Features:
1、Stable Output
The output capacity can be configured from about 80 kg/h to 800 kg/h depending on screw diameter, material type, heating power and pelletizing method. This range is suitable for factories that need steady extrusion rather than complicated material compounding. For buyers processing PE, PP, PVC or recycled plastic materials, stable output helps reduce production interruption, improve order delivery planning and maintain more predictable pellet supply.
2、Single Screw Design
The machine uses one main screw for material feeding, melting, compression and conveying. The screw structure can be adjusted according to plastic type, melt flow and processing purpose. A properly matched screw helps reduce unstable feeding, incomplete melting and excessive motor load, which are common concerns in basic extrusion production.
3、Controlled Heating
The barrel can use multi-zone temperature control to manage heat from the feeding section to the extrusion outlet. Each zone supports more accurate melting behavior, helping the operator avoid material burning, insufficient plasticization or unstable discharge. For long production runs, stable heating control is directly related to pellet quality and machine efficiency.
4、Simple Maintenance
The overall mechanical structure is easier to inspect and maintain than more complex extrusion systems. Gearbox, motor, screw, barrel, heater and cutting parts can be checked in a more direct way. This helps factories reduce downtime, especially in markets where technical workers need equipment that is practical to operate and maintain.
Application:
1、Plastic Recycling Plants
Plastic recycling plants can use Single Screw Extruder Machine to process washed PE, PP or similar recycled materials into reusable pellets. The machine is suitable for relatively clean materials that do not require strong compounding. Stable melting and continuous conveying help recycling factories reduce manual handling and prepare pellets for downstream film, pipe, sheet or injection molding production.
2、Film Material Processing
Film material processors often need extrusion equipment for LDPE, HDPE or PP film reprocessing. The single screw design supports stable melting of film flakes after crushing and cleaning. With suitable feeding and temperature control, the machine helps reduce bridging, uneven melting and unstable pellet cutting, which are common issues when processing lightweight film materials.
3、Pipe Production Supply
Pipe material factories can use this machine for plastic pellet preparation or basic extrusion support before pipe manufacturing. Stable output and controlled plasticization help maintain material consistency, which is important for pipe wall thickness, surface quality and long production runs. For project buyers, simple operation also reduces commissioning pressure.
4、Profile Manufacturing
Profile manufacturers handling PE, PP or PVC materials need equipment that supports continuous extrusion with controlled melt flow. Single Screw Extruder Machine fits this production direction because it delivers steady conveying and easier process adjustment. This helps factories manage daily orders for construction profiles, edge strips and other plastic profile products.
5、Sheet Extrusion Preparation
Sheet production factories may use single screw extrusion equipment for pelletizing or material preparation before sheet forming. The machine helps convert suitable plastic waste or raw material mixtures into more consistent pellets. For buyers producing packaging sheets, industrial sheets or utility plastic sheets, steady pellet quality helps reduce downstream processing instability.
