PROBLEM TO BE SOLVED: To provide a rubber or a synthetic resin-made molding which enables easy detection of debris by e.g. a magnet or an X-ray inspection instrument and its removal even when debris of the rubber or synthetic resin molding mixes with a food due to e.g. wear, allows color identification by each service site and is stable, without deterioration, to the heat during molding.SOLUTION: A molding contains a rubber or a synthetic resin, a pigment P dispersed in the rubber or synthetic resin and a ferromagnetic stainless powder S, and the pigment P is used to change the color of the molding by each service site of the molding, and the ferromagnetic stainless powder S is used to recover debris of the molding with a magnet. The place where the debris is produced can be identified by the color. The molding is used in a food processing plant. |
