PURPOSE:To execute a manufacture of a billet and a manufacture of an extrusion product by one equipment, by providing a displaceable container on an injection molding position and an extrusion molding position. CONSTITUTION:A holding device 13 is made to ascend, and the inside of a container 1 is packed with a preform material. An injection sleeve 6 is inclined together with an injection cylinder 7, a chip 7b is made to descend and a molten metal is supplied into the sleeve 6, and it is returned to a vertical state. A hydraulic fluid is supplied into a ram 9, the sleeve 6 is made to ascend, and its upper end is fitted into the container 1. Before a molten metal in the sleeve 6 is injected by the chip 7b by an operation of the cylinder 7, the inside of the container 1 is formed to a vacuum state, the injection is executed and it is impregnated in the preform material 31. In this state, a billet is formed. Subsequently, the holding device 13 is made to ascend, the sleeve 6 is made to descend, the container 1 is rotated by 90 deg., and the center of the container 1 and the center of a die 11 and a stem 12 are placed on the same axis. When the stem 12 advances in a state that the container 1 and the die 11 have been fitted to each other, an extrusion molding products are is obtained by the die 11.
