PLA/ABS 3D printer filament

Production Control
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 .certified with ROHS.
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
IV we put all filament spool in shelf, different kind in different shelf, all categories arranged orderly.
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.
We haven't produced with scrap outlet, rework&recycle material, or dispose, but for quality assurance purpose.
3.packaging
We put each filament /spool on seal PE bag with desiccant , then smaller carton, then out big box
We also have vacuum heated bag to replace of PE bag, make better avoid moisture.

4.Productiong quality control

I. we have diameter laser detect kits to control extruding rate on line, when diameter smaller or higher than accept range, the laser detect 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, we will dry the filament again.

Our PLA filament advantages compare to other ABS filament:

We select of premier grade ABS material, low water absorption, high toughness. Factory direct sales, inexpensive, buy more, bigger discount!
