Unload Station and pass to Quality Control Station
As the first stage in the specialized UniShield16 coating journey, each fixture receives an exhaustive surface refinement treatment.
Utilizing a fully automatic high-pressure sand-blasting chamber ensures that all fixtures are thoroughly prepared to provide a highly reliable, consistent, and durable finish.
At the initial pretreatment stage, close attention is paid to completely removing all dirtparticles, oil, and other foreign contaminants.
Reverse osmosis is a water purification process that uses a semipermeable membrane to remove impurities, contaminants, and unwanted substances. Rinsing RO water through 5 stations ensures that the luminaires are thoroughly cleaned to provide a superior-quality product that meets the highest standards of performance and aesthetics.
The zirconium-based surface conversion comprises Nano-Ceramics and is free of nickel, phosphates, VOCs, and regulated chemicals.
Applying De-Ionised water in the upcoming stage to provide stability, purity, and sanitation as a processing element before passing along to the heart of our surface conversion stage, "Nano-Ceramic coating".
A dry finishing process that uses finely ground particles of pigment and resin that are electrostatically charged and sprayed onto electrically grounded parts.
The charged powder particles form a powerful surface bond area and are held until melted and fused into a uniform coating in a curing oven.
Specially formulated epoxy-polyester resin-based is applied as a primer coat on aluminium alloys. The coating enhances the corrosion resistance property of aluminium when exposed to severe climatic conditions like coastal and snowy areas.
It also helps reduce blistering and other surface defects that may occur during the curing process.
At this stage, the primer is partially cured to gain excellent inter-coating adhesion with the top coat.
The final top coat process combines protective properties with excellent weather resistance with a long-lasting exterior grade Polyester powder with UV-Stabilised additives, giving exceptional color rendering on the products' surfaces.
The painting line is fully equipped with both automatic and manual machine guns.
In the final process of the 16 stages, the cure oven provides heat to promote chemical reactions that result in a hardened, durable, and fully cured coating.
Ensuring the coating surface is second to none with several tests.
