CO₂ Dual-Head Laser Wire Stripping Machine: A Revolutionary Solution for Precision Wire Processing
Abstract: As precision manufacturing demands in the electronics industry continue to rise, traditional mechanical wire stripping processes are no longer adequate for high-density, ultra-fine wire products. This article provides an in-depth analysis of the GW-DLS01 CO₂ dual-head laser wire stripping machine - covering its core technology, key performance specifications, and typical application scenarios - to help engineers and procurement decision-makers gain a comprehensive understanding of this advanced equipment.
What Is a CO₂ Laser Wire Stripping Machine?
A laser wire stripping machine uses a high-energy laser beam to precisely vaporize the insulating coating on the surface of a wire (such as enamel insulation on magnet wire or polyurethane film) without damaging the underlying metal conductor. Compared to traditional blade-type or thermal stripping processes, laser wire stripping offers three core advantages: non-contact operation, zero mechanical stress, and high repeatability - making it especially well-suited for precision processing of ultra-fine wire diameters down to 0.05 mm and high-density coil windings.
The CO₂ laser operates at a wavelength of 10,640 nm (10.64 μm), in the mid-to-far infrared band. This wavelength is highly absorbed by organic insulating coatings, enabling efficient vaporization of the enamel film with virtually no damage to the copper conductor, making it the dominant laser type for magnet wire stripping applications.

Dual-Head Dual-Optical-Path Design: The Core of Enhanced Productivity
The GW-DLS01 features a fully sealed dual-tube, dual-optical-path design - the defining technical differentiator that sets it apart from conventional single-head machines:
Doubled Production Output: Two independent optical path systems operate simultaneously. Compared to traditional single-tube equipment, the machine delivers at least twice the throughput. For high-volume stripping applications such as magnet wire coils and transformer windings, this translates directly into measurable capacity gains.
Imported RF Laser Sources: Both laser heads use genuine imported Metal RF CO₂ lasers. Compared to DC-excited glass-tube lasers, RF lasers deliver superior beam quality (better M² value), a significantly longer operational lifespan (typically exceeding 20,000 hours), and eliminate the need for periodic gas refills - resulting in substantially lower total cost of ownership.
High-Speed Galvanometer Scanning System: The machine is equipped with a high-speed galvanometer (galvo) scan head, enabling precise, high-velocity laser path control across the full 140×140 mm work area. This supports programmatic processing of complex stripping patterns.
Five Stripping Modes to Cover All Process Requirements
The GW-DLS01 comes with built-in professional wire stripping software supporting five processing modes, which can be combined within a single machining cycle:
1. Horizontal Cut: Circumferential cutting perpendicular to the wire axis. Ideal for end-stripping and removing insulation from defined-length segments.
2. Vertical Cut: Cutting along the wire axis. Suited for connection points where partial lateral coating removal is required.
3. H-Shape Cut: Combines horizontal and vertical cuts to create an H-shaped stripping area. Commonly used for mid-span stripping of flat wires or ribbon cables.
4. Micro Window Cut: Precisely opens a micro-sized window in the insulation layer to expose a minimal conductor area. Ideal for solder pad pre-treatment and sensor contact point preparation.
5. Grating Cut: Processes the insulation surface in a grid pattern to increase surface roughness in the stripped zone, improving adhesion for subsequent soldering or bonding operations.
Software Advantage: Operators can freely configure processing position, stripping dimensions, laser power, and scan speed. Programs can be saved and recalled for batch production, minimizing changeover time and setup costs.
Key Technical Advantages
① Ultra-Low Energy Consumption & Green Manufacturing
Rated power consumption of under 1.5 kW places the GW-DLS01 among the most energy-efficient machines in its performance class. Running 8 hours per day, daily electricity consumption is approximately 12 kWh - fully aligned with the manufacturing industry's long-term goals for energy reduction and carbon neutrality.
② Long Service Life & Maintenance-Free Operation
The Metal RF laser is designed for over 20,000 hours of operational life. The air-cooling system requires no consumables, and the integrated modular machine structure minimizes routine maintenance needs. With an extremely low failure rate, the machine is well-suited for 24/7 continuous production environments.
③ Automation Integration Capability
The machine features expandable I/O signal interfaces (input/output), enabling seamless integration with robotic loaders/unloaders, conveyor systems, vision inspection equipment, and other peripherals. This allows the GW-DLS01 to be embedded into fully automated production lines, raising the overall automation level of the factory floor.
④ Optional Fume Purification System
Vaporization of insulating coatings during processing generates small amounts of organic fumes. An optional high-efficiency fume purifier can be added to protect the laser focusing optics from contamination (extending optical component lifespan) and to eliminate odors, safeguarding workshop air quality and operator health.
⑤ Compact, Integrated Structure
The machine body uses a rigid monolithic frame design with a built-in industrial PC. Its compact footprint makes it suitable for cleanroom environments, precision workshops, and other space-constrained production settings, while also enabling stable operation under demanding industrial conditions.
