Innovations in cold forging die design

Abstract The demand of the market to the major industrial cold forgers for the development and production of complicated net shape parts at fairly low unit costs requires innovative new die designs for the optimisation of die deflections. The high-stiffness STRECON ® E + containers influence the stresses, strains, and deflections in critical dies so that die lives can be improved by factors of 3–10 and die deflections reduced by 30–50%. Application examples for bevel gear dies, planetary gear wheel dies, and spline dies show how the STRECON ® E + containers can be applied to such critical dies in an innovative way.
