ExxonMobil unveils injection-grade PP
ExxonMobil Chemical Co. added a grade of polypropylene resin in January for precision injection molding of contact lens casting cups, lens packages, diagnostic cuvettes and other health-care applications.
Achieve 1654 resin, a nucleated metallocene PP, is made in Baytown, Texas, within the family of Exxpol metallocene-catalyzed products.
"We have been testing over six months with a handful of customers," said Corey Alemand, a senior technical sales representative in Buffalo Grove, Ill.
The firm designed and formulated the resin for dimensional accuracy and stability and ultra-low extractables.
ExxonMobil Chemical is a division of Exxon Mobil Corp. of Irving, Texas.
Mold-Masters buying its Brazilian agent
Mold-Masters Ltd. of Georgetown, Ontario, anticipates completing the acquisition of a Sao Paulo, Brazil, operation in February and focusing on that during the March 5-10 Brasilplast trade show.
Hot-runner provider Mold-Masters is acquiring its sales and service agency, Mold-Masters do Brasil Ltda., and adding manufacturing in Sao Paulo.
"We have a long-standing relationship with the agent down there," said spokesman Wayne Stoddard.
Separately, the firm officially opened its upgraded Singapore facility Jan. 17.
"Our local key accounts have had access to sales and service in those markets for years," Stoddard said. "It is going to the next level."
The Singapore site employs 10-12 and manufactures manifolds for the Southeast Asia market. Previously, Mold-Masters served the region from Georgetown or Kawasaki, Japan.
At the Plastec West show, Mold-Masters highlighted a new horizontal-hot-tip gating concept based on its Dura Centi-Shot and Dura Deci-Shot line of hot-runner systems.
Toshiba showcases 2 new press options
Toshiba Machine Co. America's plastics machinery division showed two new options in liquid injection molding of silicone on a 110-ton servo electric production model at its Plastec West booth.
"We are running a 2.4-gram part to show the customer the precision we can get out of electrical LIM," said Tony Codet, Toshiba area sales manager in Ontario, Calif. Toshiba molded a fingertip cover for manual money or paper counting to show the potential for small-part medical molding. The unit's shot capacity is 72 grams.
The new features involve laminar flow, which permits low-pressure processing, and shot-to-shot weight consistency.
Toshiba will offer LIM on electric presses with clamping forces from 20-390 tons, and for retrofitting earlier models. Codet said 60-80 percent of LIM output involves medical parts.
The EC110 unit that Toshiba displayed at the show will be showcased at Kipe Molds Inc.'s toolmaking facility in Placentia, Calif.
