Extruded aluminium alloy body and side shoulders. Die-cast head and flange
manufactured in aluminium alloy EN 44300 with very low copper content and
aluminium alloy ground fixing flange. Fully concealed ground fixing flange. As
an alternative to the traditional polycarbonate (PC),used with diffusers to seal
the lamp polymethylmethacrylate (PMMA) is used , so we obtain characteristics
of high transparency, UV resistance and scratch resistance. A4 Stainless steel
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.
