Blow Air Cooling

Extrusion blow molding with chilled compressed air

Cooling the product is the longest and most critical part of the solidification process. The fact that the mold only removes heat from the outside surface of the container causes material stress and extended cooling time in the mold.

Blue Air Systems’ Blow Air Cooling units replace the regular blowing air with chilled compressed air inside the container during the blowing process. As a result the heat is removed also from the inner surface of the container reducing material stress and cutting cooling time up to 50 %. Blue Air’s Blow Air Cooling-System stands for important contribution to increased production and improved quality in the field of extrusion blow molding.
