Clean maintenance is needed before assembling mechanical and electronic products and during the procedure, including cleaning specific materials or components. Traditional mechanical friction cleaning, chemical erosion cleaning, vigorous effect cleaning, and high-frequency ultrasonic cleaning are timeless without mechanization and negatively impact the atmosphere. At the same time, there is no responsible mode to estimate the impact of cleaning.
In contrast, laser cleaning has the benefits of no consumables, no pollution, low expense, high efficiency, no touch, no stress, no damage, good controllability, optional clean area, and the capacity to clean dangerous zones. It is regarded as the most dependable and helpful solution to future cleaning issues.
What is a laser cleaning machine, and how does it work?
Laser cleaning machine is an eco-friendly cleaning tool that uses a nanosecond or picosecond vibrating laser to illuminate the workpiece surface. The surface of the workpiece immediately immerses concentrated laser energy to multiply growing plasma (highly ionized, oily, gaseous). Evaporation or peeling of coating, dust, and oxide layer or film to remove surface extension efficiently.
The laser cleaning machine usually consists of a laser, an automatic control operating system, a beam transmission shaping unit, a cleaning quality detection and protection unit, and a displacement platform.
Applications of Laser Cleaning Machine
Applicable Materials
In industrial applications, laser cleaning materials are separated into substrate and cleaning materials. The substrate consists primarily of surface impurities of various metals, ceramics, magnetic materials, semiconductor wafers, plastics, and optical components. Cleaning materials are primarily used in industrial face, paint removal, rust removal, oil removal, film/oxidation removal, resin, glue, dust, and slag dumping.
Applicable Industries
Investigation into laser cleaning technology started in the mid-1980s but didn’t enter industrial production until the early 1990s. It has reached sound effects in applying mold cleaning, material surface remedy, large-size tools, accuracy machining, etc.
Also, European countries usually possess many historical remembrances and ancient buildings. Many castles, churches, universities, museums, sculptures, etc., have hundreds or thousands of years of yore. Europeans have spent close attention to keeping and repairing these “antiques.” Laser cleaning technology has been exploited to heal and decontaminate artistic defaults.
Microelectronics field
Material pins for releasing particles and oxides for microelectronic devices, semiconductor elements, silicon templates, memory templates, etc.
Cultural Relic
Safety gravel carvings, glass, paper, oil paintings, bronze, sheepskin scrolls, murals, etc.
Clean the mold
Metal molds, rubber molds, compound molds, etc.
Surface Treatment
It is used in surface roughing, hydrophilic treatments, and pre-treatment before welding.
Others
Cleaning urban graffiti, precision machining of industrial parts, exterior walls, nuclear pipelines, printing rollers, and other hazardous industries.
Why is laser cleaning an intelligent choice?
The laser cleaning solution is the most suitable method to scrub the surface. Laser cleaning is deemed environmentally friendly as there is no use of chemical vendors and cleaning fluids like the conventional way. The traditional cleaning process is the kind of reference that can hurt the object, resulting in improper cleaning when laser cleaning is a non-contact solution. Moreover, the laser can contact the hard part, traditionally incomprehensible.
Therefore, the laser can assure the security of workers when used in hazardous areas. Furthermore, laser cleaning performs cleanliness by removing various contaminants that conventional methods cannot achieve from the surface. Of course, laser cleaning can draw traditional abrasives and is an alternative to chemical processes in heavy industries such as aerospace and shipbuilding. The coating removal method can be made more frugal by using laser solutions. So laser cleaning is a wise option.
