How to Choose a SemiAutomatic Stripping Machine for 1.0mm² Aviation TwinCore Cables
In the aviation cable industry, 1.0mm² twincore wires fall into a mediumsize range, but their processing difficulty is far greater than that of civilian cables. Aviationgrade insulation is harder, shielding layers are tighter, and conductor structures are denser. Therefore, choosing the right semiautomatic stripping equipment directly affects product yield, crimping quality, connection reliability, and the final system’s safety.
Below is a complete guide on how to select the proper semiautomatic stripping machine for 1.0mm² aviation twincore wires, from the aspects of structure, process, efficiency, compatibility, durability, and cost.
1. The Blade Structure Must Be Stable, Precise, and Adjustable
Aviation cables often use fluoropolymer insulation, aviationgrade PVC, or lowsmoke halogenfree materials. These materials are hard and require greater cutting force, so blade quality is essential.
● Microadjustable cutting depth
Incorrect blade depth may cause:
Too deep → damaged copper strands, broken shielding, poor crimping afterward
Too shallow → outer jacket cannot be removed cleanly, requiring rework
A blade holder with finetuning scales or precision knobs ensures stable and repeatable stripping.
● Synchronous dualblade opening
This keeps the cut symmetrical and prevents tilted or uneven strip edges.
● Highgrade tool steel
Essential for longterm use on hard insulation without producing burrs or deformation.
2. The Clamping System Must Handle “Soft + Tough” TwinCore Structure
Aviation twincore wires have tight spacing and torsion between the two cores. If the clamping system is unstable, problems occur easily:
Cable rotates during stripping
Excessive stretching causes deformation
Inconsistent strip lengths or exposed copper
Choose equipment with:
● Flexible clamping jaws
To secure the round twincore cable without flattening it.
● Constantpressure clamping mechanism
To prevent sudden pulling force from deforming the cable during stripping.
3. A Stripping Mode Designed for Hard Aviation Insulation
Aviationgrade jackets require stronger peeling force and more controlled cutting. The machine should include:
● Softstart cutting mode
The blade first “touches” the jacket lightly before fully engaging, reducing impact damage.
● Strong pulling force for jacket removal
Ensures clean stripping for tough insulation and avoids incomplete peel marks.
4. Efficiency: A SemiAutomatic Machine Should Be 3–5 Times Faster Than Manual Work
When evaluating efficiency, don’t just look at speed numbers. Instead, consider:
● Whether it supports continuous stripping
● Whether it has automatic clamp–release rhythm
● Whether full and halfstripping can be completed in one cycle
In aviation production, manual stripping typically reaches 200–300 pcs/hour, while a good semiautomatic machine can reach 800–1200 pcs/hour with much better consistency.
5. Compatibility: Can It Handle Shielded and DualLayer Structures?
Aviation twincore wires often have the following structure:
Hard outer insulation
Shielding layer (braid + foil)
Inner dualcore insulation
Therefore, the selected machine must support:
✔ Twostage stripping
Outer jacket → inner insulation.
✔ Shielded cable processing
Blade geometry should avoid disturbing the braided shield while cutting cleanly.
✔ Multiple cable sizes around 1.0mm²
Most aviation factories handle 0.5–1.5mm², so flexibility is essential.
6. Durability and Maintenance Cost Matter More Than You Think
Aviation cable production usually involves many small batches with frequent model switching. The machine must maintain stable performance over time.
Key considerations:
● Metal chassis with good vibration resistance
● Easytoreplace service parts
● Standardized blades and clamping components
● Simple daily maintenance (cleaning debris, replacing blades)
Longterm stability is far more important than peak speed.
