We are specializes in precision spring engineering and custom spring solutions, offering a comprehensive range of high-performance springs including precision compression springs, extension springs, torsion springs, and special-shaped springs. Our capabilities span advanced material selection (music wire/stainless steel/titanium alloy), CNC coiling with ±0.01mm dimensional precision, and comprehensive testing systems integrating FEA simulation and 500,000-cycle fatigue validation.
LiHong HardWare, as a global precision spring solutions expert, specializes in the R&D and manufacturing of compression springs, extension springs, torsion springs, and custom-shaped springs. We provide end-to-end services spanning material selection (music wire/stainless steel/titanium alloy), parameter customization (wire diameter 0.08-15mm, adjustable stroke 0.1-3mm), and surface treatment (electroplating/passivation/multi-layer protection). Our spring products play critical roles in consumer electronics (smartphone linear motor buffering), new energy vehicles (battery pack pressure equalization), medical devices (precision testing instrument shock absorption), and semiconductor testing (high-temperature environment resistance). Notably, in 5G base station cooling systems, our customized disc springs achieve ±0.02mm positioning accuracy and withstand -40°C to 150°C extreme environments, ensuring operational stability.
