Die-cast head manufactured in aluminium alloy EN 44300 with very low copper
content. No visible screws. 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.
