Cold drawing

Cold drawn wire, also referred to as piano wire or music wire, is extensively used across a wide range of spring and forming applications, where precision and strength are essential. The combination of smooth surface finish and tight tolerances makes it suitable for both spring manufacturing and forming applications.

The material is typically made from unalloyed carbon steel with a carbon content between 0.5 and 0.8 percent, providing high strength and durability. The mechanical properties are achieved directly through the drawing process. During the process the wire is pulled through a die to reduce its diameter. This results in high dimensional accuracy, improved tensile strength, and enhanced surface quality. As the wire diameter is reduced, the strength and hardness increase, enabling the material to meet demanding application requirements. 

The process is carefully controlled to ensure consistent mechanical properties and reliable performance in further processing and end-use applications. Precision is at the core of our cold drawing process. By refining the surface and controlling dimensional tolerances, we produce wire with consistent quality and reliable mechanical performance.

Through continuous development of our processes, we continuously enhance the application range of our cold drawn wire and we maintain a strong focus on quality and consistency. By utilizing in-house tool-making capabilities, we optimize the drawing process and ensure high precision in every production step. Each batch of wire is produced and tested to meet both our internal standards and specific customer requirements.
