Project of the month May 2018:Extrusion line in customized design for the production of small technical profiles
Overall view ME 45/5x25D with a quick-change plasticizing unit
The task:
Extrusion line with a quick-change plasticizing unit, a calibration unit and a haul-off and cutting unit to manufacture profiles from various filled thermoplastic resins
The solution:
1.) Single-screw extruder ME 45/5x25D with exchangeable processing unit
 |
 |
| Controller mini ME Control /4 | Exchangeable processing unit |
 |
 |
| Cylinder flanging | Preheating device for exchangeable processing unit |
- Asynchronous motor 14 kW, water-cooled
- Speed up to 80 rpm
- Quick-change processing unit with one-piece bimetallic cylinder
- 2 screws for processing filled or fiber-reinforced plastics
- Controller mini ME Control/4 for the operation and monitoring of the main extruder, a coextruder and a haul-off unit ME 30/6.1
2.) Calibration unit ME 14/6.1
 |
 |
| Waterbath with guide rollers | Ring nozzle, hinged |
- 1 vacuum pump VN95-BluLine, frequency-controlled
- 1 manifold with10 vacuum and 10 water connections
- Manual longitudinal, lateral and height adjustment of the calibration table
- Drying station with hinged ring nozzle Ø30mm
3.) Haul-off ME 30/6.1
 |
 |
| Transition from haul-off to cutter | Mechanical gap limitation |
- Haul-off speed: 1,5 to 30,0 m/min
- Pulling force: max. 800N
- Drive: 2 AC motors, à 1,3 kW
- Contact length: 500mm
- Caterpillar clamping: pneumatic
- Haul-off belts with 6mm LINATEX coating
- Haul-off control with ME Control 20/4
- Mechanical gap limitation
4.) Cutter ME 50/6.R1
 |
 |
| Cutter in start-up position | Cutting bush mounting |
- Cutting unit directly flanged on the haul-off ME30/6.1
- AC servo-drive for cutting blades
- Profile clearance 30x20mm or Ø30mm
- Mounting for profile-specific cutting bushes
- Controller ME Control 20/4-R
