Acoustic Components

Production is diversified by multiple types of foamed polyurethane.

Components may be manufactured in:

  • Low density flexible foam for soundproofing
  • Low density flexible foam for padding
  • Integral flexible self-skinning polyurethane foam
  • Rigid energy absorbing polyurethane

Each type of material has its own equipment to ensure good production flexibility and above all a constant and excellent quality in the produced foams, avoiding washing and pollution among the different materials.
All raw materials and PU systems use are approved in the automotive industry thanks, to the close cooperation with some of the leading manufacturers (BAYER- BASF) who directly support all developments.

Flexible PU is an open-cell foam that allows the realization of different types of components.
Components may be manufactured as fillers for empty cavities, which facilitate the absorption of noises and vibrations.
Or pillows injected into molds for the realization of seats and backrests.

The production of these foams is carried out with low pressure machines of various sizes based on the size of the component.
The appropriate dosages of the two components, polyol and isocyanate, which compose the liquid polyurethane are injected into hot molds.
The multiple proportion variations allow production of components having different densities, different stiffness and therefore different carrying capacities.
By applying two machines on the same mold, materials differing in stiffness and characteristics may be injected. In this manner, it is possible to highlight them with different colors so as to determine the exact position in the component.

Integral foams are special flexible foams such that during the component reaction and filling phase, they have a great expansion energy that they thicken strongly on the mold walls.
This effect produces a substantial skin layer in the component , with excellent results aesthetically as well as utility. In fact, thanks to this particular structure, the parts have a remarkable flexibility and the smoothness of flexible foams, but may be used in areas exposed to fumes and to likely contact with liquids. Normally these components have a density not lower than 200 Kg / M3 or higher. A recent and new generation lightweight integral foam is used. Despite more than a 30% weight reduction compared to standard , the foam maintains an excellent aesthetic appearance, without losing its impermeability to fumes and liquids.

These foams belong to the family of structural rigid materials, have a special open cell rigid structure that creates the necessary component rigidity and stiffness required for absorbing energy in the event of a collision.
This material may mold components which follow mold geometry , or sheet production which may subsequently be trimmed via Water-Jet technology.
Based on the requested characteristics, they may be produced with a density of 55kg / M3 or higher.
