CHICAGO (July 15, 11:30 a.m. EDT) — Presma Corp. displayed some exotic products made by structural foam molding, at its NPE booth, including a very heavy base to hold construction signs on a highway.
President Romano Discacciati said Presma supplies special machines to a German molder, which blends old ground-up cables, metal and all. A twin-screw extruder feeds a piston injection system.
“We are using a twin-screw machine, which is very unusual in injection molding,” he said at Presma's NPE 2003 booth.
Presma of East Brunswick, N.J., was introducing the sign-holder application to the U.S. market at NPE.
Presma also displayed a side-gusseted, square-bottom plastic bag with integrated tubular handles at its booth. The company's sister company, Plastimac, developed a machine that automatically inserts the handles into the bag. Discacciati said U.S. bag makers can use the technology to compete against T-shirt bags coming from China.
