ABS PLA 3D Printer Filament Extruder +/-0.03mm Tolerance PLC Auto Controling System

------Extrusion Line

------Install space:9.92m*1.02m*1.98m(length*width*height)

------Average output:8~15kg/h+/-10%,production speed 60-85m/min(DN1.75mm & DN3.0mm)

------Total Power:20KW

------Brief introduction

GSD-45 3D Filament Extruder Machine uses the “SIEMENS”PLC and PID control system, precise cooling water temperature control system, roundness laser measuring system and efficient loading winding system etc.. The program will automatically control the cooling water temperature and according to the data from the roundness laser, which will make sure that the roundness tolerance is less than 0.03mm.

------Outwards appearance requirement

Internal and external surface of rod/wire should be smooth and single color, should be uniform wall thickness,no manufacturing defect and air bubble, shrinkage, crack, non-uniformity etc.
