Die-cast body and flange made of aluminium alloy with very low copper
content. A4 Stainless steel screws. Graduated ferrule in AISI 304 stainless
steel with double locking system for safe positioning. GORE® valve to prevent
condensing. 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.
