K 2013: A peak inside the battenfeld-cincinnati open house

During October 17-21, about 400 visitors attended the battenfeld-cincinnati open house at its Kempen, Germany facility. Visitors saw live demonstrations of a PP sheet extrusion line, a coextrusion line producing a fiberglass-reinforced 4-layer PP-R pipe and a coextrusion line manufacturing a 3-layer PVC pipe.

In Kempen, the packaging division demonstrated an extrusion line for producing PP sheet with thicknesses ranging from 200 to 2,500 µm, which was equipped with a high-speed BC-75-40 DV T4 extruder and the new Multi-Touch roll stack.

Since the market launch 10 years ago, battenfeld-cincinnati has already installed more than 170 high-speed extruders worldwide. The compact 75 mm-machines reach outputs of up to 1,500 kg/h for PP and up to 2,000 kg/h for PS.

The company touts that a "special eye-catcher" was the Multi-Touch roll stack incorporated in the line, which operates with two large chill rolls instead of the conventional stack of three rolls, but with the addition of five post-cooling rolls. In this way, even cooling and calibration of the sheet is achieved on both sides. The outcome is reportedly premium-quality, virtually tension-free sheet with extremely narrow thickness tolerances.

Another product showcased was the 4-layer pipe extrusion line, where the infrastructure division presented extruders, dies and downstream equipment all the way to the cutting device.

Plasticizing of the melt within the line to produce a 500 mm pipe with a 36.8 mm wall thickness was handled jointly by a solEX 60-40 single-screw extruder (for the inner and outer PP-RCT layers), two uniEX 60-30 coextruders (for the middle layer made of fiberglass-reinforced PP-RCT), and a uniEX 35-30 (for the covering layer, also made of PP-RCT). A coEX 30-25 added the color stripes. All of these extruders operate with AC drives and optimized processing units, so that energy-efficient production is ensured.

The die on display was the new helix 630-4 VSI-T+ which, due to the EAC internal pipe cooling combined with a new, innovative "active melt cooling system," not only reduces the overall length of the line, but also ensures high product quality, since the sagging effect is significantly reduced. Thanks to this unique technology, pipes with even larger wall thicknesses can now be manufactured at reasonable cost as well.

Also at the open house, the construction division presented a line to produce PVC foam core pipes with an output of 1,000 kg/h. In addition to one model each from the twinEX counter-rotating parallel extruder series and the conEX range of counter-rotating conical extruders, the line on display was equipped with two further highlights: a spider 400-3 pipe die and the new RTA 250+ cutting device. A 160 mm pipe with an extremely low weight per meter was produced.

The advantages of the new pipe die are its high performance, optimal layer thickness distribution with narrow tolerances, and short dwell times thanks to short flow paths and the compact design of the die. Moreover, it offers flexibility, since it is able to process the entire bandwidth of different materials and can also be converted for 2-layer applications.

The RTA 250+ is flexible and able to cut both PVC and Polyolefin pipes with a wide range of diameters and wall thicknesses. No drive unit is required on the rotating cutting blade, so that the most stringent demands can be met with simultaneous maximum stability, according to the company. Due to the use of frequency-controlled carriage and rotation drives, the deceleration energy can be reclaimed as well and the efficiency thus increased even further.
