DMR030392 PATENT 0230M Dkt. No. 91A426 Abstract An article is formed in a mold by blowing a hot plastic material with a blowing gas. A cooling fluid is introduced into the article to cool the article and allow its removal from the mold. A warmed gaseous form of a cryogen is added to a pressurized liquid form of the cryogen to form the cooling fluid by introducing the pressurized form of the cryogen into a jet pump and drawing the warmed gaseous form of the cryogen in the pressurized liquid form of the cryogen. The resultant cooling fluid circulates through the article by being introduced into the article and discharged from the article by two or more blow pins. Part of the discharged cooling fluid is then recovered in a storage tank. The cooling fluid, which after cooling the article is composed of the warmed gaseous form of the cryogen, is then drawn from the storage tank into the jet pump during formation of the cooling fluid. Additionally, the blowing gas can comprise cooling fluid formed in the manner outlined above. Alternatively, the blowing gas can comprise the warmed gaseous form of the cryogen recovered from the article.
