Major advantages of MK6.6 Euroseries

• Machine intelligence and ergonomics Optimised control and operator access for industrial production.
• Proven toggle design Motion-control profile tuned for high speed and stability.
• High-strength platens Patented construction reduces platen deformation for uniform clamping.
• High-precision injection unit Linear guide rails for injection ensure stability and repeatability.

Toggle design from decades of experience
Experienced mechanical engineers refined the toggle kinematics using software simulation and real-world validation. The result is reduced internal friction and shocks, uniform load distribution across tie-bars and maintained platen parallelism to minimise flash and wear. The system delivers smooth, vibration-free motion, improved power efficiency and extended component life.

Integration of toggle and hydraulics
Hydraulic circuit optimised via fluid-dynamics simulation and fine tuning to provide fast, precise and repeatable clamping and injection control suitable for high-throughput production.

Strong platens for consistent part quality
Patented low-deformation platens with reinforced centre deliver more uniform clamping force on the mould, protecting tooling and improving finished-part dimensional stability.

Controls

• B&R 10.4" professional controller Integrated automation for high-speed applications and cell-level management.
• User-friendly multi-touch HMI Clear process visualisation and intuitive operation.
• CAN-Bus I/O and customised control Fast response and reliability, controller tailored for MK6.6 series.

Production case example

• Part example — LED lighting part Shot weight: 121 g; Cavities: 8; Resin: PC; Cycle time: 32.4 s.
• Mould Weight: 350 kg; Dimensions: 400 mm x 400 mm x 300 mm.

Performance highlights
Improved dry-cycle and injection speeds versus comparable examples. Production simulation indicators: up to 11 months per year, 21 hours per day; energy consumption example range 0.17–0.35 kW·h; estimated 8 million shots in 10 years and example energy saving ~€29,400 over 10 years (simulation-based figures).
