摘要:
Disclosed is a method for preparation of a glass forming mold having a layer of a lubricating mold-releasing agent with reduced fluctuation in lubricating property, by baking the layer of the lubricating mold-releasing agent in a manner that prevents defects like blistering or peeling of the layer, or surface roughening. The method is a method for preparation of a glass forming mold having a baked layer of a lubricating mold-releasing agent on the mold surface thereof, wherein the method comprises heating the mold surface with an applied lubricating mold-releasing agent thereon by exposing the mold surface to a high frequency magnetic flux until the temperature of the mold surface reaches a predetermined baking temperature.
