Mechanical springs are mechanisms that exert force by compressing, rotating extending, pulling or sliding.  They include a wide a range of wire forms including extension springs, torsion springs, rectangular springs, compression springs and more. Wire springs are produced in a range of configurations, thicknesses, and sizes and are used in everything from small household tools and appliances to heavy machinery.

Wire springs are typically made using two methods: coiled wire or metal stamping.  To create coiled springs, stock wire is fed into a machine or place on a lathe that forces the wire into the desired shape. Additional coatings or finishes may also be applied for aesthetics or to create a protective coating. Another method is metal stamping, which is a process where dies and hydraulic presses are used to cast, punch and shape high volumes of molded forms from flat sheets of metal. Custom metal stampings are used in household appliances, electronics, automotive parts, HVAC components, and heavy machinery.

Or, if none of our off the shelf options are right for your project, we also offer custom springs made to your specifications.

Compression Springs

Compression springs are wire forms that provide the highest amount of potential energy when they are compressed and release energy as they return to their natural position. They are typically manufactured in helical spring, tapered spring or rectangular spring shapes and vary in size and thickness.

  • Helical springs, also known as coils springs, are made from round wire and have a standard coiled shape. They are highly versatile and used for a wide range of applications.
  • Tapered springs have a conical shape with a wide base and a narrow top. They collapse into themselves when compressed and provide more stability than other types of mechanical springs.
  • Rectangular springs have an oval shape and are made from rectangular wire. They are typically used in applications where space is limited and can store more energy than springs made from round wire. 
Custom compression springs are the most common type of wire spring and are used by industries including manufacturing, aerospace, construction, agriculture, automotive, medical and transportation. Compression spring wire forms are an economical choice that is used in a range of products including:  
  • Ballpoint pens
  • Door locks
  • Automotive components
  • Appliances
  • Medical devices
  • Mechanical equipment
  • And more

Extension Springs

Extension springs, also known as tension springs, are cylindrical wire forms with a tighter coil than compression springs and are sometimes manufactured with loop, eye or hook at both ends for mounting. They produce the highest amount of potential energy when extended and then release the energy when returned to a compressed position. Custom extension springs can store and absorb energy and are used for applications where pulling force is required.

Some of the most common applications for custom extension springs include:

  • Toys
  • Medical devices
  • Hand tools
  • Trampolines
  • Automotive components
  • Washing machines
  • Garage doors
  • Agricultural equipment
  • And more

Torsion Springs

Torsion springs are helical wire forms that exert force in the opposite direction when they are twisted. They produce both torsional and rotational forces and can be wound either clockwise or counter-clockwise.  When a torsion spring is twisted, it stores mechanical energy that is then released when the wire spring returns to its natural position.

Custom torsion springs are used for a wide range of home, industrial and manufacturing applications including: 

  • Mouse traps
  • Automotive parts
  • Door hinges
  • Clipboards
  • Retractable seating
  • Clocks
  • Medical equipment

Metal Stampings

Metal stampings are flat springs and fasteners created from thin sheets of metal. Because dies are used, they can be bent and formed into a wide range of shapes and sizes and are suitable for high volume production runs.

Common applications for custom metal stampings include:
  • Appliances
  • Automotive parts
  • Lighting
  • Electronics
  • Medical equipment
