Product DescriptionOEM Forging & CNC Machining Services – One-Stop ManufacturerBestPro Precision Manufacturing specializes in custom forged metal parts combined with CNC machining.With over 15 years of experience, we deliver hot forging, cold forging, open-die forging, closed-die forging, and precision forging solutions for industries including automotive, aerospace, railway, heavy machinery, oil & gas, and energy.Processes DescriptionProcessKey FeaturesTypical ApplicationsCommon MaterialsSurface FinishDimensional AccuracyCostOpen-Die Forging- Uses sand mold- Suitable for large or complex partsLarge shafts, rollers, pressure vesselsCarbon steel, alloy steel, stainless steel********Closed-Die Forging- Metal is pressed into a die cavity- High volume, near-net shapeAutomotive parts, tools, gear blanksAlloy steel, carbon steel, aluminum, copper************Cold Forging- Deformed at room temperature- Excellent finish and tolerancesFasteners, shafts, precision componentsCarbon steel, stainless steel, aluminum************Hot Forging- Formed at intermediate temperature- Balance of strength and precisionAutomotive gears, suspensions, fittingsAlloy steel, aluminum alloys***********Precision Forging- Near-net shape with minimal machining- Tight tolerance and high finishAerospace components, connecting rodsTitanium, nickel alloys, high-grade steels***************One-stop ServiceUnlike suppliers who only deliver raw forgings, we provide complete one-stop production:Forging → Heat Treatment → CNC Machining → Surface Finishing → Assembly → Export Packaging.This ensures stronger, more reliable, and ready-to-use forged parts tailored to your requirements.Contact BestPro today for custom forged & machined parts with unbeatable strength, precision, and reliability.Machining and ApplicationValue-Added Services for Forged PartsProcessDescriptionKey Features / NotesHeat TreatmentImproves strength, hardness, and toughness by controlled heating and cooling.Includes quenching, tempering, normalizing, annealing. Controls internal stress.CNC MachiningPrecision turning, milling, drilling, or tapping after forging.Achieves tight tolerances. Requires proper fixturing and design for machining.Surface TreatmentImproves appearance, corrosion resistance, or wear resistance.Options: sandblasting, black oxide, phosphating, zinc plating, anodizing, painting.Nondestructive Testing (NDT)Detects surface or internal defects without damaging the part.Includes ultrasonic, magnetic particle, and dye penetrant testing.Material & Mechanical TestingConfirms chemical composition and mechanical strength.Includes hardness, tensile, impact tests. 3.1 certificates available.Die Design OptimizationImproves forging die life and product quality.Reduces defects and production cost. Important for stable mass production.Custom Packing & LabelingTailored packaging with labeling or barcodes based on customer needs.Options: wooden crates, pallets, rust protection, custom logos, barcode stickers.Pre-Assembly (Optional)Assembles forged parts with other components (e.g., bushings, pins, etc.).Saves customer assembly time. Requires clear fit and orientation requirements.AdvantagesForging vs Casting vs CNC Machining – Comparison TableAspectForgingCastingCNC MachiningStrength*****Excellent grain flow, highest mechanical strength**May contain internal defects like porosity****Good, but grain structure not optimizedPrecision***Moderate; better in closed-die forging**Low to moderate, depends on process*****High precision, tight tolerancesSurface Finish**Requires post-machining or polishing***Better in die/investment casting*****Excellent, depending on tooling and settingsMaterial Utilization****Less waste than machining***Moderate, some gating/risers lost**Higher waste due to cutting/removalTooling Cost****Moderate to high (dies required)***Low for sand casting, high for die casting**Low, mainly tooling and fixturingProduction Volume****Medium to high volumes****Suitable for both small and large batches**Best for low to medium volume, or prototypingApplication ExamplesAutomotive shafts, aerospace parts, oil & gas componentsEngine housings, pump bodies, structural partsPrecision housings, brackets, covers, prototypesFor maximum strength and safety-critical partsFor complex shapes, moderate precision, and high-volume production For high precision, complex geometries, or low to medium volumes → Choose ForgingIdeal for shafts, gears, and structural components in aerospace, automotive, and heavy industry.→ Choose CastingSuitable for housings, pump bodies, engine blocks, and structural components.→ Choose CNC MachiningPerfect for precision brackets, enclosures, custom parts, and prototypes.Quality Assurance & Quality ControlOur integrated quality assurance (QA) and quality control (QC) systems ensure the highest production standards. ISO standard certifications upholds our quality management system, while the QC team conducts detailed inspections using advanced, calibrated equipment like CMM, VMS, calipers, and hardness testers etc.. This dual approach "focused on prevention and precise inspection" ensures all parts meet stringent specifications and customer requirements, maintaining top precision, performance, and reliability.Basic InformationQC System100% inspection before shipmentDrawing formatCAD / PDF/ DWG/ IGS/ STEPPackagingStandard package / Carton box or Pallet / As per customized specificationsTesting equipmentCMM (Coordinate Measuring Machine), VMS, Height gauge, Caliper, Hardness tester, Roughness tester, Projector machine, Pin/Angle/Block/Plug/Thickness/Thread/Radius gauge, etc.Trade termsEXW, FOB, CIF, As per the customer's requestShipment Terms1) 0-100kg: express & air freight priority2) >100kg: sea freight priority3) As per customized specificationsNoteAll CNC machining parts are custom-made according to the customer's drawings or samples, with no stock.
