In typical sunroof manufacturing operations, glass and metal are attached to the sunroof frame. A sealing adhesive is applied to provide a watertight seal between the frame, metal and glass. However, application of the sealing material can be difficult to control. Excess material often squeezes out of the assembly and results in labor intensive cleaning and rework. Line speeds are slowed for inspection and cleaning operations.

The Nordson FoamMix® system blends moisture-cure hot melt material with inert gas to form a flowable solution. When dispensed, the gas expands to create a closed-cell foam. Foaming the material significantly reduced material density, use and costs. In addition:

The material is precisely applied and moisture-cures quickly, virtually eliminating the problem of material squeeze-out.

In addition to improved product quality, minimized rework results in labor savings, increased line speeds and productivity.
