Micromoulding will play a key part in the technology that will be showing on the Wittmann Battenfeld UK stand at this year’s Interplas exhibition, September 26 – 28, 2017.
Attendees at the Polymer Process Engineering (PPE) event, Bradford University July 25-27, were recently treated to an update on all the micro and nano moulding work being undertaken at Bradford. A long-standing partner of Wittmann Battenfeld, the University is a world leader in many aspects of micromoulding technology.
Since Wittmann’s acquisition of Battenfeld on April 1, 2008 the company’s world-leading expertise in polymer micromoulding has gone from strength to strength. Wittmann has encouraged the modular construction of the micro moulding machines – from standard all the way up to Class 6 Cleanroom modifications and capabilities. The principle of the central main beam as the base, for example, has been borrowed from the Wittmann vocabulary of robot design, with several modules being attached to the main beam.
From the outset, the Wittmann Battenfeld MicroPower moulding machine has been designed with cleanrooms in mind and with low energy and ergonomics to the fore. Small centre holes, for example, allow the engineering of very small parts. Small ejector plates avoid any bending of the support plate and small ejector and nozzles holes allow central power flux.
Wittmann Battenfeld also created a two step system within the machine, separating the plasticizing and injecting functions. This in order to avoid a large melt cushion (less accurate); cold material slug on the nozzle; long flow lengths and additional shut-off valves.
Interplas 2017 will see the latest MicroPower injection moulding machine producing the ‘lab on a chip’ micro-component. The latest iteration of this process was first shown at the Compamed exhibition in Dusseldorf in November 2016.
