Springs are fundamental hardware components that utilize elastic deformation to achieve energy storage, restoration, buffering, shock absorption, and clamping functions. They are formed through precision stamping, bending, and heat treatment processes and are widely used in sheet metal structures and assembly equipment in fields such as electrical cabinets, new energy equipment, construction machinery, and rail transit.
We support full-dimensional non-standard customization, allowing adjustment of wire diameter, number of turns, free length, and elastic parameters according to customer equipment operating conditions. Springs are a core product category in our hardware stamping export business. Non-standard customization is supported.
