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.
