Affordable laser cleaning & rust removal machines for sale

What is laser cleaning technology?

Laser cleaning technology refers to using high-frequency, high-energy laser pulses to irradiate the surface of the workpiece. The coating layer can instantly absorb the focused laser energy, causing the oil, rust or coating on the surface to evaporate or peel off instantly and quickly and effectively remove surface attachments or surface coatings. The laser pulses with very short action time will not damage the metal substrate under appropriate parameters.

How does the laser cleaning machine perform cleaning work?

The laser cleaning process can be divided into the following steps:

(1) Laser emission: The laser cleaning machine first generates a beam of high-energy laser, usually emitted by a pulsed laser or a continuous wave laser.

(2) Laser focusing: After the optical system focuses the laser beam, it forms a small and energy-intensive light spot, which directly acts on the object’s surface to be cleaned.

(3) Energy transfer: When the laser spot contacts the surface of the object to be cleaned, the energy is quickly transferred to the dirt, causing it to absorb a large amount of heat in a short period of time.

(4) Dirt removal: After the dirt absorbs heat, it quickly heats up and undergoes physical or chemical changes, such as melting, vaporization, cracking, etc., and eventually falls off the object’s surface or is blown away.

(5) Surface cleaning: As the laser beam moves, the dirt on the object’s surface to be cleaned is removed one by one, and the surface is finally cleaned.

What can laser cleaning machines clean?

A laser cleaning machine is a multi-purpose cleaning equipment. It can clean the surface of metal or non-metal parts. When processing the corresponding workpiece, you only need to adjust the interface parameters of the laser cleaning machine. The laser cleaning machine can clean the following things:

1. Remove the coating on the metal or glass surface and quickly remove the paint;

2. Quickly remove rust and various oxides;

3 Remove grease, resin, glue, dust, stains and production residues;

4 Roughen the metal surface;

It can play an essential role in cleaning and removing chewing gum residues.

What are the advantages of laser cleaning machines over traditional cleaning machines?

Laser cleaning has the characteristics of no grinding, no contact, and no heat effect and is suitable for objects of various materials. It is considered to be the most reliable and effective solution. At the same time, laser cleaning can solve problems that traditional cleaning methods cannot. Laser cleaning technology has advantages that conventional methods cannot match. With the continuous improvement of technology and the mass production of equipment, laser cleaning technology will play an essential role in the cleaning industry.

Compared with traditional cleaning methods such as mechanical friction cleaning, chemical corrosion cleaning, liquid, solid vigorous impact cleaning, and high-frequency ultrasonic cleaning, laser cleaning has the following six apparent advantages:

1. Green cleaning: No chemical agents are used, and the waste after cleaning is solid, harmless powder, which can completely solve the environmental pollution problem caused by chemical cleaning. Often, an exhaust fan can solve the waste problem generated by cleaning.

2. Non-damage cleaning: Laser cleaning is non-grinding, non-contact, and has no heat effect. It will not produce mechanical force on the cleaned object, damage the surface of the object, damage the substrate, or cause secondary pollution.

3. Low-cost cleaning: The initial investment in the laser cleaning system is high, but it can be used steadily for a long time, with a service life of up to 10 years. It has low operating costs, fast speed, high efficiency, and time savings, and can quickly return on investment. In the long run, the cost is lower than traditional cleaning methods.

4. Convenient advantage: The laser cleaning machine can remove various types of pollutants from the surface of multiple materials, achieving cleanliness that cannot be achieved by conventional cleaning. It can also selectively clean contaminants without damaging the surface of the material.

5. Precision advantage: It can effectively clean micron-level polluted particles and achieve controllable fine cleaning, suitable for cleaning precision instruments and parts.

6. Automated cleaning: Lasers can be transmitted through optical fibers and cooperate with robots to achieve long-distance operation. They can clean complex structural parts that are difficult to reach by traditional methods. This feature also makes the safety of operators in some dangerous places more secure and can be equipped with automated equipment to achieve automated cleaning.
