Flexible, Rugged Systems for Pipe, Profile

High-performance conical twin-screw extruder with calibration basket to change pipe diameter.

KraussMaffei Berstorff’s booth is highlighted by its flexible, high-performance KMD 73 K/P conical twin-screw extruder and its QuickSwitch calibration basket.

The KMD 73 K/P is said to offer very high output, robust machine quality and high pressure stability. These are properties that processors in window profile production—particularly for mass-produced goods—regard as crucial. The sophisticated process concept makes the series extremely process-reliable and simultaneously very flexible for using various formulations. The optionally available bimetallic barrel liner is paired with a tungsten carbide welded screw—a requirement of the North American market—to permit the machine to be used for pipe extrusion as well. Space-saving and customer-specific designed coextrusion models can also be installed in the smallest of spaces for efficient production.

The machine builder’s QuickSwitch calibration basket allows pipe processors to change the effective diameter range from 11.023 to 19.685 in. (280 to 500 mm). The system is particularly important when changing from larger to smaller dimensions because it minimizes waste during the transition. All process parameters can be set and stored in the higher-level, intelligent all-in-one control system and called up again at any time.

Further downstream, the KM-VT 250/1/6 vacuum tank integrates vacuum control and the frequency-controlled pumps. These, in turn, are fully linked to the C6 line control system for optimum start-up, energy savings and uniform product quality.

Conformal Cooling Technology Maximizes Cooling Efficiency

With so much happening in a busy show year between NPE2018, Amerimold 2018 and IMTS 2018, MoldMaking Technology is revisiting some of the technology that was on display. In case you missed it: DME says that its TruCool Conformal Cooling line provides greater overall cooling coverage with even distribution while maintaining a targeted, consistent temperature and reducing cycle times by as much as 60 percent.
