Gray iron features flake graphite and provides excellent vibration damping and machinability. Nodular (ductile) iron has spherical graphite, offering significantly higher strength, toughness, and ductility, making it ideal for high-pressure engine components.
Yes, we specialize in OEM services. We can produce custom industrial metal parts based on your specific drawings, utilizing our experience in sand molding, lost-wax, and CNC machining.
Depending on the quantity and tolerance requirements, we recommend Lost Foam casting or Vacuum Moulding for highly intricate shapes, while resin sand casting is ideal for larger, robust components.
After the initial casting, we offer precision CNC turning, milling, surface grinding, engraving, and full sub-assembly work to deliver a finished, ready-to-use product.
We can produce precision machining parts ranging from 1mm to 300mm in various materials including cast iron, aluminum, stainless steel, and brass.
We strictly control the carbon (2.11%-4%) and silicon content, while managing impurities like manganese, sulfur, and phosphorus. Alloy elements are added as needed to enhance physical and chemical properties.
