A screw(1) includes a supply unit(2), a compression unit(3), and a metering unit(4), and compulsorily delivers resin material through main spiral blades(5) formed in each unit. The compression unit has auxiliary spiral blades(6) formed between the main spiral blades. The metering unit has first to third auxiliary spiral blades(9a,9b,9c) formed between the main spiral blades. |
