Close-Up on Technology

Cast Prototypes of Reinforced Nylon 6 Match Injection Molded Quality
A newly developed reactive casting process makes glass-reinforced nylon 6 prototypes and production parts quickly and easily from low-cost molds.

Metal-Powder Injection Molding Moves Into Larger Parts
It’s not just for small parts anymore: One of the latest developments in metal-powder injection molding (MIM) is its first commercial large part—a 3.5-lb flow-body housing for a passenger jet plane.

Purified Cellulose Fibers Show Promise In Reinforced Thermoplastics
Purified cellulose fibers could be the next lightweight reinforcements for thermoplastics.

Stretching Film's Limits
In the hyper-competitive stretch-film market, more layers often mean more market share. Moving from five layers to seven or nine can give an edge through higher performance or reduced cost.

Super-Clear PP Barrier Bottles Are Now Stretch-Blow Molded
In a first for stretch-blow molding, Chicago-based Pechiney Plastic Packaging, Inc. (PPPI) is launching a family of polypropylene barrier food containers that are claimed to be as clear as multi-layer PET bottles.

Starting Up

Success in LSR Molding
Liquid silicone rubber parts are getting larger, but most LSR molders still have relatively small injection machines with limited shot capacity.

Your Business in Brief - February 2003
BASF Buys Honeywell’s Engineering PlasticsBASF in Germany has agreed to purchase the engineering plastics business of Honeywell International, Morris Township, N.J.

Your Business Outlook - February 2003
Some injection molding companies expect the furniture market to awaken from its slumber in 2003, but others think it may take another year.


Chemical Purging: When and How to Do It Right
Extrusion blow molders are sometimes skeptical of chemical purging compounds (CPCs), and they have a point.

How to Buy Universal Testing Machines
More processors today are buyingso-called ‘universal’ testers to measure tensile, flexural, compressive, and shear properties for materials evaluation, application development, and quality control. Advanced electronics have improved these instruments’ performance and ease of use—and even led to lower prices.

On the Mend
New data for 2001 from the Bureau of Labor Statistics indicate that plastics processing is still more hazardous than the average U.S. manufacturing job, though it is getting better.
