Abstract: A method and device for producing an optimized neck contour on preforms below the neck which is optimal for subsequent stretch blow molding. The geometry has a significantly thinner wall thickness than the neck itself. The preform can only be produced in the injection molding tool, when axial channels are used on the point or the vanes produce the thin points on the preform during injection molding. The thin-walled geometry on the preform can be produced outside of the mold during post-cooling by embossing. The preform is then removed in a cooled receiving sleeve and is cooled in the body by intensive contact cooling while no cooling contact is made with the preform neck due to the initial position of the embossing element. Due to the reheating of the neck they can be mechanically deformed into a new geometry advantageous for blow molding and thus wall thickness can be influenced.

Abstract: A device and a method for producing a preform having a shoulder and base geometry optimized for subsequent stretch blow molding, since the preform cannot be produced according to the conventional injection-molding method. For this purpose, the preform produced in the injection-molding tool is transferred into a conditioning station and is conditioned and cooled in the shaft while no contact is made with the top of the preform and the preform shoulder on account of a special contour of the conditioning receptacle. Due to the reheating of these preform regions they can be mechanically deformed into a new geometry which is advantageous for the blow molding process and thus their wall thickness can also be influenced. In the subsequent blow molding process the deformed preform has the advantage that the plastic material which is distributed better in the bottle results in considerable material savings and higher quality bottles.

Abstract: The present invention relates to a method and a device for producing a preform with a base geometry optimized for the subsequent stretch blow molding. The preform produced in the injection mold is removed in a cooled removal sleeve and cooled in the shaft by intensive contact cooling, while to the greatest extent no cooling contact is made with the domed preform end due to a special contour of the cooling sleeve. On account of the re-heating of this domed end that is possible as a result, the latter can be mechanically deformed into a new geometry that is more advantageous for the blow-molding process, and consequently also influenced in the wall thickness. In the subsequent blow-molding process, such a deformed preform has primarily the advantage that the polymer material distributed better in the bottle can lead to considerable material savings and to bottle bases of a higher quality.
