Negri Bossi SpA's K 2007 booth turned out helmets and colorful chairs, and featured integrated production lines for molding and vacuum metalizing parts.
The Milan, Italy-based injection press maker introduced a new, smaller size of its Bi-Power press, with a clamping force of 1,200 metric tons, at the Dusseldorf show, held Oct. 24-31.
The two-platen VH1200 molded chairs from talc-filled polypropylene. The parts were removed by a six-axis Gaiotto robot from Negri Bossi's automation unit, which moved the chair to a trimming and degating station.
Bi-Power presses come with electric drive as standard. The lines goes from 1,200 tonnes all the way up to 6,000 tonnes.
Negri Bossi ran three all-electric injection molding machines at the K show.
A 480-tonne Canbel press molded white polycarbonate helmets, with in-line quality control.
For the vacuum metalizing application, a 210-tonne Canbel molded a parabolic reflector for a front light of a car. A six-axis Kuka robot loaded the parts into the metalizing chamber.
A 70-tonne, all-electric Argopan press molded PC sunglass lenses, then a Kuka robot moved them to an automated dip coating, a flash-off station and a curing station. A vision system from Negri Bossi's parent company, Sacmi Imola scrl, checked each lens.
A sister company, Oima SpA, ran a water-assisted, injection molded part: a complex automotive cooling pipe. Another Oima press led off an automated cell for making swim goggles, by molding both the PC lenses and the frame and straps made of liquid silicone rubber - all inside the same mold, mounted on a rotating table. Negri Bossi's U.S. operation is based in Newark, Del.
