New type Lab extruder for 3d printer filament
Application:

3D printer has been used by designers, engineers and scientists to produce the disposable mechanical products and model, and it is already widely used in health care, education, toys, building, automobile, electronics, and anime field.

 Feature:

 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.      

 

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.
