PROBLEM TO BE SOLVED: To obtain a plastic molding machine which does not pollute environment by the scattering of a powdery pigment when the pigment is used, can shorten a cleaning time, and can produce various products in small amounts. SOLUTION: A main raw material hopper 1 is connected to a main tube 3 through a shooter 2. The powdery pigment from a pigment hopper 14 is supplied to an extruder 17 with the inside of a powdery pigment charging tube 14 made a passage. The powdery pigment charging tube 14 is fitted insertably/detachably into the main tube 3, The pigment adherent to the inner wall can be removed by detaching the tube 14. The pigment discharged from the discharge opening of the tube 14 is supplied to the extruder 17 while being surrounded by main raw material pellets charged from the hopper 1 into the main tube 3 through the shooter 2.
