Simulation analysis was made on the extrusion forming of a micro-gear by using the Deform software to optimize the key die structure and forming conditions. A hot extru-sion die for the micro-gear with modulus m=0.125 mm, pressure angle A=20° , tooth number z=6 and addendum circle diameter d=1 mm was designed by splitting method in which H62 brass was used as the blank and positive hot extrusion was applied under 650℃ of isother-mal conditions.
