As a key link in the modern tire manufacturing process, tire texturing technology plays an irreplaceable role in tire quality control and performance optimization.
With the rapid development of new energy vehicles and consumers’ increasing requirements for quietness and safety performance, tire texturing technology is undergoing a transformation from traditional processes to advanced laser technology.
Tire texturing refers to the micron-scale rough structure formed on the tire surface (especially the inner wall), which mainly includes two forms: lanugo hair and artificial texturing.
The presence of lanugo hair has a clear process indication significance, indicating that the mold exhaust system is working properly during the vulcanization and molding process of the tire and can ensure the integrity of the tire structure.
Tire texturing technology has two core significances in tire manufacturing: quality assurance and performance enhancement.
In terms of quality assurance, lanugo hair can verify the reliability of the mold exhaust system and easily determine the quality and aging of tire rubber.
In terms of performance enhancement, it can improve the bonding performance of sound-absorbing cotton, improve surface energy and wettability, and reduce cavity noise.
Laser tire texturing is essentially the process of interaction between a high-energy laser beam and the tire surface material.
Its energy conversion mechanism includes energy absorption and conversion, such as heat conduction, photochemistry and plasma effect; the surface morphology generation mechanism mainly includes melting-solidification mechanism and vaporization-deposition mechanism. By accurately controlling laser parameters, precise control of surface roughness can be achieved.
Laser tire texturing has many key technical features.
Laser parameters such as power, pulse width, frequency, etc. have an impact on the texturing effect; it can achieve precise control of the surface topography, including roughness uniformity, texture type diversity and controllable microstructure size; compared with traditional texturing methods, it has the advantages of high precision and consistency, environmental protection characteristics, high processing efficiency, wide adaptability, and high equipment integration.
In actual production applications, the typical application process of laser tire texturing includes loading and positioning, laser processing, dust removal and unloading stages.
Modern laser tire texturing equipment adopts a modular design, including laser light source system, processing execution system and auxiliary system.
Laser tire texturing technology is widely used in silent tire manufacturing and can be used for surface treatment of silencer cotton bonding, sealant coating and surface contaminant removal.
Traditional tire texturing methods mainly include chemical corrosion, mechanical grinding and sandblasting, etc., but they all have limitations, such as serious environmental pollution, difficult process control, and risk of material damage.
Compared with traditional methods, laser tire texturing has obvious advantages in terms of initial investment cost, operating cost, processing efficiency, surface quality, environmental protection, applicability and degree of automation.
From a long-term operation perspective, laser tire texturing has better economic benefits, reducing overall production costs and improving product quality and customer satisfaction.
Laser tire texturing technology has been widely used in the field of tire manufacturing. In the future, it is developing in the direction of process standardization and standardization, intelligent and digital upgrading, multi-process integration innovation, green manufacturing and sustainable development.
Its applicable scenarios include high-end silent tire manufacturing, high-precision requirements scenarios, production environments with strict environmental protection requirements, large-scale automated production lines and high value-added tire products, etc.; in the low-end tire retreading market, small batch customized production, special rubber formula processing and areas with loose environmental standards, the traditional process still has application value.
In summary, tire texturing has dual significance. Laser tire texturing technology has significant advantages, and the selection of tire texturing process needs to be comprehensively considered.
Tire manufacturing companies should formulate differentiated process strategies, strengthen research on the correlation between process parameters and quality testing, promote the construction of industry standards and certification systems, and pay attention to the integration and innovation of laser technology and other processes.
In the future, laser tire texturing technology will further develop in aspects such as intelligence, multi-axis linkage, establishment of process parameter database and adaptive control system, and integration of green manufacturing and circular economy.
