12 PART BUYERS A U T H R I T Y Digital Casting (DC) is the integration of computer driven technologies to manufacture quick and cost-effective castings. Partnering with an integrated DC service provider who offers a full complement of DC technologies is critical. Oftentimes DC technologies are piecemealed by using multiple vendors, which ultimately can lengthen leadtimes, add costs and cause headaches. Specifically, DC is the application of both general manufacturing and foundry specific technologies, listed below, to make a casting. • Solid Modeling • Fluid Flow Simulation • Solidification Simulation • 3D Printing • Laser Metrology SOLID MODELING The foundation of a DC is supported by a Computer Aided Design (CAD) solid model. In a generic sense, a solid model is a 3-dimensional computer representation of an object. In the casting world, a skilled engineer uses CAD software to build a dimensionally precise 3D representation of a casting. Without a solid model it is impossible for the casting manufacturer to apply any digitally based manufacturing and/or foundry technology. FLUID FLOW SIMULATION Foundry simulation, specifically fluid flow and solidification simulation is used to ensure that DC’s are made quickly and cost effectively. Fluid flow simulation calculates how molten metal flows into the mold cavity. From this analysis, a foundry engineer can measure metal velocity, temperature and pressure. Knowing this information allows the engineer to optimize casting manufacturing methods and minimize the potential for casting defects.
