The Complete Guide to Forging Procedures for US Industrial Manufacturers & Engineers
Forging Procedures represent one of the oldest and most reliable metal shaping techniques in manufacturing. This comprehensive guide explores the essential processes, techniques, and applications of modern forging operations. Whether you’re an engineer, manufacturer, or procurement specialist, understanding these procedures is crucial for producing high-strength, durable components that meet rigorous industrial standards.
Understanding Forging Procedures and Their Importance
Forging is a manufacturing process that shapes metal through compressive forces, creating parts with superior strength characteristics compared to cast or machined components. The internal grain structure of forged metal follows the shape of the part, resulting in exceptional structural integrity and reliability at high stress points.
Modern forging operations combine traditional metalworking principles with advanced technology
For critical “cannot fail” components in aerospace, automotive, and heavy machinery applications, forging procedures deliver unmatched performance. At MAIKONG, we’ve refined these techniques to provide US manufacturers with exceptional quality forged components at competitive prices.

Classification of Forging Processes
Forging processes can be classified based on temperature, equipment used, and the specific techniques employed. Each approach offers distinct advantages depending on the material, desired properties, and application requirements.
Classification by Temperature
Hot Forging
Conducted at temperatures above the metal’s recrystallization point (typically 0.6 times its melting point). This process allows for significant deformation with relatively low force requirements but may result in less precise dimensions and rougher surface finish.
Warm Forging
Performed at intermediate temperatures between hot and cold forging. This approach balances formability with precision, offering a good compromise for many applications.
Cold Forging
Executed at room temperature or slightly elevated temperatures below recrystallization. Cold forging delivers excellent dimensional accuracy and surface finish but requires greater force and is limited in the degree of deformation possible.

Types of Forging Methods
Modern manufacturing employs various forging methods, each suited to specific applications and production requirements. At MAIKONG, we utilize multiple techniques to deliver optimal results for our clients.
Open Die Forging
In open die forging, metal is shaped between multiple strikes of a hammer on a flat or simply shaped die. This versatile method is ideal for large or custom components with simple geometries.
Closed Die Forging
Also known as impression die forging, this process shapes metal within the cavity of two dies that contain the negative of the desired part shape. Ideal for complex geometries and high-volume production.
Rolled Ring Forging
Specialized process for creating seamless rings by punching a hole in a round metal stock and then rolling and shaping it to the desired dimensions. Commonly used for bearings, gears, and aerospace components.

Essential Steps in the Forging Procedures
The forging process involves several critical stages that must be carefully controlled to ensure optimal results. Each step contributes to the final product’s quality, dimensional accuracy, and mechanical properties.
The complete forging workflow from raw material selection to finished component
Step 1: Die Design and Manufacturing
The foundation of successful forging begins with precise die design. Using advanced CAD/CAM systems, engineers create dies that will shape the metal into the desired form. Die quality directly impacts the final product’s dimensional accuracy, surface finish, and production efficiency.
Step 2: Material Selection and Preparation
Selecting the appropriate metal alloy and preparing it for forging is crucial. The material must have the right composition and properties to achieve the desired characteristics in the finished product. At MAIKONG, we carefully source and test all raw materials to ensure consistency and quality.
Step 3: Heating
Most forging operations require heating the metal to increase its plasticity. The specific temperature depends on the material and forging method. For steel, temperatures typically range from 850°C to 1150°C for hot forging, while aluminum forging temperatures are generally around 400-500°C.
Step 4: Forging Operation
During the actual forging operation, the heated metal is shaped using pressure applied by presses or hammers. This may involve multiple stages to gradually form the metal into the desired shape. The specific equipment and techniques used depend on the complexity of the part and production volume requirements.

Step 5: Trimming and Finishing
After forging, excess material (flash) is removed through trimming operations. Additional finishing processes may include machining, heat treatment, and surface treatments to achieve the final dimensions and properties required.
Step 6: Quality Control and Inspection
Rigorous quality control ensures that forged components meet all specifications. This may include dimensional inspection, material testing, and non-destructive evaluation techniques to verify structural integrity.
