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.

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)

Laser Etching vs. Engraving: What to Know

, ,

Laser marking, also known as laser engraving or laser etching, is a precise and permanent method of adding marks or designs to various materials. It uses a high-intensity laser beam to alter the surface of the material, resulting in marks that can range from logos and text to intricate patterns.

With both etching and engraving, precision and permanence are key. Whether you’re in the business of personalizing gifts or manufacturing industrial parts, choosing the right laser marking technique can make all the difference. When considering the two primary methods, laser etching vs. engraving, both provide accuracy but only one can lead to the right final product, depending on your goals. 

While laser etching and laser engraving are terms that are used interchangeably, there is a notable difference between the two laser marking processes: the depth of the mark left on the product. When laser etching is used, the mark is typically 0.0001”, while laser engraving 0.0001-0.0005” in depth. Meanwhile, deep engraving is considered any mark deeper than 0.0005”. 

Another difference between the two is the process of creating the mark itself. While laser etching uses a beam of focused light, laser engraving uses a rotating lens to direct incoming beams to the surface of the product to create the mark. 

Choosing the right method for your needs can depend on other factors than the process itself, including: 

  • Material being marked
  • Environment 
  • Setup costs
  • Wear and tear on materials
  • Speed
  • Precision

 

What is Laser Engraving?

Laser engraving is an art form that can be seen in many different materials, from metal to wood and plastic. It is a delicate process that requires extreme precision, as the smallest mistake can ruin a project or result in permanent damage to the material. The technique works by using a high-powered laser beam to vaporize or cut away thin layers of the material being engraved, much like sandblasting, but with more control and accuracy over depth and shape. This allows for high contrast marks to be added with amazing precision, resulting in clean lines and smooth surfaces. Additionally, with the right equipment and setup, laser engraving can be done quickly without sacrificing detail or accuracy.

This makes the laser engraving process perfect for projects where exact detail is required, such as commercial part marking for medical implants or industrial parts. In these cases, choosing the right laser marking technique can make all the difference; not only will it give you better results but it can also save time and money on production costs.

 

Pros and Cons of Laser Engraving

Laser engraving offers a lot of advantages over other methods such as sandblasting or chemical etching. One of the greatest advantages is speed; laser engraving can be done much quicker than traditional methods, allowing for high production rates when dealing with large amounts of parts. Additionally, laser engraving provides more control over the depth and shape of the engraved area, allowing for intricate details to be added with amazing precision.

With laser engraving, accuracy and replication are extremely important. The speed of the process is also a great advantage as it allows for quick turnaround times on orders. Laser engraving can be used to add text, logos, or other images to items quickly and with amazing precision. Additionally, because it’s non-contact, there are no worries about wear and tear on the parts like with traditional methods.

However, there are some limitations to keep in mind when using laser engraving. The process is limited to certain materials that can absorb the energy from the laser beam without being damaged. Metals such as aluminum and stainless steel are common choices, but other materials like glass and plastic can also be engraved. Additionally, laser engraving can be expensive to set up since it requires specialized equipment and the cost of laser engraving varies depending on the complexity and size of the job. Large jobs can take longer to complete and require more equipment or materials which can add to the overall price tag. 

It’s also important to consider the environment when using laser engraving. The process generates fumes and particles that can be hazardous if proper ventilation is not present. Wearing protective gear, such as safety glasses and gloves when operating the laser in order to protect against eye damage or burns, is also a best practice. Lastly, lasers require constant maintenance and adjustments in order to stay operational. This can add up over time so it’s important to factor that into cost estimates.

 

What is Laser Etching?

Laser etching is a surface alteration process that uses a laser beam to create an indelible mark on a variety of materials. It’s widely used in industries such as product manufacturing, packaging, and labeling for branding, customization, and personalization. In some cases, it can also be used for decorative purposes like creating intricate designs on wood or other surfaces.

Laser etching works by using intense beams of light to penetrate the surface of the material and create very fine lines or tiny holes. The laser etching process can be controlled with precision allowing for deeper engraving or shallower marking of the material’s surface. This makes laser etching incredibly versatile as it can be used to mark various materials with different depths, whether for promotional purposes or decorative effects.

 

Pros and Cons of Laser Etching

Laser etching is ideal for making unique designs on surfaces with precision and accuracy. For example, jewelry designers can use laser etching to engrave special messages or patterns on rings, earrings, and other pieces of jewelry. 

Laser etching is an incredibly versatile tool in many different industries thanks to its precise marking capabilities and compatibility with different materials. However, laser etching is typically not the best method to use for marking parts in the automotive industry. This is because most parts are made of metal that require a more heavy-duty engraving method such as deep-cut or rotary engraving. 

The strength and longevity of these methods make them a better choice for long-term applications, especially in areas where high temperatures can cause regular laser etching to fade easily. Additionally, deep-cut and rotary engravings can create very intricate designs and shapes much more effectively than laser etching can.

 

Laser Etching vs. Engraving | Next Steps

Choosing the right method for creating marks on your product requires attention to the speed needed, the material being marked, the precision, and other factors. With these criteria in mind, choosing the right method for optimal efficiency is manageable.

Marking solutions featuring this technology can provide flexibility in terms of font size, typeface selection, and line spacing. The M4 Inline makes it easier to configure this system for optimal performance when integrated correctly into the existing production line.

 

Overview of Industrial Marking Systems

Industrial marking systems come in many varieties, allowing for flexibility and scalability depending on the size of the product being marked. Common types of industrial marking systems include:

  • Dot peen marking is a popular choice for parts that require permanent marks in various materials such as steel or aluminum. This type of system uses mechanical pins to create marks into the surface of the material with an automated motion. The versatility of dot peen makes it suitable for many applications such as serial numbers, logos, images, text, and barcodes.
  • Laser engraving is another effective way to mark parts such as stainless steel or plastic; this type of system uses a high-powered laser beam to precisely remove material from the material’s surface to create desired markings. It can also be used for deep impressions that are permanent and tamperproof.
  • Thermal transfer printing involves using a combination of heat and pressure to press ink onto the material’s surface to create a clear image or text that will not fade over time. This technique is an excellent choice for complex designs that require crisp resolution quality with durability against environmental wear and tear.
  • Inkjet printing uses high-pressure jets of liquid ink to deposit tiny droplets onto surfaces to create readable characters and images with vibrant colors and resolutions up to 600 dpi or more. This method is ideal for creating intricate design elements and detailed logos in short production runs with minimal setup times.

 

Applications of Industrial Marking Systems

Traceability and product identification are essential in a wide range of industries, from food and beverage production to medical device production to automotive manufacturing. Product traceability is the process of tracking each item through the life of its production process. This enables real-time monitoring of products, making it possible to identify exactly where they came from and when, as well as who handled them.

Traceability allows companies to have an accurate audit trail in case of recall or fraud, enabling them to quickly and effectively trace the source of any defective items.

Product identification helps companies differentiate their products from competitors by creating unique identifiers like barcodes or serial numbers for each item produced. These can be printed on labels using industrial marking systems such as thermal transfer printing or inkjet printing.

Product identification also ensures that each item can be properly identified during assembly and throughout its whole life cycle, enabling more efficient inventory management and ensuring accurate record-keeping for regulatory compliance and customer safety.

Compliance labeling is the process of marking products to show the product has passed certain safety and quality standards. These products meet certain standards, such as those imposed by regulatory bodies like the Food and Drug Administration or industry associations like Underwriters Laboratories.

The need for compliance labeling by industry is twofold:

  • It provides customers with the assurance that products meet at least certain minimal safety and quality criteria
  • It can protect companies from liability in the event of something going wrong. For example, if a product does not comply with applicable safety standards or fails to meet a customer’s expectations, then the company may be held liable if evidence of their compliance labeling can be proven.

Companies, therefore, have an incentive to properly label their products in accordance with applicable safety and quality regulations.

Part marking methods can also play an important role in the branding and promotional marketing of a product or company. By using a unique part marking system, companies are able to differentiate their products from competitors through a recognizable and memorable logo, while also ensuring that the safety and quality standards required for compliance labeling are met.

Unique part marking systems can help to create a strong brand identity by providing customers with an easy way to identify a certain product as belonging to the same company or family of products. Additionally, part marking processes can be used in promotional campaigns as well, such as when running contests or giveaways that require customers to identify specific parts. In this way, companies are able to both promote their products and ensure that they comply with applicable regulations at the same time.
