This kind of metal rust or dirt not only affects the appearance of the machine, but also affects the operating efficiency of the machine, causing damage to the machine, resulting in a significant reduction in productivity. Therefore, laser cleaning machines are widely used in the existing industrial field. If you have the above troubles and want to buy a laser cleaning machine for rust removal, please read this article carefully, it will be very helpful to you.
What Is a Laser Cleaning Machine and How Does It Work？
Presumably, your initial understanding of laser cleaning machine is that they are machines used to clean dirt and rust. Yes, you are right. Laser cleaning is a new high-tech technology used in cleaning and rust removal. Laser cleaning machines use the high energy and high density characteristics of lasers to enable lasers to clean the surface of the cleaning target, thereby achieving the effect of rust removal or decontamination. Similarly, the principle of laser cleaning machines is to use the laser beam under instantaneous high energy irradiation to break the rust and dirt on the target surface and peel off the surface of the object, thereby achieving the cleaning of the surface of the object.
Application and Advantages of Laser Rust Removal Machine
Laser rust removal machines are widely used in the automotive industry, aerospace, electronic equipment, building maintenance and other fields. Compared with traditional cleaning methods, laser cleaning is cleaner and more environmentally friendly, with lower energy consumption and less waste. At the same time, laser rust removal machines do not use any chemical agents for cleaning. This environmentally friendly cleaning method can reduce environmental pollution and create green production. Laser rust removal machines
Electronics Industry: First of all, the electronics industry has very high requirements for purification accuracy. Using laser rust removal to remove oxides can ensure the accuracy of electronic products to the greatest extent to ensure the best electrical contact.
Building Maintenance: Whether it is contemporary or ancient buildings, external cleaning and maintenance is an indispensable task. Contemporary buildings are generally high in height. Using traditional cleaning methods is extremely inefficient and there are great safety hazards. Using a laser cleaning machine for cleaning has greatly improved the production efficiency of cleaning. The 70-meter optical fiber of the laser cleaning machine can solve the problem of safety hazards very well. For the appearance of ancient buildings, the maintenance difficulty is relatively high. For some rust stains or stains that are difficult to clean, manual cleaning that is less difficult to destroy has little effect. Using chemical detergents for cleaning will even destroy the integrity of ancient buildings. The laser rust removal machine perfectly solves this problem, effectively cleaning stains on stone and metal, and retaining the appearance of ancient buildings to the greatest extent.
Mold Cleaning: Traditional methods for cleaning molds include ultrasonic, chemical detergent or carbon dioxide cleaning. The traditional chemical detergent cleaning method requires heating and cooling before cleaning. The process is complicated, time-consuming and labor-intensive, and it will also harm the environment. Using a laser cleaning machine for cleaning will cause little damage to the mold and will not produce toxic gases, which is also a protection for employees.
Aerospace Field: The aerospace field is mainly used for painting on the surface of aircraft. The old paint needs to be cleaned before painting. Using traditional tools for mechanical processing is very likely to cause damage to the aircraft, posing a very large safety hazard to the aircraft flight. Using a laser rust removal machine for cleaning is the most ideal choice. The paint layer on the surface of the aircraft can be thoroughly cleaned within 2 days without damaging the surface of the aircraft.
Automobile Industry: The traditional cleaning method for cleaning precision parts required for automobile manufacturing is chemical cleaning, but the disadvantage of chemical cleaning is that it will still cause a certain degree of damage to precision parts. Laser cleaning is a non-contact cleaning method that will not cause subtle damage to parts, thus ensuring the safety of automobile production.
Long-term Cost-effectiveness of Laser Cleaning Machine
The long-term cost-effectiveness of laser cleaning machines depends on a variety of factors, such as substrate, equipment size, intensity and frequency. In the long run, laser cleaning systems will be more economical. Because they are less energy-efficient, they require less chemical cleaning agents. In addition, the labor and maintenance costs required for laser cleaning machines are relatively low. Laser cleaning machines also have a longer service life, further improving their long-term cost-effectiveness.
How to Choose the Right Laser Rust Removal Machine?
Whether the humid environment makes your metal workpiece rust or the old paint peels off the machine, you need a safe and effective cleaning solution.Laser rust removal machine can safely and efficiently remove rust, oil, paint and other contaminants from workpieces. Once you decide to buy a laser rust removal machine, you should study how to choose the right one.
The two primary issues in determining which laser rust removal machine to choose are: first, confirm what type of product you want to clean and what are the main contaminants on such products. Based on these two major issues, there are many small issues that you need to confirm. For example, the size, area, shape of the workpiece to be cleaned, laser power and pulse power, laser safety, cleaning speed and number of times, mobile function, overlap rate and energy density, after-sales service, etc.
(1) Workpiece size and shape: The size and shape of the workpiece determine the size of the laser cleaning machine required.
(2) Laser power and pulse power: There are two typical laser frequencies for laser cleaning machines: continuous and pulsed.
Continuous laser machines can produce a constant flow of energy. The uninterrupted laser frequency can produce a high-quality and effective laser beam. At the same time, this type of laser machine also requires high energy consumption. Pulsed laser machines produce interrupted laser frequencies at regular intervals and are famous for cleaning, marking, and etching. Therefore, when choosing a laser cleaning machine, you need to consider the laser power type based on your needs.
(3) Cleaning speed and number of times: The number of cleaning operations refers to the number of operations required to achieve the required cleaning standard. Different laser cleaning speeds will result in changes in surface roughness. Sometimes continuous cleaning operations are required to achieve the ideal cleaning state.
(4)Laser safety: Safety is the primary factor to consider when purchasing a laser cleaning machine. Laser machines usually require a Class 1 safety enclosure to ensure safety at work. If the laser machine is already equipped with a Class 1 safety shield, then you do not need additional protective equipment. For handheld laser cleaning machines, the safety enclosure level should be ensured. If it is a Class 4 safety shield, the protection does not meet the safety standards, and you need to prepare additional personal protective equipment.
(5)Mobile function: According to the mobile function classification, laser cleaners can be divided into three types, namely handheld laser cleaning machines, fixed laser cleaning machines, and cabinet systems. Handheld laser cleaning machines are smaller in size, weighing about 15-100 kg, and can be placed in a suitcase, which is suitable for repairing smaller metal parts. Fixed laser cleaning machines have a faster cleaning speed than the other two cleaning machines, which can better ensure the production efficiency of the factory. It uses a conveyor belt to transport the parts to be cleaned to the laser gun to automatically clean the metal surface. The cabinet system has a safety enclosure to ensure the safety of work to the greatest extent.
(6)Overlap rate and energy density: Overlap rate and energy density change the cleaning speed, pulse frequency and power. These two parameters will tell us the productivity of the entire machine and can be found in the lab test documents that come with the laser cleaning machine.
(7)Smoke exhaust: During the laser cleaning process, a large amount of pollutants are generated. During this process, the laser cleaning machine will convert the pollutants into dust and smoke. Therefore, cleaning these pollutants in the working area is something that needs to be considered. This is crucial for paint stripping work because harmful substances will be released into the air.
(8)Budget:When buying a laser cleaning machine, the price is the most important factor to consider. The price of the machine usually depends on the size, brand, power, and technology of the machine. There are hundreds of merchants selling laser cleaning machines on the market, and the selling prices are also different. At this time, the price, machine parameters and machine technology must be combined to determine the cost-effectiveness of the machine. The laser cleaning machine currently sold by Blue Elephant can be regarded as a very cost-effective machine in the market. The price is right and the machine performance is also very good.
(9)Brand and after-sales service:Brand and after-sales service are one of the most important factors in purchasing a machine. When purchasing a laser cleaning machine, it is very important to choose a manufacturer with a good reputation and strong technical support. Even if you buy a good cleaning equipment, you will inevitably encounter technical problems when using it for the first time. There will also be some machine equipment failures during daily use, and the value of the machine after-sales service is reflected at this time. Therefore, you need the manufacturer to respond to your questions in a timely manner and provide solutions to your problems. You also need to ask about the postage required for repairs to avoid unnecessary trouble later.
