Porosity is a major problem for diecasting engineers that impacts both component quality and functionality. It can lead to a host of defects, ranging from poor surface finish through to critical failures of pressure-tight components. Product integrity, performance and design reliability can be optimized if porosity can be controlled and managed effectively. One remedial process route centres on filling and sealing voids in castings through impregnation and a recent case study illustrates the benefits of deploying latest associated technologies from specialist UK firm, Ultraseal International Group, based in Coventry.
