Laser cleaning refers to surface cleaning using a fiber optic laser. The same fiber optic laser is used in metal cutters, laser markers and engravers. Thus, a laser-cleaning machine is suitable for removing rust from metal items and workpieces. Operation of laser cleaning is based on exposing a light beam to the surface. If there are no contaminations (for example rust), the laser beam is reflected. If there is corrosion, it absorbs the beam. Because of thermal energy of the laser, the strength of metal oxide molecules that form the rust decreases. They collapse, detach from the metal, melt, and evaporate.
Advantages of Laser Cleaning Machine
Selective cleaning
Laser cleaning can target the contaminant layer that requires removal. The underlying material will always be unharmed by the process.
Consumable free
There are no solvents or chemicals required for laser cleaning. It is a completely consumable-free process.
Versatile
Laser cleaning is a very versatile process. It can apply to all types of materials. The important thing is to know the ablation threshold.
Speed
Laser cleaning is a high-speed process. There is no drying time or waiting period, unlike chemical cleaning. Additionally, the speed of high power lasers can clean any material within seconds.
High-quality results
Laser cleaning efficiently cleans the surface, providing a very high quality surface finish.
Material integrity
The material integrity remains preserved in laser cleaning. This is because the laser only interacts with the contaminant, and its energy is too low to harm the underlying metal.

Types of Laser Cleaning Machines
Handheld laser cleanerHandheld laser cleaning systems are workstations on wheels. They’re larger than what most people expect of a handheld device, but they’re still easy to move around. The “gun” held by the operator can be positioned as needed to reach any area on large workpieces. These devices are ideal for low-volume productions where multiple parts of different shapes and sizes need to be processed.
Handheld laser cleaners come with laser configurations that can be manually selected for specific tasks, such as laser rust removal, paint removal, and corrosion removal. As with all types of laser cleaners, different configurations are needed for different contaminants, thicknesses, and substrates.
Laser cleaning workstations can be fully operated manually while being 100% safe for operators without PPE. Operators are responsible for loading parts into the machine and triggering the laser process. They may also need to perform other tasks depending on the type of workstation, such as opening the door, triggering table rotations, and managing fixtures.
Manual workstations can be equipped with a rotary table to meet high throughput requirements. They can be installed directly in the production line or offline.
Conveyor Cleaning MachineLaser cleaners can be installed directly on conveyors to automate contaminant removal and surface texturing before operations like welding or coating, providing complete surface preparation in a single step. Advanced features can be used to automatically manage inconsistencies in part positioning as well as process large parts with several areas that need to be cleaned.
These machines are especially useful in the automotive industry where many parts are moved from one production step to another using conveyors, such as in battery production lines. Conveyor laser cleaning machines are adjusted to fit the conveyor dimensions.
Laser cleaning systems can be mounted on robots to automate cleaning operations in robotic cells. They are equipped with advanced autofocusing systems to clean complex parts with high precision. The robot’s high freedom of movement allows the laser to clean various shapes with simple, automatic adjustments.
Robot cleaning machines can also be used to automate the cleaning of large surfaces when mounted with an ultra-high-power laser.
Fiber Laser MarkerThe difference between a laser cleaning system and a laser cleaning machine isn’t always clear. Laser cleaning systems are OEM devices that can be integrated into fully custom solutions, typically with the help of a system integrator or machine builder. Laser cleaning machines, on the other hand, are predesigned solutions ready to be integrated in production lines.
All materials have an ablation threshold
Laser ablation occurs when a material layer or a coating is removed with a laser beam. This is the process behind all laser cleaning applications. Take laser rust removal on steel. When the beam hits the surface, molecular bonds in the dust or rust layer are broken and ejected from the substrate. In less technical terms, you can imagine that the layer to be removed is simply vaporized by the laser beam.
It is possible to remove a material in a highly selective way
Let's continue with our analogy. Imagine there was a second, higher wall behind the first one and that a ball was thrown with just enough energy to make it over the first wall, but not enough to make it over the second. The ball would bounce off the second wall and fall in between the two walls. Once again, no matter how many times you throw the ball, you will always get the same result. You will make it past the first wall but never the second.
A strong and short power burst means faster removal
You can think of laser ablation as similar to carving stone with a hammer and a chisel. You can use a small hammer and do many small hits on your chisel. Or, you could just as well use a bigger hammer to leverage more power, hence reducing the required number of hits and increasing the removal speed. The idea is the same with laser cleaning, except that you only want to remove a layer of material: The contaminant.
It is consumable-free and environmentally friendly
As this cleaning method only uses a laser beam to vaporize the layer to be removed, there are literally no consumables with it. This is the beauty of lasers, which only need a power plug to be set and ready to go.
Laser cleaning is of interest for various industrial applications
Removing the burnt rubber residue from tire molds; giving a new life to old pipelines; cleaning pipes in nuclear power plants; and even larger projects such as removing paint from a rusty bridge and preparing welding surfaces are all projects that can benefit from industrial laser cleaning. This non-contact cleaning technique can be used in countless industrial applications. The only limit is the capacity to discriminate between the material to be removed and the one to be protected.
Laser cleaners are used to clean a lot of different unwanted particles from metal surfaces. Some common examples are:
Rust
Laser rust removal is one of the most common laser cleaning applications. Lasers can remove corrosion contamination on all types of metal surfaces.
Paint
Laser cleaning is a great way to remove paint when repainting surfaces. Chemical cleaning of paint is often degrading for the underlying metal.
Grease and Oil
Grease and oil contaminant removal is a common requirement for all types of surfaces. Laser surface cleaning can clean these materials in a no-contact process.
Dirt
Dirt accumulation takes place on all surfaces. Laser cleaning removes dirt particles without requiring manual dusting or wiping.
Adhesive Bonding
Adhesive bonding residue is difficult to remove without chemical products. Laser cleaning is the best process to remove adhesive bonding without chemical products.
Historical Artifacts
Historical artifacts are sensitive to damage. Laser cleaning provides the extreme care to clean these pieces without damaging them.
PCBs
Electronic parts like PCBs are sensitive to fluids due to electrical faults they can create. Laser is a great way to clean electronic components without causing electrical failure.
Industry Using Laser Cleaning Machine
Auto industry
Laser cleaning is mainly used in the automotive industry to manufacture steel surface contours and rust removal. Rust and scale are pollutants formed on the metal surface due to natural or artificial processes. This rust will reduce the quality of the metal and make it not applicable to various applications.
Laser cleaning can remove these unwanted surface sediments to provide smooth surfaces for pre-processing and fine-processing technology such as electroplating. After the laser is transmitted in a short pulse, the rust will quickly absorb the energy of the laser beam, resulting in a temperature rise. Once the temperature is high enough, the iron rust melts and eventually evaporates. Before the application of the protective coating to manufactured steel parts for anti-corrosion and protection, their surface must be cleaned without any pollutants.
Aerospace and airlines
Powerful laser cleaning is the preferred method for tin welding or pre-welding pollutants, metal mold residues, and metal abandoned. Traditional rust removal and dirt removal methods cannot meet the needs of the aerospace industry with precision and speed, but the use of laser cleaning machines can be quickly done. It can better control power, wavelength, and pulse duration, and evaporate in rust/scale evaporation later, a laser will not cause any damage to the underlying material.
Medical industry
Laser cleaning plays a vital role in medical technology for the precise pretreatment of stainless steel components. It removes unwanted contaminants without affecting the base material and without exposing any gases that are harmful to humans. So it has a safe sterilization ability, is designed to easily clean any angle and detail, and only needs to repeat the operation to achieve the desired degree of cleaning. Repeated operations reach the degree of cleaning required. The flexibility of the laser cleaning machine helps it to use it in more new applications.
Industrial industry
Laser is also used for many industrial cleaning of the machinery industry, electronics industry, rubber, and nuclear purification. In the rubber industry, it is often used for cleaning aluminum molds. If you need to clean the rubber mold, the cleaning speed will be a decisive factor. Taking the tire mold of a passenger car as an example, if it is cleaned by sandblasting or chemical cleaning traditionally, it takes about eight hours of manual labor. Using a laser cleaning system can clean 2 square meters per hour, which is a huge improvement.
Safety is the number one consideration for laser cleaners. Laser cleaning involves the use of high-energy laser beams, which can be dangerous if not managed properly. There are three guarantees for the safe and correct operation of laser cleaning machines:
Self-safety and environmental protection
Laser cleaning machines have adequate safety features on their own. High-powered machines are typically equipped with safety features such as enclosed workspaces, interlocks, and safety sensors to keep operators and bystanders safe from potential laser hazards. Compared to traditional cleaning methods such as mechanical and chemical alternatives. Our laser solutions do not produce additional waste to reduce the impact on the environment.
Reasonable security measures
Laser cleaning is less of a safety risk. Most portable laser cleaning machines are small in size, low in power, and relatively safe; when using a high-power laser cleaning machine, pay attention to staying away from designated dangerous areas, and the operator should be equipped with necessary safety protection equipment, including laser protective glasses and gloves, avoid danger.
Effective operations training
Learn how to use cleaning technology safely and correctly through training. In order to operate the machine safely, we will conduct related training for laser cleaning machine operations -including safety precautions, equipment operation, maintenance skills and correct fault exclusion strategies, and which settings are most suitable for your specific cleaning needs. In this way, you can get the most effective cleaning without damaging structure.
Our laser solutions are considered one of the safest and most effective applications of clean forms. However, the wrong use of a laser will not only be dangerous to your products but even waste a lot of time and money on invalid things.
How To Improve The Life Expectancy Of Laser Cleaning Machines
Regular cleaning and maintenance
Regularly clean and inspect optical components such as lenses and mirrors to prevent the accumulation of contaminants that could affect laser generator performance. Lubricate moving parts according to the manufacturer’s specifications to reduce friction and wear. Check the machine for loose or damaged parts and resolve any problems promptly. Use appropriate tools and detergents when cleaning to prevent scratches and corrosion.
Environmental control
Maintain a clean and controlled environment for the laser cleaning machine. Prevent overheating and contamination by controlling temperature, humidity, and ventilation. Implement effective dust and particle control measures to minimize the accumulation of contaminants on optical components.
Operator training
Properly train operators to ensure they understand the correct operating methods and safe operating procedures of laser cleaning machines. Improper operation may cause excessive wear or damage to the equipment.
