Two Krauss Maffei injection moulding machines were supplied to BMW's production plant at Leipzig, Germany for the new BMW i3, which went into production in September 2013.
Krauss Maffei of Munich, Germany supplied two double swivel plate injection moulding machines, complete with industrial robots that produce multi material plastics components.
The MX 4000-17200/12000/750WL injection moulding machines have impressive dimensions of 24m long x 9m wide x 7m high. Featuring a clamping force of 4000 tonnes, the machines are being used to produce the thermoplastic outer shell and combined substructure of the BMW i3.
The BMW i3 is a five-door urban electric car and is BMW's first zero emissions mass produced vehicle that features carbon-fibre reinforced plastic to improve the vehicle’s energy consumption.
Using the 'joining in injection moulding' process, the outer door shell and its substructure are injected in a single pass, then joined when the two swivel plates turn, and bonded with a third plastic component, the combined work processes ensuring very high dimensional accuracy of the parts.
The Krauss Maffei injection moulders have been specifically developed for the project and produce the sidewall panels, rear bumper and hoods for the new generation BMW i3s.
