Extrusions of up to 7 metres long, even flexible polyamide types are automatically transferred to the vertical plane. They are then taken into a fully computerised, ten stage chemical pre-treatment tunnel.
There they are cleaned, etched and chromated by a synchronised spray system. They then pass through a rinse section that uses an impressive 10,000 litres of pure de-mineralised water every hour! Every stage of this process is computer controlled to ensure the high standard of quality you expect from Vertik-al. The extrusions then pass through the dry off prior to powder coating. Temperature in this section of the process is also computer controlled, ensuring metal temperature stays within set parameters.
The heat exchange system within this section also ensures the atmosphere is not contaminated and the extrusions arrive at the coating stage in a consistent, clinically clean dry condition.
Coating the extrusions is as revolutionary as the first process – the coating thickness is controlled to extremely close tolerances over the 7 metre length. This ensures consistent quality extrusion after extrusion! The coating is then cured, not in a conventional oven, but in a micro chip controlled environment, again completely free from contaminates.
To compliment the Vertik-Al plant, we have three conveyorised horizontal coating lines using quick change colour speeder booths, which enables change times to be reduced to around 5 minutes. This offers the very best quality and turnaround for smaller batches.
Extrusions, pressings and virtually any type of aluminium fabrications are pre-treated through a nine stage immersion process, dried by controlled hot air before being loaded onto the powder coating lines. Items can be coated both manually or automatically using reciprocating guns and then transported through a Qualicoat approved curing oven.
Whichever way you choose – we at Vertik-al use the very latest technology available for horizontal and vertical coating – giving you the customer the very best finish available, as you would expect from the market leader in powder coating.
We love what we do and it shows. There’s no challenge too big or too small, and we dedicate our utmost energy to every project we take on.
Most parts are suitable for horizontal powder coating limited by the size of the booth.
Florida testing – ‘Q-Lab’ Florida climate combines:
Florida testing consists of observing colour variation and gloss change in time. Florida natural exposure is a universal testing procedure.
The QUALICOAT specification defines four classes of powder with increasing levels of weathering durability:
The QUALICOAT specification defines three values for powder coating finish gloss levels when tested to ISO 2813 using an incident of light at 60° to the normal:
