The group will exhibit a MicroPower 15/10.
By developing the electric machines in its PowerSeries range, the group says it has optimised its offering for medical applications and implementing cleanroom systems. Specifically, the all-electric EcoPower and MicroPower series will be in focus during the event.
A micro filter made of POM with an 80µ grid and a part weight of 1.1mg, which can be used in acoustical engineering as well as in micro pumps or inhalators, will be manufactured on a MicroPower 15/10, which has been specially developed for high-precision injection moulding of small and micro parts. It will be produced in a 2-cavity mould with 3-platen injection.
Of particular interest on the MicroPower, according to Wittmann Battenfeld, is the injection aggregate. The two-step injection unit consists of a screw and plunger, with a shot volume ranging from 0.05cm³ to 4cm³ offering stable production and short cycle times.
The recently-developed Hi-Q shaping injection-compression moulding process is said to offer the production of parts with virtually no internal stress and excellent surface finishes. Here, the process parameters for temperature and pressure are added to the settings for time and distance, which makes it possible to regulate the embossing pressure via the clamping force setting for every specific process. This enables accurate application of the embossing pressure to the entire surface of the part just above the glass transition temperature, causing a drastic reduction in material stress.
The machine on display is a completely integrated clean-room production cell with a rotary disk, parts removal handling, integrated quality inspection by imaging and a cleanroom module. The machine’s cleanroom-compatible design plus the cleanroom module enable a class-6 clean air environment according to ISO 14644-1. In the application demonstrated at the fair, the parts will be injected, inspected and deposited inside the clean room.
