This system inserts fittings, nuts, pins, chassis and other works into molds during plastic injection molding. It can be retrofitted on both vertical and horizontal injection molding machines and configured in any form from simple robotic hands to full systems according to needs. Moreover, turnkey solutions from feeding to extraction can be built by coupling with an unloader from STAR SEIKI. This system is helping to expand insert injection molding for connector terminals, intake manifolds, cell phones and computer casings, and more.
