April 29th 2016- Custom Temperature Control Units Speed Cooling Cycle, Maintain High Quality
 
Delta T Systems was contacted by a customer in the blow molding industry to design a custom temperature control unit to cool the molds in their production equipment.
 
blow molding temperature controlBlow molding, a manufacturing process which forms hollow plastic parts, consists of three main types: extrusion, injection, and injection stretch. The blow molding process begins by melting down the plastic and forming it into a parison, a tube-like piece of plastic with a hole in one end. The parison is clamped into a mold and compressed air is blown into it until the plastic fills the mold. Once the plastic has cooled and hardened, the mold opens up and the part is ejected.

Temperature control units, like Delta T Systems,’ are used in blow molding applications to cool the process molds. Molds must be cooled quickly to maintain a high quality product and to increase part production output.

Delta T Systems designed a custom unit for the customer that circulates 268 gallons of water per minute through the mold, maintaining a consistent temperature of 37 degrees Fahrenheit using an air actuated modulating valve. A central chilling system is used to  cool the process water. To avoid condensation, all of the piping of the custom temperature control unit is insulated with elastomeric closed-cell foam.
