Following the mature hot forming technical accumulation in the brick machinery sector, Bohai Machinery expands its product layout and launches SJ series single-screw plastic extruders and complete auxiliary production lines, providing reliable processing equipment for plastic recycling, pipe, profile, packaging material manufacturing enterprises worldwide.

Our SJ45, SJ50, SJ65 mainstream extruder models are designed for thermoplastic raw materials such as PE, PVC, PP, suitable for plastic pelletizing, water pipe, cable sheath, packing belt, plastic sheet and film extrusion forming. Equipped with hardened tooth surface reducer and wear-resistant nitriding screw, the equipment runs stably under long-term high-load working conditions, featuring low noise, high transmission efficiency and obvious energy-saving advantages compared with traditional extrusion equipment.

Supporting complete plastic auxiliary equipment includes plastic crushers, horizontal mixing machines, automatic feeding machines, cooling water tanks and pull-strip pelletizers. Customers can freely combine different units to build semi-automatic or fully-automatic plastic recycling production lines, turning waste plastic materials into reusable plastic particles to realize circular economic benefits.

Each set of plastic extrusion equipment supports customized voltage, mold specification and intelligent PLC control system upgrade, meeting the access standards of different national industrial power grids. We provide complete export customs clearance documents including CE certification, factory test reports and origin certificates to simplify overseas customers’ import procedures. From equipment parameter matching to post-sale spare parts supply, Bohai Machinery builds a global after-sales service system to guarantee continuous stable operation of customers’ hot forming production lines.
