In the realm of industrial marking and engraving, Accumark Inc, located in Hudson Wisconsin, is a leading job shop that provides fiber laser marking. This type of laser marking has emerged as a preferred technology due to its precision, speed, and versatility. This technique involves using a fiber laser to create permanent marks on various materials, offering an array of applications from product identification to decorative engraving.
What is Fiber Laser Marking?
Fiber laser marking uses a concentrated beam of light from a fiber laser to alter the surface properties of materials. Unlike traditional marking methods that might use inks or mechanical etching, fiber lasers achieve marks through several processes:
- Annealing: Changes the color of the surface by creating an oxide layer on metals.
- Engraving: Removes material to create a physical indentation.
- Color Marking: Alters the color of the material, often used for aesthetic purposes or to increase contrast.
The process is non-contact, meaning there’s no wear and tear on the marking tool itself, leading to consistent quality over time. The laser’s beam is controlled by computer software, allowing for intricate designs and precise text placement.
Advantages of Fiber Laser Marking
High Precision: Fiber lasers can produce marks with incredibly fine detail, down to microns, ideal for barcodes, QR codes, and serial numbers.
Durability: Marks made by fiber lasers are permanent and resistant to environmental factors like heat, chemicals, and wear, making them suitable for traceability in harsh environments like automotive manufacturing or aerospace.
Versatility: These lasers can mark a wide range of materials including metals, plastics, ceramics, and even some coated materials. Each material might require different settings for optimal marking results.
Speed and Efficiency: Fiber lasers operate at high speeds, reducing production times significantly. They also require less energy compared to other laser types, contributing to cost efficiency.
Low Maintenance: The design of fiber laser systems, with fewer moving parts and no need for consumables like ink, means lower maintenance costs and downtime, and faster production times.
Applications of Fiber Laser Marking
Fiber laser marking technology has found applications across numerous industries, here are some sectors that Accumark Inc provides laser marking services for:
- Electronics: Marking PCBs, connectors, and electronic components for traceability and branding.
- Jewelry: For aesthetic engraving, personalization, and anti-counterfeiting measures on precious metals.
- Automotive: Permanent marking of engine parts, brake components, and chassis numbers for identification and safety.
- Medical Devices: Marking serial numbers and batch codes on surgical instruments that need to withstand sterilization processes.
- Food and Beverage: Safe, non-toxic marking on packaging for lot numbers, expiration dates, and branding without affecting the product’s integrity.
- Aerospace: Part marking and serialization of parts is key for many application in the Aerospace sector.
How Does Fiber Laser Marking Work?
The core of fiber laser marking lies in the laser’s ability to focus light through an optical fiber. Here’s a simplified breakdown:
1. Laser Generation: Light from laser diodes stimulates a gain medium (often Ytterbium-doped fiber) inside the laser system, amplifying the light into a coherent laser beam.
2. Beam Delivery: The beam is then directed through fiber optics to the marking head, where it’s expanded and focused by lenses onto the workpiece.
3. Marking: As the beam interacts with the material, it either removes material (engraving), changes the surface color (annealing), or alters the surface in other ways depending on the material and settings used.
4. Control via Software: The entire process is controlled by software that dictates the pattern, speed, and depth of the marking, allowing for intricate designs or simple text.
Choosing the Right Fiber Laser Marking Machine
When selecting a fiber laser marking system, consider proper placement in a shop/work environment. Highly trained programmers and laser technicians with the proper skills to are a must to run fiber lasers. Costs for fiber lasers can also be expensive for a system that can accommodate a wide variety of substrate uses. Here are some things to keep in mind:
- Material Compatibility: Ensure the laser wavelength is suitable for your material.
- Power and Speed: Dependent on your production needs; higher wattage allows for deeper engravings but might not be necessary for surface marking.
- Software: User-friendly software with capabilities for creating and editing marks directly can significantly influence productivity.
- Safety Features: Given the intensity of the laser, safety features like enclosure and protective eyewear are crucial.

Environmental and Safety Considerations
Laser marking reduces waste compared to traditional methods, as there’s no need for inks or chemicals. However, always consider:
Fume Extraction: Some materials might emit fumes or particles when marked, necessitating proper ventilation or extraction systems. All laser systems require fume extraction!
Eye Protection: Both for the operator and any personnel nearby due to the potential for eye damage from direct or reflected laser beams. Some laser systems are enclosed, while many are not.
Conclusion
Fiber laser marking stands out for its efficiency, versatility, and the quality of marks it provides. Whether for branding, traceability, or functional purposes, this technology offers solutions that are permanent, high-quality, and cost-effective. As industries continue to evolve, the adoption of fiber laser technology for marking will likely grow due to its adaptability and the continuous advancements in laser technology itself.
