Battenfeld Extrusiontechnik is launching a new modular concept for a complete profile extrusion line at this year’s K Show. The winBEX consists of an almost completely pre-assembled downstream package of components, plus a choice of four twin-screw extruder models. As with the previously launched miniBEX modular system, larger, medium-performance winBEX lines are available at a very competitive price in extremely short delivery times. The lines can be quickly put into production, giving processors an added benefit.

Depending on their specific requirements, customers can choose between the large, negative flight conical BEX 2-72 C twin-screw extruder with a performance range of 40 to 250 kg/hr, or three types of parallel extruder models with a wide working range of outputs, up to 500 kg/hr.

The downstream package includes a calibration unit, a haul-off and a cutting device. The calibration table consists of a 5.5 m frame with a water tank, four vacuum pumps and an integrated control cabinet. The control cabinet can be extended with additional 2 m or 5.5 m segments to reach the total length desired by the customer. Besides the electrical installations to control haul-off, the control cabinet also contains the control system for the cutting device with cut-length gauging and a vacuum chip extraction unit. The cutting device can either be a saw or a set of pre-heated knives.

The company is also showcasing new extrusion equipment for polyolefin pipe production. The BEX 1-90-30 D single screw extruder combined with a PO 250/900 VSI lattice basket die is a single screw extruder system that provides processors a significant increase in throughput without changing the screw diameter. The extruder’s output is boosted by more powerful motors and drives with higher torques. In combination with new barrier screw geometries, which ensure homogeneous melt at low temperatures, an average increase of 25% in throughput can be achieved.
