WITTMANN BATTENFELD demonstrates its competence in LSR (liquid silicone rubber) micro injection molding

From 3 to 5 June 2014, WITTMANN BATTENFELD will present an interesting micro injection molding application to trade visitors at booth 5B10, at the Medtec Europe in Stuttgart, the leading European medical technology fair.

With its electric machines – the all-electric EcoPower series and the MicroPower series specially designed for injection molding of small and micro parts – WITTMANN BATTENFELD has developed over the last few years into a competent partner for the medical technology industry and is again using the Medtec in 2014 as an important platform to demonstrate its competence in this area.

LSR micro injection molding in a clean-room environment

The company will present hands-on evidence of its know-how in this area by processing liquid silicone rubber into micro parts, a product line gaining more and more significance in medical technology. On a MicroPower 15/10, dust protection caps for mini jacks will be manufactured on a 2-cavity mold supplied by Awetis, Germany, from 2-component liquid silicone rubber supplied by Momentive, Germany, with the material being conveyed by a dosing pump from two 1-liter cartridges to the injection unit. The surface of the parts is embossed with micro structures engraved into the mold by means of laser technology.

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. Thanks to its clean-room-compatible design and the clean-room module, which produces class 6 clean air according to the ISO 14644-1 standard, it is an ideal platform to produce high-quality medical parts. In the application demonstrated at the fair, the parts are all injected, quality-inspected and deposited inside the clean room.
