Protections on the extruder
This extruder include three auto- alarming functions:
-Over-current prevention
-Temperature go up or down by big range in short time alarm
-melt pressure out of setting range alarm
All Earth wires are connected to a Bus bar- We need to have 3phase Neutral & Earth 415 V 50 HZ.
1.With flange, see the following picture, as buyer drawing
2.Need one more cooling fan, see the picture
3.No need the part of feeder, see the picture.
4.Need guard for barrel, see the picture
5.Hopper need lip, see the picture. The Inside of the Adaptor need to be Hard chromed – Looking like the Screw. Heating Element on the Gate should be only on the Extruder side.
6.As buyers Drawing of the adaptor
