Die-cast head manufactured in aluminium alloy EN 44300 with very low copper
content. No visible screws. Microcast flange in AISI 316L. GORE® valve to
prevent condensation. 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.
