Automotive interior

Complete value creation from a single source: In addition to the polyurethane processing machines, KraussMaffei also supplies molds, mold carriers and trimmer technology for projects in the automotive interior.

Technology

Instrument panel back-foaming

The requirements for modern mold carriers for instrument panel back-foaming are versatile and complex. Our molds are designed specifically for your application.

Seating foams

Each system for manufacturing articles from flexible foam requires a quality standard down to the smallest detail. It is therefore a good idea for everything to come from a single source – from one experienced manufacturer who sets the bar for quality extremely high.

 

Inner door panel/arm rest/center console

Flexible foam systems are generally processed on high-pressure metering machines. while high mixing quality ensures splash-free pouring into the mold. Semi-rigid foam is the manufacturing of door side panels, arm rests and center consoles.

Structural foam

Functional parts in the automobile such as steering wheel, shift knobs, grips or arm rests are often made from PU soft integral foams that combine both an excellent look and feel with high wear resistance. Designers are offered various design options in relation to geometry and surface structure.

KraussMaffei provides you with the right systems engineering to be able to produce premium quality parts. The system concepts are adapted to the custom requirements and consist of metering technology, mold carriers, molds and the required peripherals.

Soundproofing (acoustic components)

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.

Scoring/cold-knife cut

KraussMaffei defines scoring as the process used to attach a predetermined breaking point in the airbag area into the decorated film of instrument panels.

Deflashing

Deflashing parts that have been back-injected with film involves the fully automated removal of left-over bits of paint. This occurs using a special deflashing tool, where an industrial robot guides the special deflashing tool along the part contour.

Milling tool / spindle

Milling tool / spindle

  • KraussMaffei uses premium quality spindles and milling tools as its standard.
  • Milling tools 6 mm in diameter are used for normal cutting dimensions.
  • Generally, a smaller milling tool (d=2-3 mm) is used in the carrier for scoring airbags.
  • Optionally, a suction bell is available that extracts the chips right after the cutting process
