Grey & Ductile (SG) Iron Casting Services
Engineered ferrous castings delivering high vibration dampening, compressive stability, and high-tensile structural integrity for heavy seating bases, industrial machinery, and automotive systems.
Ferrous Metallurgy & Molding Technologies
Specialized in high-density, defect-free iron pours with full microstructural nodularity checks and ultrasonic testing.
Grey Iron Casting (Flake Graphite)
Exceptional vibration damping capacity and excellent machinability, ideal for heavy seating pedestal footings, machine bases, and structural counterweights.
Ductile / S.G. Iron Casting (Spheroidal)
Offers steel-like tensile strength, high elongation, and superior impact resistance for high-stress pivots, brackets, and automotive safety components.
Weight Range & Foundry Envelopes
Single-piece heavy casting capability accommodated via automated green sand molding loops and resin-bonded no-bake mold lines.
Medium Frequency Induction Melting
Precise thermal management, metallurgical inoculation controls, and real-time optical emission spectrometry on every heat tap.
Core Making & Complex Cavities
High dimensional accuracy for complex internal water jackets, fluid passages, and lightweighted hollow structural ribs.
Heavy CNC Machining & Shot Blasting
Turnkey delivery of fully machined, cleaned, ultrasonic-tested, and primer-coated iron components ready for immediate line assembly.
