FRIDAY N PE 2 018 M AY 11TH NPE2018 New Technology Focus Check out What's New in Pipe, Profile and Tubing Extrusion On display at Graham is an American Kuhne brand three- layer line for medical tubing. By Jim Callari Plascs Technology The conEX NG from Baenfeld-Cincinnaঞ (Booth W2771) is a conical twin-screw extruder for PVC pipe and profiles. The screw core fits all screw tempering systems, and the gearbox design allows several different motor posiঞons (U or Z ver- sion). Processors can also choose between different barrel tempering and dosing systems, allowing a wide range of out- puts to be covered with one machine. The machines can work with process pressures up to 520 bar (7500 psi), which are required when producing small or thin-walled profiles or when using regrind and recycled materials in coextrusion. Thanks to minimized residence ঞmes and quick cleaning, color changes can also be done much faster, which saves material, the com- pany says. braঞon basket, the QuickSwitch system, which has an effec- ঞve diameter range from 11.023 to 19.685 in. The system is of interest parঞcularly to processors that run large pipes, be- cause a diameter change is said to generate very lile waste. All process parameters can be set and stored in the all-in-one control system. KraussMaffei Berstorff's KM-VT 250/1/6 vacuum tank for pipe extrusion features integrated vacuum control and fre- quency-controlled pumps that are fully integrated into the C6 line control system. This is said to provide for energy savings and uniform product quality. Milacron (Booth W2703) is displaying its TC conical twin- screw extrusion system, which has a wide range of opঞons and customized screw designs matched specifically to the process requirements. Graham Engineering (Booth W2743) is displaying its Amer- ican Kuhne tri-layer medical tubing line, consisঞng of modular micro extruders and XC300 Navigator with integrated Twin- CAT Scope View high-speed data-acquisiঞon system. Guill Tooling & Engineering (Booth W4588) is showing the latest generaঞon of its Series 800 two- to six-layer extrusion tooling for tubing ODs from 1/8 to 6 in. Aimed at automoঞve, medical, appliance and industrial applicaঞons, the redesigned Series 800 is said to produce flawlessly smooth extrusion and layer definiঞon of tubes from fluoropolymers and other mate- rials for mulঞ-layer, mulঞ-lumen medical tubing, as well as fuel-line construcঞons, mulঞ-layer PEX pipe and drip-irriga- ঞon applicaঞons. Complete thermal insulaঞon of the barrel minimizes radia- ঞon losses, and by using reluctance or synchronous motors, the conEX NG offers reported energy savings of up to 20%. The conEX NG extruders are available in three sizes (42, 54 and 65 mm), with outputs from 80 to 550 lb/hr for pro- files, and 100 to 1000 lb/hr for pipe. KraussMaffei Berstorff (Booth W403) demonstrates its response to demands by processors for conical twin-screws that can be used both as main extruders and as part of a co- extrusion system. The KMD 73 K/P conical twin at the show reportedly offers just that—high outputs and pressure stability in a robust machine design. The opঞonal bimetallic barrel lin- ing paired with a tungsten-carbide welded screw—a require- ment of the North American market—also enables it to be used in pipe extrusion. Space-saving and customer-specific coextrusion models can also be installed in ঞght quarters for efficient producঞon. Downstream, the company is showcasing its flexible cali- WHAT IS THE MAIN CHALLENGE FACING THE PLASTICS INDUSTRY TODAY? "Circular Economy, in other words the claim to completely recycle used raw materials across the life cycle of a product in the producon process, is a topic that will increasingly influence the industry in the coming years. Our job will be to meet these requirements, both as a society and industrially, and to develop sustainable soluons and to avoid environmental polluon." — KARLHEINZ BOURDON, KraussMaffei, Plasঞcs Hall of Fame Class of 2018 BIG thing one 17
