2019-1-5  Pattern making is an art in itself, which requires a a lot of patience and hard work. In metal casting, patterns are used to create the sand molds. They are placed inside one half of a flask and then they have the tempered sand packed around it. When the pattern is taken out from the sand, it leaves an exact impression.
