WITTMANN BATTENFELD at the Compamed: Micro Injection Molding with LSR

From 12 to 14 November 2014, WITTMANN BATTENFELD will be presenting latest injection molding technology to interested trade visitors in hall 08b, booth F03 at the Compamed in Düsseldorf, the leading international trade fair for suppliers to the medical technology industry.

On a machine from the MicroPower series specially designed for injection molding of small and micro parts, WITTMANN BATTENFELD demonstrates its possibilities of LSR processing by showing lenses for medical devices being produced from highly transparent liquid silicone. LSR is gaining more and more significance in the optical sector as well as in medical technology.

On a MicroPower 15/10, lenses will be manufactured on a 4 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 supplied by EMT Dosiertechnik, Germany, from two 1-liter cartridges to the injection unit.

The MicroPower stands out by its extreme cost-efficiency, process reliability and speed. In this machine generation, the injection aggregate is of special interest. This innovative two-step injection unit, consisting of a screw and a plunger, with a shot volume ranging from 0.05 to 4 cm³, injects thermally homogeneous melt, with the result of premium-quality parts from absolutely stable production with short cycle times.

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.
