Pulsed laser energy can be used to remove contaminants or other unwanted layers without damaging the underlying surface. A focused laser’s high energy density and its ability to be directed into precise and controlled areas make it a great tool for cleaning a variety of surfaces. The applications for laser cleaning are endless and span many industries such as aerospace, automotive, medical, construction, food, and many more.
Examples of laser cleaning applications include:
• Rust removal
• Mold cleaning
• Paint stripping
• Baking plate cleaning
• Heat Seal Die cleaning
• Art or antique restoration
• and many more…
Advantages of Laser Cleaning:
• Precise Cleaning Area– small spot size of focused laser energy allows for fine control of cleaning locations.
• Non-Contact – no mechanical contact to cause unnecessary wear.
• No Consumables – laser cleaning eliminates the need for consumables such as chemicals or replacement cleaning tools.
• Flexible Integration – Laser cleaning systems can stand alone or be integrated into a production line.
Method of Laser Cleaning:
Laser energy is focused onto the part and steered through the cleaning area using a galvanometer. The high energy density beam reacts with the surface to remove the unwanted coating or layer. The laser cleaning process works most efficiently when the substance being removed has high absorption in a specific wavelength range of laser energy and the underlying substrate is reflective in this same range. This relative difference of absorption causes the unwanted material to heat up quickly and ablate from the surface leaving the substrate unaffected. A fume extraction system is used in conjunction with the laser to remove the airborne ablated material in a clean and controlled manner.
Near infrared wavelengths are most commonly used for laser cleaning but depending on the absorption properties of your materials a different wavelength may be more efficient.
