Different Types of Pattern
→ In casting process, Pattern is the replica of the device which is the output of casting process. This when molded in sand forms mold. After filling mold with the molten metal there is a formation of casting. Patterns play a very important role in casting as they decide the quality as well as perfection in a particular casting process. Gates and runners are the most important components in several types of pattern. Pattern is the basic requirement for creation of mold and it is always bigger than the size of casting. There should be a proper selection of pattern …
