Types of Coil Spring :-
- Compression types of Coil Spring – This type of Spring is designed to compress when a load is applied and return to its original shape when the load is removed.
- Extension types of Coil Spring – This type of Spring is tightly coiled coils that produce tension when a load or force is applied to their ends, forcing them to lengthen. They are also referred to as Extension or Expansion Spring.
- Torsion types of Coil Spring type – This type of Spring is to operate with a twisting or rotational force. They store and release angular energy or apply torque.
