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 technical characteristics viewAutomation: robot interface enabled for pick-and-place and cell integrationPower architecture: motor-pump 74 kW; plasticizing and heating 37 kW each (100 mm configuration)Process 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 setupspatible 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 plus allowance for lifting/hoistingUtilities: electrical supply sized 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 machine’s construction and guarding concept support deployment in industrial packaging and beverage production environments where safety and hygiene practices are critical for consistent operation.
