1.Produce process I . Before produce extruding filament ,we will dry ABS and PLA for a enough time (3-5 hours). II. Mix with colors masterbatch or colors powder, all which . III.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 I. 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. II.keep each record filament samples sent to customers, build a tracking able document. III.when the filament put on shelf longer than half a year, please dry the filament again. Information of the PVA, PA Nylon, PC ,and HIPS and ABS filaments, ABS filament process temperature is 230-260° C,melting point is 230° C PLA 3D printer filament is 210-235°C, melting point is 200°C PVA temperature for printer is 180°C-200°C.Melting point is 200°C. PA Nylon temperature for printer is 220°C-250°C.Melting point is 260°C PC temperature for printer is 230°C-250°CMelting point is 260°C. HIPS filaments temperature for printer is 160°C-220°C,Melting point is 230°C. 3d printer Filament Extruder: high speed extruders adopts notched barrel (with water forced cooling transportation zone), shielded screw with special mixing structure ensures the stability of high extruding and the plasticizing quality.
