Noise insulation (acoustic foam) - HL spraying

Acoustic foams are used in carpets, bulkhead panels or motor casings. The goal is to both absorb airborne noise and dampen structure-borne noise to reduce the interior noise emissions to a minimum. Here, carpets can be back-foamed completely or only partially. A specific spray application of highly filled PU systems can partially influence noise properties.

KraussMaffei provides you with the right systems engineering to be able to produce premium quality components. The system concepts are adapted to the custom requirements and consist of filler handling, metering technology, if necessary spray technology for highly filled PU systems, mold carriers, molds and the required peripherals for completing the entire machine. Depending on the system concept, circular tables can also be used for holding the mold carriers and molds.


  • Mold carrier for open or closed mold pouring
  • Mold carrier also for open foaming for large-format carpets
  • Clamping forces adapted to the application
  • Spray technology for highly filled PU systems
  • Wear-protected mixing heads for high service lives
  • Complete solutions including filler handling, metering technology, mold carriers and foaming tools
