BI-Power Injection Molding Machine

Available from NEGRI BOSSI S.p.A.

The Negri Bossi Bi-Power series of machinery is a line of large two platen hydro-mechanical equipment, with clamping sizes from 1050 to 6000 metric tons ( 1150 to 6600 US tons) and shot capacities from 104 oz. to over 2000 oz.

It is a very different design; the clamp is a two-platen clamping unit that greatly reduces the footprint of the machine with maximum flexibility of the mold-height and clamp stroke. The clamping force generation system is located on the moving platen that provides a symmetrical and uniform application of mold clamp forces and eliminates obstructions to the molding operations. The platen assembly movement is accomplished using two traversing cylinders that allow for rapid open and close speeds. The patented locking mechanism produces a clamp-up time is one of the best in the industry.

The Bi-Power series integrates an AC electric motor with digital speed control for screw rotation delivering torque and high performance with low energy consumption. All Bi-Power series machines are capable of three phases of simultaneous machine function (screw rotation, clamp opening/closing, ejection or cores) while maintaining full control of each movement.

The machine can be offered with many options, including automatic tie bar extraction, multiple valve gate control, multi-zone hot runner control and integrated Negri Bossi Flash Sy Cartesian robot. The standard control is the Columbia™. The Discovery™ touch screen fiber optic control is an option.
