Our very first machine model, the BOY 15, featured our innovative two-platen clamping system.
Piston rods with three bearings pull the moving platen towards the fixed platen where the clamping cylinders are integrated. This design allows for a cantilevered clamping unit and when compared to conventional three-platen systems, offers great floor space advantages. By a decentralized, symmetrical application of the load, the tiebars, which also serve as piston rods, achieve full and even use of the clamping force even for moulds with asymmetrical inserts. The distances between tie bars and platens, which are very generous for this clamping force range, enable a flexible production even with very large and complex standard moulds. The clamping system developed by BOY features very few moving parts. This reduces costs not only for the investment, but also regarding machine maintenance.
Furthermore, this minimizes wear and, consequently, time needed for maintenance as well as downtimes. BOY's clamping system enables fast and flexible adaptation to all requirements. Easy access, short operating cycles, and quick retrofitment guarantee highest efficiency when using BOY injection moulding machines.
BOY: Continous optimimization for innovative injection moulding technique
During 50 years, nearly 50.000 injection moulding machines up to 1.250 kN were sold worldwide. BOY injection moulding machines require less space compared to other competitive models due to their compact design. Furthermore, the freely accessible two platen locking system enables the flexible use of moulds and offers many possibilities for automation and integration of BOY machines into production lines.
Access to all machine components is easy. Set-up times are correspondingly short and the maintenance of BOY injection moulding machines is uncomplicated. The Procan ALPHA control enables an intuitive machine operation with touch-screen operation, graphic menu navigation, and fast screen start-up. With the new servo pump drive, BOY machines require 50 % less energy, cooling power is also minimal and the noise level during production is considerably quieter. These and other advantages demonstrate that BOY stands for economy, efficiency, innovation and "Made in Germany" quality.
