Extreme-fine Gold Wire Drawing Machine

Extreme-fine Gold Wire Drawing Machine

The extreme-fine gold wire drawing machine is an ultra precision processing equipment that further draws the initial gold wire to below 0.01 mm through multiple micro nano level stretching processes.

Technical Difficulties

Extremely small diameter (close to lattice size, prone to fracture);
Significant surface effect (high risk of oxidation and pollution);
Tension control is extremely difficult (requires non-contact measurement);
Short mold lifespan (nanometer sized pore size is prone to wear).

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.
