Die Springs
Die springs are designed to operate in extreme conditions and are crafted from rectangular wire to provide extra strength and durability. Due to their unique design, die springs can deliver high loads in a confined space, making them ideal for use in machinery and fixtures where space is limited. In addition, these springs are perfect for use in heavy-duty applications such as press tools, valves, and couplings and can be used in various industries.
At Lesjöfors Stock Spring US, we manufacture die springs of the highest quality using advanced manufacturing techniques, ensuring that our products meet the highest standards for performance and reliability. Our die springs are designed to withstand even the most demanding applications, providing long-lasting performance and reliable operation.
Advantages of a Die Spring
Die springs are highly advantageous compression springs designed to maintain a consistent output force, even when subjected to high temperatures or countless repetitions of high force. One of the benefits of these springs is their rectangular profile, which allows for a shorter solid length, making them suitable for a broader range of applications due to their increased deflection capacity.
Different die springs are available in the Lesjöfors Stock Spring US range with varying load capacities and load cycle limits. In addition, each dimension of our die springs offers seven distinct force classes, which can be viewed in our wire springs catalogue.

In order to achieve the best characteristics and lifecycle, we follow a well-developed production process.
- We choose a special alloy which has been created, improving heat resistance, and decreasing relaxation. The nearest similar materials are EN 10089 and EN10270-2.
- Shallow surface decarburization free from surface defects.
- Using a rectangular profile in manufacturing die springs allows for a reduced solid length, resulting in a greater capacity for deflection.
- Increasing the allowed stress level results in a significantly extended operating life.
- Precise tolerances enable an accurate fitting within limited space.

Lesjöfors Stock Spring US’ Manufacturing Process
At Lesjöfors Stock Spring US, we have a well-established and advanced process for producing high-quality die springs with superior features and extended lifecycles. Our team has developed a specialized alloy that enhances heat resistance and relaxation resistance. Although not identical, this alloy is comparable to materials such as tempered steels like EN 10089 or EN 10270-2. As a result, our die springs have exceptional surface quality, free from decarburization and other defects.
Our manufacturing process ensures that we meet strict tolerances, providing our customers with reliable and precise die springs that fit perfectly into existing spaces.
Die Spring Applications
Since die springs are very similar to compression springs, except with higher pressure and heat resistance, you may think that choosing die springs over standard compression springs is the natural choice to ensure you use the best spring available. However, whilst die springs are excellent when used in their intended environments, they are bulky and not cost-effective when considered for use in an application suitable for standard compression springs. If you are not sure which type of spring you need, please don’t hesitate to contact one of our wire spring experts by calling +1 (860) 584-0594. We will be more than happy to offer advice.
Industry Applications of Die Springs
Although square-coiled springs may appear rare, die springs are widely used in various industries. These springs are commonly found in the automotive, transport, and agriculture sectors, where heavy machinery is required to operate under high forces. With their unique rectangular profile and ability to consistently output force under compression, die springs are well-suited to many applications that require high loads in a confined space.
At Lesjöfors Stock Spring US, we use our refined manufacturing process to produce die springs with excellent characteristics and high lifecycle limits, ensuring our products can withstand the toughest conditions across various industries.
