Conical Twin Screw Extruder
We adopts Siemens standard motor and speed controlled by ABB inverter. The control system adopts Siemens PLC control or button control. The conical twin screw extruder of the pipe line adopt high efficiency screw & barrel, gearbox with self-lubrication system. With touch screen (optional) is more intelligent and easy operation.
Mould
The mould has spacious flow channel design to guarantee high extrusion capacity and good melting effect.
It is made and inspected by the experienced manufacturer. The optimized temperature control and flow channel design ensures precise melt temperature control.
Vacuum Calibration & Cooling Unit
Both of vacuum tank and spraying cooling tank adopt stainless 304 steel. With adequate length of spraying and cooling will improve the cooling efficiency; Auto water temperature control system is adjusted according to the temperature sensing.
Haul-off Machine
The six caterpillar on the haul-off machine ensures produced pipe running stably and steady. The haul-off units can make tailored hauling model based on certain production requirement by adjusting the general control.
Cutter
The high accuracy encoder ensures a precise and stable cutting length. With PLC control system, it can be cut by manual operation according to the specific application.
Belling machine
The line has automatic online socketing system running stably and intelligently. It’s heating and cooling is high-efficient and precise. The pipe socket is round and smooth. It provides two heating position for on-time belling by high line speed.
