eXtrude In Place
XIP marries the robustness of the material technology
developed by L&L Products and the capability of being a fully automated
process. The material is applied directly and precisely onto
the metal substrates by a robotized extruder. The result is little
to no waste and no tooling required. The material is dry to touch immediately
after application. To optimize the logistic flow, we can design
and install an XIP system that is customized to fit in the logistic flow
between the stamper and the OEM. |

Versatile sealing technology
The ability to apply materials accurately and precisely
to the right location, coupled with custom formulated chemical
components, makes XIP a versatile sealing technology. Water,
air leakage and vapor intrusion into vehicle compartments can
be eliminated with the use of an expandable sealant. Current
applications include fuel filler, hinge pocket, rear lamp and pillar
closures. |

Acoustics improvement
Applied to door beams or roof bows, XIP technology
drastically improves the acoustics by damping vibration. The
expandable material features damping properties and ties all
the individual components together. The XIP application of the
material directly on the substrate makes it a cost effective
and high performance solution. Silent Beam® is XIP. |

Sound management
L&L Products provides outstanding acoustic solutions.
Our material scientists have formulated foams with noise absorption
capabilities and have developed a CAE methodology to design the
best combination of material and carrier design. |
 |
Noise absorption
L&L Products has an extensive range of innovative
materials with absorption coefficient alpha(0°) up to 70%, where
a standard sealing material reaches only 20%. We collect
a full range of data to characterize our materials:
- damping ability
- dynamical rigidity
- transmission loss
- air flow resistivity
- porosity
|
Virtual development
CAE simulation allows further optimization of acoustic
performance of our baffles. Various geometries (i.e. race track, sandwich,
layer), different carrier materials and different thicknesses are simulated
easily using acoustic softwares. |
