The questioner didn't say where this Moulder lived. In Britain he would be a Moulder, in the US a Molder (spelling change). In either case he made molds. Used for casting iron, brass etc, also in potteries and probably other industries. Still a skilled occupation that's around today

Also could have to do with printing
