2)The first barrel is used for feeding materials; The 6th and the 10th barrel for vacuum, the 11th barrel is for extrusion.
3)The other cylinders are of closed mouth type.
7. Heating system
8. Vacuum Degasifier
9. Soft Water Circulatory System
10. Interlock control system
1) Only after the oil lubrication system interlocks with the host machine, i. e., the oil pump starts up, can you start up the host machine.
2) Only after the feeding system interlocks with the host machine, i. e., the host machine starts up, can you start up the feeding machine.
3) When the pressure system interlocks with the host machine, i. e., reaches overpressure, both the host machine and feeding machine should stop operation.
4) When the electric current interlocks with the host machine, i. e., reaches over current, both the host machine and feeding machine should stop operation.
