Cold Drawing
A metalworking process where a tube or pipe is pulled through a die at room temperature to reduce its diameter and wall thickness while improving surface finish, dimensional accuracy, and mechanical properties.
Cold Drawing Process
Cold drawing is a precision metal forming process performed at room temperature. A hollow tube is pulled through a die (and over a mandrel or plug) to achieve tighter dimensional tolerances, improved surface finish, and enhanced mechanical properties through work hardening.
Advantages
- Tighter dimensional tolerances (±0.1mm)
- Superior surface finish (Ra < 0.8μm achievable)
- Improved mechanical properties
- Better concentricity
