Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an in-line screw type injection molding machine having a screw with excellent resin feeding performance of a feeding zone. SOLUTION: The feeding zone of a screw is so surface treated as to reduce dynamic frictional coefficient as compared with that of the other zone (a compression zone and a metering zone) of the screw.
