Product Introduction

Conical twin-screw granulation extruder is a special integrated extrusion and pelletizing equipment for laboratory research and small-batch polymer modification. Developed specifically for PVC and various heat-sensitive polymer materials, it integrates extrusion, vacuum degassing, cooling, air drying and pelletizing in one compact unit. The machine features small footprint and convenient commissioning. All core systems including transmission unit, screw and barrel, heating and cooling system, vacuum exhaust system and intelligent control system are independently designed and manufactured. The differential conical screw structure provides high torque and excellent mixing and plasticizing performance. Widely applied in universities, research institutes and enterprise R&D centers for formula development, new material modification and small-scale trial production, it delivers uniform and stable plastic pellets.
