GI Plastek molding PU parts for Chiron
GI Plastek is reaction injection molding 29 parts made from polyurethane structural foam for Chiron Diagnostics Corp.'s ACS:Centaur automated immunodiagnostic system.
GI Plastek's Newburyport, Mass., plant is making the parts, including the top cover, reagent box and enclosure panels. The parts are as large as 48 inches long by 14 inches wide and weigh as much as 25 pounds.
Chiron of East Walpole, Mass., develops systems that process and analyze medical laboratory samples associated with thyroid, reproductive, anemia, oncology and infectious disease testing.
GI Plastek also has injection and gas-assist molding plants in Marysville and Bellville, Ohio.
Industrial Custom adds machines, staff
Earlier this month, Industrial Custom Products of Minneapolis added a 7-foot-by-11-foot rotational molding machine and a five-axis computer numerically controlled trimmer to make exterior parts for trucks.
The parts are made from ABS and polyethylene. About six employees were added to the staff of more than 200. The firm operates plants in Elkhart, Ind., and Syracuse, N.Y.
The company also thermoforms parts for original equipment manufacturers in the automotive, dunnage and gear industries.
Nalge Nunc replaces acetal with Carilon
Nalge Nunc International, one of the world's largest suppliers of laboratory products, turned to Carilon aliphatic polyketone as a replacement for acetal in its Unwire Test Tube racks.
Houston-based Shell Chemical Co. featured the application at its design show booth.
The injection molding grade of Carilon is resistant to hydrolysis and easy to process on conventional presses, according to the firms. Other benefits are a lower specific gravity than acetal, decreasing the amount of material needed; a reduced production setup time and a change in the injection molding pressure, resulting in increased capacity and decreased production cost; no odors emitted during processing; and a receptiveness to general- purpose colorants.
When Shell's Geismar, La., plant begins production, the company will have an annual Carilon capacity of 55 million pounds. Shell could add a reactor to double the capacity if needed, said Michelle Londa, Carilon Polymers' marketing manager for the Americas. Shell also is working with a Japanese affiliate to market the material overseas.
