American Aerostar plans mold-changer
American Aerostar Corp. of Valencia, Calif., is developing a quick-mold-change system for blow molding machines, initially for a customer in Mexico.
"It takes approximately two hours to make a mold change now," said Paul Sloane, vice president of marketing. "We are anticipating doing it in 15-20 minutes with hydraulic clamping and rollers and a special lift that carries the molds."
By May, Sloane expects a solution that would become available to the lead customer and others. "We have a drawing, and they are in the process of approving it now," Sloane said.
Kenrich developing anti-static additive
Kenrich Petrochemicals Inc. of Bayonne, N.J., has developed another high-performance antistatic additive.
The Ken-Stat zirconate anti-stat became available in early 2001 and is undergoing final Environmental Protection Agency reviews, said Eric Monte, Kenrich vice president of technology.
A processor can add a liquid or powder form of the material directly into the polymer during compounding to form a transparent, nonblooming, organometallic, electronic-transfer circuit. The material provides an anti-static effect that works independently of atmospheric moisture.
