Injection Molding Machines and IML Robots

TWO PLATEN HYBRID TECHNOLOGY

Powerful • Efficient • Compact

The BIPOWER Series are two-platen clamp, hybrid power injection moulding machines available in 1300-, 1500-, 2000-, 2500-, 2700-, 3500-, 4200-, 5500- and 7000-tonne models. The injection unit features a reciprocating screw with electric screw rotation, with injection capacities (g PS) ranging from 2948 to 74900 (x1 injection unit 1300- to 7000-tonne models) and also 102060 to 149800 (x2 injection units on 7000-tonne model) across the line.
