采用双挤胶系统配备特殊的螺杆螺筒，螺杆、料筒并列结构，交替或共同实现熔胶—射胶动作，使射胶口保持连续高压注射状态，并根据模腔容量自动调节射胶量，不受单一机筒容量的限制。因此大大提高射台对成型产品的适用范围。

　　Injection joint equipment for internal ribbed tube cracker pipe steel strip pipe

　　The double extrusion system is equipped with special screw screwdriver, screw and material cylinder juxtaposed structure, alternately or jointly to realize melt glue-glue injection action, so that the injection edge can maintain a continuous high pressure injection state, and automatically adjust the amount of glue according to the cavity capacity, which is not limited by the capacity of a single cylinder. Therefore, the application range of the shooting station to the molding product is greatly improved.
