Die springs

Contents

Introduction

Die springs play an integral role within the manufacturing and engineering industries. Similar to compression springs, die springs are manufactured and built to take a higher load than other springs, making them a valuable tool for a variety of projects.

For a die spring to work without hindrance, there has to be room for it to work. This means the starting point is not the physical dimensions of the die spring, but the installation dimensions.

What are die springs?

Also referred to as ‘high compression springs’, die springs are designed to maintain and withstand great levels of applied stress. These types of springs are made with rectangular wire instead of circular, unlike their ‘compression’ counterparts.

This type of high force compression spring can handle 30% more stress than a standard compression spring. This can be beneficial in extreme and stressful environments, such as handling temperatures rising to 475 degrees.

Properties of die springs

Die springs have a number of unique qualities, the first being the material they are made from. The use of rectangular and square wire is the prime element that gives the die spring its unique property, and it is this larger mass which provides the spring with a greater force.

Die springs are an extremely reliable and consistent spring. They can be manufactured to different strengths, which is shown through the use of different colour codes.

Common uses of die springs

Due to their strength, die springs are used for a wide range of applications within various industries, including:

  • Clutches and brakes in the automotive industry.
  • Transportation industry.
  • Agricultural industry.

The difference between compression and die springs

Springs may look similar, but the different variations of springs all have different characteristics, designed for different purposes. Compression and die springs are two which are similar, but with several differences.

Compression springs function by resisting compressive force. When stress and pressure is applied, their length shortens, allowing them to store energy whilst compressed.

Compression springs are used in a wide range of applications, including:

  • Ballpoint pens
  • Door locks
  • Automotive systems
  • Medical devices
  • Electrical devices
  • Mattresses

Die springs differ due to their high force. Die springs are engineered to provide predetermined pressure, meaning they are suited to applications involving extreme conditions, high temperature, high loads or heavy machinery, making them an ideal choice for applications which require high force within a limited area.

They can be engineered to consistently give predetermined physical force at certain compressions, ideal components, for example, in punching and pressing machines.
