YH auto R&D Research results
Development of Heterogeneous Single-Sided Coil Spring (2023)
Through the development of a deformed single-sided coil spring (2023), we have developed a spring material and manufacturing technology that can improve durability by 20% compared to the existing circular cross-section.
Development of leaf spring using glass fiber composite (2024)
Through the development of leaf springs using glass fiber composites (2024) We have secured next-generation spring technology that can achieve 50% weight reduction compared to existing steel.
