The Importance Of Hole Design For Multi-Head Wire Drawing Dies

The core value of the hole design for multi-head wire drawing dies lies in ensuring the precision stability and production efficiency of multi-hole synchronous processing. Its significance is mainly reflected in the following aspects:

Analysis of key functions. 

Improve drawing efficiency: The multi-head design can process multiple wires at the same time, 200%-300% higher capacity than single-hole die, significantly lower energy and time costs per unit. 

Guarantee consistency: The symmetry of porous structure and parameter matching directly affect the tolerance of wire diameter: 

The deviation of the hole position axis should be less than 0.05mm/m; otherwise, it will cause tension imbalance and wire breakage. 

A difference in the length of the sizing tape exceeding ±5% will cause fluctuations in the wire reduction rate.

Design principle ‌ : The multi-head die must follow the "four same principles" - the same material base, the same grinding process, the same bore tolerance (±0.0005mm), and the same surface treatment to achieve high efficiency and stable production.
