The casting clock is a frequently used means in metal and plastic foundry technology to visibly affix the date of manufacture and other information on workpieces . For this purpose, a surface structure similar to a clock is created on the workpiece by a marking system in an opening in the casting mold . With suitable positioning, this is easily visible later on the installed workpiece.

Traditionally, a whole series of castings is given the same marking; However, newer variants of the process also allow each individual item to be marked individually.

For example, the actual production time of a car can often be estimated using matching casting clocks on built-in plastic parts such as fuse cover caps or glove box covers.
