Single screw plastic extruder machine can process all kind of plastics products with auxiliary machines concerned, such as film, pipe, stick, plate, thread ,ribbon, insulating layer of cable, hollow products and so on. Single screw extruder is also used in graining. Single screw plastic extruder design is advanced, production capacity is high, plasticization is good, and energy consumption is low. This plastic extruder machine adopts hard gear surface for transmission. Our plastic extruders have a lot of advantages.
We also manufacture many kinds plastic extruders such as plastic machine extruder sj25 mini extruder, small extruder, lab plastic extruder, plastic pellet extruder, twin screw extruder, PE extruder, pipe extruder, sheet extruder, pp extruder, Polypropylene Extruder, pvc extruder and so on.
1. Long groove between feed throat and screw to improve output highly
2. Accurate temperature control system on feed section to match different plastics
3. Unique screw design to achieve higher plasticizing and products quality
4. Gearbox of high torsion balance to realize stable running
5. H shape frame to decrease vibrating
6. PLC operation panel to ensure synchronization
7. Energy conservation, easy for maintenance

Based on 33:1 L/D ratio for screw design, we have developed 38:1 L/D ratio. Compared with 33:1 ratio, 38:1 ratio has advantage of 100% plasticization, increase output capacity by 30%, reduce power consumption up to 30% and reach almost linear extrusion performance.
Apply program developed by our company, have English or other languages to be input into the system.
Screw is designed with special structure, to ensure good plasticization and mixing. Unmelted material can not pass this part of screw, good plastic extrusion screw.
Feeding part of barrel use spiral structure, to ensure material feed in stable and also increase feeding capacity.
Ceramic heater ensure long working life. This design is to increase the area which heater contact with air. To have better air cooling effect.
Gear accuracy to be ensured 5-6 grade and lower noise below 75dB. Compact structure but with high torque.
