Every company, business, industry, or manufacturer would have at one point in time needed a design etched on a material. Therefore, it is safe to say that almost all companies have heard of the word marking machine/markers. Marking machines and their corresponding processes go a long way in designing. For example, manual engraving has been a craftsman tool for centuries and is still relevant.
Now, there are many markers used nowadays for marking designs on different types of objects. Each marker has its features and application, making some more suitable for a particular material and project than another. There is a lot of information to take in. However, most people are not familiar with the different kinds of markers used nowadays. To make it easy for you to choose the right marker, this article will discuss every marker used in marking products. This will be in terms of the process, mechanism, and applications.
What are Marking Machines?
A marking machine or a marker is a device applicable in the creation of marks (any form of design, e.g., logo, name, serial number, bar code) on materials. Such designs are important in product identification, branding, and tracing of products. Consequently, many industries at least have one marker in their inventory.
Dot Peen Marking System and Machines
Dot peen marking machines are common in industries that deal with heavy-duty materials and products. It is a machine that works based on the dot peening marking system and is employed in a situation where a laser marking machine is not suitable for marking.
A dot peen marking machine is made up of a stylus that strikes the material to be marked electromechanically or pneumatically. This forms successive and precise dots that create the required design. You can watch how a dot peen marker works here.
Advantages of Using a Dot Peen Marking Machine

Laser Marking Machines
Currently, laser markers are the most popular marking machines used in industrial settings due to the ease of marking, efficiency, quality, wide material compatibility, etc.
A laser marker works by focusing laser beams on the surface of a material. The laser beam depending on the type of laser marking process and the power used can lead to different forms of alteration in the material.
How Does a Laser Marking Machine Works?
There are many types of laser marking systems, and each one uses a laser marker via a different mechanism. The three popular lasers marking procedures are:
– Laser Engraving
Laser engraving is the most popular laser marking process based on efficiency and permanent markings. It involves using a laser engraving machine to remove part of a material. Laser engravers have optimal frequency, speed, short pulse, and high peak power and are suitable for non-reflective materials and products not used in wet and saline environmental conditions
– Laser Etching
Laser etching is a similar process to engraving. It involves the use of a fiber laser marking machine, which produces a laser beam that raises the surface of the material. Hence the marking. Laser etching produces a white, gray, and black color.
– Laser Annealing
Laser annealing involves using a laser marking machine to color the surface of the material. This occurs as a result of the increase in temperature of the material causing oxidation of the point of contact. It is the only non-eroding laser marking method out of the four laser marking systems highlighted and is commonly used for marking surgical instruments.
– Laser Foaming
Laser foaming involves using a laser marking machine to heat the material so that it begins to foam. This leads to the surface of the material bulging forwards, producing textured marks. Laser foaming is a suitable method when a clear marking is required as it gives a localized height change.
Types of Laser Marking Machines
There are four types of laser marking machines that you can consider for marking a product. Each one has its features and material compatibility, making knowing them very important before selecting one.
· Fiber Laser Marking Machine
Fiber laser markers have a wide compatible material, mainly metals, plastics, and glasses. They are efficient, reliable, cost-effective, and deliver quality and permanent markings. Fiber laser marking machines are compatible with the types of laser marking systems discussed above. However, unlike other machines, it is the only machine suitable for laser etching because of the wavelength at which it operates.
· UV Laser Marking Machine
The UV laser markers are suitable for marking plastics, metals, and glasses. The machine uses UV light which marks by breaking the bond between atoms holding the material surface together.
UV laser marking machines do not cause peripheral heating, unlike fiber laser markers and CO2 laser markers. Therefore, it does not pose any risk to the material integrity after use. Nevertheless, UV laser marking machines are effective and efficient. Watch the video below on what the right and UV laser marker can do for you.
· Green Laser Marking Machine
Green laser markers are the ideal machine for marking products that are heat sensitive. This is because they operate at a wavelength of 532nm, i.e., it is a low-powered machine with a lesser tendency of burning materials such as soft plastics.
· CO2 Laser Marking Machine
CO2 laser markers are a very powerful type of laser marker that uses a CO2 gas mixture. They are the suitable laser marker for marking any non-metallic material such as acrylic, PVC, rubber, leather, etc. Consequently, they are a huge part of the printing and packaging industry, advertising industry, model industry, etc. Watch the video below on what the right and UV laser marker can do for you.
Applications of Laser Marking Machines
Laser markers have wide use in different industries in marking different designs, based on their compatibility with different materials. It is suitable for marking both no-metal and metal materials, including stainless steel, aluminum, silver, gold, etc.
Applications of Laser Marking Machines
Chemical Etching Machines
A chemical etching machine is an aggregation of different components that works to create a permanently etched image on different materials. The machine harnesses the corrosive action of a chemical (mostly ferric chloride) against the material to be marked at a high temperature and pressure.
Chemical etching results in better colors and should be your targeted machines if your design requires more color. This is unlike dot peen markers and laser markers that only produce white, black, and gray.
How a Chemical Etching Machine Work
An etching machine uses a chemical spray to dissolve parts of a material to give the required design. Etching a particular part is possible by covering other parts in non-degradable components. This is further explained in the steps below:
The first step is to clean the metal surface thoroughly. This is because the presence of debris can lead to irregularities during etching.
Laminate the metal properly before using a UV-sensitive photoresist film. There are other options you could use, with popular ones being dry, wet-dip, and roller lamination.
Place the photo tool containing the desired design on the laminated metal and expose it to UV light. The UV light passes through the laminated film, hardening it and giving it acid-resistant properties.
Develop a resist film on the non-exposed area to reveal the desired image. You should also heat to improve acid resistance.
Place the developed metal in an etching machine and spray it using chemical spray (the common spray used is ferric chloride). The chemical spray etches the exposed metal part
Strip the resist manually or with a stripping machine. You can then begin any post etching process to further make the metal part aesthetically good.
Advantages of Using a Chemical Etching Machine
- Inexpensive, flexible tooling for quick prototyping and design changes
- Metal properties do not change
- Low-cost process for products with complex designs
- Quick turnaround
Inkjet Marking Machine
An inkjet marking machine (thermal inkjet printer) has three main parts: host, power supply, and print head. The machine marks the product by using ink traveling at high speed. This is heated to above 300 ℃ to form numerous tiny bubbles which travel at high speed in the process, expanding to larger bubbles. This forces the ink droplet to be ejected from the print head to form the desired text, numbers, barcodes.
After expansion, the bubble fades back into the resistor leading to the ink shrinking back from the nozzle. This will generate a suction that draws new ink to the ejection area for the next cycle. This mechanism of action makes printers are widely popular in the market and used in almost all industries.
