Single Screw and Barrel for Plastic Extruder Machine
Multi-layer Co-extrusion Machine
1: Polestar Machinery Can Provide Multi-Layer Co-Extrusion Equipment For The Production Of Multi-Layer Oxygen Barrier Pipes, Glass Fiber Reinforced Multi-Layer Pipes, Multi-Layer Heat Shrink Pipes, Ultra-Quiet Drainage Pipes, Etc.
2: The Multi-Layer Co-Extrusion Pipe Production Line Is Mainly Used To Produce Composite Pipes Such As PE Pipes, PPR Pipes, PERT Pipes, Silicon Core Pipes, Etc., Using Multi-Layer Co-Extrusion And One-Step Forming.
3: The Specially Designed Adjustable Compound Co-Extrusion Head Can Quickly Ensure The Uniform Compounding Of Multi-Layer Plastics And Media, And The Ideal Thickness Of Each Layer Can Be Quickly Obtained Without Adjusting The Extruder Speed.
4: The Special Design Of The Mold Ensures The Low-Temperature Plasticizing Effect, And The Special Temperature Control System In The Core Ensures The Appearance And Quality Performance Of The Co-Extruded Pipe.
5: A Variety Of Control Systems Are Available For Users To Choose From. The Entire Production Line Adopts PLC Programmable Computer Control System To Ensure High-Speed Synchronous Control And Smooth And Reliable Operation Of The Entire Production Line.
