Power backup option - in case of power failure - stops 'short shots' and prevents any mould damages at preform production; it monitors the power supply at every moment.
Technique simplifies production leak testing
Leak test technique simplifies and increases production leak test repeatability and selects the ideal fill and stabilization times based on the volume and temperature of the product.
Concurrently with the PU China, Krauss-Maffei will be launching its new lab facility in Shanghai.
The lab has a PUR mixing and metering system for customer trials and operator training.
It also has facilities for repairing and servicing mixing heads and other machine components.

* Complete solutions from a single contract partner - Krauss-Maffei offers complete solutions for PUR processing - from mixing heads and metering machines to foam moulds, punches and cutters.
Deep integration means that the process, the plant and the tooling can be harmonized very early in a project.
Post-mould processing is designed in from the start.
Depending on product specifications, this could mean flexible cutting, using laser and waterjet cutters, punching and milling.
Krauss-Maffei can supply, for example, a system capable of producing a complete instrument panel - substrate, skin and foam infill layer - together with the cutter systems to trim the edges and create apertures in the part.
The PU China is also an opportunity for Krauss-Maffei to demonstrate its competence in special PUR techniques, such as pour spraying and LFI-PUR.
A feature of Krauss-Maffei's LFI-PUR process is that the long glassfibres are wetted with the PUR mix in the mixing head.
The material is discharged into the open mould, the mould closes and the part is moulded under pressure, so that the glass filaments and the PUR matrix bond into a high-strength composite.
Typical applications are producing lightweight, high-strength parts for commercial vehicles.
* Application-oriented spray systems - with its range of application-oriented spray systems, Krauss-Maffei can deliver solutions for a very wide application spectrum.
Its Pegasus mixing head is the answer for spraying smaller volumes, between 10 and 30 g/s.
Pegasus applications include producing high-quality surfaces on automotive door trim and centre console elements.
For bigger volumes, Krauss-Maffei offers PUR Spray Moulding (PSM) systems used successfully in automotive industry applications such as sunroofs and boot covers.
The hard-metal version of the PSM mixing head is capable of processing PUR formulations with up to 70% barium sulphate, for example, to produce acoustic components with a sound-damping PUR layer.
Krauss-Maffei's new Luchs II mixing head offers several striking benefits in manufacturing sandwich products.
Spraying the polyurethane system via a flat-fan nozzle without air infusion results in uniform material distribution, minimal overspray and a defined spray edge.
