LFI lightweight construction
The LFI lightweight technology is a further development of the LFI technology, which has been used very successfully since 2004.
This technique is perfectly suitable for large structural components (maximum mold clamping surface: 2,600 x 2,000) and is primarily used in the recreational vehicles sector. This procedure ensures a highly reliable manufacturing process of complete front and rear panels for travel trailers and campmobiles. In addition to long-life cycle, stability and design freedom, the LFI lightweight technology also implements special sector requirements, such as weight reduction and high insulation properties.
Due to the application of Class A films a varnishing of plastic parts is no longer required.
Whether you use PC-ITR, ASA/PC-PMMA or ABS-PMMA, these films are first of all formed as outer layer in a vacuum thermoforming process and afterwards foam-backed via LFI procedure.
During the process a robot inserts the compound, consisting of glass fibre and a specially modified polyurethane, into a mold.
We have been applying LFI lightweight technology in Neureichenau since 2009. This procedure is most successfully used for different caravan manufacturers.
