Haozong was founded in July 2009. Starting from a small office at the initial stage, it has gradually developed into a diversified enterprise with standardized workshops. In 2020, the company built its own factory, equipped with CNC machining, experimental and inspection equipment, improved production processes and drawings, and laid a solid foundation for high-quality production. After years of honest operation, the company has established close cooperative relationships with well-known global manufacturers and a large number of users, and has become an important channel for introducing advanced technologies and products in China's manufacturing industry. During its development, it has successively established business entities such as Tainida Shock Absorption and Kunshan Haozong. Currently, Kunshan Haozong Transmission Technology Co., Ltd. operates the core brand. The business scope has expanded from initial brand agency to independent R&D and production, with core products covering five major series: precision diaphragm couplings, heavy-duty diaphragm couplings, plum blossom couplings, high-elasticity couplings and ETP hydraulic expansion sleeves. The products are widely used in various fields such as agricultural machinery, construction machinery, aerospace, electronic equipment, machine tools, metallurgy, petrochemical industry, fire protection and medical treatment. Haozong has always adhered to the business philosophy of "Sincere Mutual Trust, Customer Satisfaction, Quick Response and Continuous Innovation", and is committed to building an advanced enterprise in the transmission industry and achieving win-win results with customers.
