What we make in this category
Closed Die Forgings
闭式模锻件Near-net-shape parts with tight dimensional repeatability — the standard choice for medium to high volume structural components.
Typical parts- Gear blanks
- Connecting rods
- Forks & yokes
- Levers
Open Die / Free Forgings
自由锻件Large, low-volume parts where tooling cost is not justified. Ideal for shafts, rings, discs and blocks.
Typical parts- Large shafts
- Rolls
- Blocks & discs
- Press platens
Cold Forging & Cold Extrusion
冷锻 / 冷挤压件High dimensional accuracy and excellent surface finish with minimal machining allowance.
Typical parts- Fastener blanks
- Sleeves
- Gear preforms
- Precision pins
Ring Forgings & Rolled Rings
环锻件 / 辗环件Seamless rings with grain flow oriented to the service load — the standard for bearings, gears and flanges.
Typical parts- Bearing rings
- Gear rings
- Flange rings
- Slewing rings
Forged Shafts, Gears & Gear Blanks
锻造轴类 / 齿轮 / 齿坯Forged blanks rough or finish machined, heat treated and tested to your mechanical specification.
Typical parts- Transmission shafts
- Gear blanks
- Pinions
- Spline shafts
Forged Flanges, Fittings & Rigging
锻造法兰 / 管件 / 索具Pressure-containing and lifting components require the material documentation and traceability specified for the application.
Typical parts- Weld neck flanges
- Lifting hooks
- Shackles
- Turnbuckles
