6 Tips for Choosing the Best Laser Marking System for Your Business Needs

, ,

Laser marking systems provide reliability and long-term marking solutions for commercial and industrial applications, which resolves concerns about component tracking for many industries where the product is exposed to extreme heat or other conditions that cause wear and tear.

Choosing the best laser marking system for your production line means weighing the various factors that determine the most effective yet least time-consuming process to meet deadlines.

We compiled a list of six actionable tips to choose the most suitable laser marking system:

  1. Understand your marking needs
  2. Consider the type of laser technology
  3. Evaluate system performance and speed
  4. Assess software compatibility and ease of use
  5. Consider maintenance and durability
  6. Compare costs and return on investment

1. Understand Your Marking Needs

The use of laser marking systems is not the only choice to be made. Within the laser marking industry, various methods have been proven effective for product marking. The process to use depends on a variety of factors. Three marking methods that utilize lasers include:

  • Engraving: With laser engraving, marks are made on the surface of an object with high heat that vaporizes the material into dust. This is done quickly and with precision, allowing for unmatched durability and readability, along with better turnaround times on orders that involve a large number of parts.
  • Annealing: This process changes the color of the metal but does not remove any materials. This is because oxygen is diffused beneath the surface of the metal during a slow heating process. This process is only useful for metals like steel, stainless steel, and titanium.
  • Etching: In this process, heated surfaces are allowed to expand, creating permanent marks in a faster and more efficient manner. This process provides a contrast that remains readable after post-treatments.

Different marking applications are ideal for different material types. For example, certain metals can be marked using the annealing process (as noted above). Meanwhile, etching or engraving can be useful for metals, plastics, and some other materials – such as wood. However, the process used makes a difference in the marking quality, depth, and the speed at which the marking process is completed.

2. Consider the Type of Laser Technology

Several types of lasers are used in laser marking systems:
Fiber lasers use a shorter wavelength than the CO2 laser and are capable of marking non-metallic surfaces. This process is commonly used for plastics and metal, as well as rubber.

CO2 lasers can be used to mark wood, plastic, cardboard, as well as metal. This type of laser uses CO2 gas to create an infrared laser beam. This beam cuts the mark into the material.

UV lasers have an adjustable wavelength and can be used on sensitive materials. This process is also possible to complete cold marking – which protects the product from heat degradation but still provides a readable, long-lasting mark.

3. Evaluate System Performance and Speed

Both marking speed and system performance impact overall productivity. Marking speed can lead to a faster completion rate for a larger order, as noted previously. Meanwhile, system performance can mean consistent production rates over time versus a more chaotic rate of production due to maintenance-related downtime.

4. Assess Software Compatibility and Ease of Use

Laser software is commonly hard to understand and to use because of the settings (except for an expert). User-friendly software offers adjustments that can be completed quickly and with minimal clicks. A secure connection via WiFi means the laser marking system can be utilized anywhere the WiFi reaches across the facility – or outside if necessary.

This allows for marking in real-time and allows for maintenance to be adjusted through the software as well.

5. Consider Maintenance and Durability

While reliable systems might come with a higher initial cost, they often lead to significant savings over time. Reduced downtime, fewer repairs, and longer intervals between major maintenance can drastically lower the total cost of ownership. Also, there are no consumables for laser marking (which is a durability and environment advantage).

Reliability also ties into safety. Systems that are less prone to malfunction reduce the risk of accidents in the workplace, protecting both your employees and your equipment.

Systems designed with ease of maintenance in mind often have modular components that can be easily replaced or serviced. Easy maintenance also means that you can potentially handle many issues in-house without needing to call in expensive external service technicians every time something needs tweaking.

6. Compare Costs and Return on Investment (ROI)

Choosing the right industrial laser marking system is a significant decision that can affect your operation’s efficiency, safety, and bottom line.

When evaluating options, consider not just the purchase price but also the costs associated with maintenance, repairs, and potential downtime. A more expensive system might be more cost-effective in the long run if it’s more reliable and easier to maintain.

These can then be weighed against the potential for increased ROI, which can make the final decision easier to reach. Calculating ROI for laser marking machines takes all of the following into consideration:

  • Improved efficiency
  • Productivity rates
  • Product quality

Laser Marking Systems: Opting for Efficiency

Technology evolves, and so do the needs of your business. A system that is easy to maintain is generally more adaptable to upgrades and changes. This adaptability ensures that your investment remains valuable and relevant, even as new technologies emerge.

A reliable system delivers consistent quality in markings, which is critical for traceability, brand identity, and meeting industry standards. This consistency helps in maintaining product quality throughout the production cycle, reducing the risk of errors or defects. Finding that system means evaluating the above points and determining the most efficient system for your unique production needs.

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

Manufacturing Traceability Solutions: What Are The Options?

, ,

Anyone who works in manufacturing, whether it’s automotive parts or oil and gas equipment, knows that proper traceability is key to product success. 

Having proper identification information on your components isn’t just helpful for inventory and maintenance, it’s also a federal requirement for many industries. 

But what are the manufacturing traceability solutions on the market for permanent identification? Well, there are a lot of options, some better than others. Here’s the rundown:

Which Manufacturing Traceability Solution Is Best for You?

The ideal product traceability solution for you will depend on your industry, processes, and applications. For example, delicate components like solar panels will benefit from laser marking, while other heavy-duty parts can use dot peen marking. 

At the end of the day, the goal is to provide permanent and legible marking. Some of the most well-known methods include:

  • Dot peen marking
  • Laser marking
  • Inkjet marking
  • Impact presses
  • Chemical etching

Dot Peen Marking

Dot peen is a direct part marking method, meaning that the marking head of the machine interacts directly with the component to achieve a permanent mark that is able to survive harsh operating environments

Dot peen machines use an impact stylus to create small indents on a part’s surface to create letters, numbers, logos, or  2D datamatrix codes. Because the mark is formed via material displacement instead of material removal, it is considered a low-stress marking technique ideal for aerospace as well as oil and gas applications.

This method of marking is compatible for complete automation The marking head can be integrated inline for high-volume production lines and requires minimal operator intervention.

Dot peen marking equipment is also well-suited to manual marking operations. It can mark large or hard-to-reach parts, especially if you’re using a hand-held dot peen machine. Plus, dot peen is compatible with a wide range of metal materials, including steel, iron, and aluminum.

Laser Marking

Laser marking is one of the most widely used manufacturing traceability solutions because of its versatility. The mark is achieved by super-heating the part surface to etch, ablate, or anneal the material substrate Target applications that are ideal for laser marking include:

  • Wide range of plastics
  • Ferrous and non-ferrous metals
  • Elastomer compounds
  • Organic materials (like wood or cardstock)

The laser marking system is ideal for high- or low-volume production capable of marking  high quality 2D data matrix barcodes and alphanumeric text to logos and graphics. 

Other benefits of laser marking include:

  • Compact design
  • Flexibility
  • Advanced, yet simple programming
  • Capable of full automation
  • 3D part marking
  • Solid state design
  • No consumables cost

While dot peen marking requires the stylus to make contact with the product, laser marking is a non-contact traceability method. This makes the laser better adapted to marking complex geometries or delicate materials. 

Inkjet Marking

While dot peen and laser marking systems provide a permanent traceability solution, inkjet marking is semi-permanent. 

Inkjet marking functions a lot like a regular printing machine — using drops of ink to mark information on a substrate. It’s often regarded as one of the fastest marking methods, and is capable of marking on:

  • Wood
  • Rubber
  • Concrete
  • Textiles

The downfall of inkjet marking is that it’s only semi-permanent. High levels of wear and tear or exposure to harsh environmental conditions can wear away the marking. As such, inkjet marking is usually used for consumer goods packaging, where the mark only needs to survive the short life of the product.

Impact Press Marking

Just like dot peen marking, an impact marking press indents a material with the desired identification information. However, the methods are different. 

Whereas dot peen marking uses a series of cold-stamped dots to mark text, 2D data matrix codes, or logos into a material, the impact press uses a die to stamp the information instead. 

The process is similar to a letterpress, where characters are arranged in a certain order and then stamped onto the substrate. But with impact marking, the tooling is applied with enough pressure to indent the material. 

A mechanical impact punch is versatile, capable of other manufacturing operations like coining or bending materials. However, the process isn’t digital (meaning the information is not dynamic) and has higher tooling and maintenance costs than other methods of marking. 

Chemical Etching

Chemical etching takes a completely different approach to direct part marking. This method uses chemical compounds to subtract materials from the marking surface via a process of electrolysis to create the impression. 

Chemical etching is essentially an accelerated form of oxidation. A stencil is soaked in an electrolyte solution and applied to the material. A low-voltage electric current is then applied to the stencil to initiate the oxidation process. 

Chemical etching requires several steps to prepare the part for marking, but it’s a cost-efficient and quick process. It’s also less invasive than other marking methods, making it ideal for thin-wall parts.

However, chemical etching, like the impact press, is not a digital process. The information on each stencil is fixed, so you’ll need unique stencils for each different marking. On the upside, the materials involved are low cost. Chemical etching is ideal for low-volume applications such as prototyping. 

This method of marking is mainly used for metal substrates like steel, aluminum, or nickel alloys. If you’re looking for marking on plastic or rubber, laser marking might be a better option.
