Laser cutters help small shop owners to grow their business

 Known as “the fast knife” and “the brightest light”, laser can basically cut anything. From metal to non-metal materials, there is always a suitable laser cutter that can provide the most efficient cutting. As the laser cutter market becomes bigger and bigger, the price of the laser cutter is getting lower and lower and many small shop owners can afford to buy one. These small shop owners include gift shop owners, small textile processing workshop owners, etc ... So what kinds of benefits that laser cutters can bring to these small shop owners?

1.Affordability and compact size
Nowadays, laser cutter is not as costly as it used to be, thanks to the continuous development of the laser technique. For small shop owners, since the materials to be cut are often non-metal like wood plastics, paper, etc., an entry-level laser cutter would be sufficient. It has the basic cutting and engraving functions and doesn’t cost much. In addition, entry-level laser cutter often features a compact size and that is another benefit that laser cutter can bring to the small shop owners. As we know, small shop owners have limited space in the shops, so everything needs to be as space efficient as possible.

2.Ability to cut irregular objects
Small shop owners often receive many requests of personalization which comes in irregular shapes. The ability to provide more personalization means bigger opportunity to grow their business. With laser cutter, cutting irregular objects is just a piece of cake and can be done in a very efficient way.

3.No further processing required
Since laser cutting is non-contact, the cut line has no burr on the edge and can be quite straight. That means small shop owners don’t have to do the further processing like polishing that is very common in traditional cutting. That can save them a lot of time and more orders can be processed efficiently.

As mentioned before, an entry-level laser cutter would be sufficient for small shop owners. It is often small and powered by CO2 laser glass tube below 100W. But the CO2 laser glass tube would generate heat while working, it requires a water chiller to take away the heat for normal operation. S&A Teyu CW-3000, CW-5000 and CW-5200 small recirculating chillers are the preferable choices for the small shop owners. They all have small sizes and feature ease of use and installation, superior cooling performance and low maintenance. We also provide 24/7 customer service and 2-year warranty, so you can rest assured using these small recirculating chillers.

The advantages of using laser cutting machine on plastics

Nowadays, the plastics industry has already introduced laser cutting machines to the production line to improve productivity. Laser cutting machine focused the laser beam on the surface of the plastics surface and then the material surface will melt under the high heat of the laser. The laser beam moves along on the material surface and certain shapes of plastics will be finished cutting.

When it comes to plastics, many people will think of the bucket, basin and other daily used items. As society develops, plastic products are not only limited to those items. In automobile, electronics, medical equipment, aerospace and high precision machinery, you can also see the application of plastics. There are many advantages of using laser cutting machine on plastics:

1. As we all know, laser cutting is a kind of non-contact cutting and the plastics cut by laser cutting machine has neat cut edge and without deformation. Generally speaking, after being cut by the laser cutting machine, the plastics won’t require post-processing any more;

2. Using laser cutting machine on plastics can improve the product development speed. That is because after deciding the design in the diagram, users can have the plastics cut very quickly. Therefore, users can get the most updated plastics sample in the shortest production time;

3.Plastics laser cutting machine doesn’t require molding, which means users don’t have to spend money on opening molds, repairing molds and changing molds. That helps save users a lot of expense.

You might wonder what laser source is used in plastics laser cutting machine, right? Well, plastics belong to non-metal materials, so CO2 laser source is the most ideal one. However, CO2 laser source generates substantial amount of heat in the production, so it requires efficient process cooling chiller to take away the extra heat. S&A Teyu CW series process cooling chillers are the perfect match for the CO2 laser cutters. They feature ease of use, easy installation, low maintenance, high performance, high durability and reliability. For bigger models, they even support RS485 communication protocol, which enables communication between the chillers and the laser systems.

CO2 laser glass tube vs CO2 laser metal tube, which is better?

CO2 laser belongs to gas laser and its wavelength is about 10.6um which belongs to infrared spectrum. The common CO2 laser tube includes CO2 laser glass tube and CO2 laser metal tube. You may know that CO2 laser is a very common laser source in laser cutting machine, laser engraving machine and laser marking. But when it comes to choosing the laser source for your laser machine, do you really know which one is better?

Well, let’s take a look at them one by one.

CO2 laser glass tube

It also known as CO2 laser DC tube. As its name suggests, CO2 laser glass tube is made from hard glass and it is normally a 3-layer design. The inner layer is discharge tube, the middle layer is water cooling layer and the outer layer is gas storage layer. The length of the discharge tube is related to the power of the laser tube. Generally speaking, the higher the laser power, the longer the discharge tube will be needed. There are small holes on both sides of the discharge tube and they are connected to the gas storage tube. When it is working, CO2 can circulate in the discharge tube and the gas storage tube. Therefore, the gas can be exchanged in time.

Features of CO2 laser DC tube:

1.Since it uses glass as its shell, it is easy to crack or explode when it receives heat and vibrates. Therefore, there is certain risk in the operation;

2.It is a traditional gas-moving style laser with high energy consumption and big size and requiring high pressure power supply. Under certain circumstances, high pressure power supply will lead to improper contact or poor ignition;

3.CO2 laser DC tube has short lifespan. The life span in theory is around 1000 hours and day by day the laser energy will decrease. Therefore, it is hard to guarantee the consistency of the product processing performance. Besides, it is quite complicated and time consuming to change out the laser tube, so it is easy to cause delay in the production;

4.The peak power and the pulse modulation frequency of the CO2 laser glass tube are pretty low. And those are the key features in material processing. Therefore, it is hard to improve the efficiency, accuracy and the performance;

5.The laser power is not stable, causing big difference between actual laser output value and theoretical value. Therefore, it requires to work under big electrical current every day and precision processing can not be done.

CO2 laser metal tube

It is also known as CO2 laser RF tube. It is made from metal and its tube and electrode are also made from compressed aluminum. The clear aperture (i.e. where plasma and laser light is generated) and the working gas are stored in the same tube. This kind of design is reliable and doesn’t require high manufacturing cost.

Features of CO2 laser RF tube:

1.The CO2 laser RF tube is the revolution in laser design and production. It is small in size but powerful in function. It uses direct current instead of high pressure power supply;

2.The laser tube has a metal and sealed design without maintenance. The CO2 laser can work over 20,000 hours continuously. It is a durable and reliable industrial laser source. It can be installed on the workstation or small processing machine and has more powerful processing ability than CO2 laser glass tube. And it is pretty easy to change out the gas. After changing out the gas, it can be used for another 20,000 hours. Therefore, the total lifespan of the CO2 laser RF tube could reach more than 60,000 hours;

3.The peak power and the pulse modulation frequency of the CO2 laser metal tube is pretty high, which guarantees the efficiency and accuracy of material processing. The light spot of it can be pretty small;

4.The laser power is pretty stable and remains the same under long-term working.

From the above illustration, their differences are quite clear:

1.Size
CO2 laser metal tube is more compact than CO2 laser glass tube;

2.Life span

CO2 laser metal tube has longer life than CO2 laser glass tube. And the former only requires gas changing out while the latter requires the whole tube changing out.

3.Cooling method
CO2 laser RF tube can use air cooling or water cooling while CO2 laser DC tube often uses water cooling.

4.Light spot
The light spot for CO2 laser metal tube is 0.07mm while the one for CO2 laser glass tube is 0.25mm.

5.Price
Under the same power, CO2 laser metal tube is more expensive than CO2 laser glass tube.

But either CO2 laser DC tube or CO2 laser RF tube, it requires efficient cooling to work normally. The most ideal way is to add a CO2 laser cooling system. S&A Teyu CW series CO2 laser cooling systems are very popular among the laser machine users due to superior cooling and offering different stability and refrigeration capacity to choose. Among those, small water chillers CW-5000 and CW-5200 are the most popular ones, for they are compact in size but not having powerful cooling performance at the same time.

Why fiber laser can gain the market share so quickly in the laser market?

As the economics continues to grow and the laser techniques are having more and more breakthrough, laser cutting machines have been widely used in aerospace industry, automobile manufacturing, sheet metal fabrication, etc.. And the advent of fiber laser cutting machine is no doubt the time-changing event in the history of laser cutting. As we all know, laser source is the most important component in a laser cutting machine. And here is a question - why fiber laser can gain the market share so quickly and is known by so many people? Now let’s take a closer look.

1.Fiber laser has a wavelength of around 1070nm, which is 1/10 of the that of CO2 laser. This unique feature of fiber laser makes it easier to be absorbed by metal materials and enables it to perform faster cutting on carbon steel, stainless steel and other highly reflective materials like pure aluminum and brass.

2.Fiber laser has high quality laser beam so that it can realize smaller light spot diameter. Therefore, it can still achieve very fast processing speed even in longer distance and deeper focal depth. Take fiber laser cutting machine with IPG 2KW fiber laser, its cutting speed on 0.5mm carbon steel can reach 40m/min.

3.Fiber laser is the laser source that has the lowest comprehensive cost. Since the electro-optical conversion efficiency of the fiber laser has reached 30%, so it can reduce electricity cost and the cooling cost to a great extent. Besides, comparing with CO2 laser cutting machine, it doesn’t require any maintenance, which saves users a lot of maintenance expense.

4.Fiber laser has a long lifespan. Fiber laser uses carrier-class high power single-core semiconductor module, so its lifespan under normal use can be more than 100,000 hours.

5.Fiber laser has superior stability. It can still work normally under certain impact, vibration, relatively high temperature, dust or other harsh environment, showing high level of tolerance.

With so many outstanding features, no wonder fiber laser has become the most popular laser source in the laser market. Fiber laser will produce lots of heat when it project laser light on the metal surface. As we all know, heat is fatal to the long-term working of the electrical equipment. This also applies to the fiber laser. Therefore, fiber laser requires an effective process cooling chiller. S&A Teyu CWFL series process cooling chillers are very helpful in providing superior cooling for the fiber laser as well as the laser head. Some chiller models even support Modbus-485 communication protocol, so communication with the laser system becomes much easier. There are a wide variety of pumps and power specifications for selection, so users can choose the ideal process cooling chiller as they need.

How laser marking machine helps consumers identify the real face mask?

 Like rice and oil, face mask has become a necessity in our daily life. However, some bad sellers recycle the used face masks and sell them directly to the consumers without even sanitizing them in order to get the huge profit. Fake face masks are not able to protect us from the virus. What’s more, they are harmful to human body. To identify the real face masks, the most direct ways are to check the laser marked anti-counterfeit labels on the packages or on the face masks themselves.

The real face mask has a laser marked label and that label can indicate different color seeing from different angles. However, the fake one doesn’t have the color change and it is printed by inkjet printing.

In fact, laser marking technique can not only be used to identify the real face mask, it can also be used to identify the authenticity in food, medicine, tobacco, electronics and cosmetics. So why it is so powerful in anti-counterfeiting in different industries?

Well, first, let’s take a look at the working principle of laser marking machine. Laser marking machine uses high energy and high density laser beam on the material surface. The focused light beam will make the material surface vaporize or change its color and its route can be easily controlled. And that’s how the eternal markings are made. Laser marking machines can print out different words, symbols and patterns which can be millimeter or micrometer level.

Before laser marking machines are used widely, the markings on the packages are often printed by ink printing. Markings by ink printing are easy to be removed or altered and disappear as time goes by. What’s more, ink is a consumable, which increases the operation cost and causes pollution to the environment.

Take the food package as an example. Since the markings printed by ink printing are easy to be removed and altered, some bad sellers altered the production date or the brand names of the food and sell them to the consumers. And that is intolerable.

The advent of laser marking machine helps solve the problem of ink printing. Using laser marking machine on the food package is more efficient, more environmental friendly, more clear and more lasting. Besides, the laser mark labels can be connected to the database in the computer so that each of the procedure can be tracked efficiently.

As we all know, laser sources have a wide variety and different laser sources have different applicable materials. For example, fiber lasers are more suitable on different kinds of metal materials; CO2 lasers are more suitable on non-metal materials; UV lasers can work on both metal and non-metal materials but in higher precision and more demanding applications.

In fact, CO2 lasers and fiber lasers have long been found to perform laser marking. These two types of laser sources produce light in infrared wavelength. The marking processing is in fact heating up he materials so that the material surfaces will carbonize, bleach or ablate to indicate different color comparison. However, this kind of heating up will damage the surface of the package, especially the plastic package in food industry, CO2 laser marking machine and fiber laser marking machine are not widely used in food package.

In this circumstance, the advantage of UV laser is more obvious. Most of the materials can better absorb ultraviolet light than infrared light and the photon energy of UV laser is much higher. When UV laser is working on the high-molecular polymer, it can break the chemical bond of the material and then the broken material surface will vaporize to realize the ablation. In this process, the heat-affecting zone is pretty small and very few energy turns into heat energy. Therefore, it is less harmful to the material than CO2 laser and fiber laser. And that’s why UV laser marking machine is more popular in food and medical industry.

As mentioned earlier, UV laser is more suitable for higher precision and more demanding applications. In fact, it is also quite sensitive to to the thermal change. And in order to keep the UV laser at a stable temperature range, it must be equipped with a laser water cooler. S&A Teyu CWUL series and CWUP series laser water coolers are the ideal options. They offer ultra-precise temperature control of ±0.2℃ ~±0.1℃, showing great ability of controlling temperature. Besides, they all have small size and light weight, so you can carry them wherever you want.
