Laser Marking Machine
Laser marking machine is the practice of using lasers to engrave an object. Laser marking, on the other hand, is a broader category of methods to leave marks on an object, which in some cases, also includes color change due to chemical/molecular alteration, charring, foaming, melting, ablation, and more.
Benefits of Laser Marking Machine
Better Quality
One of the major benefits of using laser engraving is that it allows you to brand your products with high-quality markings. Spending on a laser marking machine is a big decision, and when you make an investment like that, you want to see visible results. The beam used in laser marking machines is computer-driven, which means every mark it is printing will be precise. I can also allow you to print complex designs and engraving that would not be possible with conventional methods. You can also print small text on your products or machines, and it would still be easily readable.
Competitive Edge
Another benefit of using laser engraving is that it can help you add uniqueness to your brand. In today's market, the competition is quite tough, and if you want to get ahead of the competition, you will have to gain an edge over your competitors. Laser machines allow you to get creative with your engravings, and you can make your branding look attractive, which can add more quality to your products. It also makes the products traceable, and you can track the inventory more efficiently.
Super-Fast Engraving
The laser engraving method is quite fast and can help you save a lot of time. With conventional engraving methods, you have to use a specific set of tools and have to be very careful as well, and that can be time-consuming. Laser engraving, on the other hand, simply needs command, and it will get the job done without any complications or wasting any time. This can speed up the company's processes and can save them a lot of money as well. The faster you will get things made, the more profits your business will make.
Accuracy
If you want to do engravings on expensive products or machines, then you will have to tread carefully. Just one tiny mistake, and you will damage the whole product, which is something no one wants. With laser printing, you don't have to worry about any of it. The engravings will be precise, and there will be no danger of damaging the product.

Factors To Be Included In Evaluating The Correct Laser Marking System
Moving or stationary marking surfaces
If you need a machine to be included into a processing line for continuous processing of parts, models that can accord part marking of moving parts, at a pre-determined speed are a great choice as they provide high in-process efficiencies.
Line speed
Due to the varying properties of laser wavelengths and power, different systems will give different results depending on the speed with which part production is happening. High speed production lines will need high wattage markers in order to effectively mark all in-process parts.
After Sale Services Provided
Sometimes, machine set up and operation can be tricky. Though most laser marking machines are relatively low maintenance with long lives, working with a supplier who has local expertise or who can provide instant assistance is a good consideration when choosing which equipment to buy.
Environmental conditions
Some machines are sensitive to work environments that have a high propensity for dust, shock and vibrations, while others are robust and can withstand these environments.
Expected Workload
Some laser machines are low speed, and may not work well with high workloads. For example, when marking metals, it could be more cost effective in the long run to work with fiber lasers than with CO2 lasers.
Material To Be Marked
As we shall see later, laser markers can work on a wide variety of surfaces. The marker you use will depend heavily on the marked materials you want to work on. For example, fiber lasers are very good with metals, while CO2 lasers are great with non-metals.
Types of Laser Marking Machine
Fiber laser marking technology has risen in recent times to be one of the most sought after direct part marking technologies the world over.
With power levels ranging from 20-50 watts, Fiber laser marking machines are some of the most powerful laser marking machines in the market.
These machines are ideal for depth etching or engraving, with great results on harder metals or when one needs high powered systems with a smaller spot size to achieve high resolution.
High beam quality and small spot sizes with larger lenses allows fiber laser to be used for small-component batch marking applications or the cutting of very thin metals.
Green Laser Marking machines are designed to mark highly reflective materials. They also work on or highly sensitive substrates like silicon wafers, exhibiting very good work ease and high precision. They operate in the green Near-IR visible light spectrum (at 532 nm) and power ranges of 5-10 watts.
They are perfect for soft plastics, PCB Boards, Integrated Circuit Chips and for scribing or marking of Solar Cells of various material compositions.
The inherent advantages of the 532 nm wavelength include greater absorption across a many types of materials, and mitigated thermal energy allowing it to mark substrates that other higher wavelength simply cannot. Green Laser markers also give very tight spot sizes of up to 10 µm.
Ultraviolet (UV) represents a band of the electromagnetic spectrum with wavelength from 10 nm to 400 nm. They are shorter than those of visible light but longer than X-rays.
Long wavelength UV is not considered an ionizing radiation, because its photons do not have the energy to ionize atoms. However, it can cause chemical reactions that make substances glow or fluoresce.
As a result, the chemical and biological effects of UV are much wider than simple heating, and many practical applications of UV radiation are possible due to its interactions with organic molecules.
Gas lasers, solid state lasers and diodes can be used to make machines that emit ultraviolet rays, and lasers are available which cover the entire UV range.
Since the excimer laser was discovered, it has been possible to avail intense ultraviolet light. Researchers explored and uncovered the unique properties of this new light source. As various phenomena involving UV energy and material interactions were discovered and optimized, practical applications emerged.
CO2 laser marking machines are usually sealed-tube laser marking systems with galvo-steered beams designed for marking non-metal surfaces like wood, glass, quartz, and ceramics. They can also mark fabrics and other organic materials, operating at wavelengths of 10,600nm.
These machines are used to produce barcodes, serial numbers, and logos on metals and other surfaces.
When laser marking bare metal using a CO2 laser, a special marking agent (spray or paste) is used to treat the metal prior to engraving. Once the laser beam is applied, the heat from the laser bonds the marking agent to the metal, resulting in a high contrast permanent mark.
The machines are fast and affordable. They are among the oldest type of engravers and markers, and can also mark organic materials such as wood, ceramics such as tiles, stones and more.
CO2 laser systems can be operated from a wide range of applications like Windows and Linus, and are very easy to use.
Laser Marking by Annealing
In this process, a laser beam locally heats a metal surface to produce a mark. This localised heating causes structural changes in the metal and results in a colour change. The marking is usually black but it may also be red, green or yellow, depending on the temperature of the heated layers.
The laser rays only penetrate 20 to 30 µm into the metal surface. This results in an even surface of the workpiece. This type of annealing is usually carried out on ferrous metals and titanium.
Annealing marking produces permanent abrasion-proof results. A variety of industries use it. Examples include medical, dental, automotive, manufacturing, etc. An example of annealing marking is a nameplate for identifying and listing the machine's specifications.
Laser Engraving
In engraving, the laser beam removes some material from the surface. This produces a mark on the surface in the form of depressions. A large number of materials suit this process. Examples include metals, plastics, stone, and ceramics.
During laser engraving, the material absorbs heat from the laser, melts and evaporates. The material also reacts with air resulting in a colour change which makes the mark more distinctive. As there are no consumables involved, this technique has low operational costs compared to other methods that use drill bits or special inks for engraving.
Laser Marking For Leather
When it comes to marking organic materials and synthetic polymers, carbonising is the way to go. In carbonising, heat from the laser breaks plastic bonds and releases hydrogen and oxygen. Wherever this reaction takes place, the area darkens.
Since the mark formed is grey to blue-grey, carbonising is not always suitable for dark-coloured objects. This will lead to low contrast between the marked portion and the rest of the workpiece. Carbonising is used to mark wood, paper, leather, packaging material, etc.
How 8 Industries Use Laser Marking Systems
Pharmaceuticals
The pharmaceutical industry benefits greatly from the use of laser marking machines, specifically regarding capsule marking and pill imprint coding. Due to government regulations, all medications sold to the general public must feature an identifying marking that provides information on drug type and dosage (some pill and capsule markings also denote trademarks and company logos or imagery). There are several different methods for creating these imprint codes, including debossing, embossing, printing, and engraving.
However, laser marking is perhaps the most effective and efficient method for labeling pills and capsules. This technique is non-destructive, making it highly suitable for marking sensitive medications. Plus, the process is much quicker than pressing drugs or other traditional marking methods. Lastly, UV laser marking is non-contact and extremely sanitary, eliminating instances of cross-contamination during production.
Automotive
Automotive manufacturing is a complex process that's highly regulated and involves an exorbitant amount of components, equipment, and parts. UV laser marking machines are used in manufacturing to mark and identify various parts traveling along the assembly line. More importantly, laser marking is an invaluable method for safely labeling vehicle-related wires.
Why is marking automotive wires so essential to the industry? Mainly, it helps with cable management and makes maintenance work far easier for electricians. Additionally, it ensures better-assembled vehicles that are safer for the general public. Ultimately, UV laser marking machines make the manufacturing process simpler, faster, and more effective.
Aerospace
Just as with the automotive industry, laser marking machines help improve the success and efficiency of aerospace manufacturing. Furthermore, UV laser marking methods are often needed in this industry, as many aircraft components are made from unique and exotic materials that are resistant to other marking techniques.
The non-contact, non-destructive nature of UV laser marking ensures that airplane parts remain structurally sound and functional. Plus, this specific industry is heavily regulated (for a good reason!), so having a dependable, fast, and accurate method for labeling metals, plastics, and wires is paramount. Military defense manufacturers also use the same equipment as the aerospace businesses for many of the same reasons listed above.
Jewelry Making
While UV laser marking is often implemented in specific, highly-industrial environments, it is beneficial in jewelry marking applications. For instance, certain metals react poorly to engraving and other marking techniques. Plus, engraving is a slow and sometimes imperfect process that's impractical for large-scale jewelry-making operations. Since UV laser marking merely changes the properties of a given surface, it's a very safe and efficient tool for lapidaries. Additionally, this method is suitable for accurately marking tiny objects, such as pet name tags, necklace charms, ring bands, and more.
Medical device manufacturing
UV laser marking is highly useful for many different applications, but perhaps none more than medical device manufacturing. Similar to other industries on this list, medical device manufacturers are under strict government regulations to ensure the safety and well-being of patients.
UV laser marking is non-contact and highly sterile, making it ideal for creating labels on implants, catheters, and other devices. And since little heat is required, medical devices won't accidentally suffer damage during the marking process. As a bonus, the indelible marking produced by laser marking machines is durable in any environment, including inside the human body, as the imagery will never fade away.
Electronics
Plenty of engraving methods used within the electronics industry are effective, but none are as capable of labeling tiny components as UV laser marking machines. When microchips, circuit boards, resistors, and other smart electronic parts require markings, laser machines are used to produce accurate and clear results. You can even adjust the wavelength of your laser machine to mark microscopic objects successfully! And, as stated before, there's no risk of the UV laser beam damaging delicate electronic materials.
Wire And Cable
Wire and cable manufacturing is a very specific industry that, among other things, is responsible for processing many products at once. Properly labeling such a massive number of wires and cables during production requires comprehensive machinery. That's where UV laser marking comes into play; these machines are built to process many cables and wires at a quick pace without sacrificing image quality. And, of course, UV laser marking is non-destructive, especially when interacting with sensitive insulation jackets and electrical components.
Food And Beverage
UV laser marking machines are extremely useful during the food and beverage manufacturing process! Food and beverage processing plants often install laser marking machines on their assembly line. Their function is to create lot numbers, expiration codes, and other important markings on the product packaging.
These devices can label a wide array of materials, including plastic, ceramics, glass, and more. Plus, they work quickly and effectively, helping expedite the processing and manufacturing processes. UV laser marking machines are automated to further increase productivity.
As you can see, these various industries use laser marking systems in very different ways. Some utilize this technology for its efficiency and accuracy. Other businesses benefit from the non-destructive and sanitary manner of laser marking techniques. Overall, every industry that has regulated or specific manufacturing processes can benefit from installing laser marking systems in their facilities.
For some applications, such as jewelry making, a small device is all that is needed; however, large-scale operations in the medical device or pharmaceutical manufacturing sector may require more equipment.
