In the tire manufacturing industry, the characteristics of tire texture play a crucial role in tire performance. High-precision measurement of tire texture is the key to continuously improving tire quality and optimizing design. In this context, white light interference 3D profilers are becoming an indispensable measurement tool.

Traditional tire texture measurement methods often have many problems such as lack of accuracy, difficulty in comprehensively acquiring 3D data and complexity of the measurement process. The white light interference 3D profiler stands out with its unique advantages.

From the working principle, the illumination beam of the white light interference 3D profiler is divided into two beams by a half-reflective and half-transparent beam splitter, which are projected onto the surface of the tire texture and the surface of the reference mirror respectively. The two beams of light reflected from these two surfaces interfere with each other, and by detecting the information of the interference fringes, the relative heights of the tire surface texture can be calculated with extreme precision, thus constructing a high-precision 3D contour image.

In terms of accuracy, it can achieve nanometer-level resolution, and can accurately capture those structural variations and height differences in the tire texture that are as subtle as a few nanometers. Both the complex depth and width of the main drainage grooves on the surface of the tire and the distribution of intervals between them, as well as the extremely fine and minute texture and angular structure of the tread blocks, can be clearly rendered.

In terms of measurement efficiency, it has the ability to image quickly, scanning and imaging an area of the tire texture in just a few seconds and analyzing the results automatically. And through its supporting software system, it can realize the automated splicing of the entire tire surface texture measurements, greatly reducing manual intervention and operation time.

For the R&D field, engineers using the high-precision data obtained from white light interference 3D profiler measurements can deeply analyze the relationship between tire texture design and key performance indicators such as tire grip, drainage performance, noise level, and abrasion resistance. Elements such as texture layout, depth and shape can be continuously optimized in new tire designs.

In the production quality control process, through sampling and testing of mass-produced tires, problems in the tire texture production process, such as texture deformation due to mold wear and missing texture due to uneven filling of rubber materials, can be detected in time. Through timely adjustments to the production process and mold maintenance plan, we ensure that the texture of each tire leaving the factory meets the strict design standards and quality requirements.

In addition, the white light interference 3D profiler can also be combined with other measurement equipment and techniques, such as with hardness measurement equipment to study the relationship between the hardness distribution in the tire texture area and the structure of the texture, and with finite element analysis software to simulate the force and wear of the tire texture under different road conditions.

The white light interference 3D profiler provides an advanced, efficient and accurate solution for high-precision measurement of tire texture, which strongly promotes the progress of the tire industry in all aspects of design, production and inspection, and lays a solid foundation for manufacturing safer, high-performance and durable tires.
