Light Load Green Round Wire Die Spring
Berger Tools die springs are heavy duty metal compression springs specifically designed to be used in a die set tool or as heavy-duty coil springs in any heavy load application. They can be manufactured from either rectangular or round wire. They are divided into a rising load range and colour coded for easy identification, shown in the table below. They make an excellent choice where a high force is needed in a limited space.
Our precision spring manufacturing process is aimed at guaranteeing the best dimensional and functional characteristics for our springs, as well as performance. In order to achieve this, special manufacturing techniques, advanced heat treatments and the best inspection and test equipment are used.
The whole process is closely monitored and allows for complete traceability. 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 fit over the rod. Continual research and development result in the best quality and longest life springs available.
Berger Tools ISO die springs are all shot peened. Shot peening is a process which greatly enhances the fatigue strength of the spring and is achieved by blasting the surface with shot particles at high force. The effect of this process is to prevent microscopic surface cracks from forming and in doing so drastically extend its resulting service life.
Berger Tools are the exclusive UK & Irish distributor for Special Springs, for your complete range of compression die springs. The springs are manufactured to European Standard ISO 10243 where applicable and we keep a large range of sizes in stock, ensuring that next day delivery is available for most items. We are also able to quote to drawing for non-standard items.
