BOY �C About the machine

The extremely compact injection molding machine BOY 60 E with servo motor pump drive and a closing force of 600 kN is energy efficient, quiet, fast and precise. The fully-hydraulic injection molding machine meets the highest technical standards and uses resources extremely carefully. Due to the compact design and free overhanging two plate closing system, the machine is ideally suited for plastics processing.

Working with Baum��ller, an optimum motor-converter constellation was designed, which increases the machine��s performance significantly and and reduces the cycle times and then keeps them constant. Type DSD2-100, dynamic three-phase current servo motors with surface ventilation and a speed of 1,600 rpm are used. These are ideally suited for highly dynamic applications with maximum requirements for acceleration capacity and the best start-stop qualities, i.e. ideal for injection molding machines. Due to the field weakening, speeds of up to 2,500 rpm can be achieved. This in turn enables a smaller converter to be used. Thanks to the advanced line direct attachment, the installation space of the motor-pump combination can be reduced significantly by the omission of the pump support. Moreover, this in turn reduces noise emissions.

Due to the perfect interaction of motor, converter and control, the process and quality are constant, which is very important, especially in injection casting. The Baum��ller b maXX 5533 converters control the motors and the servo pump. With the help of the servo pump software V2, among other things, overshoots are minimized in the hold pressure area. This ensures a constant cycle time and thus for high-quality products.
