Dr. BOY Injection Technology and the Positioning of the XS V Model
Dr. BOY is a German manufacturer specializing in small and medium-tonnage injection molding machines, with a strong focus on high-precision and high value-added applications. Instead of downsizing large machines, Dr. BOY develops application-specific machine architectures for both vertical and horizontal injection molding technologies.
The BOY XS V model is based on the proven BOY XS platform and features a vertical arrangement of the injection and clamping units. This configuration is specifically designed for applications where metal, glass, or plastic inserts must be positioned accurately within the mold.
BOY XS V - Ultra-Compact Vertical Machine Architecture
Thanks to its vertical injection principle, the BOY XS V allows inserts to be positioned and stabilized by gravity. The most distinctive feature of the machine is its fixed lower platen, which provides significant process advantages:
Prevents insert displacement during mold closing
Increases overall process reliability
Simplifies both manual and automated insert placement
The external dimensions of the BOY XS V are approximately 1100 × 580 × 2160 mm, resulting in an extremely small footprint of only 0.64 m². This makes the BOY XS V one of the most compact vertical insert injection molding machines in its class.
Despite its compact size, the machine has a net weight of approximately 457 kg, ensuring industrial robustness and excellent mechanical stability.
Clamping Unit - Fixed Lower Platen and Tie-Bar-Less Design
The clamping unit of the BOY XS V is designed with two diagonally positioned columns, creating a tie-bar-less working area. This configuration provides:
Open access to the mold area from three sides
The ability to use relatively large molds within a compact machine footprint
Ample free space for insert placement and automation systems
Clamping unit technical data:
Clamping force: 100 kN
Column spacing: 160 mm (diagonal 205 mm)
Maximum daylight opening: 250 mm (optional 200 mm)
Adjustable maximum mold opening stroke: 150 mm
Minimum mold height: 100 mm (optional 50 mm)
Maximum mold weight on moving platen: 22 kg
Mold opening force: 15 kN
Mold closing force: 10 kN
These values provide an ideal mechanical balance for micro and insert molding applications.

8 mm
12 mm
14 mm
16 mm
Theoretical maximum stroke volumes:
8 mm: 1.0 cm³
12 mm: 4.5 cm³
14 mm: 6.1 cm³
16 mm: 8.0 cm³
Theoretical maximum shot weights (PS):
8 mm: 1.14 g
12 mm: 4.1 g
14 mm: 5.6 g
16 mm: 7.3 g
Maximum specific injection pressures:
8 mm: 2534 bar
12 mm: 3128 bar
14 mm: 2298 bar
16 mm: 1760 bar
These high pressure values ensure complete and stable filling of micro geometries and complex insert molds.
Screw Geometry and Plasticizing Dynamics
Screw L/D ratios:
8 mm: 22
12 mm: 19.7
14 mm: 16.9
16 mm: 14.6
Screw stroke:
8 mm: 20 mm
12-16 mm: 40 mm
Maximum screw speed:
340 rpm for all configurations, infinitely adjustable
This design results in:
Extremely short residence times
Reduced risk of material degradation for temperature-sensitive polymers
High repeatability at milligram-level shot volumes
Injection Forces and Flow Rates
Injection forces:
8 mm: 12.7 kN
12-16 mm: 35.4 kN
Theoretical injection flow rates:
8 mm: 4.02 g/s
12 mm: 20.7 g/s
14 mm: 28.3 g/s
16 mm: 36.8 g/s
These parameters enable controlled, vibration-free filling around inserts.
Procan ALPHA Control System
The BOY XS V is equipped with Dr. BOY's advanced Procan ALPHA control system, which provides:
Up to 8-stage injection speed control
Up to 8-stage holding pressure control
Closed-loop injection and back-pressure regulation
Real-time process monitoring
High cycle-to-cycle repeatability
This ensures stable production even within very narrow process windows.
Ejector System and Part Removal Safety
Ejector technical data:
Maximum ejector stroke: 50 mm
Ejector push / pull force: 8.4 / 8.4 kN
Due to the vertical machine design, parts can be discharged safely by gravity or removed by automation systems positioned on the rear machine table.
Hydraulic System and Energy Efficiency
General technical data:
Installed drive power: 3.0 kW
Total installed power: 4.83 kW (400 V)
Hydraulic system pressure: 300 bar
Oil tank capacity: 28 liters
Dry cycle time (EUROMAP 6): approx. 1.5 seconds
These values make the BOY XS V one of the most energy-efficient machines in the vertical insert injection segment.
