Toshiba Machine Co. America introduced the ECNII injection press, the next generation of its all-electric machines — plus a new Injectivisor V30 controller.
The Elk Grove Village, Ill.-based company said the ECNII keeps the core technologies of its existing EC and ECN presses, with improvements such as a new, low-inertia injection mechanism and a high-torque motor.
ECNII presses also use high-speed mold opening and closing and part ejection, with improved mold protection.
Toshiba is offering the ECNII in clamping forces from 20-950 tons.
Features of the Injectivisor V30 include one-screen setup of processing data, an extended internal 300-slot mold memory, the use of commercially available storage media thanks to standard USB and compact flash ports, and remote control of auxiliary equipment.
At NPE 2006, held June 19-23 in Chicago, Toshiba showed five ENCII presses. One press demonstrated a micropattern imprint on a 0.4-millimeter, thin-wall polycarbonate part. The press improved the imprint factor, thanks to its optional high-speed injection unit, which has an injection speed of 550mm per second.
Another ENCII molded a 0.4mm thin-wall polycarbonate light guide for cell phones.
A two-machine work cell molded a golf-turf-repair tool, by overmolding a liquid silicone rubber grip over a plastic substrate of polybutylene terephthalate.
A fifth new all-electric molded polypropylene coasters, in a four-cavity mold, with a cycle time of less than 5.5 seconds.
Toshiba also demonstrated its real-time monitoring system, the iPaqet.
