SJ Series Single Screw Extruder
The set can be used for extruding theromo-plastic such as soft hard polyvinl chlorid(PVC) and polystyrene(PE). Coordinatesd with the appropriate auxiliary machine, (including the lead of former), it can produce many kinds of plastic products such as film pipe, plate, braid, belt as well as granule.
single screw extruder is mainly composed of barrel screw, momentum driving system, heating, cooling, and electric controllers etc. It is imainly used in plasticizing and extruding of PVC, PE, PP, ABS, PS, PET pipes, plates, sheets, film, profiles, granulates and other plastic products.
It is advanced in designed, high in output, good in plasticization and low in energy consumption. The involute gear driving is characterized by low noise, stable working, big bearing capacity and long service life. DM screw can made by client's demand. The motor, eletrical appliance, contactor and temperature controllers, etc could be adopted by buyer's requested.
Features:
1. plastic single screw extruder is mainly used for extruding PVC,PE, PP, and ABS thermoplastic plastics.
2. plastic single screw extruder Combined with corresponding auxiliary machinery (including molding head), it can process many plastic products: films, pipes, bars, plates, wire, insulating course with cable.
3. plastic single screw extruder can be used for granulating.
4. plastic single screw extruder adopting involute gear drive, it mainly features advanced design, high quality, excellent plasticization, low energy consumption, low noise, stable operation, large loading capacity, long service life, etc.
5. plastic single screw extruder barrel screw and gear boxes are all made with high standard quality, so we can guarantee you the quality compared with other suppliers.
6.DC/AC machine, Eurothrm governor, Temperature controller is Japanese RKC. Contactor SIEMENS. DC speed control system (Eurothrm). All digital DC converter. AC machine, we adopt ABB inverter.
7.Speed reducer: The gear and the axis class components have used the high strength alloy steel material quality.
