Die Springs are compression springs but are engineered to consistently give predetermined pressure at a given compression, therefore making them ideal for applications involving high loads or extreme conditions, such as die sets and progression tools.
Our large range of high quality springs includes ISO - European Standard, JIS - Japanese Standard, Oval - USA Standard, and turret springs.
They can be manufactured from either rectangular or round wire, and to various standards and are divided into a rising load range, colour coded for easy identification. Special manufacturing techniques, and advanced heat treatments are used to provide the best possible quality and length of service.
The spring ends are closed and ground to create a reliable, flat, maximum load bearing surface. Careful engineering ensures continuity and provides uniform spring performance. Dimensional requirements remain consistent and measurably the same from one batch of springs to the next giving certainty that the OD will work freely in the prescribed hole and the ID will work over the prescribed rod. Continual research and development result in the longest life springs available. The whole process is closely monitored and allows for complete traceability.
