Different Types of Laser Cleaner
The laser cleaner is a non-contact, no-scratch, chemical-free method of cleaning surfaces.laser cleaner It uses high-intensity laser beams to vaporize paint, rust and other unwanted materials from surface coatings without damaging the underlying substrate. This process is remarkably fast and easy compared to traditional cleaning methods such as sand blasting, water jet cutting or chemical solvents. The laser beam can be precisely aimed using an optical fibre to target only the desired surface material. This allows for precise control of ablation thresholds on the surface, removing the layer with micrometre levels of accuracy. Laser cleaning is conducted in person, using a handheld system to move the laser beam over the workpiece, or remotely, by robots operating within a controlled laser safety enclosure.
The most common laser systems used for this purpose are nanosecond pulsed, diode pumped fibre lasers in the near-infrared spectrum.laser cleaner These are capable of delivering laser power from tens of watts to multiple kilowatts and can be configured for handheld, automated or robotic applications. Their short pulse duration minimises heat-effect on the underlying substrate and repetition rate can be adjusted for optimum processing speed.
Handheld laser cleaners are perfect for small, confined areas and delicate historic surfaces that need to be treated gently.laser cleaner They use a single hand-held gun to position the laser head and can be moved around a workpiece with ease. Different laser configurations can be manually selected for a range of contaminants, substrates and thicknesses. This versatility makes them ideal for a variety of industrial applications such as:
These systems are designed for reliability and minimal maintenance with no other media required to treat parts.laser cleaner They offer simple operation, quick set-up and a fast return on investment. They are also surprisingly portable and are easy to move and can be easily integrated into automated production environments.
For large surface treatments, lasers are positioned on a mobile system and can be operated either in person or remotely. For the latter, a suitable fume extraction system is needed to ensure that no harmful particulates are released into the surrounding environment. This is because the laser vaporises the surface coatings into gaseous particles.
Laser surface preparation for joining or bonding processes, coating removal and metal surface treatment are the primary applications of this powerful technology. For example, the automotive industry employs it for phosphate removal of bevel gears before welding to ensure less spatter and pores; and in the aviation and maritime industries, it is used for bonding pre-treatment and coating removal of aluminium components. It is even used to clean tyre moulds and tooling in order to prevent contamination during assembly and to strip aluminium panels and propellors before painting. The laser cleaner is the ideal solution for a wide range of surface preparation, coating removal and metal surface treatment applications. This is because it offers a safe, environmentally friendly alternative to traditional mechanical and chemical surface treatment techniques.
