Product Descriptions
General Overview - Industrial Positioning of the BOY 80 E Platform
The BOY 80 E is Dr. BOY's injection molding machine with an 800 kN clamping force, developed specifically for applications requiring larger molds, higher shot volumes, and a wide processing window. Designed according to the BOY Injectioneering philosophy, this model combines high mechanical stability with a compact machine frame.
The BOY 80 E is a versatile production platform suitable for processing thermoplastics, elastomers, silicones including LSR, thermosets (duromers), as well as metal and ceramic injection molding feedstocks used in PIM technology.
Clamping Unit - 800 kN Four Tie-Bar, Two-Platen Cantilever Design
The BOY 80 E is equipped with a four tie-bar, two-platen clamping unit in a cantilever configuration. This design provides both high clamping force and excellent access to the mold area.

These values provide significant advantages for applications requiring high filling speeds and stable melt flow.
Servo-Hydraulic System and Energy Management
The BOY 80 E operates with a servo-motor-driven hydraulic pump system. Hydraulic power is generated only when required. In addition, Dr. BOY's patented pressure intensifier system maintains clamping force during injection and cooling phases without the need for an additional pressure-holding pump.
Energy and hydraulic system data:
- Installed drive power: 15 kW
- Total installed power: 22.7 kW at 400 V
- Hydraulic system pressure: 180 bar
- Oil tank capacity: 200 liters
- EUROMAP 6 dry cycle time: 2.1 s at 301 mm stroke
This configuration ensures low energy consumption and quiet operation within the 800 kN class.
EconPlast Technology - High Wear Resistance and Homogeneous Plasticizing
The BOY 80 E can optionally be equipped with the EconPlast plasticizing unit. This technology significantly extends screw and barrel service life while reducing energy consumption, especially when processing glass-fiber-reinforced and abrasive materials.
Key advantages of EconPlast technology:
- Reduced energy consumption
- More homogeneous melt structure
- Reduced material degradation
- Extended maintenance and service intervals
Control System - Procan ALPHA
The BOY 80 E is equipped with Dr. BOY's advanced Procan ALPHA control system.
Control system capabilities:
- 8-stage injection speed control
- 2-stage injection pressure control
- 8-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 functions
- USB, Ethernet, and OPC interfaces
- EUROMAP 67 robot interface
