Industry-Specific Solutions

Automotive Manufacturers

Need lightweight, high-strength components? Our Gravity Sand Casting Parts like engine blocks and transmission housings meet ±0.2mm tolerances and ASTM B26 standards. Ideal for electric vehicle chassis and turbocharger housings.

Heavy Machinery Producers

Durable gearboxes and hydraulic valve bodies crafted from wear-resistant alloys (HB 200–300 hardness) withstand abrasive environments. Full NDT testing ensures weldability and dimensional stability.

Energy Sector

Wind turbine brackets and nuclear-grade housings pass ultrasonic testing (ASTM E164) and fatigue resistance checks. We comply with ASME and EN 1090 for renewable energy projects.

Valve & Pump Makers

Corrosion-resistant impellers and CF8M valve bodies tested to 1.5x working pressure. Surface finishes achieve Ra ≤6.3µm for leak-proof performance in harsh conditions.

Tailored for Your Needs

• Design Support: DFM analysis to optimize casting feasibility.
• Rapid Prototyping: 3D-printed sand cores/molds for fast sampling.
• Post-Processing: CNC machining, shot blasting, and custom heat treatments.

Built to Last: Rigorous Quality Checks

Every gravity sand casting part undergoes:

✅ X-ray/Ultrasonic Defect Detection

✅ Pressure Testing (API/ISO Compliance)

✅ Material Certification (EN, ASTM, JIS)

Global Reach, Local Support

• 15,000+ Tons/Year: Scalable production with regional warehouses in the EU, NA, and ASEAN.
• End-to-End Logistics: INCOTERM compliance, consolidated shipping, and REACH/ROHS documentation.

Trusted by Industry Leaders

Case Study: Gravity Sand Casting Parts reduced lead times by 20% for a German automotive Tier 1 supplier through optimized tooling.
