After Copper Wire Press-Squaring on a Copper-Wire Press-Squaring Machine, What Causes Edge Fly Wires?

Oct 14,2026

After multi-strand copper wire is press-squared on the copper-wire press-squaring machine, fine copper wires that spread and stick up at the edge are called fly wires.

I Hazards of Edge Fly Wires after Press-Squaring

1.After fine wires detach, they easily cause short circuits and arcing

2.Edge copper wires are damaged and broken, reducing the conductive area

3.Scattered copper-wire chips contaminate tooling and equipment, interfering with subsequent welding and assembly processes

II Main Causes of Edge Fly Wires

1.Press-squaring mold structure and wear problems

2.Improper setting of press-squaring process parameters

3.Copper-wire incoming material and pretreatment factors

4.Tooling positioning and loading-operation problems

III Key Points for Improvement and Control

1.Optimize and maintain the press-squaring mold

2.Rationally debug the press-squaring process

3.Do good incoming-material control and preliminary arrangement

4.Standardize loading and tooling management
