Abstract

A method for drying workpieces includes immersing the workpieces in a liquid bath, raising the workpieces with a first holder until a central opening of the workpieces is visible above liquid surface, then using a dry second holder rod inserted through said central opening to continue raising process. Due to this, a drying portion of the workpiece is not held by a wet holding mechanism.
