Leading Coil Spring Manufacturers

A coil spring is a spiral-shaped mechanical device. Springs can be close-wound or open-wound. Coil springs serve as mechanical energy reservoirs made of metal or elastic materials. Coiled springs are common in everyday products, like farm machinery, toys, or trampolines.Read More…

Coil Springs Coil springs are coiled metal or plastic cords used to store or absorb mechanical energy. Coil springs are among the most widely recognizable spring configurations, and their design is one of the simplest among all spring configurations.

Coil Spring

How Springs Work

Coil springs store energy to release it. Springs can also absorb impact or apply force between surfaces. A spring may be stretched past its breaking point if excessive force is applied, irreversibly distorting it.

Common Applications for Coil Springs

There are numerous designs and uses for the coil spring. In 1857, a steel coil spring for an armchair was invented. Coil springs are used in a wide range of daily items today, such as:

  • Clocks
  • Automobiles
  • Retractable pens
  • Door handles
  • Toasters
  • Gates
  • Toys (e.g., the Slinky)
  • Garage doors

Types Of Coil Springs

Cylindrical Springs: Compression and Extension

A cylindrical spring is designed to interact with heavy weights. There are cylindrical compression and cylindrical extension springs. Compression springs will compress when interacting with heavy objects. Normally, compression springs are set up underneath a heavier weight. Cylindrical extension springs are built with curved hooks at either end and come already tightly wound. They are hooked onto heavy objects and are pulled open.

Conical Springs and Mini Block Springs

A conical spring has a larger diameter on one end. They are also called ‘tapered springs’. A mini-block spring is similar, with small diameters on either end and a larger diameter in the middle. Mini-block springs are designed for the coils to layer inside each other when compressed. Mini-block springs are ideal when the spring needs to fit into a flat space in its compressed state.

Advantages of Coil Springs

Flexibility in Design: It is possible to calculate how springs will perform based on their size and material, which allows for an accurate design process. Changing the size, shape, thickness, and material of coil springs will create calculated outcomes that manufacturers can customize for specific applications.

Long-lasting Design: Coil springs are designed to be durable as they stretch. Manufacturers can use rust-resistant materials that withstand extreme temperatures to design coils. Most industrial springs are designed to have a long life with very little upkeep or lubrication required.

Choosing the Correct Coil Spring Company

To make sure you have the most productive outcome when purchasing coil springs from a coil spring company, it is important to compare at least 4 manufacturers using our list of coil spring manufacturers. Each coil spring company has a business profile page that highlights their areas of experience and capabilities and a contact form to directly communicate with the company for more information or request a quote. Review each coil spring company website using our patented website previewer to get an idea of what each business specializes in, and then use our simple RFQ form to contact multiple coil spring companies with the same quote.

Coil Springs

Coil Springs

A coil spring is an elastic element made of metal or heavy plastic in the form of curls or ringlets of round wire or cord that is wrapped around a cylinder. The winding of a coil spring can be loose or tight in a helical shape depending on the application for which it is made...

Compression Springs

Compression Springs

Coil springs called compression springs can store mechanical energy when they are compressed. These open-coiled, helical springs provide resistance to compressive loading. When these springs are...

Extension Springs

Extension Springs

Extension springs are helical wound springs that are so closely coiled together to create initial tension in the coils. This initial tension creates resistance against the force applied to its ends for extension. The initial tension helps determine how closely and...

Metal Springs

Metal Springs

Springs are a flexible machine element that store mechanical energy when subjected to tensile, compressive, bending, or torsional forces. When the spring is deflected, it stores energy and at the same time exerts an opposing force...

Torsion Springs

Torsion Springs

A torsion spring is a mechanical device that stores and releases rotational energy. Each end of the torsion spring is connected to a mechanical component. As the spring is rotated around its axis on one end, the winding of the spring is tightened and stores potential energy...

Wire Forming

Wire Forming

Wire forming is a method for applying force to change the contour of wire by bending, swaging, piercing, chamfering, shearing, or other techniques. The various techniques for wire forming can produce any type of shape, form, or configuration...
