Abstract
Conform extrusion is suitable for producing long products such as electric wires and heat exchanging pipes etc. This processing method is given forming power by rotating wheel. And the metal whose flow direction by abutment is supplied to a container, and is extruded from a die. However, this manufacturing method has the problems that metal flow becomes complicated and that oxidization film is caught in products, because the flow direction changed rapidly by abutment. Then, in this study, model experiment which by using plasticine is carried out and observed the metal flow. It is clean that geometries of abutment and container have much effect on the load of abutment and one of die.
