EcoPower The system-highlights » Direct servo drives for main movements The EcoPower machines come with highly dynamic servo motors to drive the main movements (closing/ opening, plasticizing, injection). The mold height adjustment device in the clamping unit is also driven by a servo-electric motor. The ancillary strokes (ejector, nozzle stroke/contact pressure, core pulls) are driven by an integrated servo-hydraulic aggregate powered by a servo-electric motor. Direct servo-mechanic drives are available as an option. » High-performance injection unit The EcoPower injection units are equipped...

CLAMPING UNIT Servo-electric speed and dynamism » Ample space for complex molds – Generously dimensioned mold platens [1] and a clean toggle lever clamping system offer the optimal environment for all molds including all media connections. – The ejector area and the environment of the platens offer easy access for machine setup and adjustment work. [2] » Sensitive and precise In the EcoPower clamping system, the tie-bars are exclusively used for force transmission between the outer platens. The moving platen travels virtually free of friction across the linear bearings without coming into contact...

INJECTION UNIT Precision from beginning to end » Everything to ensure series consistency – All screws > 25 mm come with a 22:1 L/D ratio. – All injection units offer a wide injection pressure range. – Plasticizing parallel to clamping unit movements and start of the injection process during clamping force build-up are possible as standard. – EcoPower injection units with a higher injection performance can be supplied as an option. – Moment-free nozzle contact thanks to axial configuration of traveling cylinders [7] – Plasticizing units can be mounted to different injection aggregates with identical...

DRIVE TECHNOLOGY Energy efficiency with servo motors Fast-responding, precise, cost-efficient The use of servo-electric drive technology for all main movements affecting the cycle offers a large number of advantages compared to conventional hydraulic injection molding machines: » » » » Energy efficiency through direct drive without energy conversion into hydro energy Energy efficiency through the servo drives’ high efficiency rates Digital control for maximum repeatability Use of recovered braking energy via KERS system for powering of heater bands and bridging of short power failures » Cycle...

INSIDER CONCEPT “ex works” production cell The insider concept is an ex-works solution to transform an EcoPower injection molding machine into a fully fledged production cell. In its basic version, the equipment cell integrates a parts handling system, a conveyor belt for parts transport and a protective housing firmly connected with the machine. Additional equipment modules for further processing, quality documentation and packaging are available as options. For the design and configuration of such higher automation levels, WITTMANN BATTENFELD places the combined expert knowledge of the entire...

UNILOG B8 Complex matters simplified The UNILOG B8 machine control system is the WITTMANN BATTENFELD solution to facilitate the operation of complex processes for human operators. For this purpose, the integrated industrial PC has been equipped with an enlarged intuitive touch screen operator terminal. The visualization screen is the interface to the new Windows® 10 loT operating system, which offers extensive process control functions. Next to the pivotable monitor screen, a connected panel/handset is mounted on the machine’s central console. UNILOG B8 Highlights » Operating logic with a high...

The process in constant view » SmartEdit SmartEdit is a visual, icon-based cycle sequence programming facility, which enables direct addition of special functions (core pulls, air valves, etc.) based on a standard process via touch operation on the screen. In this way, a total user-defined sequence can be compiled from a sequence menu. This machine cycle, visualized either horizontally or vertically, can be adjusted simply and flexibly to the process requirements by finger touch with “drag & drop” movements. The advantages – Icon visualization ensures clarity. – Clear events sequence through...

WITTMANN 4.0 Communication in and with production cells With its communication standard WITTMANN 4.0, the WITTMANN Group offers a uniform data transfer platform between injection molding machines and auxiliary equipment from WITTMANN. In case of an appliance change, the corresponding visualizations and settings are loaded automatically via an update function, following the principle of “Plug & Produce”. Connection of auxiliaries via WITTMANN 4.0 » WITTMANN FLOWCON plus water flow regulator, GRAVIMAX blenders and ATON dryers – Units directly addressed and controlled via the machine’s control system...

OPTIONS Modular and flexible EcoPower The option highlights » Performance increase for injection As an option, a “high-speed” version of the toggle lever drive is available. The injection dynamism and precision of the servo-electric injection units provide the prerequisites for manufacturing thin-walled molded parts with high standards of dimensional accuracy. This enables the production of thin-walled plastic parts for the packaging and electronics industries. » Faster ejection As an alternative to the standard servo-hydraulic drive for the ejector, a more powerful version with a servomechanical...
