MEDICAL Machines for clean room production world of innovation

WITTMANN BATTENFELD MEDICAL For ultra-clean products WITTMANN BATTENFELD injection molding machines are targeted to a minimal emission level as standard. Clamping units with lubrication-free tie-bars, encapsulated drive systems and an easy-to-clean mold space with smooth surfaces provide favorable conditions for contamination-free components production. For manufacturing in a controlled clean-room environment, these standards can be raised to meet the requirements for the clean room classes according to EN-ISO 14644 with specially adapted MEDICAL equipment upgrades. These packages, based on...

Always the right machine » MicroPower MEDICAL All-electric injection molding machine in clamping force size of 15 t with shot volumes ranging from 1.2 to 6 cm3 (*) The intended purpose is the production of micro parts with specified standards of cleanness. This includes medical components as well as parts for electronics, optical applications and fine tooling. » SmartPower MEDICAL Servo-hydraulic all-round injection molding machine in 18 clamping force sizes from 25 to 400 t with shot volumes ranging from 13.9 to 2128 cm3 (*) Multi-purpose machines for manufacturing small and medium-sized...

MicroPower MEDICAL Clean room micro injection molding Facts and figures » Micro injection molding machine with all-in machine frame » For shot weights ranging from 0.05 to 4 g » Generous free mold space » Encapsulated 5-point toggle lever clamping system » Clamping unit in two sizes with 5 and 15 t clamping force » All movements directly electrical, powered by servo motors » Machine frame laid out for the integration of robots and quality inspection stations as standard » Available also as 2-component machine with a second injection unit and integrated rotary table For technical details,...

MicroPower MEDICAL The system highlights » Stand-alone clean room cell Through combination with an air filter and laminar flow unit, the machine frame cell of a MicroPower machine, which is closed on all sides, becomes a MicroPower clean room cell according to EN-ISO 14644 standard / class 9 to 7. » Ample space for peripherals The closed cell of the MicroPower machines offers sufficient space for integrating optional equipment, such as a rotary table, robot, material dryer, temperature control technology and other product-specific options, and can thus be extended into an “all-in”...

SmartPower / EcoPower MEDICAL For high quality standards in medium-sized precision parts Facts and figures » SmartPower and EcoPower are the medium-sized machine series from WITTMANN BATTENFELD, of which the former contains a hydraulic clamping unit combined with servo motor drive technology, and the latter combines all-electric drives with a 5-point toggle lever clamping unit. » The SmartPower machines are available in 18 clamping force sizes from 25 to 400 t clamping force and are a cost-efficient option for the production of clean parts in many areas thanks to their attractive...

SmartPower and EcoPower MEDICAL The optional highlights » Easy-to-clean mold space The mold platen drillings (EUROMAP) can be temporarily closed with plastic stoppers. The surroundings of the mold platens are lined with easy-to-clean stainless steel panels. If desired, the machine platens can be supplied with a reduced bore pattern. » Controlled exhaust air disposal Undesirable disturbance variables in the clean room include the hot air and plastics vapor generated around the barrel during the injection process. Therefore the barrels on MEDICAL machines are covered by an encasement and...

THE MOLD SPACE A clean production center A “clean” environment is not just a temporary issue for the moment of quality certification, but this state must be easy to maintain permanently. WITTMANN BATTENFELD offers the necessary detail solutions. » Encapsulated media connections All media connections are located at the rear of the machine next to the mold space. Fold-back covering panels form a housing to encapsulate the components for media supply and distribution. » Lubrication-free tie-bar system The moving platen of the machine travels on a carriage without coming into contact with the...

MEDICAL MODULE SYSTEM For clean room injection molding Since there is more than just “one” type of clean room production, a comprehensive range of equipment options and services is available for individual adaptation of the basic equipment to special needs. » Equipment options according to EN-ISO 14644 classes 9 – 7 – Paint resistant to alcohol and disinfectants – Nickel-plated clamping plates – Drillings in the clamping plates with covers – Easy-to-clean mold space – Lubricants in H1 (NSF) quality – Petek laminar flow module (LMP) – Exhaust air suction device mounted on barrel – Barrel...

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 peripheral 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 peripherals via WITTMANN 4.0 » WITTMANN FLOWCON plus water flow regulator, GRAVIMAX blenders and ATON dryers – Units directly addressed and controlled via the machine’s...

APPLICATION TECHNOLOGY Well above standard Photo: Rohde & Schwarz » LIM – Liquid Injection Molding LIM designates the injection molding process for making elastic parts from 2-component liquid silicone rubber (LSR). LIM micro parts are used for optical and medical applications and are mostly produced under clean room conditions. » High-precision micro parts In addition to standard plastics processing, the MicroPower injection unit is an ideal choice for manufacturing high-precision parts from engineering plastics such as POM, PEEK or PSU, without having to compromise on accuracy or...
