Die-cast body and flange manufactured in EN 44300 aluminium alloy with very
low copper content. No visible screws. Subjected to galvanic anodizing
treatment divided into distinct phases: mechanical satin finishing, surface
degreasing, anodic oxidation and final sealing. The product is painted following
a continuous two step paint process (epoxy-based primer + polyester-based
colour finish), which allows to generate a single thick protective coating which
then generates aprotective barrier against atmospheric agents and UV rays.
Before fixing the diffuser on the Platek products a Pre-treatment using an
atmospheric pressure plasma process is carried out on the surface. The
process activates the ionic load on the surface exactly where it is needed, thus
promoting the best silicone grip possible and removing any residual release of
agents for a longer lasting seal. The next steps are the coating of silicone and
the assembly of the diffuser on the lighting fixture, with an automated process
to guarantee the perfect sealing of the lamp.
