There are many types of spring, such as twisted spring, planar vortex spring, vortex spring, Lashen spring, which is closely related to our daily life. The following is a simple and detailed introduction to the production and manufacturing of spring.

Spring production and manufacturing methods include cold winding method and hot rolled coil method. Hardware spring wire diameter is less than 8 mm with cold winding method, more than 8 mm with hot rolled coil method.

Generally speaking, manufacturing materials should have high ductility limit, fatigue strength, fracture toughness and excellent heat treatment process characteristics, etc. Common materials include carbon hardware spring steel, aluminum alloy hardware spring steel, stainless steel hardware spring steel and its alloy copper, nickel base alloy and vulcanized rubber.

Some hardware springs need to be made after the air brake or shot peening treatment, can improve its bearing capacity. It is also a kind of elastic element widely used in the mechanical equipment and electronic industry. When supported, it should cause great elastic deformation, and convert mechanical work or mechanical energy into deformation energy. After unloading, the deformation of the hardware spring recedes and responds to the original appearance, and the deformation energy is converted into mechanical work or mechanical energy.
