Premium Custom Castings from 10kg to 5T – Gray Iron, Ductile Iron, CGI & Carbon Steel for Global Industrial Applications

We are a professional foundry specializing in medium to large-scale custom castings, offering comprehensive solutions in gray iron, ductile iron, compacted graphite iron (CGI), and carbon steel. With advanced resin sand casting and iron mold覆砂 (furan resin-coated sand on metal molds) technologies, we produce high-integrity components weighing from 10 kilograms up to 5 metric tons—ideal for demanding sectors such as mining, energy, construction machinery, agriculture, and transportation.

Our dual-process capability ensures flexibility:

  • Resin sand casting delivers excellent surface finish and complex geometries for prototypes or low-volume orders.
  • Iron mold覆砂 process enables high productivity, consistent dimensional control, and reduced machining allowance for high-volume production.

All materials comply with international standards:

  • Gray Iron: HT250, HT300 (equivalent to ASTM A48 Class 30/40)
  • Ductile Iron: QT400-18, QT600-3 (ASTM A536 60-40-18 / 80-55-06)
  • CGI: RuT340, RuT400 (ISO 16112) – ideal for high thermal fatigue resistance
  • Carbon Steel: WCB, WCC, ZG270-500 – suitable for high-strength structural parts

Every casting undergoes rigorous quality control, including spectrographic analysis, tensile testing, and non-destructive testing (UT/MT upon request). We provide full documentation, including Material Test Reports (MTRs) and dimensional inspection certificates.

Key advantages:

  • Wide material selection to match performance requirements
  • Weight capacity up to 5T – among the highest in the industry
  • Precision machining services available in-house (CNC milling, boring, drilling)
  • Fast lead time: 30–45 days for first samples
  • Export experience: Serving customers in Europe, North America, Australia, and Southeast Asia

Whether you need a single prototype or annual supply of 500+ tons, our team supports your project from design validation to delivery.

Contact us today with your drawing or sample—we’ll deliver reliable, cost-effective castings that meet your exact specifications!
