Product Descriptions
General Overview - Position of the BOY 80 Electric within the BOY Electric Series
The BOY 80 Electric is an advanced all-electric injection molding machine positioned in the mid-to-high tonnage segment of the BOY Electric series. With an 800 kN clamping force, it provides high process reliability for both technical part production and applications requiring larger molds.
The core engineering philosophy of the BOY Electric series is to combine fully electric drives for injection, dosing, and ejector axes with an energy-efficient and robust servo-hydraulic clamping system. This results in high dynamics, parallel motion capability, and outstanding repeatability.
Clamping Unit - 800 kN Two-Platen Cantilever System

Clamping unit technical data:
- Clamping force: 800 kN
- Tie-bar spacing (horizontal × vertical): 430 × 360 mm
- Maximum daylight between platens: 725 mm
- Maximum adjustable mold opening stroke: 475 mm
- Minimum mold height: 250 mm

These values ensure stable and homogeneous melt flow even at high filling speeds and with complex part geometries.
All-Electric Ejector System (E-Ejector)
The BOY 80 Electric uses a fully electric ejector system instead of a hydraulic ejector. This solution provides exceptional precision for both very slow and very fast ejector movements.
Advantages of the E-Ejector system:
- Digitally adjustable force, speed, and position
- Parallel ejector operation with mold movements
- Elimination of stick-slip effects
- Reduced mechanical load on mold and part
- Shorter overall cycle times
Servo Drives and Parallel Motion Capability
One of the key engineering strengths of the BOY 80 Electric is the ability to perform multiple machine movements in parallel within the same cycle.
Examples of parallel movements:
- Building clamping force during injection
- Ejector movement during mold opening
- Continuous dosing and decompression throughout the cycle
- Stepwise pressure build-up for precise filling
This architecture increases production speed while enhancing process stability.
Control System - Procan ALPHA 6
The BOY 80 Electric operates with the advanced Procan ALPHA 6 control system.
Control system capabilities:
- 9-stage injection speed control
- 9-stage injection pressure control
- 9-stage holding pressure control
- Holding pressure switchover based on pressure, stroke, or time
- Closed-loop injection and back-pressure control
- Production monitoring and part counting
- USB, Ethernet, and OPC interfaces
- EUROMAP 67 robot integration
