Promise for Better Chips
A new quick-drying polymer is generating excitement as much for its future promise in semiconductor manufacturing as for its current cost and efficiency savings. Polyset epoxy siloxane requires less curing heat and has a lower water uptake rate than standard redistribution layers on silicon wafers. EurekAlert! says to expect future use in chip packaging and micro/nano imprint lithography.

Conductive Polymer
Defying basic assumptions, plastic may conduct electricity. That's what one company reports about its ElectriPlast™ polymer, which may be molded with metal fibers encased in plastic. As a potential metal replacement, and now with a manufacturer secured, conductive plastic may play a role in forming antennas for electronic devices.

Shopping for In-Mold Labeling
Bring a checklist in the hunt for a new IML press. A machine capable of thin-wall packaging, Injection Molding Magazine says, requires a close look at consistent and repeatable injection, robust clamping, and high plasticating rates. The answer for effective IML presses just may come from longer screws and barrier screws.

A Rubber Riddle Solved
How did rubber thermoset halve its cycle times? By injecting the hottest material in the center of a mold, according to Modern Plastics Worldwide. The article refers to the Melt Flipper, a tool that heats a compound without extending the filler material's maximum temperature. It also offers consistent flow and temperatures in the mold.

Warpage Control
Water tanks, spray-cooling tanks, and air racks—all viable cooling options to prevent plastic warpage. And each, in its own way, avoids interfering with processing speed. For some molds where thickness or unique profiles are factors, however, accurate cooling precedes speed. Plastics Technology distinguishes between the need for speed and the need for slow heat transfer.

Smoothing the Rough Edges
Fused-deposition modeling has the unfortunate characteristic of rough finishes despite its reputation for strength, Machine Design writes. To cover these blemishes, a two-step smoothing process adjusts the chemical reaction, adding a uniform finish and watertight seal. And it does so without interfering with the design and properties.

Rapid Manufacturing Comes of Age
A motorsport developer pioneered new design ground in transforming rapid prototyping into rapid manufacturing, reducing time and part volume in the process. Using Selective Laser Sintering, the company made 3D engine reed valve components from 2D layers. Composite sinterable powders added the strength needed to create the finished parts.

Simplified 3D Scanning
New software trumps old-fashioned sprays in removing noise from 3D reflective parts. Keeping the input data points intact, the software finds and removes data points associated with reflection. A time saver, the scanning data software contributes to reverse engineering, identification, and quality assurance.

Curbing Wrap Rage
Here's a Christmas morning turned sour: Dolls left boxed up. A teen's new iPod® untouched. And parents and children equally frustrated. It's called "wrap rage" and it's a common post-holiday syndrome. Aggressive packaging may protect a product from damage, but may also deter its owner from using it. Here's what a post on The Plastics Exchange says the industry is doing to deter packaging woes.
