Forging
Precision metal forming through controlled deformation for superior mechanical strength and durability.
Overview
Forging is one of the oldest and most reliable metalworking processes, used to shape metals under compressive forces through hammering or pressing. It enhances the internal grain structure of metals, improving mechanical properties such as strength, toughness, and fatigue resistance.
At EDS, we provide a full range of forging solutions — from small precision components to large industrial parts — ensuring optimal performance, dimensional accuracy, and cost efficiency. Our network of qualified forging partners supports both serial production and specialized low-volume projects.
Forging Methods
The forging process can be carried out using different methods depending on geometry, tolerances, and material requirements. EDS works with the main industrial forging techniques:
- Closed Die Forging: Metal is compressed within a precisely shaped die cavity for complex geometries.
- Open Die Forging: The workpiece is deformed between flat or simple-shaped dies for large components.
- Ring Rolled Forging: Produces seamless rings with excellent strength and structural integrity.
- Multi-Directional Forging: Applies pressure from multiple axes for highly accurate shapes and compact structures.
Temperature Classifications
Forging processes are categorized by the temperature at which the material is deformed — influencing surface finish, tolerances, and mechanical performance. EDS engineers select the most suitable approach based on part design, alloy composition, and production volume.
Hot Forging
In hot forging, metals are deformed above their recrystallization temperature (typically 950–1250°C for steel). This allows easy plastic deformation, excellent flow characteristics, and the ability to produce large or complex parts. Hot forging minimizes internal stress but requires additional machining for dimensional precision.
- Ideal for large and complex shapes
- Improved metallurgical structure and toughness
- Lower forming forces required
- Common materials: carbon steel, alloy steel, stainless steel
Warm Forging
Warm forging occurs at intermediate temperatures (typically 600–900°C), balancing the advantages of both hot and cold processes. It allows better dimensional control than hot forging, while still reducing forming forces compared to cold forging.
- Improved surface quality and dimensional accuracy
- Reduced tooling wear compared to cold forging
- Suitable for medium-sized parts requiring precise tolerances
Cold Forging
Cold forging is performed at or near room temperature, producing parts with excellent surface finish and close tolerances. It increases material strength through strain hardening, making it ideal for high-volume production of small precision components.
- High dimensional accuracy and repeatability
- Excellent surface finish
- Increased material hardness and strength
- Ideal for bolts, shafts, gears, and small precision parts
