One of the newest cured-in-place gasket materials on the market is Vitralit CIPG 60200 from Hoenle Adhesives Americas Inc. This UV-curing polyacrylate material is specifically engineered for high-performance electronic housings in automotive and electric vehicle applications.
When dispensing form-in-place gaskets—for example, on the die-cast housing of an automotive control unit—it’s important to apply the material precisely along the contour of the part. On the housing, the contour runs partly in a straight groove, partly around corners and screw locations and partly along various radiuses. In the area where the plug housing will be installed, the material often must be applied on a ramped surface. All this makes consistent, gap-free dispensing difficult.
The new DC803 Dispensing Cell from Scheugenpflug GmbH promises to make the process faster, easier and more reliable.
When an assembly process proves to be even a tad too costly—even a penny or less per cycle—a cheaper alternative must be found. This is why many manufacturers have replaced die-cut or molded solid gaskets with form-inplace (FIP) and cure-in-place (CIP) liquid gaskets.
The latest generation of pressure-sensitive adhesives and converted materials offer great potential for product improvement. They hold the key to better product performance, greater manufacturing efficiencies, better staff utilization, and ultimately across-the-board cost reduction.
DETROIT—Henkel Corp. has introduced a series of electroceramic coatings, polyacrylate gasket materials and porosity sealants for assembling powertrain components.
