Production Line Setup

Granulation & Compounding Lines

Our granulation and compounding lines are designed to serve both sustainability-focused recyclers and high-value compounders. These systems enable efficient reprocessing of plastic waste and precise formulation of customized plastic materials such as filler masterbatch, color masterbatch, biodegradable resins, and engineering polymers.

Applications

Plastic Recycling & Regranulation
Post-consumer LDPE, LLDPE, HDPE film recycling
Rigid plastic reprocessing (PET, PP, ABS, PS)
Industrial scrap recovery and inline waste recycling
Masterbatch Production
White, black, color masterbatch
Filler masterbatch (CaCO₃, talc, TiO₂-based)
Additive masterbatch: UV stabilizers, antioxidants, antistats
Biodegradable Compounding
PLA, PBAT, PBS compounds
PLA + starch blends
Water-soluble or compostable granules for film blowing and extrusion
Engineering Plastics & Custom Compounds

Plentiful Choices

Key System Features

Extrusion Configuration

  • Twin-screw extruders (co-rotating parallel or conical) for compounding
  • Single-screw extruders for general recycling and low-shear processing
  • L/D ratios: 28:1 – 52:1 for different process intensities

Feeding & Dosing

  • Main hopper with forced feeding system for light bulk density materials
  • Side feeders for fillers, fibers, powders
  • Liquid/paste dosing pumps for additives and modifiers

Degassing & Filtration

  • One or two vacuum vents for moisture and volatile removal
  • Melt filtration systems: manual or automatic screen changers
  • Melt pressure sensors and backflush systems

Pelletizing Options

  • Strand pelletizing for compounds and rigid polymers
  • Water-ring pelletizing for films and flexible resins
  • Underwater pelletizing for high-output or sticky materials

Post-Processing

  • Vibrating classifier, dewatering units, silo storage
  • Integrated inline recycling loops
  • Cooling systems: water bath, air knife, centrifuge dryer
