Birmingham Springs Products and ServicesThe most common way to classify springs is by how load is applied to them. You’re probably familiar with the following:
Designed to operate with a compressive load and found in shock absorbers, spring mattresses, mechanical pencils, and retractable pens.
Designed to operate with torque (twisting force); powers every clothespin and mouse trap.
Lightweight coil springs are made by forming metal wires on an CNC coiling machine. The multi-axis CNC control allows you to create variable pitches.
Springs that come off the coiling machines do not have springy properties. They need to be heated to a high temperature (typically 500 degrees Fahrenheit or more) to relieve stress, then quenched to create shape memory.
Machined springs and die springs are used for heavy duty applications with high strength and precision requirements. As the name suggests, machined springs are made on CNC lathes and mills.
Designed to operate with a tensile load. The spring providing a contracting force. These are also found in luggage scales and garage door mechanisms.
Springs can also be classified by how they’re made.
Flat springs come in all sorts of sizes and shapes: Spring washers, PCB spring contacts, and retainer clips are all examples of flat springs. Essentially sheet metal parts, they can be made by stamping. However, there are coiled flat springs as well, such as clock springs and volute springs. They also need be heat treated for shape memory.
Plastic or composite springs are commonly found in corrosive environments, such as food production, medical, and marine applications.
