E-Series injection moulding machine
E-Series injection moulding machine
The document discusses the BOY 55 E and BOY 90 E injection moulding machines, highlighting their advanced features such as the servo-motor pump drive. These machines are designed to be more economical, quieter, faster, and more precise compared to traditional models.
Key Features
- Servo-Motor Pump Drive: This innovation allows for significant energy savings by dynamically controlling volume and pressure through motor speed adjustments. The motor only operates when necessary, reducing energy consumption, noise, and hydraulic energy loss.
- Compact and Reliable Design: The machines are compact, easy to maintain, and have low operating costs. They are also designed for easy automation integration.
- Cost Efficiency: The machines offer a favorable price/performance ratio, low energy consumption, and reduced maintenance costs.
Technical Specifications
- BOY 55 E: Clamping force of 550 kN, maximum shot weight of 158.9 g, and screw diameters ranging from 18 to 42 mm.
- BOY 90 E: Clamping force of 900 kN, maximum shot weight of 252 g, and screw diameters ranging from 28 to 48 mm.
Performance and Efficiency
- The servo-motor pump drive reduces energy consumption by half compared to electronically controlled variable displacement pumps and is more efficient than electro-mechanical machines.
- Noise levels are reduced by up to 20% due to optimized motor speed and torque control.
- Improved precision and dynamics are achieved through precise motor-pump unit acceleration and deceleration, with a response time of 70 ms.
Practical Measurements
- Energy consumption is significantly lower with the servo-motor pump drive, especially in the production of LED housing using a 4-cavity mould.
- Consistency and repeatability are demonstrated with a maximum deviation of only 0.115% in moulded component weights.
Conclusion
The BOY injection moulding machines with servo-motor pump drive offer significant advantages in terms of energy efficiency, cost savings, and operational precision. They are suitable for various applications and provide a reliable and economical solution for modern manufacturing needs.

3 Method of operation A gear pump is driven by a special servo motor. Volume and pressure are controlled dynamically by adjusting the motor speed. This means that when neither oil nor pressure are needed, the motor switches off and no longer requires energy. Motor speed is always only as high as the respective cycle phase requires. At all times, the motor is thus performing in an optimum, energy-efficient way. In the pressure control phase (holding pressure), the motor speed is always as low as possible so that in this situation too, only the amount of energy needed to maintain pressure control...
