Are you seeking a professional investment casting partner capable of delivering custom components with tolerances of ±0.08 mm, surface finishes of Ra ≤ 3.2 µm, and export-grade quality?
LOSTWAXCASTING CDL JOINT STOCK COMPANY – a leading specialist in thin-shell investment casting in Vietnam – provides premium custom-made casting services for Stainless Steel, Carbon Steel, and Alloy Steel. With a robust capacity of 60 tons/month, a modern 10,000 m² facility, and ISO 9001:2015 certification (No. 9199302839085-QMS, issued March 13, 2025), we are committed to transforming your technical drawings into perfect products within 7–21 days.
1. Why Choose CDL’s Custom Investment Casting Services?
- 100% Tailored to Your Needs: We cast precisely based on 2D/3D drawings, physical samples, or design concepts. Achieving CT4–CT6 (ISO 8062) tolerances, our process is ideal for complex, thin-walled components (wall thickness ≥ 0.8 mm), significantly reducing the need for secondary machining.
- Diverse & High-Grade Materials:
- Stainless Steel: 304, 316, 316L, Duplex 2205, Super Duplex.
- Steel: Carbon Steel (WCB, 1045), Alloy Steel (4140, 4340).
- Quality Assurance: 100% Spectrometer testing before pouring, accompanied by MTC Type 3.1/3.2.
- 10-Step ISO 9001:2015 Process: From wax injection → 12–15 layers of slurry dipping → 95–98% wax recovery → Mold firing (1000–1250°C) → Hot casting (1580–1600°C) → Shell removal → 2-stage shot blasting → Surface treatment → Closed-loop acid cleaning. The entire process is strictly controlled with a defect rate of < 3%.
- Superior Surface Finish & Precision:
- Surface roughness: Ra ≤ 3.2 µm (Grade 2 ASTM E125).
- 100% NDT Testing: Dye Penetrant (DP), Ultrasonic (UT), Radiographic (RT).
- Compliance with FDA, HACCP, ABS, DNV, PED, and IATF 16949 standards.
- Cost & Time Efficiency:
- Reduce machining costs by 30–50% due to high “as-cast” precision.
- Efficient material usage with 95–98% wax reuse and 92–95% scrap recovery.
- Rapid Lead Times: 7 days for prototyping, 14–21 days for mass production.
2. Typical Applications of Our Custom Services
- Food & Pharmaceutical: Burner components, valves, couplings (SS316L, Ra ≤ 1.6 µm, FDA compliant).
- Marine & Shipbuilding: Propellers, structural components (Duplex 2205, Steel 4340, ABS/DNV certified).
- Automotive & Mechanical: Gears, shafts, gearbox components (Alloy Steel 4140/4340).
- Water & Construction: Floor drains, pipe fittings (SS304/316).
- Trusted by major partners including THACO, Yamaha, Hyundai, Ford, and Piaggio.
