Abstract
The present invention refers to an arrangement for the production of blow-molded hollow bodies from plastic with a blow molding machine, wherein a cooling medium can be blown via a conduit into a blow mold respectively into the hollow body for blowing up and cooling of the blow-molded hollow body. For improvement of cooling the interior of the hollow body within the blow mold, a closed conduit system is provided, in which the cooling medium circulates and is kept at an elevated pressure level and is cooled by means of a heat exchanger. Thereby, a higher yield of piece per time is realized at lower production cost. The closed cooling medium circulation system can be essentially retrofitted to all blow molding machine in order to raise efficiency.
