The Clock Is Ticking
As in previous years, Arburg GmbH + Co KG in Lossburg, Germany, continues to focus on lightweight construction. For this, Arburg will present the ProFoam physical foaming procedure that was developed in cooperation with the Institute for Plastics Processing (IKV) in Aachen, Germany. With this version of foam injection molding, the material is surrounded by a gas atmosphere already in its solid state. Therefore – as opposed to other physical foaming procedures – conventional injection molding machines without a specially adapted plasticizing unit can be used. In addition to a ProFoam granulate lock, which is under a gas atmosphere and replaces the conventional material hopper, the plasticizing unit must only be fitted with a needle valve nozzle, and a rear seal for the screw must be ensured. The new foaming method enables lightweight components with a homogeneous foam structure and low distortion to be produced. In combination with dynamic mold tempering, it is also possible to obtain high-gloss component surfaces.
It will also be interesting to see whether the further development of particle foam composite injection molding announced at the last Fakuma has reached the next stage. For quite a while, Arburg has been working together with its partners Krallmann and Ruch Novaplast. The latest news involved a vapor-free pre-stage of particle foaming (before being combined with the injection process).
For Arburg, Industry 4.0 continues to be a focal point of development. For 30 years the Lossburg company has been involved in networked production, and back at the K 1986 introduced a fully automatic production system without manual setting up, which consisted of several catenated injection molding machines. During recent years, the subject of individualization has become increasingly important. For this, Arburg has combined injection molding with additive manufacturing in a data-networked and fully automated production line. This time, it is unlikely to be simply a light switch with individual inscription or a pair of office scissors.
Apart from the majority of applications with thermoplastic materials, Arburg will demonstrate the two-component injection molding of a wristwatch from two liquid silicone rubbers (LSR). The manufacturing cell also includes assembly of the watch case.
