Multi-Power Water-Cooled Cabinet-Type Pulsed Laser Cleaning Machine

The cabinet-type pulsed laser cleaning machine is an industrial-grade surface treatment system integrating a water-cooling heat dissipation system and a unified cabinet structure. It uses a pulsed fiber laser as the core light source, relying on nanosecond-level high-energy pulses to achieve pollutant vaporization and stripping. The process requires no consumables, no chemical agents, and causes zero thermal damage to the substrate. It supports both flexible handheld operation and automated production line integration, making it a green alternative to traditional cleaning processes such as acid pickling, sandblasting, and grinding.

This machine uniformly adopts a 1060–1080nm fiber pulsed laser, equipped with a standard water-cooling constant-temperature system, and is adaptable to workshop environments ranging from 0°C to 40°C. The pulse width is adjustable from 30 to 500 ns, frequency from 1 to 1000 kHz, with full parameter adjustability. The scanning range covers 0–100 mm, supporting 8 scanning patterns. The standard armored cable length is 10 meters and can be extended upon request. The power supply is compatible with universal AC110/220V industrial voltages, with a maximum total power consumption ≤ 2200W.

Based on laser output power, the product line is divided into three categories: the 300W precision model, the 500W general industrial model, and the 1000W heavy-duty high-efficiency model. The three models share the same hardware architecture, but differ significantly in pulse energy, cleaning efficiency, and applicable working conditions. They can meet the full range of application scenarios, from precision micromachining, batch component processing, to large-structure rust and paint removal.

II. Detailed Comparison of the Three Types of Cabinet-Type Pulsed Laser Cleaning Machines

(1) 300W Water-Cooled Cabinet-Type Pulsed Laser Cleaning Machine (Precision Model)

Maximum pulse energy: 15 mJ. Low peak energy output ensures an extremely small heat-affected zone. The water-cooling constant-temperature system provides stable temperature control, making it suitable for long-duration, high-precision, fine-scale operations.

Core Advantages

Controllable and gentle energy output, completely eliminating substrate ablation or deformation when dealing with thin coatings, slight oxidation layers, and precision microstructures.

Low overall power consumption and very low operating costs; finely adjustable parameters allow processing of micron-level precision workpieces.

Lightweight handheld operation, and can also be mounted on small robotic arms, suitable for cleaning narrow cavities and small parts in automated setups.

Applicable Contaminants

Slight rust, thin oil films, thin paint layers, oxide scale on electronic components, resin residue on molds, slight black soot on weld seams.

Application Scenarios

Precision sample cleaning in laboratories, routine maintenance of injection molds, pre-weld oxide removal for aviation small parts, surface contamination cleaning on circuit boards, and batch precision finishing of small hardware parts.

(2) 500W Water-Cooled Cabinet-Type Pulsed Laser Cleaning Machine (General-Purpose All-Rounder)

Maximum pulse energy: 50 mJ. Balances peak energy with cleaning precision. The water-cooling system supports long-duration continuous industrial operation, making it the most popular model on the market.

Core Advantages

Significantly improved contaminant removal capacity, with cleaning speed twice that of the 300W model; medium-thickness rust layers and multi-layer paint can be stripped in a single pass.

Balances precision and efficiency; compatible with carbon steel, aluminum, copper, stainless steel, and rubber molds, offering the broadest versatility.

High compatibility with automation integration; can be connected to six-axis robotic arms on assembly lines, suitable for medium-batch continuous production.

Strong environmental adaptability; operates stably in both workshop and semi-open workstations, with low failure rates.

Applicable Contaminants

Moderate rust, heavy oil stains, multi-layer industrial coatings, large-area black soot on weld seams, rubber release residue, surface graffiti on equipment, light rust on marine parts.

Application Scenarios

Pre-weld pretreatment for automotive body parts, rust removal and refurbishment of rail fittings, deep cleaning of mold carbon deposits, paint removal on aluminum alloy sheets, and rust removal in batch hardware production lines.

(3) 1000W Water-Cooled Cabinet-Type Pulsed Laser Cleaning Machine (Heavy-Duty High-Efficiency Model)

High average power combined with 50 mJ pulse energy and high pulse frequency output. The enhanced water-cooling system supports all-day, uninterrupted heavy-duty cleaning operations.

Core Advantages

Doubled cleaning efficiency; processing speed for large-area components is far higher than that of the 300W and 500W models, significantly reducing production time.

Capable of stripping heavy rust, thick anti-corrosion paints, and multi-layer aged coatings; stubborn, heavy contaminants can be removed without repeated passes.

The cabinet's water-cooling heat dissipation provides ample capacity, ensuring no power degradation due to temperature rise even under prolonged full-load operation.

Long-armored cables are suitable for on-site outdoor operations on large ship hulls, complete vehicles, and large machine tools.

Applicable Contaminants

Heavy rust, thick industrial anti-corrosion paints, large-area oxidation layers, deck coatings on ships, cured dirt on heavy equipment, and multi-layer aged coatings on old components.

Application Scenarios

Rust and paint removal on ship hulls, refurbishment of train carriages, pretreatment of large steel bridge structures, complete cleaning of heavy machine tools, and overall refurbishment of large injection molds.

III. Common Core Features of Cabinet-Type Pulsed Laser Cleaning Machines (Applicable to All Models)

Water-Cooled Constant-Temperature Stabilization System

The complete machine is equipped with an independent water chiller capable of active heating and cooling, maintaining the laser source at its optimum operating temperature. It supports long-term continuous operation in high- and low-temperature workshop environments without power attenuation. Compared to air-cooled models, the continuous operation duration is increased by more than three times.

Non-Damaging Precision Cleaning

The pulsed laser action time is only on the nanosecond scale, resulting in extremely low thermal effects. By adjusting pulse width, frequency, and energy to suit different substrates, the workpiece dimensions, hardness, and flatness remain unchanged after cleaning. Thin aluminum, thin plates, and precision electronic parts can all be safely processed.

Green and Low-Cost Operation

No need for chemical consumables such as hydrochloric acid or degreasers, and no wastewater or gas emissions. The stripped rust and paint debris can be collected centrally as solid waste. The system consumes only electrical power, with no easily worn consumables, making long-term operating costs far lower than sandblasting or acid pickling.

Dual-Mode Flexible Operation

Supports handheld gun manual localized cleaning, or fixed laser scanning heads connected to robotic arms and automated production lines. It can reach areas that are difficult for traditional processes, such as internal pipe cavities, weld seam死角, and complex curved surfaces. High-risk conditions can be handled via remote automated operation to ensure personnel safety.

Wide Adjustable Scanning System

Stepless adjustment of scanning range from 0 to 100 mm, with dual-axis 8 scanning patterns (line, spiral, sine wave, etc.). Interchangeable with multiple field lenses of 160, 210, 300, and 420 mm specifications, suitable for both fixed-point cleaning of small parts and rapid processing of large flat components.
