Influence Of Die Temperature On Adhesion Of The Paints On Die Casted Aluminium Parts: A Case History

The Companies that paint casted parts, are often in trouble with paint adhesion problems. These problems arise often randomly, making it very difficult to keep them under control. Recently, with new mild eco-treatments of cleaning and pickling, the problems became even more difficult to solve. In this work we have shown that other parameters, affecting paint adhesion, have to be taken into account. The die surface temperature and other variables play a capital role in the adhesion of paints and coats. The authors disclose a case history and assume some hypothesis of possible mechanisms to explain the influence of die surface temperature on paint adhesion. Besides that, will be given suitable industrial solutions also exploiting a new technology based on infrared devices applied on-process and suggestions around new further investigations to be carried out on the other parameters
