Micro moulding comprises the fields of precision micro parts, microstructure parts and high-precision parts. Their production requires details and tolerances in the micron range. Today, various applications in the medical technology and IT sectors also even extend into the nanometre range.
In the micro moulding sector, the requirements in terms of injection moulding technology are accordingly high. These include the homogeneous preparation and plasticising of tiny material volumes, short dwell times, injection of minimal shot weights, precise control of injection movements and the first-in-first-out principle.
ARBURG continuously develops new technologies for micro-part manufacturers. In addition to ever smaller injection units and screw diameters, complete production cells have already been designed and implemented for micro moulding.
The latest highlight in the field of micro moulding, however, is the new ARBURG micro-injection module, which operates with an 8-mm injection screw. This is combined with a second screw, which is responsible for melting the material. The advantages include continuous material feed from the inlet to the tip of the injection screw, constant injection conditions via dosage control and the processing of standard granulates.
