMI, ultrasonic, radiography, hardness, spectrometry, and impact tests. You get digital test reports tied to each batch for full traceability.

What is lost wax investment casting?
Lost wax investment casting is the process where wax patterns are encased in ceramic, the wax is melted out, and metal is poured in, resulting in high-precision, complex parts.
Which alloys can you cast?
We cast from 50+ grades, both ferrous and non-ferrous. You can choose from carbon and low-alloy steels, stainless steel, duplex, Inconel, Hastelloy, cobalt, bronze, and more.
What is your lead time?
We complete prototypes in 4–6 weeks and production in 6–10 weeks. Expedited delivery available.
Do you offer CNC machining and coatings?
