Battenfeld-cincinnati USA (McPherson, KS) will feature its solEX NG and conEX NG extruder series with Industry 4.0–compatible BCtouch UX control for the first time in the United States at NPE2018.
The conEX NG has a flexible design with one basic machine model for both pipe and profile production, said the company. The extruder’s screw core fits all screw tempering systems and the gear box design allows several different motor positions. Processors can also choose between different barrel tempering and dosing systems. Thus, a wide range of outputs can be covered with one machine.

Gentle plastification is ensured and the machines can work with process pressures up to 520 bar (7,500 psi), which are required when producing small or thin-walled profiles, or when using regrind and recycled materials in co-extrusion. Thanks to minimized residence times and quick cleaning, color changes can performed rapidly, saving material.
The single-screw solEX NG extruder has a completely redesigned screw feed section with a significantly lower pressure profile, said battenfeld-cincinnati. This ensures high specific outputs, fast process start-ups at low screw torques and no conveying instabilities, even at high back pressures up to 500 bar (7,200 psi). Thanks to the new processing unit, a reduction of melt temperature by approximately 15 to 20°F is possible.
Therefore, the cooling length can be shortened as cooling baths need to remove less heat. Alternatively, for nearly all products, it is possible to increase line speed with the same cooling length, resulting in up to 20% higher outputs. Lower melt temperatures at a consistently high level of melt homogeneity also result in better product quality. For example, sagging is reduced, which is particularly important for thick-walled or large-diameter pipes.
Pipe producers operate under high cost pressure, which makes energy and material savings crucial for efficient production, notes the company. The solEX NG series needs up to 15% less energy, because it operates with less drive power and lower energy losses. Thanks to the grooved barrel and corresponding lower pressure profile, energy savings can be achieved by reduced barrel cooling. The machines’ processing characteristics, combined with special wear protection solutions for the processing unit, result in material and maintenance cost savings.
Battenfeld-cincinnati will exhibit at booth W2771. NPE2018 comes to Orlando, FL, on May 7 to 11.
