Manufacturing process
GREENPOLYMER filament production starts with compounding and pelletizing. Formulation, color and drying are all done in our own plants.
Specific configuration of each GREENPOLYMER production line: to be verified by GREENPOLYMER.
Process
IllustrationRaw material inspection and drying
Resins, masterbatches, fibers and additives inspected; dried by material
Compounding
Twin-screw extruder compounding: toughening, reinforcing (carbon fiber, glass fiber), flame retardancy, color matching
Pelletizing and inspection
Pelletizing; flow, moisture and color inspected
Drying again
Dried once more before filament extrusion, to reduce bubbles
Filament extrusion
Filament extruded on a single-screw extruder
Cooling and sizing
Water bath temperature set by material to control ovality and internal stress
Inline gauging
Diameter and ovality measured continuously; the data adjusts haul-off speed
Haul-off and winding
Tension and traversing controlled; wound to net weight
Weighing and labeling
Every spool weighed and labeled with model, color number and batch number; RFID / NFC tags can be written for OEM
Drying and vacuum packing
Vacuum bag with desiccant, packed in color boxes and outer cartons
Final inspection and warehousing
Appearance, color, print results and mechanical properties spot-checked
