Negri Bossi SpA showed two 210T injection molding machines at Fakuma in Friedrichshafen, Germany, with the SmartEnergy device for energy saving. Both presses have the new Smart Flex clamping unit that creates an oil free molding zone.

The first machine, an eCanbio press with 210 metric tons of clamping force, is molding a snorkeling glass in three materials: PBT, LSR and

LSR with azote. The press is molding the three materials simultaneously. The silicon injection, in the predosed cavities, is achieved by a cold runner mold characterised by N lines supplied by Guzzini. A Sytrama Robot removes the parts.

The other press at Fakuma, another 210-ton eCanbio, molds the gear part of bowling slopes in nylon. Negri Bossi officials said structural foam molding has several advantages, such as weight reduction, zero sink marks and dimension stability. The technique requires significantly lower mold pressure and processing temperatures.

Another energy-saving feature is Negri Bossi’s Smart Energy process.
