PURPOSE: An injection molder is provided to produce a beautiful product in external appearance by forming natural patterns in several colors with low cost. CONSTITUTION: A screw apparatus of an intruder comprises a transferring unit(50); a melting unit(60) and a pressurizing head unit(70). The transferring unit forms a front portion of a shaft(32). A screw wing is formed to an outer peripheral surface of the shaft of the transferring unit. The melting unit forms a rear portion of the shaft. The melting unit does not have the screw wing. The pressurizing head unit is a rear end of the melting unit. Thereby, raw material transferred to the molding unit by the transferring unit is supplied to the pressurizing head unit without mixing fully. Therein, natural patterns in various colors are made by injecting materials without mixing fully. A slip member(66) is installed to the outer peripheral surface of the shaft in a tubular shape. Therein, the slip member prevents two color materials from mixing with a rotating shaft.
