Abstract

PURPOSE:To eliminate the need for cutting work and to improve workability by using a extrusion die having a bearing part given a twist to extrude and by cutting the twist formed extruded material having a prescribed sectional shape into a prescribed dimension. CONSTITUTION:The extrusion die 1 having the extruding opening 2 of sectional shape corresponding to the twist formed part A is used. This die 1 is equipped with the bearing part 1a given the twist of a prescribed lead. By using this to extrude, the extruded material 3 having the sectional shape corresponding to the extrusion opening 2 and given the twist of the prescribed lead is formed. This lead of the twist becomes smaller when the extruding speed is set fast and the lead becomes larger when the speed is set to be slow. This extruded material 3 is cut into a prescribed length to obtain the formed part A. By this method, because the cutting work to form the spiral blade is needless, the workability is excellent ot fit mas-production to improve the yield of the materials.
