Import Extruder — Buy in Bulk from Supplier in China

The SJ65 Single Screw Extruder from Zhangjiagang Gaosheng Machinery Co., Ltd is a 30kW industrial machine designed for continuous extrusion of thermoplastics, food compounds, and recycled polymers. It features a 15kW cast aluminum heating ring system and variable frequency drive control for precise screw speed regulation, enabling stable output under varying load conditions. The machine is built for 24/7 operation in high-throughput environments and includes a hardened alloy screw with a L/D ratio of 25:1, standard for single-screw extruders in this class.

This extruder is configured for standard plastic processing grades such as PE, PP, and PVC, with optional barrel linings available for abrasive materials like recycled PET or filled polymers. The heating zones are independently controlled with thermocouple feedback, allowing temperature profiles to be tuned for material-specific melting points. Typical output rates range from 60 to 120 kg/h depending on material density and screw configuration, consistent with industry benchmarks for 65mm diameter units. The gearbox is oil-lubricated and rated for continuous torque output without overheating.

End users include plastic film manufacturers, food packaging producers, and recycling facilities that require consistent strand or sheet extrusion. The machine is shipped with a protective steel frame, waterproof tarpaulin cover, and standard export packaging. Trade terms include FOB Shanghai or CIF destination ports, with MOQ set at one unit. Custom configurations for voltage, screw design, or output die type can be requested directly with the supplier before shipment.
