SIG Corpoplast GmbH & Co. KG of Hamburg, Germany, has introduced a 64-cavity Premax injection molding system for PET preforms.
Previously, SIG offered molds with 48 and 96 cavities. The Premax64 also has been improved, with a new compact mold, a faster toggle unit and an integrated control system that overlaps motions of the robot and clamping unit.
A new “active” post-pressure module allows the press to build up the active pressure at 90 percent of cavity fill, instead of 100 percent. That means the post pressure already is built up during final filling, so there is no lost time for switching over. Also, the pitch distance of the cavities has been reduced, so the 64-cavity preform mold runs on a 353-ton injection press.
Separately, SIG Blowtec of Bonn, Germany, announced a processor in the Far East has blow molded a 7½-foot-long part used on a recreational vehicle, on a BlowTec 2-120/100 press. The complex ABS part has several molded-in inserts. SIG did not identify the molder.
SIG Corpoplast and Sig Blowtec are units of SIG Plastics International GmbH of Essen, Germany. The U.S. unit, SIG Plastics Technologies (USA) Inc., is based in North Branch, N.J.
