A BOY 90 E, which is the largest model in the BOY product range with a clamping force of 900 kN, will be equipped with a second injection unit and will produce in one work process, safety glasses consisting of two different plastics. While the horizontally positioned injection unit on the BOY 90 E injects a super-transparent PP for the glasses and the frame, a vertically positioned injection unit will inject a colored PP for the sides of the glasses.

The injection unit for a second component based on the ultra compact BOY XS and is equipped with an own hydraulic drive and control. The machine offers a plasticizing volume of 8,0 cubic centimeter and achieves injection pressures up to 3.128 bar.

The controls of both machines communicate with each other via special interfaces and assure a fluent process of the injection moulding cycle. Due to the low required space of the BOY XS, the injection unit can be arranged in various positions on the basic machine. As a rule, the injection unit is placed vertically above the two-component mould, although a lateral installation is possible. The drive unit, which includes the control, is positioned on the backside of the machine. The open nozzle plasticizing unit is connected to the injection unit for the second component through a corresponding adjustable high-pressure hose line. This flexible machine arrangement enables countless application possibilities when considering two- component injection moulding.
