Abstract
In a method for evaluation of abrasion of a forming mold, abrasion amounts of divided pieces which are divided from a mold piece constituting a cavity are measured with the divided pieces removed or not removed from a forming mold body. A layer, a marking-off line or satin is formed on the surfaces of the divided pieces, which are observed visually every predetermined shot to judge a degree of abrasion of the respective divided pieces.
