Abstract. Extrusions for various applications require properties only achievable with a modern high-pressure profile spray quench. One of the features of a modern extrusion quench is that the amount of cooling can be precisely controlled. Modulating the heat transfer coefficient allows response to the cooling requirements of a large variety of profiles. Using multiple nozzles with different flow rates in combination with modulating the water pressure provides the widest range of products can be quenched with one and the same equipment, while minimising distortion. This paper will introduce the patented Alpha Flex Technology. By using a two-cavity aluminium extrusion, different nozzles can be used in one nozzle stock increasing the range of the achievable heat transfer coefficients.
