\nNew Aquitaine, South West France. A land of vineyards, castles and – from now on – of fast, optimized and high-quality coating processes. Could Eurotherm have had a hand in this?<\/p>\n

The answer is yes, but let’s take a step back.<\/em><\/p>\n

\"tunnel<\/p>\n

The players involved in the project<\/h2>\n

It all began with Charente Pliage<\/u><\/a>, a company specializing in processing and coating metal components for architecture. The desire is to speed up processing times without compromising quality<\/strong>, particularly in terms of the products’ resistance to atmospheric agents. Charente Pliage’s first step was therefore to open a second production facility – Sud-Ouest Laquage<\/u><\/a>, in New Aquitaine – equipped with grit blasting, metallization and coating booths, as well as two polymerization ovens.<\/p>\n

Then came growth and an increasingly fast-paced market. Sud-Ouest Laquage needs to speed up the coating preparation phase<\/strong>. The decision is to integrate a tunnel for automatic pre-treatment into the plant.<\/p>\n

Industrie-Syst\u00e8mes<\/u><\/a>, Eurotherm’s partner since 2010 and supplier to Charente Pliage, contacted us to design and supply the tunnel.<\/p>\n

The very last players in the project are the French Aertech<\/u><\/a>, supplier of chemicals for pre-treatment, and the Italian Chemtec<\/u><\/a>, responsible for chemical formulations.<\/p>\n

\"tunnel<\/p>\n

A five-stage multi-metal pre-treatment tunnel<\/h2>\n

The pre-treatment tunnel would have to handle parts of different types, shapes, materials and sizes<\/strong> as effectively as possible: in particular, Sud-Ouest Laquage’s equipment is capable of handling parts with a surface area of up to 4 meters. The products generally require grit blasting or metallization, which give them anti-corrosive protection, however the company was looking for a solution that could also ensure other types of artifacts greater resistance to the aggression of atmospheric agents and corrosion.<\/p>\n

The tunnel was studied in collaboration with Industrie-Systemes, and truly is one of a kind. The same system is in fact capable of carrying out 2 different pre-treatment processes, to be selected depending on the material to be treated:<\/p>\n

    \n
  • The pre-treatment of steel and galvanized steel<\/strong> involves a phospho-degreasing or alkaline degreasing stage, followed by 3 rinses (2 with mains water and the last one with osmotized water and nanometer conversion).<\/li>\n
  • The pre-treatment of aluminum<\/strong> includes an initial acid pickling to remove oxides from welding and annealing, followed by the same 3 rinses.<\/li>\n<\/ul>\n

    Given the presence of different liquids, the tunnel was designed to minimize the risk of contamination between liquids during the different phases.<\/p>\n

    A final note. Chemtec took care of the liquid formulations based on its PRONORTEC system, a unique nanotechnological conversion that employs the chemistry of organic phosphorus compounds. The system is totally free of heavy metals, requires no rinsing, has a very long life and is simple to apply.

    The results of successful teamwork<\/h2>\n

    At Sud-Ouest Laquage, the new custom pre-treatment tunnel has brought nothing but benefits:<\/p>\n

      \n
    • Improved quality of the parts, with increasing paint adhesion on metal substrates<\/strong>.<\/li>\n
    • Improved quality of the work environment, as chemical pretreatment replaces traditional sanding.<\/li>\n
    • Reduced cost of the entire process.<\/li>\n
    • Minimization of energy and water consumption, as well as very low impact on the environment. The coating process can thus achieve the goals set by green and circular economy.<\/li>\n
    • Possibility of responding more quickly to the demands<\/strong> coming not only from the architectural sector – the company’s primary client – but also from the furniture and carpentry industries.<\/li>\n<\/ul>\n
