Adhesive application (factory
for interior materials for automobiles)
This manufacturer has formerly used an automatic
spray gun to apply adhesive in the pressing process used for gluing
together interior materials for automobiles, but the following
· Adhesive became stringy
· Width of coating that the spray provided
was too narrow.
· Misted drifted up, deteriorating the
PR-30W (φ1.5) automatic spray gun,
which has separate systems for atomization air and pattern air,
was used. Low pressure was selected for air atomization, and pressure
for pattern air was set higher than it. This enabled a 30-40%
wider pattern to be sprayed, with no stringiness. In addition,
there was little scattering, which improved the work environment.
