Big spring is also known as hot coil spring, the production process adopts hot coil technology. The parts made of elastic materials are deformed under the action of external forces, and then recover to their original state after removing the external forces. Usually made of spring steel. Big spring general wire diameter is very big, easy to twist the shape after heating, small elasticity, need quenching after tempering treatment after molding. Large springs can produce large elastic deformation under the action of load and are widely used in all kinds of machinery.
