Product DescriptionCuttingBlanking is the initial stage in the forging process, where raw materials (e.g., steel ingots, bars, plates) are cut or segmented into specific sizes and shapes to prepare for subsequent forging operations (e.g., upsetting, punching, die forging).Saw Cutting: Ideal for high-precision, large-cross-section materials (e.g., alloy steel). Provides clean cuts but lower efficiency.Flame Cutting: Used for large billets (e.g., thick plates). Cost-effective but requires post-processing of the heat-affected zone.Shearing: High-speed method suitable for soft metals (e.g., aluminum, mild steel). May produce burrs on the cut edge.Laser/Plasma Cutting: High precision and automation, ideal for complex-shaped blanks.Breaking: Used for brittle materials (e.g., cast iron). Fast but requires controlled fracture surfaces.Heating Heating is a critical step in the forging process, where raw materials (billets, bars, or ingots) are heated to a specific temperature to improve plasticity and reduce deformation resistance. Proper heating ensures optimal metal flow during forging and enhances mechanical properties.Enhance Plasticity: Reduce yield strength for easier deformation.Minimize Cracking: Prevent material fractures during forging.Improve Microstructure: Promote uniform grain structure for better mechanical properties.Carbon Steels: 1,100–1,250°CAlloy Steels: 1,150–1,300°CAluminum Alloys: 350–500°CTitanium Alloys: 850–1,100°CForgingForging is a thermo-mechanical metal forming process that shapes heated or room-temperature metal billets using localized compressive forces (hammers, presses, or dies). It enhances mechanical properties by:a) Open-Die ForgingProcess: Deformation between flat dies with manual positioningAdvantage: Flexible for large/simple shapesExample: Ship propeller shafts >10 tonsb) Closed-Die ForgingProcess: High-pressure forming in engraved diesAdvantage: Tight tolerances (±0.3mm)Example: Automotive connecting rodsc) Precision ForgingProcess: Near-net-shape with minimal draft anglesAdvantage: Reduces machining by >70%Example: Aerospace fan bladesMachiningMachining of forged components is a critical post-forging process to achieve final dimensional accuracy, surface finish, and functional features. It bridges the gap between forged near-net-shape parts and end-use requirements.Quality ControlFirst Article Inspection: CMM verification of critical dimensionsSurface Integrity Check: White light interferometry for roughnessNDT Requirements: Dye penetrant testing after machiningCost Optimization TipsTooling: Use indexable inserts with multi-layer coatings (TiAlN/AlCrN)Fixturing: Magnetic chucks for thin-walled forgingsCoolant: High-pressure through-tool cooling (≥70 bar)Heat treatmentHeat treatment is an essential post-forging process that optimizes the mechanical properties of forged components through controlled heating and cooling cycles. It enhances strength, toughness, and dimensional stability while relieving internal stresses.Key ObjectivesAdjust Hardness/Toughness Balance (e.g., quench & temper)Refine Grain Structure for improved fatigue resistanceRelieve Residual Stresses from forging deformationAchieve Material-Specific Properties (e.g., case hardening for wear resistance)Hardness Testing: Rockwell/Brinell at multiple locationsMicrostructure Analysis: Grain size per ASTM E112NDT Methods: Ultrasonic testing for quench cracksPackaging Packaging ObjectivesPackaging is the final critical step in the forging supply chain, ensuring parts reach customers without damage while preventing corrosion during storage/transportation. Proper packaging combines protection, traceability, and handling efficiencyPhysical Protection – Prevent dents/scratches during transitCorrosion Prevention – Inhibit rust in humid/salty environmentsTraceability – Maintain batch/lot number visibilityHandling Optimization – Enable safe loading/unloading (weight/balance considerations)Forging Materials Selection & Application GuideThis reference table provides detailed specifications for common forging materials, including grade standards, forging temperature ranges, key properties, and typical applications to support design selection and process development.
