Copper wire stripping machine: scrap wire into pure copper “steel surgeon”

Piles of waste cables next to a steel beast is a low rumble. Operators will be wrist thick cable into the 

feed port, instantly ringing metal friction hiss - just three seconds later, the incision gushed out of the 

golden-red shiny copper, while the rubberized skin such as molted snakeskin like a complete peeling. 

This is the modern copper wire stripping machine, with mechanical precision and power, in the waste 

cable to dig out the flow of “red gold”.


The efficiency revolution under the blade


Traditional manual stripping, workers holding a blade on the cable to cut a spiral incision, not only inefficient, 

more likely to cut the copper core. The core breakthrough of modern stripping machines lies in replacing manual 

labor with rigid machinery to achieve millisecond precision cutting:


Adaptive Knife Holder System

Hydraulically driven alloy knife wheels automatically adjust the spacing according to the wire diameter. The tip of 

the knife touches the skin with an accuracy of 0.05mm when encountering 25mm² of fine wire, or applies 300kg of 

pressure to break through thick insulation when faced with 240mm² of thick cable. Laser sensors calibrate the depth 

of the knife in real time, ensuring that the copper core is not harmed.


Three-axis rotary skinning technology

The cutter head rotates at high speed while cutting, and the axial rotation of the cable conveyor rollers creates a 

helical cutting trajectory. This “rotary” stripping is 40% more efficient than linear cutting, and is especially good at 

handling composite structures such as nylon braid and aluminum foil shielding.


Residual Skin Separation Device

The peeled insulation skin is instantly pumped away by the negative pressure pipe, and the debris is separated from 

the whole section of the skin by the vibration sieving device. The entire machine can handle up to 1.8 tons of waste 

wire per hour, equivalent to 30 skilled workers throughout the day workload.


Challenge of special cables: when machinery meets complex structures


Not all cables are easy to strip. In the face of the complex protection of modern cables, stripping machine evolved a 

special response ability:


Steel wire armored cables

The high-frequency hydraulic shear cuts off the outer steel wire armor first, and the magnetic drum automatically absorbs 

the broken steel tape before the knife set cuts into the inner insulation. The entire process is completed in less than 6 seconds, 

avoiding the steel wire from wrapping around the cutter shaft.


Flat Data Harness

A visual recognition system locates the edges of the harness and a miniature disc knife set synchronizes the cutting of 

multiple side-by-side cables. Special rubberized pressure rollers keep the wires passing through straight and ensure that 

the very fine 0.3mm thick cores are not pulled off.


Oil-impregnated mining cable

Integrated solvent spraying system in the fully enclosed stripping chamber flushes away oil and coal dust adhering to the 

copper wire while stripping. Hot air drying device stabilizes the surface resistance value of output copper wire below 0.017Ω/mm².


Intelligent control system: let the machine learn to “think”.


The core competitiveness of the new generation of stripping machine is hidden in the chip of the control cabinet:


Material self-learning database

stores 137 common cable parameters (PVC/XLPE/Silicone rubber, etc.). When encountering a new wire type, the equipment 

automatically carries out a small test cut, analyzes the hardness of the material through the current fluctuation, and dynamically 

generates the best cutting parameters.


Real-time monitoring of copper loss

online spectrometer scans the surface of the outgoing copper every 5 seconds to detect whether the copper content is lower than 

99.9%. When abnormal loss (>0.8%) is detected, it immediately stops the machine for alarm and indicates tool wear or pressure 

abnormality.


Remote Operation and Maintenance System

Vibration sensor monitors the spindle bearing status and warns of potential failures 72 hours in advance. Operators view the 

day's copper wire output purity curve, energy consumption statistics and remaining tool life via mobile APP.


Green Recycling: Environmental Accounts per Ton of Waste Wire


Stripping machine is not only an efficiency tool, but also an environmental pioneer:


Reduced dioxin emissions by 3.2 kg per ton of scrap wire compared to traditional incineration method


Copper metal recovery rate increased from 92% to 99.5%.


The value of recycled plastic pellets made from crushed insulating rubber skins is increased by 5 times.


The energy consumption of the equipment is only equivalent to 1/18 of the same processing capacity of the smelting furnace.


In the deafening workshop of the metal recycling plant, the copper wire stripping machine continues to throughput the city's 

“metal vein”. When the stripped copper wire in the aggregate box stacked dazzling orange-red, those who had been buried in

 the depths of the rubber conductor regained new life - they will once again into the transformer, motor windings or 5G base 

station, complete the closed loop of the resource cycle. With its precise blade and intelligent “brain”, this steel beast opens up 

a metal path to a sustainable future in the jungle of waste cables.
