Fakuma showcasing the latest

THE Fakuma show, held in Germany from 16-20 October, featured highlights from machine makers like Arburg, Engel, KraussMaffei and mould maker Fohoba and welding specialist LPKF. Arburg showcased its Particle-foam Composite Injection Moulding (PCIM), longfibre direct injection moulding and inline printing. It also displayed its new electric Allrounder 630 A, the productivity package for the Golden Edition series and the servo-hydraulic drive concept for the large Allrounders of the S series. In fact, the firm has over 20 Allrounders on show throughout the Fakuma, ten of them on its own stand.

Arburg’s new long-fibre direct injection moulding process is developed together with SKZ German Plastics Centre in Würzburg. It allows inline feeding and enables longer fibres to be processed, so that lightweight injection moulded parts with thin walls and high strength can be produced. Particlefoam Composite Injection Moulding (PCIM) is a joint project with Krallmann and Ruch Novaplast in which a foamed part is combined with plastic.

The two components are bonded, so that there is no need for subsequent assembly steps and a finished part is produced in a single step. This opens up a whole field of new options for the electric mobility, lightweight construction and insulation sectors.

With the inline printing Inkbot process from FPT Robotik, which combines digital printing and robotics, it enables parts with irregular geometries and curves to be printed.

German mould making company Foboha presented its all-electric stack turning and cube moulds at injection moulding machine maker Ferromatik Milacron’s stand at the show. Foboha engineers came up with the servodriven solution to the market standard all electric injection moulding machines after searching for ways to make stack turning and cube moulds entirely without hydraulic drives, surmounting the issue on how to integrate the necessary servo drives into the mould. All drives (axes) of the new design, from the ejector via the reversing unit to the handling unit, are fitted with electric motors. The electric moulds are targeted at the medical, pharmaceutical and food processing fields.

In laser plastic welding, LPKF showed its LQ-Vario and LQ-Spot systems for the medical sector. The system on display at the show will be equipped with a rotary indexing table, and can also be fitted with two component compartments for faster throughput. With the LQ-Spot, a technique for fastening elements inside housings is shown. The system welds on a small cap to fix small integrated components rigidly in place with no mechanical or thermal stress. Another product still in the development stage is the new tabletop machine specially developed for prototypes and small series.

Producing moulded parts of a consistently high quality shot by shot is the aim of Austrian firm Engel’s new software iQ weight control. The patent-pending system analyses the pressure profile at screw positions in real time during the injection process and compares the measured values with a reference cycle online.

This comparison is used to calculate a new set of process parameters that allow changes in melt volume and material viscosity to be detected immediately. Another machine maker KraussMaffei also presented its new GX series, which the firm has already showcased in Europe and Mexico to customers from the electrical engineering/electronics, consumer goods, packaging and automotive industries. During Fakuma, a GX 450-3000 had produced a telephone cradle for an automotive interior using MuCell technology. (IMA)
