Machine accuracy
The precision of cold forged components is typically expressed in terms of dimensional tolerances, which can range from ±0.001 (or thousandths of an inch) for general-purpose components to a few micrometers for high-precision applications. Cold forging is particularly advantageous for producing components with complex geometries, intricate details, and tight tolerances that would be challenging or impossible to achieve through other manufacturing processes. Industries such as aerospace, automotive, and electronics heavily rely on the high precision and repeatability offered by cold forged components to ensure reliable performance and functionality.
To maintain consistent precision and dimensional accuracy, manufacturers must implement rigorous quality control measures, including in-process monitoring, statistical process control, and regular inspections using coordinate measuring machines (CMMs) or other metrology equipment.

Our factory's cold heading process ensures that our components achieve a defect rate of 0 PPM (parts per million), meaning that we produce parts with zero defects, resulting in exceptionally high-quality products.
Material
Cold forging, also known as cold heading or cold forming, is a metalworking process that involves the plastic deformation of metals at or near room temperature to produce various components or parts. The selection of materials for cold forging is crucial as it affects the quality, strength, and performance of the final product. Here are some commonly used materials for cold forging:
Carbon Steels
Carbon steels are the most widely used materials for cold forging. They are classified into low-carbon steels (C ≤ 0.25%) and medium-carbon steels (0.25% < C ≤ 0.6%). Low-carbon steels offer excellent plasticity and ductility, making them suitable for small and thin-walled components. As the carbon content increases, the strength and hardness of the steel increase, making it suitable for larger and thicker-walled parts. Typical carbon steel grades used in cold forging include 10#, 20#, 35#, and 45#
Alloy Steels
To further enhance the strength and wear resistance of cold forged parts, alloy elements such as manganese (Mn), chromium (Cr), and nickel (Ni) are added to structural steels. Common alloy steel grades used in cold forging include 35CrMo, 40Cr, and 40CrNiMo. Alloy steels not only possess high tensile strength but also exhibit good ductility, making them ideal for producing complex-shaped components.
Stainless Steels
Stainless steels are widely used for cold forged components that require excellent corrosion resistance. Common stainless steel grades for cold forging include austenitic grades like 304 and 316, as well as martensitic grades like 410 and 420. While stainless steels generally have good plasticity, they are more challenging to work with compared to carbon and low-alloy steels.
Aluminum and Aluminum Alloys
Aluminum and its alloys are widely used in the aerospace industry due to their low density. Common aluminum and aluminum alloy grades used in cold forging include 1060, 6061, and 7075. Although aluminum alloys offer high strength, their good thermal conductivity can lead to localized softening during the cold forging process, which requires careful control.
Copper and Copper Alloys
Copper and copper alloys are known for their excellent thermal and electrical conductivity, making them suitable for producing electrical contact components. Common copper materials used in cold forging include oxygen-free copper, electrolytic tough pitch copper, and copper alloys such as brass and beryllium copper. Copper materials are relatively soft, and special attention is required during cold forging to prevent delamination.
In addition to the aforementioned metallic materials, certain high-performance polymers, such as nylon, can be used to a limited extent for cold forging applications. Different materials offer varying advantages and disadvantages in terms of cost, workability, and performance characteristics.
