It can be easy to confuse compression springs and die springs as they function in an extremely similar way. However, in actual fact the two springs differ in many ways, but just what are the factors that set them apart?
As manufacturers of compression springs, we like to think we are experts in this type of spring. The helical compression spring is perhaps one of the most common spring types and has a wide variety of uses. They are used in many objects we use in our day to day activities, from business to home life. Due to their versatility, compression springs are used in everything from valves to switches and even indoor mechanisms.
Generally, these springs are made up of helically formed coils. They are used to push back on an applied force or load which makes it return to its original position when released. In more simple terms, they are designed to resist compressive forces. When the coil shortens in length, it stores mechanical energy whilst under stress.
The unique design of this spring means that their compressed and helix shape allows them to resist compressive forces. In turn, this means that they can be manufactured, as mentioned above, into anything from cylindrical to conical and even into a concave shape, with variable or constant pitch and a choice of ground or unground ends.
The die spring is often referred to as a ‘high force compression spring’, which is why it may be confused with the compression spring. In a sense, die springs are a stronger, more concentrated, hybrid version of the compression spring, but are made with rectangular wire instead of the otherwise circular counterparts.
While a compression spring has strength behind it, a die spring can take a much higher load when required to do so. In fact, a die spring can withstand approximately 30% more pressure than a standard compression spring, as well as being able to spring into action under temperatures up to 475 degrees Celsius.
The extra resistance which die springs are known for gives them greater strength and a decrease in load loss compared to compression springs, which is why it is they are used for things as clutches and brakes in vehicles and for heavy machinery applications.
Die springs are the spring of choice when a high force is required or when there are limited installation dimensions or a confined space. Die springs come in 4-5 distinct types of force class to choose from, ranging from 1 to 5. To achieve the best outcome from your choice of die spring you should always choose the most appropriate force class.
So, What’s the Main Differences?
Just because die springs are essentially an enhanced version of the compression spring, that doesn’t necessarily mean they are better in general. If you need a spring for heavy machinery, brake or clutch then a die spring will suffice; however, not all applications need die springs.
No matter what spring you need; compression or die, here at European Springs Ireland, we make sure we put all our efforts, time and accuracy in creating springs of the highest quality for your projects.
Alongside our up-to-date technology, our methods and attitude make a recipe for success, in both our business and in our products.
