Why laser cleaning is more profitable than sandblasting and other. Laser equipment for surface cleaning.

Fantastic laser Cleaning and Where It Dwells

It lives, for example, in the laser cleaning system or in the portable Backpack.

Actually, you don’t need anything else for cleaning – no chemicals, no consumables, just electricity to plug in or charge the batteries in the mobile version. Only the light works here.

The magical action itself takes place according to the laws of physics, no magic:

• The laser source emits a high intensity pulsed light beam;
• The light pulses are absorbed by external contamination, where they create pockets of ionized gas;
• Since this takes place in a very limited space, a microburst appears in the impact focus, the shock wave of which tears off even the ingrained layer of contaminant;
• The particles detached by the laser are removed by the integrated suction system.

It must be understood that the cleaning itself occurs precisely on the surface of the dirt, almost without affecting the substrate – the light only affects the dirt itself, the metal reflects it to a large extent.

The pulses are so short that it has no time to heat up, and therefore no deformations can occur.

And, of course, the beam does not care how complex the shape of the treated area is – unlike a brush or sandblaster, it will penetrate everywhere.

This means that a dirty part of any shape can be painlessly reanimated rather than being scrapped.

Is it possible to save money? Which option Laser to choose?

Although they say there’s no such thing as cheap, there is an exception to this rule: laser cleaning is certainly more expensive than sandblasting, but not by an order of magnitude.

And considering that it doesn’t need consumables or special protective equipment, and has a service life of up to 100,000 hours before the laser head is replaced, the cost of using laser cleaning beats all the others by a landslide.

However, there is a cheat-code for the purchase of devices: there is no difference in quality between European, Japanese and Chinese units on the market today.

But there is a multiple difference in price.

How does laser surface cleaning work?

Ultra-short pulses (on the order of nano-microseconds) with several million watts of power are directed at the surface to be cleaned.

The energy to be acted upon causes the contamination to explode, some of which evaporates and the remainder disperses as dust and can be removed by a filtration system.

This process is repeated until the desired removal depth is reached.

The laser radiation is absorbed by organic materials such as paint, insulation or rubber.

Why laser light?

The development of laser cleaning has been influenced by the need for non-abrasive and safe cleaning that can replace the use of chemical solvents and mechanical abrasive systems.

One of the key problems characterizing most traditional cleaning methods is the damage to the substrate and the negative impact on the environment.

Abrasive cleaning damages delicate surfaces and is accompanied by large amounts of contamination.

The use of chemical solvents, on the other hand, is accompanied by liquid waste and potentially hazardous fumes.

Potential application of the equipment Laser Cleaning

• Rust removal.
• Paint and varnish removal.
• Restoration work – cleaning stone surfaces, monuments, sculptures and buildings.
• Cleaning of rubber and plastic molds and rollers.
• Confectionery and food molds – Cleaning molds in food production.
• Tool cleaning.
• Pretreatment of surfaces before welding, gluing or painting.
• Removal of oil residue on milled parts.

What are the advantages of using laser equipment?

Lasers do not use consumables, so there are virtually no long-term operating costs, except for electricity consumption.

Many „local laser skeptic professionals“, at this point, will loudly shout that the „lamp“ will burn out immediately, and here we should point out that this would not be entirely true.

First of all, any „local expert“ who claims that lasers are worse than conventional technology which consumes any kind of raw material, is first and foremost an interest in advertising their product and then the monthly profits from selling consumables to the customer.

Secondly, the benefits of using the laser in the production environment have been proven over the years by the fact that we can see more and more laser-labeled products on our store shelves.

In addition, we would like to point out that most products from the „Western countries“, will be laser marked and products from

Eastern Europe and Russia will be marked with inkjet solutions.

In the Western countries, where the efficiency and optimization in the production processes production processes are much more advanced than in the Baltic countries, lasers are widely used both for product marking and surface cleaning.

Third, the profitability of the laser is very easy to prove with simple mathematical calculations.

For example – in the marking field, the expected lifetime of a laser diode by 2022 is up to 500,000 operating hours.

But in 2021 this number was up to 250,000 operating hours, which only proves how fast laser technology is developing.

The average lifetime of a laser light source used in laser cleaning, right now in 2023 is about 100,000 operating hours.

Any entrepreneur who doubts the economic benefits of laser equipment can make a calculation on their own to see how much they will save by using laser equipment in their industry.

Non-contact cleaning , no abrasive risk – no risk of damage.

The laser cleaning technology, in contrast to competing technologies does not touch the product – it is cleaned by means of a laser beam. Consequently, damage to the surface is virtually impossible.

Laser cleaning is suitable for surfaces that cannot be cleaned with abrasive technologies.

• Laser-cleaned molds last much longer than those in which an abrasive method was used.
• Wood and other organic materials can also be cleaned with the laser.

Automation Laser Cleaning.

Laser cleaning equipment can be installed on production lines to clean parts, products or molds without having to remove parts from the production line.

If the production process can be integrated into an existing process, for example, to clean parts or molds, switching to laser cleaning technology can mean cost and time savings.

• Laser cleaning equipment can be integrated – installed on an existing production line.
• If currently the molds are removed from the production line and transferred to a washing machine, it is possible to get rid of this process by laser cleaning without having to remove the molds from the production line.

Ecology and getting rid of hazardous chemicals.

Often consumers do not think about the fact that those foods that have been labeled as organic have gone through molds during the production process that have been washed – scrubbed with strong chemicals.

Thus, it is as if we are paying more for an organic product while it was produced in molds that had previously been washed with strong industrial chemicals.

Using laser cleaning equipment, food molds can be cleaned without any chemicals, thus ensuring a truly environmentally friendly product and allowing the manufacturer to eliminate the cost of buying chemicals and to eliminate the additional production cycle.

• No chemicals.
• Without any residue or waste.
• Mold cleaning can be installed on an existing conveyor and integrated into the production cycle.

High accuracy laser Cleaning.

The laser beam is almost the same as the light beam, so the so-called resolution („dpi“) is the highest possible compared to any other technology.

The laser beam is finer than grains of sand, plastic or metal, which can be used in abrasive surface cleaning equipment Therefore, the result of laser surface cleaning will be much better than with other cleaning technologies.

Speed Laser cleaning of surfaces.

Time is money, at this point, many say that our entrepreneur-producers need to increase efficiency to be able to compete with „Western manufacturers.

Yes, this is the case. As long as our entrepreneurs are investing in yesterday’s technology, it will be harder for them to achieve better production results than Western manufacturers who use modern technology Laser cleansing technology is a new technology that is developing rapidly, and like anything new, it seems complicated for some people.

The other dedicates the first half of the day to changing clothes and preparing equipment for sandblasting… A third entrepreneur will do the same process without waiting, without preparation, by simply „transitioning“ the laser over the product.

While the first two will clean up the work environment after cleaning one part, getting rid of chemicals and sandblasting residue, the third will continue working with the laser while all process residue is automatically fed into the ventilation system.

Safety Laser cleaning.

No chemicals – almost impossible to poison someone or get fined for improper disposal of chemicals.

Non-contact technology – Very difficult to „punch or corrode“ a hole in a thin, soft or sensitive material.

Can work with materials that could not be handled with abrasive cleaning methods.

Flexibility and a wide range of uses.

The laser cleaning equipment is available in a stationary kit – for assembly on production lines as well as, for a portable solution. Laser cleaning equipment can be built into a van, and all that is needed to prepare for operation is a stable and appropriate power source.

Micro – application Laser cleaning.

In the electronics industry, there is a need for wire stripping in order to weld or solder connectors, terminals, or splices.

For example, the insulation on thin wires, such as flat wires, can be effectively removed without damaging the copper conductor.

Unlike mechanical stripping, the laser is able to remove insulation as thick as 1 µm or the silver coating of the conductor, without affecting the corrosion protection layer.

Automotive brake systems or cooling systems have polyamide coatings to protect them from wear and corrosion.

Macro – application Laser cleaning.

In the production of rubber products and in tire production, there is a need to clean the molds after the mold has made several hundred products.

Molds in which cooling takes place must be dismantled and cleaned using mechanical systems or chemical solvents.

The process is time-consuming and can also damage expensive tooling.

Cleaning a mold for a typical passenger car tire takes about eight machine hours, and about the same amount of time is spent on related work. Using a laser allows the molds to be cleaned without disassembly, directly on the working machine, and without possible damage.

A mobile laser unit can clean a tire mold in 45-60 minutes, the area of which is a little less than 1 m2.

Laser. How to use it correctly? Using a laser to remove rust is not difficult. The treatment technology involves going through the following steps:

• the installation is put into operation;
• Scan the surface, determining the depth of rust;
• Direct the beam of light to the surface to be cleaned;
• Hold the laser beam source in the desired position until the desired result is achieved;
• control of the ablation depth allows selective removal of corrosion of different thicknesses.

Is it possible to make one Laser cleaning with my own hands?

It is not possible to make a laser to remove rust from metal with your own hands.

Only factories that specialize in this area can assemble a unit that will scan the thickness of the corrosion and then safely remove it.

You can try to assemble the device yourself if you have all the necessary components.

You will have to order and buy them in a store or buy them from abroad.

This is quite a time-consuming process, so it is much easier to buy a ready-made unit.

Where to buy Laser Machine, what is the price?

You can buy a laser for rust removal on the Internet.

Depending on the country of manufacture, you order either directly from the manufacturer or through specialized services.

The price of the equipment varies within a wide range.

It depends on the power of the device, the features of its functioning, the scope of application and accessories.

You can try to save money and buy a unit that was previously in use, but there are no guarantees of its proper operation.

The price of used lasers starts from 3000 dollars.

If it’s broken Laser Machine, how do you fix it?

Laser units should be repaired by professionals. You should not try to repair it yourself, even if you have knowledge of electronics.

It is not difficult to find a specialist.

It is sufficient to enter the appropriate request into the search box of any browser.

If the workshop does not have the parts that need to be replaced, they must be ordered.

In this case, you will have to wait for delivery, as well as pay additional shipping costs.

Conclusion laser cleaning method

When deciding on the choice, one has to clearly understand the purpose for which the laser will be used.

The larger the amount of work to be done, the more powerful the instrument must be.

Today it is laser equipment that allows you to quickly and gently clean metal from rust without fear of damaging parts.

Advantages of the laser rust cleaning method
