Quality is the foundation upon which we build our global presence. We have established a comprehensive and rigorous quality control system that spans from the selection of raw materials to the final product’s departure from the factory. We carefully select high-quality spring steel, stainless steel, copper alloys, and other raw materials. We are equipped with state-of-the-art intelligent coil spring machines, precision heat treatment production lines, and fatigue testing equipment. This enables high precision, automation, and scalability in the production of springs. The factory holds ISO 9001 international quality certification and TS 16949 automotive industry-specific certification. All products comply with international environmental standards such as ROHS and REACH. Each spring undergoes comprehensive testing in terms of salt spray, tensile strength, torsion, and precision, ensuring its stability and reliability under various overseas conditions and its suitability for diverse global market demands.
