Production Process

Our efficient production process ensures high-quality aluminium profiles.

We carefully design for performance, durability, and aesthetic appeal whilst adhering to stringent environmental and sustainability standards.

Extruding

The billet (aluminium alloy as raw material) enters an oven with temperatures of 400-500 οC, is cut and pressed mechanically in the extrusion press passing through dies (moulds) to form the various profiles.

Then the profiles are cut to the desired length and put in the aging oven (180 οC for 5-7 hours) to obtain the required hardness.

The resulting solid leftovers (pieces and aluminium chips) will be collected in containers and sent for recycling.

Powder coating

The profiles are loaded (hanged vertically) on hooks and chemically treated in cascade baths. Each bath is followed by a water rinse. The overflows of these bathrooms will be led through special channels to the wastewater treatment plant for neutralization and disposal.

Next is passivation (chrome-free chemical coating of profiles for effective adhesion of powder) and polyester powder coating (TGIC-free). Special cyclones operate in the paint chamber with a powder absorption and recovery.

At the end of painting the profiles are placed in an oven for powder polymerization at 180-220 οC for 25-40 minutes (according to the instructions of the powder supplier) and then they are ready for packaging and delivery.

Anodizing

In this surface treatment method, aluminium profiles are loaded into bars (aluminium crates) and go through a series of electrolytic and chemical treatments inside specially designed tanks.

Each chemical treatment bath is followed by one or more rinsing baths with water. In this way, the surface of the aluminium profiles is cleaned and prepared to be anodized, i.e. to create a layer of aluminium oxide on the surface for protection against oxidation.

Towards the end of the process the profiles are rinsed with deionized water and sealed to protect the anodic coating. The bars are moved (lifting, moving, immersing) with the help of automated gantry cranes. They are then transported to the unloading stations for removal of the aluminium profiles from the crates and packing for placing on the market.
