With the booming development of new energy vehicles in China, the air spring industry is on the rise. EVEN Co., Ltd. (EVEN), founded in September 2022 in Qingdao, is built upon the National Engineering Research Center for Rubber and Tire (Guoxiang Center).

Guoxiang Center is the only and highest-level technology innovation and industrial ecosystem platform in China's rubber and tire industry. It was jointly built in 2009 by Qingdao University of Science and Technology, Mesnac Co., Ltd., and Sailun Group Co., Ltd., which is an engineering technology research center approved as a "Pilot Unit for Management Model Innovation" by the Ministry of Science and Technology of China. Guoxiang Center pioneered the use of continuous liquid phase mixing (EVEC) technology to produce "liquid gold" material, overcoming the "magic triangle" problem that has plagued the tire industry for over a century.

In order to solve the problem of domestic automobile parts relying on imports, on November 29, 2019, Guoxiang Center and FAW Group jointly established the "Automotive Rubber Products Alliance Innovation Lab", aiming to make breakthroughs in the research and development of high-performance tires, all-weather tires, air spring bellows, and other rubber parts. With the cooperation of the laboratory, relying on its unique advantages of industry-university-research cooperation and the well-supported industrial chain, Guoxiang Center was the first to successfully apply the internationally pioneered "liquid gold" technology to air spring bellows, endowing them with excellent tensile fatigue and flex cracking performance. The durability test of the product is more than twice that of competitors, reaching the international leading level. EVEN achieved the transition from project initiation to the launch of its first industrial-grade product in just 8 months, and passed the strict OEM tests on the first attempt, setting a new benchmark in the industry.

With the mass production of bellows, EVEN came into being in 2022. By mastering the technologies of bellow formula development, structural design, and manufacturing, EVEN is capable of custom development and collaborative design of bellows based on customer needs, with product performance and reliability reaching world-class standards, and has achieved full lifecycle traceability of products through information technology systems. EVEN has broken the international monopoly on passenger car bellows, becoming a leading enterprise in China's air spring bellows industry. In addition to air spring bellows, EVEN has also developed high-performance products of skeleton oil seals and bushings, all of which have passed OEM testing.

Since its establishment, EVEN has provided more than 3 million bellows to vehicle manufacturers, which are applied to multiple popular models in the market. It has become a professional brand trusted by the industry, and ranks first in the domestic market share of passenger car bellows. At present, EVEN has an annual production capacity of 3 million passenger car air spring bellows and 100,000 commercial vehicle air spring bellows. The new factory is planned to start construction in 2025, with a planned annual production capacity of 10 million passenger car air spring bellows, 4 million commercial vehicle bellows, 1 million seals, and 1 million bushings to meet the needs of domestic and foreign markets.

EVEN attaches great importance to technological innovation. The independently developed automatic winding process bellow production line fills a domestic gap and has established itself as a model for self-developed high-level technology. The enterprise regards quality as its life and has independently developed IT and digital systems including MES, WMS, and U9C, enabling full lifecycle traceability from raw materials to finished products. At the same time, the enterprise focuses on intelligent manufacturing, and the independently designed and developed production lines of automatic cutting, inspection, and packaging have all been successfully applied.

Looking ahead, EVEN will stay market-driven, backed by fundamental research. Leveraging its industrial chain strengths and increasing R&D investment, the company will deepen its presence in high-end rubber products and continuously deliver competitive, high-quality products that meet market needs.
