Document Summary
Castings provide for e cient and economic geometric complexity. Ceramic (such as sand) pour aluminum? ceramic or steel. Essentially anything that will not melt or be damaged with the liquid material. Parting line when the mold is allowed to split in half so the part can be removed. Draft, a taper inside of the mold to help the part slide and separate from the mold. Holes are made with the use of cores. This is the most productive method of green sand casting today. In green sand, clay and water adhere the sand grains to each other. mud (clay + water) is pliable, relatively soft, rough surfaces. Glue the sand together with chemical adhesives rather than mud (clay + water) Stronger than green sand and used to make cores and sometimes molds. Liquid resin + liquid catalyst mixed with sand and they harden as they react (aka no bake or air set)
