EXAMPLE CASTING PATTERN
PATTERNS ARE USED TO CREATE THE SHAPE IN THE SAND, INTO WHICH MOLTEN METAL WILL BE POURED TO BECOME THE CASTING.
Patterns can be made from metal, wood or plastic. Most patterns are made from aluminum, called match-plates and have a long life before wearing out. Wooden patterns can be used provided the quantities are low and the wall thickness fairly substantial. A casting pattern is a replica of the object to be cast, used to prepare the cavity into which molten material will be poured during the casting process. Patterns are made to exacting standards of construction, according to the quality grade of the pattern being built, and so that they will repeatably provide a dimensionally acceptable casting.
