Compounding
In-Line Compounding of Long-Glass/PP Gains Strength in Automotive Molding
Another approach to long-fiber thermoplastic (LFT) molding is gaining credibility for producing a range of structural and semi-structural automotive parts. It is called direct LFT processing, and is already widely practiced in Europe.

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.
