B.ZT-III Automatic Shoulder Injection Machine is a new type of hose shoulder injection equipment which developed by our company.The shoulder injection machine uses servo motor drive，Human-machine operation of PLC intelligent control touch screen ,  integrat machine, electricity and gas,which with the advantage of high efficiency, low energy consumption, easy operation, fault alarm, no waste.Using injection molding, spit material, extrusion molding, welding way to inject plastic shouders for plastic composite pipe and plastic pipe.The shouders are with beautiful appearance ,very strong and without any seam line.

This machine can connected with B.GLS-III aluminum-plastic composite flexible Pipe Making Machine which produced by our company automatic, become an automatic tube production line.It  also can be used with other pipe-maling machine supporting production of plastic hose.

This machine also with the advantages such as  highest utilization rate of plastic particles of raw materials, low labor intensity, more safety,etc.

This machine mainly include automatic tube filling mechanism , declared the amount of injection molding, plastic spitting device, mold forming mechanism,the Ejection mechanism, automatic discharge  mechanism.
