Mainland China has taken a significant step in the global tire manufacturing industry by beginning to purchase vulcanizing presses from domestic manufacturers. On October 28, a four-member team from German Continental Tire Co. visited the Guilin Rubber Machinery Plant and officially accepted a newly developed 62-inch hydraulic vulcanizing machine tailored for the mainland market. The team gave a thumbs-up, saying, "OK, China's vulcanizing machine." This milestone marks a major achievement for China Rubber Machinery, as it has now successfully supplied equipment to the world’s top ten tire manufacturers, placing Chinese vulcanizers among the global leaders in technology and quality.
Vulcanization is the final and critical step in tire production, and the vulcanizer is one of the most essential machines in radial tire manufacturing. The quality of the tire is directly influenced by this process, which is why leading tire companies are extremely selective when purchasing such equipment. Before Bridgestone began ordering Chinese vulcanizers in bulk, they conducted multiple small-scale trials, gradually increasing the size of their orders. From just one or a few units initially, they now place contracts for over 100 units at a time. Similarly, Michelin requires suppliers to be integrated into its procurement system, and after a comprehensive global evaluation, Guilin Rubber Machinery Plant was recognized as a qualified supplier. Autocontrol AG also serves as a long-term provider of mechanical vulcanizers.
The mainland became the last of the world’s top ten tire companies to include Chinese rubber machinery in its procurement system. It places a strong emphasis on tire equipment and, when evaluating global suppliers, focuses not only on product quality but also on the supplier’s overall quality management system and production capacity. In the first half of this year, the mainland conducted a thorough inspection of the Guilin Rubber Machinery Plant and rated it as an A-grade supplier, paving the way for its vulcanizing machines to enter the company’s procurement system. These developments confirm that in recent years, China’s tire vulcanizers have made a significant leap in precision, reliability, and stability.
Today, all of the world’s top ten tire manufacturers use vulcanizing presses produced in China. More than 30 out of the 75 largest tire companies worldwide rely on Chinese-made vulcanizing machines. This success is largely due to the national implementation of the “machine-based cans†project, the localization of key radial tire equipment, and the “one-stop†project. Additionally, increased trade exchanges between the Chinese rubber industry and global tire giants have played a crucial role.
Guilin Rubber Machinery Factory and Huazhou Rubber Autoclave have both passed CE certification, enabling them to export their products without technical barriers. Guilin has also established a global service network in the U.S., Japan, and other regions, ensuring timely support and spare parts supply—further building trust with multinational tire companies. Moreover, through strong cooperation, Kobe Co., Ltd. of Japan has placed all its vulcanizing machines with Yiyang Rubber and Plastic Machinery Group, leading to large-scale exports. These achievements reflect the growing global recognition of China’s capabilities in tire manufacturing equipment.
