Casting Alloy & Process Selector Engineered Casting Solutions in conjunction with the American Foundry Society (AFS) and Product Development & Analysis (PDA) have developed a Casting Alloy and Process Selector (CAPS) tool to help casting buyers and designers determine which casting alloys and process(es) may be suitable for their specific metal casting designs. All you need to do is enter basic data about the metal casting (if available, alloy, weight, wall thicknesses, surface finish, production volume) and various processes will be presented to you. The information contained in CAPS are estimates of industry averages and can not be considered absolutes.  Every manufacturing facility offers different capabilities. For specific information, you must contact your metal casting suppliers. To access CAPS, click here .
