Abstract

Embodiments of the disclosure relates to a die design and its construction, more particularly related to a replaceable die inserts for manufacturing an engine valve by metal forming process. The die is characterized in that a holder at bottom of the die, said holder comprising a top surface having a recess and a plurality of holes around the recess, a bottom surface configured to mount onto a machine, a bore at its centre; a support plate mounted at the recess of the holder; a die insert consisting a cavity having shape of the engine valve and is mounted over the support plate; a inner casing consisting a cavity matching with shape of the die insert for enclosing the die insert; a clamping means connected to the holder using fasteners, wherein the support plate, die insert and the inner casing are positioned between the clamping means and the holder.
