The Negri Bossi Janus series of machinery is a hybrid drive configuration, with clamping sizes from 130 to 800 metric tons (150 to 880 US tons) and with shot capacities from 6 to 230 oz.
The standard Janus series incorporates a very unique motion control system; the system integrates a variable volume piston smart-pump that handles the injection, ejection and carriage movements, with direct mount drive servo electric actuators for mold clamping and screw rotation. The hydraulic injection axis allows high demand technical molding that would otherwise be difficult on an all-electric machine. The ejector and carriage hydraulic functions allow higher forces than an equivalent all-electric machine.
The Janus series integrates an AC electric motor with digital speed control for screw rotation, delivering torque and high performance, which mean that it is very energy efficient with consumption similar to an all-electric machine. All Janus Series machines are capable of full simultaneous control of clamp, screw and ejector/core operations with precise and independent control of each. The standard control is the Columbia™.

 AVAILABILTY
Standard sizes of Janus machines are typically in inventory at our Delaware or Iowa warehouses. Non-standard configurations are usually 12-16 weeks.
 VALUE
The Janus is a true hybrid and offers all that is good about an all-electric machine, along with hydraulic functions where higher forces and durability are demanded by the process. When compared to the all-electric it is a competitively priced machine. Excellent specifications, with many standard features that are often at extra cost on other brands.
 MAINTENANCE
Designed with the user in mind, the Janus is a machine that offers outstanding ‘up-time’ and reliability. To support our product, Negri Bossi offers an excellent spare parts and labor warranty package.
