2. Coiling Unit This is the heart of the spring making machine. It is responsible for shaping the wire into coils, which form the spring’s body. Advanced machines use CNC (Computer Numerical Control) technology to accurately control the dimensions of these coils, ensuring consistency across all produced springs.
2. Formation of the Pipe Once the paper is prepared, it is wrapped around a mold or core. The wrapping is done in a controlled manner to ensure uniform thickness and adhesion. Some machines employ heat and pressure to bond the layers of paper together, enhancing the integrity and strength of the pipe.
