UNDER THE HOOD | AUTOMOTIVE
workpiece carriers in a drawer system. For easier positioning in the mould of an electric Allrounder 470 A with a clamping force of 1,000 kN, the stamping frames contained two pre-moulded parts each. The inserts were first cleaned with Openair- Plasma and coated inline using the Plasma- SealTight (PST) process. A vertical Multilift V robotic system combined two identical parts into one assembly, which is then placed in the mould as an insert. Next, the Allrounder 470 A overmoulded the inserts with glass-sphere reinforced PA6 (GB30) to produce the finished hybrid connector. The plasma coating ensured media-tight and corrosion-free connectors without needing to use solvent-based primers. The cycle time was around 60 s. Arburg also demonstrated how highly flexible
production can be achieved without conversions using an electric Allrounder 370 E Golden Electric. The standard machine was equipped with a family mould and alternately produced magnetic cog wheels and rotors to demonstrate that it is possible to work with two injection and mould programs without additional programming effort. The magnetic parts can, for example, be used in the field of e-mobility.
The electric Allrounder 370 E Golden Electric with a clamping force of 600 kN was equipped with a 1+1-cavity family mould. When changing products, the second stored injection and mould program simply needs to be selected and the sprue channel in the mould is changed. A magnetised cog wheel with eight poles and a diameter of 48 mm, or a rotor with four poles and a diameter of 34 mm, can be produced alternately in a cycle time of around 85 s. The exhibit processed a plastic-bonded magnetic compound based on
