Recently, Guizhou Tire, the leading tire manufacturer in China, announced that its self-developed “device for reducing the incidence of sidewall suspension turn-up folds” has been officially authorized for a utility model patent. The patent proposes a new solution to the common problem of sidewall turn-up wrinkles during the tire molding process. It is expected to further improve the molding qualification rate and appearance quality of tire products, and reduce the loss rate of defective products at the production end.
According to patent disclosure information, this device belongs to the technical field of tire building equipment. The core structure includes two sets of symmetrically arranged clamping assemblies. By setting a first ball bearing on the central axis of the mounting bracket to match the arm rollers, and at the same time, multiple sets of second ball bearings are installed on the arm axes on both sides, which greatly reduces the
It eliminates the rigid friction and pulling force experienced by the sidewall material during the turn-up process, and solves the structural root cause of the industry pain point of traditional arm arm devices that easily cause sidewall suspension turn-up and discount. It can be directly applied to the technical upgrade of existing all-steel radial tires, engineering tires, agricultural tires and other production lines, with low transformation costs and strong adaptability.
As a long-established backbone enterprise in the domestic tire industry, Guizhou Tire entered the capital market in 1996 and has been focusing on tire research and development, production and sales for many years. Its products cover multiple application scenarios such as passenger cars, commercial vehicles, engineering equipment, rail transit, etc. Its technical strength and market competitiveness have firmly ranked first in the industry.
The latest operating data shows that in 2025, Guizhou Tire achieved operating income of 10.946 billion yuan, ranking 6th among 22 comparable companies in the same industry, higher than the industry average revenue level; it achieved a net profit of 623 million yuan, ranking 8th in the industry, significantly higher than the industry median level.
Among them, the core tire sales business revenue reached 10.87 billion yuan, accounting for 99.3% of the total revenue. The main business advantages are very prominent.
The implementation of this new patent is an epitome of Guizhou Tire’s continuous increase in technology research and development in recent years.
Public data shows that since 2025 alone, Guizhou Tire has had more than 50 patents that have entered the disclosure or authorization stage, covering a wide range of areas: not only product patents for tire material, structure, and performance optimization, but also production-end technology patents such as production process upgrades, intelligent quality control systems, energy-saving and consumption-reducing transformations, and production safety protection. They also include digital operation-related patents such as Internet of Things factory management and control, production scheduling systems, and laboratory measurement management, which comprehensively cover the entire chain of tire production and manufacturing.
The intensive technology patent layout not only provides support for Guizhou Tire to improve product quality and reduce production costs, but also lays a solid technical foundation for the company to subsequently expand the global market and enhance the international competitiveness of China’s tire products.
