BOY 50 Electric

In addition to the proven and energy-saving servo-hydraulic machines of the established E series, our portfolio now also includes the BOY Electric series in the 350-800 kN clamping force range.

The BOY Electric therefore offers all the advantages of an all-electric injection moulding machine in terms of high dynamics and parallel movements. For example, the drives for injection, dosing and ejector on a BOY Electric are realised electromechanically.

The electromechanical universal injection unit has been redesigned and significantly enhanced for the BOY Electric series. The new type of dynamic pressure measurement is unique in the field of injection moulding machines and a patent has already been granted. The force transmitted to the screw is recorded at the injection mechanism by means of a force sensor and analysed in the machine control system.  

The electromechanical drive technology offers additional benefits in the form of precise position detection, dynamic movement sequences and shorter cycle times thanks to parallel clamping force build-up for injection.

The proven two-platen clamping unit with the oil and lubricant-free mould installation space is supplied by the established and energy-saving servo-hydraulics. Together with the pressure intensifier and differential pressure technology, hydraulic pressure is converted dynamically into the clamping platen movement and energy-efficiently into the clamping force. 

The new electromechanical ejector exceeds the dynamics of its hydraulic counterpart: thanks to its accurate position detection and very direct control, parallel, precise and highly dynamic movements can be realised in conjunction with clamping platen or handling movements. These not only save cycle time in individual cases, but also protect the product as well as the mould, gripper and machine. The electromechanical ejector also has a major advantage with extremely slow movements, as the stick-slip effects that can occur in the hydraulic system are avoided.

The BOY Electric series has also been given a new machine design, which is not only characterised by its new look. The drive and inverter technology is integrated in the smallest possible space and still allows for numerous expansion options. A new, compact and low-maintenance safety technology is now also finding its way into the BOY injection moulding machines. This OSSD (Output Signal Switching Device) technology enables very user-friendly monitoring at the highest safety level. By systematically integrating the high-performance technology into the BOY Electric, BOY remains true to its philosophy of minimising the footprint.
