The single screw extruders produced by our company mainly include the following types
Filler Masterbatch Pelletizing Line
Filler masterbatch pelletizing line adopting twin-screw or single screw structure, twin-screw model, suitable for blending modified materials. The single screw machine is designed specifically for high filler, with excellent dispersion effect and a production capacity of 800-1000KG/H.
Black White Masterbatch Pelletizing Line
The black white masterbatch pelletizing line adopts a modular design, with flexible adjustment of screw configuration, cylinder structure, and aspect ratio to meet various process requirements.
Simplicity and Cost-Effectiveness
Single screw extruders are relatively simple in design and construction, which makes them cost-effective to manufacture, operate, and maintain. They are often more affordable compared to their twin-screw counterparts.
Wide Range of Materials
Single screw extruders can process a broad range of materials, including plastics, rubber, metals, and food products. This versatility makes them suitable for various industries, such as plastics manufacturing, food processing, and pharmaceuticals.
Easy to Operate
These extruders are user-friendly and relatively easy to operate, making them suitable for operators with varying levels of expertise. Their straightforward design simplifies the learning curve.
Compact Design
Single screw extruders have a compact design, which is advantageous for facilities with limited space. They can be integrated into production lines more easily due to their smaller footprint.
Energy Efficiency
They are often energy-efficient, consuming less power compared to twin screw extruders, especially when processing certain materials. This can result in cost savings over time.
High Throughput
Single screw extruders can achieve high throughput rates, making them suitable for applications that require large-scale production. They can process significant volumes of material in a relatively short time.
Low Maintenance
Their simple design reduces the complexity of maintenance and repairs, resulting in reduced downtime and lower maintenance costs.
Consistent Output
Single screw extruders offer consistent and uniform output, making them ideal for applications where product quality and consistency are paramount.
Pipe extrusion: Suitable for PP-R pipes, PE gas pipes, PEX cross-linked pipes, aluminum-plastic composite pipes, ABS pipes, PVC pipes, HDPE silicon core pipes and various co-extruded composite pipes.
Sheet and sheet extrusion: Suitable for the extrusion of PVC, PET, PS, PP, PC and other profiles and sheets.
Profile extrusion: Adjusting the speed of the extruder and changing the structure of the extruder screw can be used to produce various plastic profiles such as PVC and polyolefins.
Modified compounding: It is suitable for compounding, modifying and enhancing compounding of various plastics.

It is not allowed to run empty to avoid scratching the barrel. During no-load test run, the speed shall not be higher than 3rpm.
Metal or other sundries shall be strictly prevented from falling into the hopper to avoid damaging the screw and barrel.
The equipment shall always be kept clean and well lubricated. Wiping and lubrication shall be done well at ordinary times. Pay attention to the clean production environment.
Before starting up each time, check whether there is material leakage and air leakage at the connection of the extruder, especially at the connection of the upper and lower stages and at the tail of the lower stage, that is, at the connection of the extruder and the transmission box.
In case of abnormal noise during the operation of the extruder, stop the extruder immediately for inspection or repair.
Regularly calibrate the temperature control instrument, and check its correctness of adjustment and control sensitivity.
The inner wall of the cooling water pipe attached to the extruder is easy to scale, and the outer surface of the Teflon pipe or steel wire pipe is easy to rust. Careful inspection shall be carried out during maintenance.
Timely check the locking of all fasteners of the machine, such as the fastening screws of the heating ring, the terminal blocks, and the external shield elements of the machine.
In case of power supply interruption, all potentiometers must be reset to zero (that is, the upper and lower main machine speed must be reset to zero and the drive and heating must be stopped.
When the extruder needs to be out of service for a long time, anti rust grease shall be applied to the working surfaces of the screw, the die and the head.
