Past Issues


Winders: They're Pushing New Limits In Speed and Tension Control
New-generation winders for blown and cast film are winding bigger, better rolls at higher speeds and lower tension. They've gotten so fast that cast film lines can now realize their full productive potential.

Benchmarks for Productivity
I like playing with statistics, and there’s no richer trove of new statistics about plastics than the SPI study, The Definition, Size and Impact of the U.S.


Economic Update: The Falling Dollar: Short-Term Gain, Long-Term Pain
It is by now no secret that the U.S. dollar has declined in recent months.

Close-Up on Technology

Welder Is Super-Rigid For Extra Precision
Model 2050 is a 20-kHz ultrasonic welder designed to minimize deflection for precise joining of sensitive parts.

New Polymer Uses Sunlight To Arm Itself Against UVDamage
 Using sunlight to protect against sunlight—that’s the unusual concept behind GE Plastics’ new Lexan SLX polymer.

Composites Show Introduces Reinforcements, Fillers and Additives
Pultrusion, filament winding, SMC, BMC, polymer concrete, and advanced composites are targets for new reinforcing fibers, fabrics, fillers, and other additives introduced at the recent Composites 2003 Show in Anaheim, Calif.

What to Do When the Mold Just Won't Fill Right
What should have been a routine injection molding job was plagued with problems right from the start.

How to Optimize Adhesion in Hard-Soft Overmolding
 Over the past decade, soft-touch overmolding has radically changed the look, feel, and function of a broad range of consumer products.

How to Thermoform Top-Quality IMD Inserts
Wider adoption of in-mold decorating (IMD) for demanding industries like automotive, appliances, and consumer electronics will require thermoformers to have the right know-how and equipment.

TP Composites: New Option in Lightweight PP/Glass Composites
From its Detroit-area offices, Swiss-based Quadrant Plastics Composites (QPC) has introduced a family of lightweight reinforced thermoplastic (LWRT) composites to North America.

Processor's Edge

Pushing the Limits Of Structural-Web Molding
Four years of development and over $7.5 million have resulted in what is believed to be the largest part ever made by gas-assist injection molding and also the largest ever made by the structural-web process, a variant of gas assist.


Injection Molding Troubleshooter: Get the Most from Flow Simulation
Flow-simulation software is one of the most powerful tools ever developed for improving injection molded part quality.
