  • Die Springs

    View our range of die springs including light, medium, heavy and extra heavy load die springs - all in different colours. Every batch of springs is subject to a rigorous testing procedure to ensure that a consistent quality is maintained.

    When the components are pulled apart, usually from either side, the spring tries to hold itself together, causing the spring action until the force is stopped and it can return to its original form. Most tension springs are wound with an initial tension, this tension is the

    Spring Facts for Kids. Spring begins on March 21st or 22nd. The first day of Spring is called the Vernal Equinox. Vernal is Latin for Spring. Equinox is Latin for Equal Days. On the first day of Spring the sunrise and sunset are about 12 hours apart, everywhere on the Earth and the hours of daylight and night are almost equal. Daylight is a little longer.

    Alice Springs (Eastern Arrernte: Mparntwe) is the third-largest town in the Northern Territory of Australia. Known as Stuart until 31 August 1933, the name Alice Springs was given by surveyor William Whitfield Mills after Alice, Lady Todd (née Alice Gillam Bell), wife of the telegraph pioneer Sir Charles Todd.

    These Extra Heavy Load Die Spring (Yellow) are made of high tensile strength chromium alloy steels. Optimal wire cross section. Spring ends are ground square. Dimensional requirements remain consistent and measurably the same from one batch of springs to the next.

    A Spring’s Spring Rate. A spring’s Spring Rate is the amount of weight required to deflect a spring one inch. The lower the Spring Rate, the softer the spring. The softer the spring, the smoother the ride. If you’re still having trouble, think of it as a fat guy on a mattress. A fat guy on a

    Raymond Die Springs may be the most popular die springs in North America. There are 380 inch die springs and four color codes in this US Series. Blue is Medium Duty with the lightest pressure and longest travel to solid. Red is Medium Heavy Duty. Gold (Yellow) is Heavy Duty. Green is Extra Heavy Duty with the highest pressure and shortest travel.

    Nitrogen Gas Springs. Super Compact Series is ideal for applications that require high force and short stroke lengths. The bore-sealed construction of this series offers the highest force per diameter model from DADCO. Available in nine force models (from .4 ton to 18 ton) this series can suit a variety of well-designed die applications.

    Maximum spring compression is the "true maximum travel" of a compression spring also known as the maximum travel considering solid height or the safe travel distance which your spring can travel safely without any permanent set caused by fatigue and stress.


    Die springs from rectangular wire are a series of extra high quality compression springs for use in press tools, valves, couplings, fixtures and other applications where high loads are required in a confined space. For each dimension, there are 4–5 different force classes to choose from.

    Linear rate springs: Linear springs are the easiest to understand. When you think of a spring, this is typically what you are thinking of. As the load on the spring increases, the spring compresses an amount directly proportional to that load. So, if the spring is rated at 100lbs per inch, in will compress 2 inches when 200lbs is applied.

    Die Springs. Products > MOULD COMPONENTS > General Mould Components. ISO Standard round Die Springs with rectangular cross-section. Ongoing research and development, along with strict quality assurance procedures in compliance with ISO 9001, ensure very high levels of dimensional accuracy, durability and reliability.

    Extension Spring is a close-coiled helical spring that offers resistance to a pulling force. Torsion Spring exert pressure along a path which is a circular arc, or, in other words, providing torque. Sometimes these springs are called torsion springs, motors springs, power springs.

    Springback – a deep-drawn part springs back after the forming process is complete. Through the application of new materials, the number of problems increases. Forming parts made of these materials are more affected by springback than parts made from conventional deep-drawn steel.
