The new Congress for intelligent Combining of Design, Casting, Computer Simulation, Checking and Cyclic Behavior for efficient Cast Components (C8) offers the opportunity to share experiences and knowledge in all of the disciplines involved in the product life cycle of cast components. The aim is to reach a shared understanding of the various requirements of effective and efficient cast products. Design and product development, structural durability, non-destructive component testing, foundry technology and simulation are on the agenda of this interdisciplinary congress for high-performance cast components. Papers focus on linking methods and competences from the various disciplines, with the aim of obtaining efficient, optimized cast components. Foundries, designers, users of cast components and experts in simulation, structural durability and non-destructive testing will benefit from this. The congress provides a view that goes beyond companies' own products and services, allowing consideration of other casting materials, new methods of component testing and dimensioning, and reliable designs optimized for lightweight construction.
