SmartPower The system highlights » Servo drive is standard for the hydraulic system (“Drive-on-Demand”) All SmartPower machines are equipped with a combination of fast-responding servo motors with highperformance fixed displacement pumps as standard. The system benefits are extreme dynamism, high speed and precision of the machine movements and minimal energy consumption. » Plasticizing unit – compact, maintenance-friendly All SmartPower plasticizing/injection units are pivotable and designed for easy access. This offers optimal conditions for quick access to the screw. Optionally a servo electric...

CLAMPING UNIT A perfectly balanced power pack » Ample space for the mold and for symmetrical force distribution Generously dimensioned mold platens and a clamping system with perfect symmetrical force distribution provide an optimal environment for all kinds of injection molding tools, including all types of media connections. [1] » Sensitive and precise Within the SmartPower clamping system, the exclusive task of the tie bars is force transmission between the external platens. Without tie bar contact, the moving platen travels on the linear bearings virtually free of friction [2]. In very few...

INJECTION UNIT Versatile precision » Everything designed for series stability – All screws > 25 mm come with a 22:1 L/D ratio. – Ultimate repeatability with an optional controlled servo valve – Momentum-free nozzle system thanks to axial positioning of the travel cylinders [8] – Plasticizing barrels can be fitted to different injection units with identical screw diameter – WITTMANN BATTENFELD HiQ software modules (optional) offer sensitive control strategies to compensate external factors such as temperature, moisture, regrind or masterbatch content variations. » Optimal operability and flexibility...

DRIVE TECHNOLOGY Energy efficiency with “Drive-on-Demand” Fast-responding, precise, thrifty “Drive-on-Demand” is the innovative combination of a fast-responding, speed-controlled, air-cooled servo motor with a fixed displacement pump. This drive unit is only activated when required by movements and pressure build-up. During cooling times or cycle pauses for parts handling, the servo drive remains switched off and thus consumes no energy. In operation, “Drive-on-Demand” is the basis for highly dynamic, controlled machine movements and short cycle times. The “Drive-on-Demand” system is standard...

INSIDER CONCEPT “ex works” production cell The insider concept is an ex-works solution to transform a SmartPower 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 control system’s monitor. 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...

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 SmartPower The option highlights » Parallel movements Additional pump modules for parallel movements – for ejectors and core pulls – for higher performance (fast injection) Building-up the nozzle contact pressure during mold closing » Servo-electric plasticizing As an alternative to the standard screw rotation drive by a hydro motor, a direct drive with a servo motor is available as an option. It reduces energy consumption and offers additional functions for parallel operation of the clamping and plasticizing units. » Fast mechanical mold change – Quick mold clamping...
