Those who work in certain industries need to be aware of the materials that make up their machinery and equipment. This ensures safety and quality and it can also help you plan your budget more efficiently. If you work with machinery you need to understand the difference between extension springs and compression springs. This way you will be able to determine which option is best for you and when the manufacturer of your equipment is discussing certain items with you, you can figure out quickly what they are talking about. While you may not need to know everything about these items, it is important to have a general understanding of how the two options work.

The extension variety is attached at both ends to the other components. As the two pieces of the item move apart, the spring pulls them back together. This type absorbs and stores energy and it creates a resistant pulling force. The tightness of the coil is determined by the original tension. The tension can be manipulated to match load requirements and weight of the coil-connected components. They are often made with eyes and hooks that attach to the component pieces. There are sometimes extended twist loops, threaded inserts, center loops, hooks, or tear-dropped shape ends which vary in distance from the body of the coil. Custom-designed models can be shaped to have different distances, depending on the needs of the equipment. The draw-bar variety of extensions applies the load to the ends of the loops which are passed through the center and hook around the opposite end. This type works great in situations where it may be overloaded with weight because they have a built-in stopping point.

Extensions are used in the interiors and exteriors of automobiles. They are also an important part of garage door assemblies, as well as trampolines, vise-grip pliers, carburetors, farm machinery, washing devices and a variety of different toys. They are available in a large variety of sizes ranging from very small, which are often found in medical devices to ones large enough to be used in off-road machinery brakes. The draw-bar style is often found in patio furniture.

The compression variety is an open-coil style designed to oppose compression along the axis of the wind. They are the most common variety. They are often placed over a rod or fitted in a hole. When you put the load weight on it, it makes it shorter and it pushes back against the load, trying to get to its original form. They offer resistance and are considered one of the most efficient energy storage devices you can use.

The most common of these types is the straight metal coil. This kind has a diameter that is the same as the entire length of the entire component. In addition to the straight metal coil variety, there are also conical and barrel types which are convex and an hourglass shape which is concave. Regardless of which type you need for your particular job, be sure you choose a manufacturer that is experienced and makes a quality product.
