extruder ProgrammeSingle screw extruder - Screw diameter from 25mm to 250mm- Barrel length from 24D to 45D with venting and without- High Speed Extruder 60mm and 72mm screw diameter, speed up to 1.500rpm- 3 zone screws, venting screws, barrier screws with shear and mixing elements- Barrierscrewsfortheproductionofpolyolefin’s without screw changing- Removal of the screw either to the rear or to the front- More than 60 years of experience in screw design- Single, double or four-fold venting (hygroscopic polymers)- Drive systems water-cooled in asynchronous, synchronous and torque motor design with highestefficiency
Twin screw extruder - Screw diameter from 27mm to 180mm- Enhanced free volume of OD/ID of 1.66- Uniquely high torque by means of a new hub-shaft connection - Up to 30% improved cooling capacity by optimized flowofthecoolingagentthroughthebarrel- Highest available torque density for co-rotating twin screws (15.0 Nm/cm3)- Screw in modular principle design- Barrel in modular principle design- Drive systems water-cooled in asynchronous and synchronousmotordesignwithhighestefficiency
Complete lines for the production of mono – or Coextrusion films and sheets up to 11 layersMaterials - PS, SB, HIPS, ABS- PP- A-PET, C-PET, G-PET- PE-HD, PE-LD, PE-MD- PA, EVOH- PC, TPU, TPE, PMMA- Biopolymers - High temperature resistance materials
Modular principle - Pre-drying (dry air, IRD)- Dosing systems (volumetric, continuous gravimetric or batch systems)- Extruder (Single screw, Twin screw)- Screen changer- Melt pump- Static mixer- Feed Block (up to 11 layers) - Die (automatic die)- Roll Stack (vertical, horizontal, inclined)- Laminating and coating systems- Thickness measurement and surface inspection systems- Surface treatment systems (corona) - Longitudinal cutting systems with knife, saw, milling - Edge trim handling- Post-treatment like surface cleaning/ protectionfilm- Take-off units- Cross cutting systems like guillotine, saw, milling- Semi- and automatic winding systems- Handling – Robot systems for sheet stacking- Data management KEC
1995 introductionofthefirstflatfilmline for the production of drainage membranes for the building and construction industries out of PE-HD and PP in a width of 3.3 m
1998 development of the firstFeedBlock “lamellatype”for up to 8 layers
1997 developmentofthefirstK180extruderin33D length for the production of PE-HD
high performance bubble coolingsmart lip maximizerThe increase of profitability of our high performance lines – that was the starting point for our R&D de-partment when they developed the MAXIMIZER, an optimally adjusted product range for outer bubble cooling. The development team consisting of R&D engineers, designers and sales people was able not only to increase the output capacity of the lines by up to 50% but also to positively influence the quality of the films.
Smart Lip Maximizer LN – Efficient cooling concept for “long neck” production for HDPE and LDPE films.
Smart Lip Maximizer – Infinitely variable height adjustable cooling ring for improvement of output and film quality.
Smart Lip DUAL – Variable dual cooling ring in stack design, infinitely variable height adjustment for impro-vement of the throughput capacity and film strength.
KEC Kuhne Extrusion Control – Operator friendly, clear and central automation controls the production and assures a continuous high film quality.
Kuhne Smart Change – Automatic format change at the push of a button.
Kuhne’s modular principle offers the following options:Extruders
With smooth or grooved feed sections in diameters from 25 to 150 mm
Die heads
- Mono die heads with diameters from 50 mm to 600 mm
- 3 layer die heads with diameters from 100 mm to 900 mm
- 5, 7,9 and 11 layer die heads with diameters from 150 mm to 750 mm
Quenching systems
High efficiency IBC and Cooling rings in different designs
Film take off units
- Reversing take off units with air supported turning bars from 1000 to 3600 mm
- Stationary take off units for a working width from 1000 to 3600 mm
Film winders
- Contact/centre/gap winder with one or two winding positions for a layflat width between 1000 mm and 3600 mm
- Contact winders with one or two winding positions for a layflat width between 1000 and 3600 mm
For the film winders we offer winding shafts and roll handling systems up to fully automatic solutions.
