MOPA Handheld Portable Laser Rust Removal Machine

Laser cleaning machine is an automatic equipment that releases high-energy pulsed laser beam to irradiate and remove the rust, dust, contaminant, painting and oxide on the surface of the work piece. The principle of laser cleaning technology is that the contaminants on the surface of the work piece melt or evaporate instantly after being irradiated by the pulsed laser beam, so that the surface of the work piece becomes clean. Laser cleaning is efficient and eco-friendly. It is becoming more and more popular in various industries.

The efficient laser cleaning lies in the fiber laser generator which releases high-density fiber laser beam. Traditional industrial cleaning methods usually use chemical reagents or mechanical methods to remove the contaminants on the surface of the work piece. These methods have some disadvantages, such as low efficiency, damage the substrate or generate additional contaminants. Moreover, with the increasingly strict environmental protection laws, there are fewer chemicals that can be used in the industrial cleaning. Therefore, looking for an eco-friendly cleaning method is a major problem for many companies.

The table below is a comparison of various cleaning methods. Compared with the traditional mechanical cleaning method, chemical cleaning method and ultrasonic cleaning method, laser cleaning does not require any organic solvents and is pollution-free. The laser cleaning process has no noise and no damage to human body and environment.

Laser cleaning machine uses laser ablation principle to remove the dust on the metal surface. Laser ablation is a type of physical reaction. When the high-density laser beam irradiates on the metal surface, it is absorbed by the pollution layer on the metal surface. The absorption of large energy forms a rapidly expanding plasma which generates shock waves, and the shock waves turn the pollutants into fragments and remove them off the metal surface. The laser ablation reaction occurs in this way and makes the rust, dirt and oxide layer melt and evaporate very quickly.

Different materials have different properties, so each material has a specific ablation threshold. As long as the energy of laser beam is above the ablation threshold of the dust that needs to be removed, the laser beam can successfully remove the dust. The ablation threshold of rust, oil or painting is much lower than metals like stainless steel, carbon steel, aluminum, etc. Therefore, if the laser parameters are set reasonably, the laser cleaning process will not damage the substrate and leave a very clean surface.

As the laser cleaning machine uses laser ablation to remove dust, there is no consumables required during the laser cleaning process. The traditional industrial cleaning methods like chemical cleaning, ultrasonic cleaning or dry ice cleaning need cleaning reagent to finish the cleaning process, which improves the processing cost and labor cost. Laser cleaning method solves the problem perfectly and it is pollution-free. More and more enterprises prefer use the laser cleaning machine to clean metal parts and restore equipment surface.

More and more companies and individuals want to buy a laser cleaning machine to support their business. How to buy a suitable laser cleaning machine that fits your needs? You can follow the below three steps.

1. First of all, contact with a qualified manufacturer that has profound experience in the manufacturing of laser cleaning machines. A reliable manufacturer not only produces high quality laser cleaning machines, but also provides you complete machine data and thoughtful after-sales service. Before you buy a machine, it is essential to inspect the factory and check the real cleaning effect of the machine.
2. In addition, check the machine’s appearance. The design, structure and manufacturing process can almost directly determine the quality of the machine. The design style of each manufacturer is different. A manufacturer that has mature production technology always continuously improve the machine’s appearanceand structure under the premise of ensuring quality.
3. Choose the machine according to your needs and budget. Tell the salesperson about your cleaning requirements and budget plan, and they will recommend the suitable machine and configure the parameters, machine size and parts. Let the salesperson know your detailed processing requirement (processing materials, cleaning speed, etc.) so that you can get a most cost-effective laser cleaning machine.

Laser cleaning machine has the characteristics of non-contact, no thermal effect, no mechanical force on metal surface, no consumables and low processing cost. This machine has been widely used in many industries. So how to use a laser cleaning machine after you buy one? Here are the main steps for your reference. Please always remember that you need to read the operation brochure provided by the manufacturer to understand the precautions and operation instructions. Wear protective glasses and other protective equipment to ensure your safety. And do not look directly at the laser output position with you eyes during the cleaning. Check the machine parts and make sure nothing is damaged or missing, and no dust or dirt on the machine.

1. Check the power supply of the machine and make sure it is grounded.
2. After checking the machine, insert the plug into the power socket. Turn on power switch and set parameters on the control panel.
3. Take out the cleaning gun and open the cover, aim the gun head at the work piece that you need to clean and start your cleaning work.
4. After the cleaning process, release the gun button, turn off the laser switch, turn off the power, insert the cleaning gun back into the storage box, and then unplug the power plug.
5. If you encounter any problems during the operation, please seek help from after-sales engineer and do not disassemble the machine by yourself. Unauthorized disassembly and assembly may damage the machine or bring danger to the operator.
