Keen to expand its standard ranges, is Lee Spring, supplier of ex-stock die springs, and in particularly its Die Spring catalogue, which has been extended with 71 new items. These new items in music wire or OTCS (chrome silicon steel) reduce the gap between different standard lengths with additional options over 6” lengths, so making it easier to choose a suitable standard spring.
New lengths include 4, 5, 6, 7, 7.5 and 8” with 8 different outer diameters to suit medium (grey), medium-heavy (purple), heavy (black) and extra heavy duty (orange) loadings.
Similarly to other Lee Spring die springs the new sizes are generally priced at 1/3 to 1/2 less than the cost of comparable rectangular wire springs, offering users a distinct value advantage. In independent testing conducted by the Institute of Spring Technology, Lee Spring’s die springs demonstrated a life-expectancy equal to traditional rectangular wire die springs.
Ex-stock die springs are not solely used in dies but find application in clutches, brakes, farm machinery and aircraft mechanisms. They are suited for use as die springs or as heavy duty compression springs for any high stress, heavy load application.
