Laser Cleaning Machines Application In Industry

December 12, 2023

Laser cleaning machine is a cleaning method that uses nanosecond or picosecond pulsed laser to irradiate the surface of a workpiece cleaned, causing the workpiece surface to instantly absorb focused laser energy, forming a rapidly expanding plasma (highly ionized unstable gas), causing oil stains, rust spots, dust, coatings, oxide layers or film layers on the surface to vaporize or peel off, thereby efficiently removing surface attachments.

In the industrial application field, laser cleaning machine objects are divided into two parts: substrate and cleaning material. The substrate mainly includes surface pollution layers of various metals, semiconductor chips, ceramics, magnetic materials, plastics, and optical components. The cleaning material mainly includes a wide range of application requirements for industrial fields such as rust removal, paint removal, oil removal, film/oxide layer removal, and resin, adhesive, and dust residue cleaning.


At present, the widely used cleaning methods in the cleaning industry include mechanical cleaning, chemical cleaning, and ultrasonic cleaning. However, due to environmental protection constraints and high precision market requirements, their application is greatly limited. Laser cleaning machines have obvious advantages in various industries.

1. Laser cleaning machines can be integrated with CNC machine tools or robots to implement remote control and cleaning, achieving equipment automation, forming product assembly lines, and intelligent operation.

2. Using fiber optic transmission to guide the laser, it has the flexibility to control the high-speed movement of the light spot through a built-in scanning galvanometer, which facilitates non-contact laser cleaning of corners, holes, grooves, and other parts that are difficult to reach by traditional cleaning methods.

3. Short-term impact does not heat the metal surface and does not damage the substrate.

4. The pulse laser used in the laser cleaning machine has an ultra-long service life, usually up to 100000 hours, stable quality, and good reliability.

5 No chemical cleaning agents are required and no cleaning waste is generated. The pollutant particles and gases generated during laser cleaning can be simply collected and purified through a portable exhaust fan, avoiding environmental pollution.

6. During the use of the laser cleaning machine, there is no consumption of consumables, and the operating cost is low. In the later stage, only regular cleaning or replacement of the lenses is required, resulting in low maintenance costs and close to maintenance-free.

Typical applications of laser cleaning include mold cleaning, industrial rust removal, removal of old paint and film layers, pre-welding and post-welding treatment, ester removal of precision parts, decontamination and oxidation layer removal of electronic components, cultural relic cleaning, etc. Widely used in industries such as metallurgy, molds, automobiles, hardware tools, transportation, construction appliances, machinery, etc.
