Promotion helps get water to Third World
A sales promotion by a plastic water tank manufacturer and the body that represents Australia's plastics industry will help deliver clean water to people in Third World countries.
Linpac Rotational Mouldings Pty. Ltd. of Melbourne, Australia, and the Melbourne-based Plastics and Chemicals Industries Association launched the Tankaid project in January.
PACIA Chief Executive Michael Catchpole said the project involved a discount offer to PACIA members that encouraged them to buy a Linpac tank, with 5 percent of the price going to the WaterAid Australia charity.
Melbourne-based WaterAid operates in 17 countries in Africa, Asia and throughout the Pacific region to provide disadvantaged communities with clean water, sanitation systems and hygiene education.
Linpac General Manager Chris Phillips said more than 30 tanks were sold through the promotion when it closed at the end of March. WaterAid will receive a US$4,110 donation from the groups.
Linpac Rotational Mouldings, part of Linpac Group Ltd. of Birmingham, England, manufactures linear low density polyethylene tanks, using food-grade pigments in sizes from 156 gallons for domestic use to 11,700 gallons for farms. It operates plants across Australia.

Shin-Etsu introduces new liquid silicones
Shin-Etsu Silicones of America Inc. has introduced new liquid silicones for silicone-to-plastic injection molding.
The Akron, Ohio, firm said its KE2090 and KE2095 series Select-Hesive liquid injection molding systems provide primerless adhesion to a variety of thermoplastics. While they stick to the plastic substrate, they don't adhere to metal surfaces of the mold. Suited for over-molding and coinjection, the silicones cure quickly and firmly to the plastic without any need to pretreat the plastic.
Each new silicone for liquid molding holds its bond to plastic under temperature and humidity extremes, according to Shin-Etsu. The products differ in their affinity to plastics. KE2090 sticks best to polycarbonate, polybutylene terephthalate and polyphenylene oxide, while KE2095 shows more affinity to nylons and polyphthalamide. They are available in hardnesses of 30-70 Shore A.

D-M-E claims insert is industry's smallest
D-M-E Co. of Madison Heights, Mich., has introduced what it calls the industry's smallest indexable mold dating insert - measuring 4 millimeters in diameter.
The snap-in-place insert is designed to mark dates on small electronics, such as cell phone cases, medical parts and on standing rib lines.
Also new from D-M-E: a dual-ring mold dating insert that the company said reduces complexity and cuts time. It measures 10mm in diameter and 12mm high.
Firms' dual process cuts molding time
Erwin Quarder Group of Espelkamp, Germany, is linking its tandem injection molding technology with the MuCell process from Trexel GmbH of Wiehl, Germany, which is a unit of Woburn, Mass.-based Trexel Inc.
Quarder introduced the combination during an open house in March. Using both technologies can cut cycle time by 50 percent over traditional injection molding cycles, the company said.
The tandem technology uses an alternate sequence for cooling time during molding. A tandem mold works like a stack mold, except that the locking faces open in alternating sequence, instead of simultaneously. While the cooling time runs in one parting line, a second parting line already has been injected.
Quarder said the two parting lines allow for running products that are different or the same in form and weight - for example, left- and right-hand auto parts.
Erwin Quarder Werkzeugtechnik makes tandem molds. Erwin Quarder Automation Technology makes part-removal systems for tandem molds and other automation products.
Trexel's MuCell process uses microcellular foam gas in its supercritical state to create a foamed part.
