Laser Engraving Braille|Certification of Braille Laser Marking

This site focuses on the technology of controlling the height of Braille dots produced by laser engraving, as well as the process of certification. It provides professional technical analysis, interpretation of industry standards, and a guide to the certification process.The content covers laser parameter optimization, methods for detecting tactile accuracy, and key points for applying for international certification (such as ISO 17076). The center helps manufacturers improve the quality of their braille labels, ensuring that their products comply with regulations for accessibility, and reducing production risk.

The laser engraving technique for Braille uses a high-precision laser to form raised dots on a surface that can be felt by touch. The height of the dots directly affects the readability and safety of the Braille markings.Because of strict requirements on the height of the Braille dots (0.2-0.5 millimeters) in different countries, the laser power, frequency, and scanning speed must be adjusted according to material properties during manufacturing to ensure that the product meets the standard.

Compliance certification is a key step in getting a product into the market.For example, the ISO 17076 standard requires the following tests: sample testing, durability testing and assessment of consistency of feel.Companies must submit complete technical documents, including laser parameter setup tables, quality inspection reports, and environmental adaptability data.Common problems include excessive fluctuations in height (for example, caused by heat deformation leading to a decline in the height of the dots) or burrs at the edges of the dots that affect the feel. These problems can be solved through pre-compensation algorithms and inert gas-assisted processing technology.

This special report also examines the requirements for Braille signage in the Americans with Disabilities Act (ADA) in the US, and the EN 301549 standard in Europe, and provides a list of recommended self-test tools (such as 3D profilers and tactile feedback testers).For small and medium enterprises, it is recommended that they select a third-party testing agency that has been certified by CNAS, so as to shorten the period of certification.Finally, the book provides case studies of laser marking on a variety of materials, including metal, plastic, and leather.

Optimizing Braille Laser Engraving Parameters

The team also developed a set of parameters for laser printing of braille, which can be used with a reference chart to quickly adjust the laser power.It includes information on the relationship between different materials, the height of the Braille dots and the power setting, helping the operator to set the parameters precisely, thereby improving the efficiency and quality of the marking process.This is a reference book for engineers who design and produce Braille labels.

Global Braille Signs: A Comparison of Standards

It will provide an in-depth analysis of the 2024 update to the International Standard for Braille Signs and Labels, and compare the differences between the standards used in Europe, America, and Asia. It will also provide practical advice on how to go from understanding the regulations to putting them into practice.This includes guidelines for public space signage, materials selection, and installation, to enable designers, architects, and accessibility service organizations to quickly grasp the latest compliance standards.

A Guide to Braille Dot Height Testing

This book provides a guide to the selection and use of braille dot height measuring instruments, covering comparisons of different types of equipment, points to consider when making a purchase, and operating techniques. It helps users quickly master key points, and improve the efficiency of quality checks on printed braille.

Five common mistakes that can lead to failure in a Braille certification inspection--have you fallen into any of these traps?

Certification of Braille is a necessary step for factories that produce products with identification labels, but many companies fail repeatedly because of oversights in the details.A summary of the five most common mistakes made in the certification process includes layout errors in the labeling, improper choice of materials, and a lack of quality control. This helps companies quickly identify and eliminate potential problems and increase their chances of getting certified.

Laser Marking Machines: Maintaining the Sense of Touch

Sharing the core technology for maintenance of laser engraving machines, the key to solving the problem of Braille embossing weakening over time.Through daily cleaning, recalibration, and environmental control, the company helps users extend the life of their devices, ensuring that the Braille markings remain clear and stable, and improving the user experience.

How to resolve the height difference between metal and plastic dots?

The raised dots on metal and plastic surfaces are made in different ways, and this often leads to problems with differences in height.By analyzing the characteristics of materials, processing techniques, and tactile optimization schemes, we can provide practical solutions that meet the standards for the height of Braille dots, helping to resolve the problem of tactile recognition of Braille on metal and plastic. This will ensure the effectiveness of the barrier-free facilities.

Blind to the Law: The Process of Testing Braille Signs for Compliance

This book provides a comprehensive guide to the process of testing for ISO certification, including standards, testing procedures, and common problems.They help public places and service institutions meet the technical specifications of Braille signs, such as the material and the spacing of the dots, so that they can pass certification reviews and create a truly barrier-free environment.

Braille Labeler Parameters: How to Accurately Control the Height of the Dots

The height of the dots on a Braille label directly affects the quality of the tactile experience.In three areas-pressure, material, and temperature-the company provides detailed information on how to adjust the machine's parameters to solve problems such as unevenness and wear of Braille dots, ensuring that the printed Braille meets international standards.
