Process | Key Features | Typical Applications | Common Materials | Surface Finish | Dimensional Accuracy | Cost |
Open-Die Forging | - Uses sand mold - Suitable for large or complex parts | Large shafts, rollers, pressure vessels | Carbon steel, alloy steel, stainless steel | ** | ** | **** |
Closed-Die Forging | - Metal is pressed into a die cavity - High volume, near-net shape | Automotive parts, tools, gear blanks | Alloy steel, carbon steel, aluminum, copper | *** | **** | ***** |
Cold Forging | - Deformed at room temperature - Excellent finish and tolerances | Fasteners, shafts, precision components | Carbon steel, stainless steel, aluminum | **** | ***** | *** |
Hot Forging | - Formed at intermediate temperature - Balance of strength and precision | Automotive gears, suspensions, fittings | Alloy steel, aluminum alloys | *** | **** | **** |
Precision Forging | - Near-net shape with minimal machining - Tight tolerance and high finish | Aerospace components, connecting rods | Titanium, nickel alloys, high-grade steels | ***** | ***** | ***** |
Value-Added Services for Forged Parts | ||
Process | Description | Key Features / Notes |
Heat Treatment | Improves strength, hardness, and toughness by controlled heating and cooling. | Includes quenching, tempering, normalizing, annealing. Controls internal stress. |
CNC Machining | Precision turning, milling, drilling, or tapping after forging. | Achieves tight tolerances. Requires proper fixturing and design for machining. |
Surface Treatment | Improves 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 Testing | Confirms chemical composition and mechanical strength. | Includes hardness, tensile, impact tests. 3.1 certificates available. |
Die Design Optimization | Improves forging die life and product quality. | Reduces defects and production cost. Important for stable mass production. |
Custom Packing & Labeling | Tailored 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. |
Forging vs Casting vs CNC Machining – Comparison Table | |||
Aspect | Forging | Casting | CNC Machining |
Strength | ***** Excellent grain flow, highest mechanical strength | ** May contain internal defects like porosity | **** Good, but grain structure not optimized |
Precision | *** Moderate; better in closed-die forging | ** Low to moderate, depends on process | ***** High precision, tight tolerances |
Surface Finish | ** Requires post-machining or polishing | *** Better in die/investment casting | ***** Excellent, depending on tooling and settings |
Material Utilization | **** Less waste than machining | *** Moderate, some gating/risers lost | ** Higher waste due to cutting/removal |
Tooling Cost | **** Moderate to high (dies required) | *** Low for sand casting, high for die casting | ** Low, mainly tooling and fixturing |
Production Volume | **** Medium to high volumes | **** Suitable for both small and large batches | ** Best for low to medium volume, or prototyping |
