Metal Forging Processes & Methods We Employ
Selecting the optimal forging method depends on component geometry, production volume, material grade, and mechanical strength requirements. TFG USA utilizes state-of-the-art forging presses and automated forging cells.
Closed-Die Forging (Impression-Die Forging)
Closed-die forging compresses heated metal within precision machined dies to create highly complex near-net shapes with tight dimensional tolerances. This process ensures continuous grain flow following the part contour, dramatically improving fatigue strength. Recommended for medium to high-volume production components such as crankshafts, connecting rods, gears, and structural brackets.
Open-Die Forging & Ring Rolling
Ideal for large industrial components, simple geometries, and lower volume applications. Open-die forging shapes metal between flat or contoured dies without completely enclosing the material. This method refines the internal micro-structure, improves density, and achieves high mechanical properties for heavy shafts, large flanges, discs, and seamless rolled rings.
Hot Forging
Hot forging processes metal above its recrystallization temperature (up to 1,250°C for steel), maximizing material ductility and reducing required forging force. Hot forging enables the production of complex, heavy-wall components while strain-hardening eliminates internal stress, producing exceptionally tough parts for mining, construction, and heavy agricultural equipment.
Cold Forging & Warm Forging
Cold forging is conducted at or near room temperature, offering superior surface finishes, exceptional dimensional accuracy, and zero scale formation. By work-hardening the metal, cold forging increases yield and tensile strength without thermal distortion. It is widely used for high-volume fasteners, automotive pinions, splines, and hydraulic valve bodies.
Upset & Precision Forging
Upset forging increases the cross-sectional area of a metal bar by compressing its length, making it ideal for shafts, valve stems, fasteners, and axial components. Precision forging produces near-net or net-shape components that minimize or completely eliminate the need for secondary finish machining, delivering significant material cost savings.

Frequently Asked Questions (FAQ)
Key technical and procurement insights for sourcing custom metal forgings.
What is custom metal forging and how does it improve part strength?
Custom metal forging is a thermal-mechanical shaping process that deforms metal under extreme compressive pressure using hammers or hydraulic presses. Unlike casting (which melts metal and creates random grain structures) or machining (which cuts across grain lines), forging forces the internal crystal structure to align continuously along the shape of the component. This results in superior yield strength, higher impact toughness, and exceptional fatigue resistance.
What is the difference between forged metal components and CNC machined parts?
Forging alters the internal physical properties of metal to maximize load-bearing capacity, making it the ideal choice for high-stress structural parts. CNC machining removes material from a solid billet or bar to create shapes. While CNC machining offers unmatched precision for intricate geometries, it disrupts the natural grain flow. TFG USA frequently combines both capabilities: hot or cold forging near-net shapes first, then utilizing multi-axis CNC machining for high-precision surfaces and tight-tolerance bores.
Is metal forging stronger than welding or metal casting?
Yes. Forging produces parts that are significantly stronger than cast or welded structures. Metal castings can suffer from internal gas porosity, shrink voids, and inclusions. Welded assemblies feature heat-affected zones (HAZ) susceptible to stress cracks. Forged components are 100% solid, dense, and uniform, providing long-term reliability under severe operating conditions.
What production volumes and part weights can TFG USA accommodate?
TFG USA specializes in medium to high-volume OEM production runs (typically 500 to 100,000+ units annually). Our global manufacturing infrastructure handles forged components ranging from small precision parts under 0.5 kg (1 lb) up to large open-die industrial forgings exceeding 500 kg (1,100 lbs).
