OEM Precision Forging Services for Mining Machinery - Custom Carbon Steel & Aluminum Components
Product Overview
We specialize in high-performance precision forging for mining machinery, delivering custom-engineered carbon steel and aluminum components that withstand extreme operating conditions. Our OEM forging services combine advanced metallurgy with precision manufacturing to produce durable, high-strength parts for heavy-duty mining applications.
Key Features & Benefits
✔ Material Expertise – High-grade carbon steel (1045, 4140, 4340) & aluminum alloys (6061, 7075) for optimal strength-to-weight ratios.
✔ Precision Forging Process – Closed-die/hot forging with tight tolerances (±0.2mm) to reduce machining needs.
✔ Customization – Tailored designs for crusher parts, drill bits, loader components, and more.
✔ Enhanced Durability – Superior grain structure for impact resistance, wear reduction, and fatigue life.
✔ Heat Treatment Options – Quenching, tempering, and annealing to meet hardness & toughness requirements.
✔ Cost Efficiency – Near-net-shape forging minimizes material waste and secondary processing.
