Abstract: A measuring device includes: a support which supports a measurement target object; a furnace which heats the measurement target object; an elevating mechanism which moves the furnace; and an electronic balance which measures the weight of the measurement target object, the elevating mechanism moving the furnace so that the measurement target object which is supported by the support is housed in the furnace.

Abstract: A management system includes: a tag given to structures including at least one of a pattern, a molding board, and a molding flask; a storage device; and a control device, wherein the control device is configured to store, in the storage device, collected data and management information being associated with each other, and when a predetermined condition is met in a case where the mold is transferred from a first position to a second position, associate the collected data with management information at the second position based on the information read from the tag, and the predetermined condition is met when the mold having been transferred to the first position along with the structure given the tag is not transferred to the second position along with the structure given the tag, or when the mold is combined with the structure given the tag at the second position.
