Product marking for identification
purposes (automotive parts manufacturer)
This manufacturer made springs for automobiles
and had previously used another company's automatic spray guns
to mark black springs for identification purposes. However, the
problem was that the gun's strong airflow caused the paint to
scatter and adhere to the opposite side of the springs.
Lumina's ST-6R (φ1.0) automatic spray
gun, which has separate systems for piston air and for atomizing
air, the air for atomization was set to 0.05MPa (0.5kgf/cm2),
and the distance between springs and guns was set to 50mm. This
prevented paint from scattering and enabled clear markings to
In addition, the marked reduction in scattering
improved the work environment.
