Detailed Product Description

OEM Forged & CNC Machined Components High-Tolerance Precision Forging Services

Advanced Manufacturing for Demanding Industrial Applications

We specialize in high-precision OEM forging and CNC machining, delivering custom-engineered components that meet the most stringent performance requirements. Our closed-die forging, precision CNC machining, and finishing processes ensure superior strength, dimensional accuracy, and durability—ideal for critical applications in aerospace, automotive, oil & gas, heavy machinery, and defense.


1. Precision Forging Services
Closed-Die (Impression Die) Forging
• Process : Heated billets are pressed into custom dies under extreme pressure, forming near-net shapes with excellent grain flow.
• Benefits :
◦ Higher strength-to-weight ratio vs. casting or machining.
◦ Improved fatigue & impact resistance due to optimized grain structure.
◦ Reduced material waste compared to traditional machining.
• Materials : Carbon steel, alloy steel, stainless steel, titanium, aluminum, brass.
Open-Die Forging
• Process : Used for large, simple shapes (shafts, rings, blocks) where dimensional tolerances allow secondary CNC machining.
• Applications : Heavy industrial components like rolls, cylinders, and large flanges.
Cold & Warm Forging
• Cold Forging : Room-temperature forming for high-strength, tight-tolerance parts (fasteners, gears).
• Warm Forging : Reduced heating for better formability than cold forging, with improved mechanical properties.


2. High-Precision CNC Machining

After forging, parts undergo CNC turning, milling, grinding, and EDM to achieve ultra-tight tolerances (±0.001" or better).

Key CNC Machining Capabilities :

✔ 5-Axis CNC Milling – Complex geometries with high accuracy.
✔ CNC Turning – Precision shafts, bushings, and threaded components.
✔ Grinding (Surface/Cylindrical) – Ultra-fine finishes (Ra 0.2µm or better).
✔ Gear Hobbing & Shaping – High-accuracy gear manufacturing.
✔ EDM (Wire & Sinker) – Intricate contours and hardened materials.
