It is a combined finished part assembled by matching springs with CNC parts, stamping pieces and plastic components.
Spring assembly is a finished combination product integrating various springs with CNC machined parts, stamping components, plastic fittings and fasteners via assembly processes. It includes tension spring assemblies, compression spring assemblies, torsion spring assemblies and formed wire spring assemblies as per different spring types. Raw materials cover stainless steel, carbon steel, aluminum alloy and engineering plastic, with optional surface treatments like electroplating, passivation and anodization for anti-rust and wear-resistant performance. Strict assembly inspection ensures stable elastic performance and matching precision of each component.Instead of supplying single springs separately, integrated spring assemblies help clients save secondary processing and assembly costs. They are widely applied in medical devices, automobile parts, household appliances, electronic products and automation equipment, with customized structure and specifications available based on customer drawings and application requirements.
Spring assemblies are custom-engineered products comprising multiple components. Typically featuring a central spring, the ends can be designed—using hooks, machined threaded parts, or welded fittings—to suit specific assembly requirements. Yisen manufactures these assemblies from a variety of materials, including stainless steel, aluminum, copper, and iron. By integrating fasteners such as screws, nuts, and washers, we enable rapid installation and expanded functionality, overcoming the traditional limitations of spring applications. With rapid response and flexible manufacturing as our core strengths, we help customers shorten R&D cycles and optimize product performance.

Spring assemblies are core connecting components that ensure the stable operation of new energy vehicles' three-electric systems. They are widely used in battery pack locking mechanisms, motor brush holders, electronic throttle bodies, and charging interfaces. Precisely assembled spring assemblies can provide constant contact pressure and cushioning force throughout the vehicle's entire service life, effectively resisting vibration and impact during driving, ensuring the reliability and safety of high-voltage circuit connections, and improving the vehicle's overall energy conversion efficiency.
In high-precision semiconductor wafer processing equipment, spring assembly components perform critical functions of precision positioning, elastic clamping, and shock absorption. From wafer transfer mechanisms in lithography machines and probe card testing devices to vacuum sealing systems in ion implanters, custom-designed spring assemblies enable micron-level precise control, maintain long-term stable performance in ultra-clean dust-free environments, and ensure the yield and accuracy of chip manufacturing.
Medical devices impose extremely stringent requirements on the safety, stability, and biocompatibility of spring components. Precisely assembled spring assemblies are widely used in syringe push rods, infusion pump valves, ventilator pressure regulating mechanisms, and detector arrays in CT scanners. They provide precisely controllable elastic force output, maintain consistent performance during frequent reciprocating motions, and offer reliable technical support for clinical diagnosis and treatment.
High-performance spring components are indispensable for the joint drives, end effectors, and safety protection systems of industrial robots. Integrated spring assembly modules can absorb shock and vibration generated by robots during high-speed movement, enable flexible grasping and precise positioning, and provide reliable cushioning protection during emergency braking. This significantly improves the operational stability and service life of robots, making them widely applicable to automated production lines in automotive manufacturing, electronics assembly, and other industries.
