polymer in the fi nal third of the plasticising barrel. The Long Fibre Direct Injection Moulding process is still under development but is said to minimise fi bre degrada- tion during processing and offers the opportunity for the moulder to modify the formulation to suit the part. It also promises a cost reduction over bought-in LFT compounds.


Lightweight technology The Particle-foam Composite Injection Moulding (PCIM) process, developed by Ruch Novaplast, was also demon- strated. This technique allows an expanded PP foam to be combined with compact polymers such as ABS, PP or TPE during the injection


moulding process. During the Technology Days event, the company demonstrated production of a model airplane wheel produced on an Allrounder 370S machine equipped with a Multilift V robot. The robot was used to place the foamed tyre core into the mould where the hub was moulded before the part was encapsulated in a TPE. The part was then demoulded and packaged automatically. Mouldmaker Krallmann is


working with Ruch Novaplast to further develop the PCIM process to allow production of the foamed PP element to be integrated into the injection moulding process. Applica- tions are seen in a variety of applications requiring stiff


lightweight structures, including panels and chassis parts for medical equipment. With the K show now


approaching fast, technical director Kraibuhler provided some insights into what the company may show on its stand in October. The company will not, he said, further

increase the upper limit of its machine range beyond 500 tonnes. However, expect to see larger all-electric options and more energy effi ciency features introduced across the range. “Our utmost target for 2013 is the energy effi ciency of our machines,” he said.  www.arburg.com
