Hot Metal Rod Shaping into Big Spring - Video

Once the metal reaches the required heat level, it is fed into a specialized spring-forming machine. This machine applies controlled force and rotation to coil the hot rod into a precise spiral shape, forming a strong and uniform spring structure.
During the shaping process, careful control of temperature, speed, and tension is essential to ensure the spring maintains its strength, elasticity, and perfect alignment. After coiling, the spring is gradually cooled to lock in its final shape and improve durability.
