2） Motor speed ( MAX)：1500RPM
4. Screw stem
1） Screw stem diameter：Φ91mm
2） L/D = 40:1
3） Screw stem with modular structure
4） The screw core shaft is made of 40CrNiMoA, and the screw thread components connect with the core shaft in an involute curve, which features high intensity, large load, and easy disassembly and assembly.
5） The screw components are made of high quality high-speed tool steel, W6MO5Cr4V2, that receives heat treatment with vacuum hardening at high temperature.
6） Whole hardness: HRC62-64
5.Charging barrel
1） The barrel body is made of #45 steel, and the "8" shape hole is lined with wearing proof alloy a-101（Fe - Cr - Ni –B +Carbide）, hardness: HRC60 - 64, barrel length: L = 360mm/section.
2.）The first cylinder is used for feeding materials, the 10th cylinder for extrusion, the 9th cylinder for vacuum and the other cylinders are of closed mouth type.
3.） Soft water circulation system
3.1 The barrel uses soft water cooling.
3.2 The soft water tank separates with the body, which facilitates cleaning and service.
3.3 Electromagnetic valveCEME9313 imported from Italy.

Test the fusing temperature with the fusing temperature thermal couple, and test the materials pressure with the pressure sensor.
7. Electrical control system
1) 3X380V，AC 50Hz
2) Main electric control components are Siemens products.
3) Control buttons are Schroder products from France.
4) Twin-screw stem motor is a DC motor with a power of 132KW，and the speed regulator in the twin-screw stem host machine is the British EUROTHERM.
5) The speed regulator in the feeding machine is the Japanese FUJI variable-frequency regulator.
6) The temperature control meter is a Japanese RKC product with intelligent double channels and a temperature control in each zone.
7) Pressure meter range: 0- 25Mpa.
8) The electromagnetic valve is imported from Italy CEME9313.
9) Heating is controlled by the temperature control meter via a solid-state relay with high-temperature wire.
10) The electric control cabinet controls the temperature control system, the driving system and the interlock control system.
8. 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 overcurrent, both the host machine and feeding machine should stop operation. |
