Hot Forming & Cold Forming – The Right Technology for Your Requirements

Hot and Cold Forming – The Right Technology for Your Needs

In the world of fasteners, choosing the right forming process is essential to ensure a component’s quality, durability, and cost-effectiveness. At Pattberg Mechanical Components, we use two proven methods—hot and cold forming—each tailored to the specific needs of your projects.

Hot Forming: Ideal for Complex Geometries and Larger Parts

Hot forming occurs at high temperatures, ranging from 1100 to 1150 °C, making the material highly malleable. This method is optimal for parts with complex shapes and high degrees of deformation. It also enables the production of larger parts in medium-sized series, which are commonly used in the automotive or mechanical engineering industries. After the forging process, the blanks are often mechanically finished and tempered to ensure even higher durability.

• High formability, even with complex part geometries
• Suitable for medium-sized quantities and safety-critical applications
• Efficient for the production of larger parts

Cold Forming: Precision at Room Temperature and High Volumes

Cold forming, also known as cold extrusion, is carried out without heating the material, offering high dimensional accuracy and surface quality. This process is particularly suitable for the production of smaller parts (less than 20mm in diameter) in large volumes, as it allows for efficient mass production.

• High precision and dimensional stability of parts
• Efficient for large series and smaller diameters (less than 20mm)
• Competitive production times through fast manufacturing
• Work hardening

When to Use Each Process?

The choice between hot and cold forming depends on your project’s requirements. While hot forming is ideal for larger parts, complex geometries, and medium quantities, cold forming is particularly suitable for precise and smaller parts in high volumes.
