OEM Customized Cast Iron Ductile Iron Sand Casting Foundry High Quality Casting Services Product

As a specialized OEM sand casting foundry, we deliver high-quality customized castings in gray iron and ductile iron for diverse industrial applications. Our expertise combines traditional foundry craftsmanship with modern technology to produce components that meet precise specifications while ensuring optimal performance, durability, and cost-efficiency for volume production.

Material Excellence and Metallurgical Precision
We specialize in engineering-grade iron castings with certified material properties:

• Gray Iron Castings (ASTM A48 Class 25B-40B): Delivering excellent vibration damping, machinability, and compressive strength for structural applications

• Ductile Iron Castings (ASTM A536 60-40-18, 65-45-12, 80-55-06): Providing superior tensile strength, impact resistance, and elongation characteristics through controlled nodularization treatment

• Alloyed Iron Variations: Special grades with nickel, chromium, or molybdenum additions for enhanced wear/corrosion resistance or elevated temperature performance

All melts are controlled through spectral analysis with full material certification and mechanical property verification.
