CHICAGO — LG International (America) Inc. of Engelwood Cliffs, N.J., joined the two-platen injection press parade at NPE 1997 in Chicago.
LG formerly used the name Lucky Goldstar, and Goldstar, but the South Korean-based parent company has changed its name to LG.
At NPE, LG showed its first two-platen injection press, available in one clamping-force size: 500 tons.
The press is called LGH 500 M. The first one ever built is on display at LG's booth.
Hee-Seok Park, team manager in charge of exports, said LG will add a second size, of 950 tons.
Two-platen machines are smaller than ones with three platens, but keeping the platens parallel is a technical challenge. LG engineers use software developed in-house, when they calibrate the clamps in the factory, to solve the problem, according to Kyung-Chung Kim, chief research engineer for LG Cable & Machinery Ltd., the company's Korean parent.
The two-platen PG has a hydromechanical clamp.
Kim said the machines were designed to run quieter.
