Extruded aluminium alloy body. Die-cast trim and base manufactured in
aluminium alloy EN 44300 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.
