摘要 |
<p>A method of manufacturing fuel tanks made of polymer material using a blow molding technique, the method including: offering up at least one sheet form extrudate between two opposing cavities of an open mold with an impression that corresponds to a shape of a tank that is to manufactured; then bringing the two cavities together until the mold is closed; as the two cavities are being moved closer together and before the extrudate comes into contact with one of them, injecting a first fluid between the extrudate and at least one cavity; injecting a second fluid on the opposite side of the extrudate from each cavity, to press it firmly against the wall of the cavity; removing the first fluid present between the cavity and the extrudate before end of injection of the second fluid.</p> |
