Extruder Series Aims to Boost Productivity
Direct drive groove feed extruder, TPE tubing line and competitively priced Super Blue system on display.
Davis-Standard is exhibiting its next generation direct-drive groove feed extruder along with its popular Thermatic and Super Blue extruders. These extruders exemplify processing versatility and performance, and are shown furnished with new feedscrew and control technology.
The 2.5 in. (65-mm) direct drive groove feed extruder features a Davis-Standard Helibar design with a grooved intake zone, helically grooved barrel, and new barrier-mixing feedscrew technology. This extruder and feedscrew combination offers increased processing flexibility due to higher regrind levels and improved pressure stability. It also enables processing of a wider range of polymers at lower internal pressure and with improved energy efficiency. The Helibar design is advantageous in terms of higher throughput, improved melt pressure build-up, lower melt temperatures, improved melt homogeneity, reduced barrel wear and a shorter residence time. Applications well-suited to this extruder include pipe, profile, sheet and blow molding processes.
