Abstract: A small sized injection molding machine by which a molded product can be produced with a desired level of precision with simple control. An injection molding machine with: a longitudinal injection cylinder to which stick-shaped molding materials are sequentially supplied in line from the upper side, the lower end of which is formed into a nozzle shape, and the lower side of which is constituted by a material having a good heat retaining property; a heater which heats the lower portion of the injection cylinder; and a pressing shaft which presses the stick-shaped molding materials downward. When the stick shaped-molding material located at the uppermost side is pressed by the pressing shaft, the molding material located at the lowermost side which has already been completely melted, is injected into a cavity, and the heat from the heater is transmitted to the die side through a nozzle touch portion.

Abstract: An output of heater means of a tube shaped heater device is set to melt a compound body P suitable for injecting it into a mold cavity. The conditions of temperature and the viscosity of the compound body P is adjusted in a through aperture suitably for theirs injection molding process. Upon descended a pusher shaft, the molten, compound body P is injected by the shaft into the gate and further into the cavity. After the compound body P reaches there, it solidified and changed to an article S.
