3D Printer Plastic Filament Extruder Extrusion Line
1.Produce process
1) Before produce extruding filament ,we will dry ABS and PLA for a
enough time (3-5 hours).
2)Mix with colors masterbatch or colors powder, all which .
3)Adjust temperature and dragging rate , make filament diameter
range at 1.6-1.8mm/2.8-3.0mm, roundness +/-0.05mm, each spool net
weight 1kg+/-0.02kg
2.About waste & recycle
Much time you will find some black filament is too brittle, that
added and mixed with some recycle and scrap after produced.
3.Productiong quality control
1)we have diameter laser device kits to control extruding rate on
line, when diameter smaller or higher than accept range, the laser
device kits will adjust the extruding rate higher or smaller to
make diameter range at acceptable.
2)keep each record filament samples sent to customers, build a
tracking able document.
3)when the filament put on shelf longer than half a year, please
dry the filament again.
