Spring Testing Machine

Digital & Computerized Spring Testing Machine

Stark Embsys manufactures high-precision Digital & Computerized Spring Testing Machines engineered for testing compression springs, tension springs, disc springs, and leaf springs. Equipped with load cells, digital displacement scales, and motorized/manual loading mechanisms, our spring testers determine spring rate (stiffness), free length, loaded length, and solid height.

Essential for automotive spring manufacturers, railway suspension testing, valve spring quality control, and precision instrument spring inspection across India.
