It has the advantages of high production efficiency, low energy consumption, easy operation, automatic fault alarm, stable performance, and no three wastes. The B.ZJ-I type automatic shoulder injection machine for injection, spit, extrusion and welding is a new type of high-tech hose shoulder injection machine independently developed by our company. All actions of this type of shoulder injection machine are controlled by large-scale PL.C intelligent control touch screen display man-machine actual operation, integrating machine, electricity and gas, the combined way and method can be used to inject plastic into aluminum-plastic composite pipe and plastic pipe shoulders. The shoulders produced have no clamping stitches, and the appearance is elegant and stable. This equipment can be matched with the B.GLS-II composite hose pipe-making machine produced by our company to form a fully automatic pipe-making production line, and can also be matched with other pipe-making machines to produce plastic hoses. Compared with the shoulder injection machine used in my country today, this equipment has the characteristics of higher material utilization rate and lower labor intensity.

The equipment mainly includes: full servo operation mechanism, automatic pipe feeding mechanism, quantitative plastic injection mechanism, mold clamping and forming mechanism, mold release and separation mechanism, automatic pipe unloading mechanism, automatic feeding mechanism, etc.
