Laser Marking Source | Laser Types & Selection Considerations

, ,

Laser part marking requires an understanding of both the engraver that will best fit your application requirements and the laser source that will provide the best mark. There are a variety of laser sources, and we will highlight three types, as well as two subtypes, of the best laser-marking technology and outline the best choice for the material you are using and the depth of the mark you require to meet regulatory requirements.

5 Laser Sources Based on Wavelength

Laser part marking is common in a number of industries because it is effective for long-term part identification and meets the rigorous standards set forth for aerospace, mechanical, and other high-demand industries.

However, each industry has specific needs when it comes to the product, and the potential damage to the product if the wrong laser is used. The equipment you need is part of the process, but from there the laser that is best is the next point to consider.

With that in mind, we can take a look at five of the commonly used lasers and the best use case for each:

  1. CO2 laser
  2. Fiber laser
  3. YAG laser
  4. Green laser
  5. UV laser 

1. CO2 Laser

CO2 laser marking is a popular laser engraving and marking solution because of its ability to mark non-metallic materials. It’s efficient in marking a variety of non-metals, too, including:  

  • wood
  • plastic
  • glass
  • textiles
  • cardboard

The CO2 laser produces an infrared laser beam and uses CO2 gas as the active medium. The laser is emitted at 10.6 micrometers and features high beam quality, allowing it to focus laser power into a small spot and produce high-quality laser marks. This laser has the longest wavelength, which is located on the invisible infrared spectrum. 

This laser is efficient for cutting some materials and for personalizing products. However, this type of laser also requires more maintenance and uses more energy.

 

2. Fiber Laser

Another laser source is fiber laser marking, which also offers the ability to mark non-metallic surfaces with a high degree of accuracy. This laser source utilizes a shorter wavelength than a CO2 laser and uses a fiber optic laser device to emit laser beams at a wavelength of 1.064 micrometers. The wavelength produced is located in the infrared spectrum.

It quickly and accurately produces laser marks on materials such as:

      • plastics
      • metals
      • rubber
      • glass

 This laser source also offers the ability to be tuned for specific applications with easily adjustable settings. 

A fiber laser can also be used for embossing or to add discoloration where desired. The discoloration process with a fiber laser provides a variety of colors and better control simultaneously. 

The fiber laser is the most commonly used in the laser marking industry, particularly common in aerospace, metallurgy, automotive, and mechanical applications. It’s useful for all types of metals and has a long lifespan when compared to other lasers.

3. YAG Laser 

The YAG laser operates on a wavelength similar to the fiber laser (1.064 micrometers). However, this type of laser has a different structure than a fiber laser and the beam passes through different crystals in order to create the beam. 

The YAG laser is ideal for marking metals and plastics in its more widely recognized configuration. However, it can be adjusted to mark more sensitive materials as well.

4. Green Laser

The green laser, the first subtype of the YAG laser, is the only laser with a wavelength in the visible spectrum. This allows manufacturers to mark many sensitive materials, such as: 

  • polymers
  • plastics
  • rubber 

The green laser is ideal for these sensitive materials because its wavelength is located near the UV spectrum generates less heat.

5. UV Laser

The UV laser is another subtype of the YAG laser. Thanks to implanted crystals, it became possible to adjust the wavelength for this laser and utilize others, providing access to the only laser in the invisible ultraviolet spectrum (0.355 micrometers).

The UV laser has the shortest wavelength used in the laser marking field and as such is relied upon for markings on fairly sensitive materials.

This laser also makes it possible to carry out “cold markings” — which means manufacturers can avoid the degradation of parts due to the heat. This laser is  used for marking solar panels, electrical components, and other parts that require a refined approach.

 

6 Ways to Choose a Laser Marking Source

Planning production of your next line means a lot of considerations. These include the material you will use and the speed you can expect products to be completed. Meanwhile, several of those factors also influence the choice of laser: 

  1. Material to be marked 
  2. Mean time between failures (MTBF)
  3. Depth of mark needed
  4. Laser maintenance needs
  5. Speed of marking process
  6. Ease of settings adjustment

 

1. Material to be Marked

With the variety of materials used in production, it makes sense to prioritize the materials when considering a laser source. For more heat-sensitive materials, it’s important to find the right laser and access one that is easily adjustable.

 

2. Mean Time Between Failures (MTBF): 

The Mean Time Between Failures (MTBF) is a guideline of how reliable your laser will be based on its hours of operation. Each laser has a different expectation — and keep in mind these are mean times, not a guaranteed lifespan. Some lasers have a longer MTBF but can fail in a shorter period of time than expected 

While the fiber laser has an MTBF of 100,000 hours, CO2 lasers have a significantly shorter MTBF of 30,000 hours. This is a crucial factor to keep in mind while choosing the best option for your production cadence.

 

3. Depth of Mark Needed

Some lasers are singled out for the ability to make deeper marks than others. For certain regulations and standards, the laser with a deeper marking capability would be the preferred choice. 

Meanwhile, other materials require a lighter mark that doesn’t cause damage. Therefore, the depth of the mark is a key factor in laser source choice.

 

4. Laser Maintenance Needs

Some lasers require more maintenance than others. This means a commitment of more of the budget and possible interference with production timelines if maintenance is required frequently.

 

5. Speed of Marking Process

Your production timeline is important both for your revenue and to help your clients meet their own projected deadlines. As such, the marking process needs to be completed in a timely manner. 

Note: Depending on the material to be marked, the right laser source makes a difference in meeting that timeline and getting behind due to lengthy marking processes. If laser marking isn’t the answer at all, there’s always dot peen marking.

 

6. Ease of Settings Adjustment

In some industries, the laser will need to be adjusted for separate part lines or stages in the production process. In these cases, it is more cost-effective to find a laser that can be adjusted easily. This better facilitates effective marking on the desired timeline. 

 

Which Laser Marking Source is Right for Your Production Needs?

With three laser marking types and two subtypes, it should be a reasonable process to narrow down the best laser for an application based on the factors involved. Your production line requires a certain type of mark and you have an expectation of how long that mark will last.

The right laser marking source means faster delivery of products that carry distinct markings to fit your clients’ needs.

Choose for Your Application: The Right Marking System in Industrial Facilities

, , ,

Part marking systems are crucial across various industries for tracking, identification, quality control, and regulatory compliance. Two popular methods for part marking are dot peen marking and laser marking. Each has its advantages, disadvantages, and typical applications based on factors such as material compatibility, precision, cost, and durability of the mark. Here’s a detailed discussion and comparison:

Dot Peen Marking

Dot peen marking involves a pneumatically or electromechanically driven pin that rapidly indents the material surface with dots to create numbers, letters, logos, or 2D Data Matrix codes. The resulting mark is a series of closely spaced dots forming lines or shapes.

This type of marking is widely used in automotive, metalworking, and aerospace for marking components where the durability of the mark is critical. This can range from the process of adding serial numbers on engine parts to VIN numbers and tool identification.

Dot peen is often preferred for harder materials and where surface deformation is not a concern, whereas laser marking offers broader material compatibility and is better for delicate or heat-sensitive materials.

Advantages of dot peen marking include:

  • The marks are deeply embedded into the material, making them highly durable and resistant to wear over time, even in harsh environments.
  • Generally less expensive than laser marking systems, both in initial investment and maintenance costs.
  • Effective on a wide range of materials, including metals, plastics, and harder materials.

Disadvantages of utilizing dot peen marking include:

  • Typically slower than laser marking due to the mechanical process of indenting each dot.
  • The mechanical impact may deform delicate parts or surfaces.
  • While precise, it may not achieve the fine detail possible with laser systems, especially on very small or complex designs.

Laser Marking

Laser marking uses a high-intensity light beam to slightly alter or ablate the surface material, creating high-contrast marks without contacting the material.

Techniques include engraving, annealing, etching, and foaming, depending on the material and desired effect.

Laser marking wins in precision and detail, making it preferable for industries requiring intricate designs or small text. It is considered ideal for barcodes, UID codes, QR codes, and detailed logos.

 

 

Laser marking is commonly used in:

  • Electronics
  • Medical devices
  • Aerospace
  • Jewelry
  • Applications where precision, minimal part damage, and aesthetic quality of the mark are paramount.

Three main advantages of laser marking are as follows:

  • Capable of producing highly detailed, precise marks with excellent resolution. Suitable for small text, complex logos, and even photographic images.
  • Can mark a wide range of materials, including metals, plastics, ceramics, and even sensitive materials without damaging them.
  • Fast marking process due to the non-contact nature of the laser, which can move quickly over the target surface.
    Easily programmable for variable data (e.g., serial numbers), integration into production lines, and minimal maintenance.

Meanwhile, some disadvantages of this marking system include:

  • Higher initial investment and operating costs compared to dot peen marking
  • Safety precautions necessary due to the use of high-powered lasers
  • Certain materials may not mark well or require specific laser types (e.g., fiber, CO2, UV) to achieve the desired contrast or effect.

Note: The size of the parts can also be a factor, as even huge parts can easily be marked with a handheld dot peen marking system, while lasers are not developed to the point they can be utilized for large parts.

Comparing Dot Peen and Laser Marking

Laser marking offers unparalleled precision and flexibility for a wide range of materials and applications, while dot peen marking provides a cost-effective, durable solution for simpler marking tasks.

The choice between dot peen and laser marking ultimately depends on the specific requirements of the application, including:

  • The type of material
  • The desired mark quality and durability
  • Production speed
  • Budget constraints

Marking System Choices | Next Steps

Laser marking and dot peen marking are both widely used in industrial applications for the permanent marking of parts and products, but they differ significantly in their mechanisms and outcomes.

Laser marking utilizes a high-intensity light beam to etch or mark the surface of a material, allowing for precise, high-resolution marks including barcodes, QR codes, and intricate graphics, while dot peen marking involves a pneumatically or electromechanically driven pin that physically impacts the surface to create dots forming numbers, letters, or simple logos. Both are useful in any number of industries – depending the needs and expectations of the product line in question.

Dot Peen Marking Basics

What Is Dot Peen Marking?

, , , , , ,

Dot Peen Marking Basics

Ask anyone inside the industrial manufacturing industry – part-marking is crucial to component traceability when working with large quantities. And while several different types of part-marking exist, Dot Peen marking technology has been a preferred solution for many years. 

At a high level, Dot Peen marking machines use either electromagnetic or pneumatic force to rapidly oscillate a stylus, in turn indenting the marks onto the surface of the part. 

One of the advantages of Dot Peen is that it’s very flexible and can be used in either manual or fully automated production lines. A lot of the applications Dot Peen serves are manual applications, however, with modular Dot Peen systems, you can start with a portable system and later convert it to an in-line system for integration with fully automated production lines.

 

The Basics | What is Dot Peen Marking?

If you took apart a Dot Peen machine, one of the most important components you would find is a carbide or diamond-tip stylus. 

The Dot peen process is considered a “low-stress” marking method because the mark is generated via material displacement rather than material removal.  The carbide stylus strikes the material surface to produce the mark via a series of cold-formed stamped dots. Compared to Laser Marking Systems, Dot Peen does not induce thermal shock to the part surface since the material is cold-stamped rather than super-heated to produce the mark.  

Dot Peen systems are commonly used by manufacturers in the aerospace and oil & gas industries where low-stress marking is required, such as tubular and flow control products that are exposed to extreme pressure differential in the oilfield. 

Dot Peen marking is viable for material hardness up to 63 HRC. Typically, when a part hardness is greater than 63 HRC, laser marking systems are recommended. 

All of Technomark’s Dot Peen machines rely on an electromagnetic solenoid to actuate the marking stylus. Dots are plotted in an X/Y plane via electronic control for precise placement of the Dot pattern. Using electromagnetic force versus pneumatic also provides a greater level of control of both the depth of the mark as well as the ability to mark contoured or complex surface.

Dot Peen Marking: Component Traceability In Action 

Dot Peen marking machines are utilized in almost every industrial-goods manufacturing operation, including: 

  • Automotive
  • Oil and Gas (pipes, fittings valves, other)
  • Aerospace
  • Defense
  • Metalworking (general purpose)

Dot Peen Marking 101

While these machines can run in-line and handle large quantities in an automated production environment, most are operated manually using a battery pack to go mobile. 

The best Dot Peen marking machines utilize a fully electric design and that doesn’t require compressed air to operate.  All Technomark Dot Peen marking machines feature an Intelligent Driving Impact (IDI) function that allows for marking on many different materials and finishes. The IDI function automatically adjusts and levels the stylus to the workpiece. Whether the part has a curved, wavy, or complex geometry, the stylus will follow the contour of the marking surface while maintaining a constant depth of high-quality marking throughout. 

When structural integrity is crucial, Dot Peen marking provides a low-stress marking solution that removes no material during the part marking process.

Why Choose Dot Peen Marking

One of the biggest benefits of a Dot Peen Marking Machine is its ability to efficiently produce marks compared to other marking systems. Other benefits of Dot Peen machines include: 

  1. Portability: battery-operated systems are ergonomic and perfect for smaller-scale operations or marking of large, heavy parts that cannot be transported to a fixed location for marking
  2. Versatility: state-of-the-art Dot Peen marking systems are modular and can start with a portable or manual marking system that can later be adapted to a fully automated production line
  3. Ease of use: Dot Peen machines are easy to program and do not require any advanced computing knowledge or technical training. 
  4. Permanency: Dot Peen marking process yields a permanent, indelible mark that can withstand harsh operating environments
  5. Economical: Compared to other marking systems, Dot Peen systems are typically less than $10,000.

Integrating a dot peen marking machine into your production line will improve the productivity and quality of the part-marking process.  

New and exciting dot peen innovations are coming this fall. Be on the lookout for machines that feature: 

  • Wireless connectivity between marking head and control (Network-able devices that are able to communicate to other devices through wireless communications)
  • On-board diagnostic tools to help the operator know when it’s time for scheduled maintenance — protecting your investment.

Direct Part Marking 101 | Automotive Component Traceability

, ,

The number of components used to manufacture vehicles has doubled over the past decade. This means more parts to 

  • keep in inventory
  • track during production 
  • evaluate throughout the life cycle to pinpoint issues 

Automotive part marking requirements are intended to help with all of the above processes. This means accuracy and readability are crucial for the purpose of laser marking automotive parts, and it doesn’t hurt to have a process that makes traceability easier. 

 

Meeting Automotive Industry Standards

The automotive industry is duty-bound to provide safe and reliable vehicles to consumers. With new models of integrated marketing equipment and technology introduced each year, it’s important to have a method of tracking parts when issues arise and a recall becomes necessary. 

In recognition of the importance of recalls and safety, the automotive industry has set high standards for product identification. Automotive parts identification is required, but it also provides several benefits: 

  1. A product can be marked with serial and part numbers, barcodes, and other information. 
  2. Items can be tracked throughout their entire lifecycle.
  3. No need for traditional labels prone to fading or falling off. 
  4. By using 2D barcodes, manufacturers can identify very small items and parts and include more data than in a linear barcode.
  5. Improved error prevention for just-in-sequence (JIS) production.
  6. Reduced risk of counterfeit parts because part marking is difficult to duplicate.

Part marking is a process used to identify automotive components, improving quality control throughout the production and life cycle of a vehicle. With vehicle components increasing and shrinking at the same time, automotive part marking becomes ever more important in order to properly track and evaluate all these components.

Traceability is also an important factor when it comes to automotive part marking, as it helps determine where each component came from and how it was made. 

As such, accuracy and readability are essential for automotive part marking to be useful for the manufacturer With the right part identification methods in place, automotive manufacturers can:

  • Meet industry standards
  • Ensure the safety and reliability of their products
  • Improve future designs

JIS production is a technique where parts are delivered to the assembly line in a manner that perfectly synchronizes with the automotive manufacturing process. Timely and precise delivery allows automotive manufacturers to make efficient use of their resources while also reducing costs. Automotive part marking plays an important role in JIS production by minimizing and ensuring production runs smoothly.

 

The Importance of Traceabilityautomotive component marking

The automotive industry is relying more and more on automotive traceability requirements to ensure the quality and safety of its products. Part marking requirements are essential in helping automotive companies trace, manage, and evaluate components over the entire life cycle of a vehicle.

The implementation of direct part marking has:

Automated process control systems require accurate data input for maximum efficiency, and part markings help provide that accuracy. Additionally, integrated marking equipment along the automotive production line can read and store this data to optimize the build and speed up production.

Chain of Custody Tracking Improvements

Automotive companies that use part marking are able to correctly fulfill customer requirements. Strong chain of custody tracking and the ability to avoid product diversion helps automotive companies deliver quality parts on time and keep track of what goes where in case problems arise.

 

Dot Peen vs. Laser Marking Automotive Parts

There are numerous methods of direct part marking that can be used for parts exposed to harsh conditions, such as vehicles that traverse a variety of terrains. Dot peen marking and laser marking are two popular methods used in the automotive industry. Both have advantages and disadvantages to consider before committing to the investment associated with your preferred method. 

Dot Peen

Dot peen is a method that involves striking the metal or product material (typically metal) with a marker that knocks away a small amount of material to leave a readable mark.

Advantages of dot peen marking include: 

  • Lower cost.
  • Durable and permanent mark
  • High marking speed
  • Minimal stress (mechanical only)

The disadvantages of dot peen marking include limited usefulness. In terms of materials, this method is effective for metal and plastic, but not others. The dot peen marking process also exposes parts to mechanical stress, which can weaken the component and increase the risk of part, and has the potential for increasing the occurrence of defects. 

The M4 inline and automation pack can help optimize marking for automated production: https://www.technomark-inc.com/solutions/integrated-use/m4-inline/  

Laser Marking
Laser marking is a non-contact method that marks parts using a precise beam. The Direct Part Marking laser has a higher rate of permanency and accuracy.

Other advantages of laser marking include:

  • Permanent & accurate mark
  • High-Quality mark that can be applied to many materials
  • Can be done at high speeds; high contrast
  • Resistant to heat and liquids

However, there are disadvantages to recognize as well. These include both higher costs for a laser marking device and issues when materials are exposed to mechanical stress. The energy cost for the laser in question depends on the type used.

Understanding the Differences Between Data Matrix vs QR Codes:

, , , ,

If you’ve ever opened a new electronic device, tool, or home appliance, chances are you’ve seen a Data Matrix code.

While you may have thought it was a QR code, Data Matrix codes are an essential part of most manufacturing processes and act as an efficient means for component traceability. Data Matrix codes are also the only 2D barcode to have GS1 approval for regulated healthcare items. 

QR codes on the other hand are larger and contain more data, such as website URLs, and are capable of encoding information not just in numeric and alphanumeric form, but also in Kanji and other multi-byte character sets. 

No matter what industry, when it comes to industrial traceability for manufacturers, choosing the right type of code can leave a production run riddled with misinformation and the chance of getting lost. 

Let’s break down the differences and similarities between QR and Data Matrix codes and why the latter is the preferred choice of the majority of manufacturers.  

 

Direct Part Marking | QR vs Data Matrix Codes

While both QR and Data Matrix codes are in the public domain and can be used royalty free, Data Matrix codes have become the standard for anti-counterfeit measures, part identification, and internal tracking because they feature advanced error-correcting techniques that are more robust than QR codes. 

This presents a unique benefit for manufacturers that need to ensure their products can be identified if part of the mark gets damaged or impeded. 

Particularly necessary for complex and high stakes industries such as medical, aerospace, and defense, where hundreds to thousands of components are needed in order to assemble a finished product, Data Matrix codes can be read even if up to 50% of the mark gets damaged. 

QR codes on the other hand have steadily been adopted in consumer-facing applications. These codes can be found everywhere from business cards to product packaging, containing links to websites, resumes, premium offers, and even restaurant menus. 

QR codes have a lower level error-correcting built in, and can be rendered useless with even slight ware and tare. Just 30% of a QR code needs to be damaged before it becomes unreadable. 

While these codes are perfect for consumer-forward use, marking a component or part with a QR code presents a real danger for misidentification pending the mark gets damaged.

Specifications of Data Matrix vs QR Codes

While Data Matrix codes are typically reserved for industrial use cases, both types of marks can play a role in the manufacturing industry.

Since both DataMatrix and QR codes are GS1 approved, they can carry any GS1 ID keys including: 

ID Key
Global Trade Item Number (GTIN)
Global Location Number (GLN)
Global Returnable Asset Identifier (GRAI)
Global Individual Asset Identifier (GIAI)
Global Service Relation Number (GSRN)
Component/Part Identifier (CPID)
Global Model Number (GMN)
Used to Identify
Products and services
Parties and locations
Returnable assets
Assets
Service provider
and recipient relationships
Components and parts
Product model
Example
Can of soup, chocolate bar, music album
Companies, warehouses, factories, stores
Pallet cases, crates, totes
Medical, manufacturing, transport and IT equipment
Loyalty scheme members, doctors at a hospital, library members
Automobile parts
Medical device

 

Beyond GS1, specifications and requirements for each code are presented by the International Organization for Standardization (ISO). For more about how these codes work themselves, and how to create them, you can check out the relevant ISO standard for more detail.

Requirements for Data Matrix codes are specified under the ISO/IEC 16022 international standard; while requirements for QR codes are specified under the ISO/IEC 18004 international standard.
