Die Springs

Die springs are heavy-duty compression springs engineered for use in stamping dies, press tools, and industrial fixtures. Wound from rectangular wire to maximise load capacity in a compact space, they are colour-coded by load class in accordance with ISO 10243 or Raymond NAAMS. Use the filters or ask Springy to find the right spring for your needs.
