U850 features a modern HMI with clear operational menus and diagnostic
pages to streamline setup and production. The machine supports robot
interface connectivity for automated part removal and downstream
handling. Electric dosing and precise plasticizing power ensure stable
melt quality and repeatable cycles. Safety controls and process
monitoring are integrated through the control interface to maintain
consistent, high-quality output.HMI control: multi-page interface with

monitoring: live readouts for temperature, times, positions, and
pressuresProduction Line Integration CapabilitiesThis injection
molding machine integrates seamlessly into industrial packaging and
beverage production environments, supporting automated cells with
robots, conveyors, and quality control stations. Its robust clamping
unit and generous tie-bar spacing accommodate multi-cavity molds for
components used in used bottling line refurbishments and second hand
production setups.Compatible with automated part removal robots and
conveyorsSupports quick tool change practices with ample platen
accessSuitable for industrial packaging components and beverage
production accessoriesMachine Condition & Maintenance HistoryThe
machine is presented in working condition and ready for operation. Its
technical characteristics are verified via the onboard HMI, with
parameters aligned to the 100 mm screw configuration. The presence of
robot interface and core pullers indicates readiness for automated
cell deployment.Operational Performance & VersatilityWith 8500 kN
clamping force and large shot capacity, the U850 handles sizeable
parts or high-cavitation molds with consistent melt preparation. The
electric dosing motor supports stable plasticizing, while hydraulic
pressures and long opening stroke enable robust tool operation. These
capabilities make it suitable for a wide range of industrial packaging
parts, beverage production accessories, closures, and technical
components used across bottling equipment and packaging
machinery.Installation Requirements & Site PreparationEnsure adequate
floor space for the machine footprint and safe perimeter access for
tool changes and maintenance. The installed power for the 100 mm
configuration is 198 kW; utilities should be sized accordingly.
Provide compressed air for auxiliary circuits and robot end-of-arm
tooling, and allow clear overhead access for mold handling
equipment.Footprint: 11550 x 2600 mmHeight clearance: 2305 mm minimum

for up to 198 kW installed power; compressed air for auxiliariesSafety
Standards & Compliance CertificationThe U850 is engineered with
standard safety guarding and interlocks to protect operators during
clamping, injection, and ejection sequences. Emergency stop systems
are integrated via the control interface. The machineâs
construction and guarding concept support deployment in industrial
packaging and beverage production environments where safety and
hygiene practices are critical for consistent operation.
