Enclosure painting process at Pulsar takes place semi-automatically. The enclosures with properly prepared surface (free of dirt, dry and chemically protected against corrosion) are placed on a line in constant motion. Painting is performed automatically by moving arms of an industrial robot armed with a spray gun. The electrostatically charged powder reach successfully also the most inaccessible areas of the surface to be painted. The enclosures with applied powder are placed in an automatic tunnel oven, where after an appropriate heat treatment time, the surface acquires the appropriate properties, including colour or mechanical properties, depending on used paint. Powder coating is a popular finishing method for metal enclosures due to its durability and effectiveness.
