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 would be customized to fit in the logistic flow between
the stamper and the OEM.
Versatile sealing technology This ability to apply materials acurately and precisely
to the right location coupled with custom formulated chemical components
make XIP a versatile sealing technology. Water, air leakage and vapor
intrusion into vehicle compartments can be eliminated with the use of
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 we developed a CAE methodology to design the best combination of
material and carrier design.
Noise absorption Our company has an extensive range of innovative
materials with absorption coefficient alpha(0°) up to 70%. 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.
