Product cooling and static removal

To cater for multi impression closure moulding where typically 120 caps can be moulded on a 10 second cycle it is imperative to cool them down to avoid deflection in the collection bin but there is another major advantage in quickly removing heat from the product and that is to further reduce the cycle time so UPM Conveyors have developed a range of conveyors incorporating high air flow fans mounted over a water cooled heat exchanger as shown in the photograph.

Cold air is blown onto the closures to typically reduce the temperature from 70 C to 20C and as standard variable speed control is available to regulate the time product remains under the air flow. Also UPM have fitted air ionisers at the discharge area to remove static with the result that one major closure manufacturer has seen a production increase of 38% with a payback time of only 3 months.
