either 1,600 or 2,000 kN, as required. In future, it will be possible to select injection positions using modules. Initially one horizontal and one vertical injection unit (V-position) will be available as standard. Horizontal L-shaped (L-position), parallel vertical or parallel horizontal (P-position), and angular (W-position) injection units will additionally be available as options. This will enable all com- mon two-component applications to be realised. Arburg adds that there is plenty of free space for
moulds, rotary units, media connections and a usable ejector stroke. The tie-bars have been extended by 200 mm as standard and the moving mould mounting platen has also been enlarged by 200 mm. The distance between tie-bars is 570 × 570 mm, and the maximum platen daylight 1,200 mm. The sliding guard has also been widened by 400 mm. Together, all these features facilitate accessibility to the mould area. Special emphasis has been placed on ease of maintenance and use, adds Arburg. Among such features are plug-in media couplings for electrics, water and hydraulics. The cylinder module can be changed in a few easy steps. The vertical injection unit can be conveniently positioned on a support frame, placed on the ground and transported separately from the machine if required. The material is fed outside the mould area so it cannot be contaminated by granules. Hose guides optimise hose routing and prevent possible chafing marks. With its numerous improvements to details and modular design, the new Allrounder More series meets all the requirements of a modern multi-component machine, says Arburg. It offers added flexibility for precision configuration and greater efficiency in the production of high- quality plastic parts made from different materials and colours.
Another innovation for Allrounder injection moulding machines regarding manufacturing of transparent visual components in cars is a turnkey solution for flushing the material infeed zone on the moulding unit with the inert gas nitrogen. “This prevents material decomposition caused by oxidation during the preparation of a melt that can cause black spots or yellow discolouration and would constitute rejection criteria in terms of product quality,” says Witte. “The supply of nitro- gen is designed as a compact unit with integrated flow rate measurement. The desired amount of gas can be adjusted easily and accurately using a pressure regulator. Nitrogen flushing is advisable for melts at risk of oxidation, for example, when processing PC and glass substitute materials such as COC and COP.”

Engel says the automotive industry has returned
to more robust business levels, with investments being made again worldwide. “The focus is now clearly on electric mobility, and that requires innovative injection moulding solutions,” says Franz Füreder, Vice-President Engel Automotive. “How- ever, the fact that the production lines in some plants have come to a standstill due to the chip shortage is already having an impact on invest- ments in injection moulding technologies. The next few weeks and months will show the extent to which this will have a lasting impact on growth.” Autonomous driving, connectivity and car-sharing
are among the major trends, and sustainability and recycling are further innovation drivers, as shown by the example of electromobility, says Füreder. Sustainable mobility demands that components which are made of fibre reinforced plastic compos- ites are returned to the materials cycle at the end of the vehicle’s service life. So far, this has not been practised in many cases. Engel has a viable solution to this challenge in the form of its Organomelt technology because it enables the production of components all based on thermoplastics. Applications requiring new solutions regularly involve lightweight construction, as well as sensor technologies and functional surfaces. In some cases, completely new applications are developing. “We are also seeing an increasing demand for multi-component solutions, for injection compres-
