Injection Molding
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.

Greater Pickings in Robots for Injection Molders
The newest crop of robot automation for injection molding machines, displayed recently at the Platex show in Osaka, Japan, and the Plast-Ex Show in Mississauga, Ont., continue the trend toward six-axis jointed-arm models and improved servo-driven, beam-mounted units seen at last year's NPE show in Chicago. The latest introductions also include new controls for servo-driven robots, new units designed to work in palletizing cells, and a range of new sprue pickers in servo and pneumatic models.

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.
