A word from ODYSSEE

The challenge was to maintain the effectiveness of aluminum molds used to form plastic bottles. The molds, which were cooled using water, displayed signs of corrosion, calling the long-term reliability of the production chain into question, with all of the economic issues that this entailed.


ODYSSEE replaced the water treatment used in the system, which was initially based on polyphosphonates and alkalizing amines, with ODYTHERM FS500. This change made it possible to achieve the goal of controlling corrosion on the molds, which improved their reliability over time and contributed to an effective pace of production at the sites.

Client challenge

The cooling of aluminum molds has always been a major challenge, not only in economic terms (a mold costs between €10K and €100K), but also as regards its technical aspects.

The injection of plastic to make water bottles pursues a goal of excellence that is vital in order to handle increasingly impressive production rates.

Mold corrosion remains a major problem that the entire sector must consider.

ODYSSEE’s solution

ODYTHERM FS500

ODYSSEE Environnement set up a battery of tests in its lab before suggesting the use of ODYTHERM FS500.

The inhibitors used in ODYTHERM FS 500’s formulation protect the walls through the absorption of a monomolecular film, which makes it possible to avoid any contact between the water and the metal surfaces of the system, without disrupting the heat exchanges.

ODYTHERM FS500 is perfectly suited to closed circuits that contain sections made of aluminum or aluminum alloy, buffering the pH at 7.2 to 8.2.
