Forging parts manufacturers specialize in shaping metal through compressive forces to produce high-strength components for critical applications. These industrial facilities operate various forging techniques to create parts with superior mechanical properties compared to cast or machined alternatives.
Forging Processes and Equipment
Modern forging manufacturers utilize several metal-forming methods:
- Closed-Die Forging (Impression Die Forging)
- Uses matched dies to shape heated metal blanks
- Produces near-net-shape components with tight tolerances (±0.015″)
- Typical capacities: 5-20,000 ton presses
- Common applications: automotive crankshafts, connecting rods
- Open-Die Forging
- Processes metal between flat dies with repeated blows
- Creates large, simple shapes (shafts, rings, cylinders)
- Equipment includes hydraulic presses (up to 60,000 tons) and hammer forges
- Roll Ring Forging
- Forms seamless rings by compressing and rolling preformed doughnuts
- Produces diameters from 6″ to 30+ feet
- Applications: bearing races, flanges, turbine rings
- Precision Forging
- Advanced closed-die process achieving near-final contours
- Minimizes machining requirements
- Tolerances reach ±0.005″ for critical aerospace components
Material Capabilities
Forging manufacturers work with various metal alloys:
- Carbon and Alloy Steels (1045, 4140, 4340)
- Stainless Steels (304, 316, 17-4PH)
- Aluminum Alloys (2014, 6061, 7075)
- Titanium Alloys (Grade 2, Grade 5)
- Nickel-Based Superalloys (Inconel 718, Waspaloy)
Material selection depends on application requirements for strength, corrosion resistance, and temperature tolerance.
Production Workflow
The manufacturing sequence typically involves:
- Billet Preparation
- Saw cutting or shearing to required weights
- Induction/heating to 1,100-2,300°F depending on material
- Forming Operations
- Pre-forming (blocking, edging)
- Finish forging in precision dies
- Flash removal (trimming)
- Post-Forging Processes
- Heat treatment (normalizing, quenching/tempering)
- Shot blasting for surface cleaning
- Non-destructive testing (UT, MT, PT)
- Machining to final dimensions
Quality Assurance Systems
Reputable forging manufacturers implement rigorous quality controls:
- Material Certification (MTRs to ASTM/AMS standards)
- Dimensional Inspection (CMM, optical comparators)
- Mechanical Testing (tensile, impact, hardness)
- Microstructure Analysis (grain flow verification)
- NDT Methods (ultrasonic, magnetic particle, dye penetrant)
Industry Applications
Forged components serve critical functions across sectors:
Automotive
- Engine parts (crankshafts, connecting rods)
- Transmission components (gears, shafts)
