WITTMANN BATTENFELD at Fakuma’15: Highlights Medical Technology Competence

Published on 2015-10-13. Author : SpecialChem

WITTMANN BATTENFELD demonstrates its medical technology expertise to trade show visitors with two exhibits at Fakuma in hall B1, booth 1204.

Over the last few years, WITTMANN BATTENFELD has shown that the company’s technologies are ideal for clean room applications, particularly its all-electric machines from the EcoPower and MicroPower series. Based on their strong experience in the sector, WITTMANN BATTENFELD has decided to extend its activities in the area of medical technology, and to develop its machines further to better meet the current requirements of customers in that industry.

As such, it was decided to roll out a “Medical” version of the all-electric EcoPower first, and then qualify it in a clean room. For this purpose, an ISO standard class 6 clean room from Max Petek Reinraumtechnik, Germany was installed at the WITTMANN BATTENFELD plant in Kottingbrunn, where the machine was then thoroughly examined. Simultaneously, GMP (good manufacturing practice) standard machine documentation has been made available for machines of the Medical version. In this way, WITTMANN BATTENFELD has established the necessary prerequisites to meet the market demand in respect of both machine capability documentation and software. The clean room measurements are carried out under both dry running and production conditions in order to obtain results that are as clear and accurate as possible concerning the equipment’s emissions. The installation of the clean room now gives the company’s customers an opportunity to carry out production tests for tooling acceptance at the Kottingbrunn facility under real–world conditions.

In further developing the all-electric EcoPower for clean room applications, special attention was paid to optimizing the interior mold space, which comes equipped with smooth surfaces, stainless steel covers and covered guide rails. The exhaust air conduits of the pneumatic valves are bundled and thus guided out of the clean room. Moreover, the machine as a whole has been provided with a water cooling system with a closed cooling circuit, special alcohol- and solvent-resistant paint, nickel-coated clamping plates with covered threaded drillings and a laminar flow box, which supplies air with low particle content to the interior mold space. All openings in the mold area and the threading of the clamping plates are covered. The barrel insulation also minimizes emissions into the environment. For lubrication, exclusively “food grade” lubricants are used.

The machine series MicroPower and SmartPower are the next to undergo medical clean room qualification.

At Fakuma, the functionality of the EcoPower’s clean room model is demonstrated by the production of a contact lens tray made of PP on an EcoPower 110/350. In addition to the features already mentioned, the machine on display at the fair is equipped with a good part / reject separator and an encapsulated clean room conveyor belt from Max Petek Reinraumtechnik, mounted below the clamping unit. The parts fall freely onto the encapsulated clean room conveyor belt and are subsequently transported to a laminar flow workstation.

The second exhibit relating to the theme of medical technology is the medical technology version of a MicroPower 15/10. On this machine, a PEEK micro catheter, used for taking samples of peripheral tissue, with a weight of about 20 mg is produced with a single-cavity mold supplied by Ernst Wittner GmbH, Austria. The machine on display comes as a full-fledged clean-room production cell, equipped with a rotary disk, parts removal handling device, integrated quality inspection by image processing, as well as a clean-room module, which produces class 6 clean air according to the ISO 14644-1 standard. The parts are all injected, quality-inspected and deposited inside the clean room.
