      After the feed zone, the screw flight depth is gradually reduced, forcing the plastic to compress. The work is converted to heat by shearing the plastics, making it a semifluid（半流体） mass.

Gas tungsten arc welding is performed with the heat from an electric arc discharged between the workpiece and a nonconsumable（不熔化）  electrode made of tungsten.

This process, like GNAW(gas metal arc welding), is gas-shielded arc welding, where an atmosphere of inert gas is maintained around the arc and no flux（熔剂） is used. The process is often called tungsten inert（惰性） gas welding.
       In the metering zone, additional heat is applied by conduction from the barrel surface. As the chamber in front of the screw becomes filled, it force the screw back, tripping a limit switch that activates a hydraulic cylinder that force the screw forward and injects the fluid plastic into the close mold.

经过进料区后，螺丝进入螺孔深度逐渐减小，使得塑料被压缩。这一工作是通过剪切使塑料变热，变成了半融熔团絮状。
钨极氩弧焊是通过在工件与非熔化钨电极间的电弧放电产生的热量并传递完成的。
这以工艺，像氩弧焊，是气体保护氩弧焊，在电弧和溶剂之间保持一种气氛，这种工艺叫作钨极惰性气体保护焊，也叫钨极氩弧焊。
