Shandong Hongsheng Rubber Technology Co., Ltd., established in 2014, boasts assets of 3.8 billion yuan and over 2,000 employees. With an annual production capacity of 24 million high-performance semi-steel radial tires, it is recognized as a national-level "Little Giant" enterprise specializing in precision and innovation, a national-level green factory, and an advanced smart factory in Shandong Province.

In the workshop, the intelligent molding machine operates at high speed, shaping rubber raw materials into the tire embryo of "memory rubber" high-end tires at a second-level pace. The highlight of this product lies in its formula and structure: it uses modified solution-polymerized styrene-butadiene rubber, combined with low-temperature mixing technology, to strike a balance between wear resistance, low rolling resistance, and strong grip; the tire body adopts a "6+2" reinforced design, equipped with double-layer high modulus low shrinkage cord and crown composite blended reinforced cord, which can quickly recover its original shape after being deformed under stress.

After the embryos are off the production line, they are automatically scanned and weighed, and then enter a 12-meter-high intelligent three-dimensional warehouse with nearly 7,000 storage locations via a conveyor line. The entire process is automated by stackers and MES systems, resulting in an increase of over 60% in inventory management efficiency.

The self-repairing silent tire has secured the title of the ninth batch of Shandong Provincial Manufacturing Industry Single Champion, with a market share of 32% in the province. "This high-end tire made of memory rubber fully covers all domestic new energy vehicle usage scenarios, and our order book is very full. The production plan has been scheduled until the end of June," said Song Fangzhao, the head of the enterprise's production management department.
