Single Screw Extruder Application

  • Pipe and profile materials:  PVC drainage pipes, PE water supply pipes, PPR hot water pipes, door and window profiles, etc
  • Sheet and board materials:  PET packaging sheet, PS foam board, PC endurance board, PP hollow board, etc
  • Granulation and recycling:  cleaning and granulation of recycled plastics, color masterbatch, filled masterbatch, modification of engineering plastics, etc
  • Specialty products:  high-precision items such as medical catheters, fiber optic sheaths, and 3D printing filaments
  • In addition, plastic injection molding machines are the most common single-screw extrusion equipment

 

Advantages Of Single Screw Extruder

Excellent plasticizing performance:

  • Three-stage screw design (conveying stage, compression stage, metering stage) tailored for special materials
  • Customizable split screw structure to enhance mixing efficiency and exhaust performance

High efficiency and energy saving:

  • Equipped with Omron or RKC temperature control system and variable frequency drive motor, it achieves dynamic matching of energy consumption
  • The barrel is made of high-quality alloy steel lined with a bimetallic layer or subjected to nitriding treatment, making it wear-resistant and corrosion-resistant, thus ensuring a longer service life
  • Modular design, flexible adaptation to various processes, from MSI25 laboratory micro-machines to MSI250 large industrial units, covering a full range of product specifications
  • It supports multiple functions such as multi-layer co-extrusion, lateral feeding, and vacuum degassing, meeting the processing needs of various thermoplastic materials such as PP, PE, PVC, PET, and ABS
  • Intelligent control, easier operation. Equipped with PLC+touch screen centralized control system for real-time monitoring
