Guilin Rubber Machinery’s first self-developed 77-inch new-type dual-mode hydraulic vulcanizer for engineering tires was packaged and delivered to its domestic customer on May 18.

Compared to the traditional vulcanizer for engineering tires, the new vulcanizer has dual-mode design and compact main structure, saving over 20% of space. The lifting of the crossbeam adopts double guide posts, which makes the lifting more stable and reliable. The left and right modes are completely independent, which can vulcanize tires with different specifications in both single mold and double modes. The double-pump hydraulic control system is adopted to achieve its energy-saving, environment-friendly, efficient and low-noise features. The auxiliary vulcanization time is shortened by nearly 25% and the production efficiency is enhanced by a large margin.

Lei Ji, deputy chief engineer of Guilin Rubber Machinery and director of the Technology Center, said, “The successful R&D of this new product has expanded our company’s product line of 70-80 inch dual-mode hydraulic vulcanizers, laid a solid foundation for the R&D of other specifications, and provided strong support for our customers to efficiently produce high-quality engineering tire products.”

In recent years, Guilin Rubber Machinery has continuously increased its investment in R&D and innovation. In 2019, the 212-inch hydraulic vulcanizer was developed to assist Aeolus Tyre in producing its current largest engineering radial tire.
