Torque & Speed How Much Is Enough?
You may be thinking of buying one of the new ‘high-torque/high-speed’ twin-screw compounders in order to raise your output without going to a larger machine. But how much torque or speed do you really need? Underusing a high-powered extruder wastes investment dollars. So look carefully at what is required for the materials you run.

New Compounding Options Strengthen Pull of Molded Magnets
Thermoplastic polymer-bonded magnets are exerting a stronger pull on designers of motors, valves, sensors, and other electronic devices used in cars, telecommunications devices, and large appliances. The attraction is strongest in applications demanding greater design freedom than is offered by conventional magnets sintered from 100% metal powder.

For the second straight NPE show, the focus in compounding is on twin-screw machines that deliver more speed and torque—thus more output—than ever before. No fewer than six suppliers of twin-screw compounders are showing such machines. There’s something to see in in-line systems as well. And there’s plenty of news in PVC mixers and pelletizing equipment, too.

Lots of new additive and color concentrates will be displayed at NPE 2000. There will also be new pigments, including some for laser marking. Several new processing aids and modifiers for thermoplastics and thermosets are slated to debut. Also look for new mold releases and a purging agent for optical disc resins. Interesting new fillers include a new electroconductive wollastonite and high-impact wollastonite grades for automotive applications.
