Extreme-fine Silver Wire Drawing Machine

Extreme-fine Silver Wire Drawing Machine

Extreme-fine silver wire drawing machine below 0.01 mm (10 μm) is a cutting-edge equipment in the field of metal microfabrication, specifically used for producing ultra precision silver wire required for high value-added products such as electronic packaging, microelectromechanical systems (MEMS), medical catheters, etc. This type of equipment represents the highest level of current metal wire processing technology.

Structure Characteristics

Due to its extremely high processing accuracy, the ultra-fine wire drawing machine has significant structural differences from traditional drawing machines, mainly including the following core modules:
Feeding
Ultra fine gold wire with an initial diameter of 10 µm or more. Adopting constant tension wire release to avoid wire breakage caused by tension fluctuations.
Stretching System
The mold is made of single-crystal diamond (SCD) or polycrystalline cubic boron nitride (PCBN) material. Ultra high precision polishing (Ra<5nm) to reduce friction and surface damage. The drawing method adopts multi pass micro stretching (with a reduction rate of less than 5% per pass).
Tension Control
Contactless measurement+closed-loop feedback to ensure tension fluctuation<0.1%.
Take-up System
Precision wire guide ensures even winding. Vacuum or inert gas environment winding to prevent oxidation.
