4C-Technologies supports customers all over the world with knowledge around using lightweight metals in their products. 4C-Technologies are specialists in the casting technology of these materials and supports customers to optimize the design of a product not only for the usability but also for a problem free production of the product. To optimize a product for the casting process, eg. gravity casting or high pressure die casting, it is often crucial to make CFD simulations of the product to get the desired quality and problem free production. These CFD simulations provide information of all thinkable problems like cold flows, internal porosities, erosion of the production tools, venting problems, etc.
