摘要: In a method for molding glass products having fine structure as of an optical fiber holder with high size precision, mold used the has in such that difference occurring when product is cooled down to room temperature where at end pressure and formed by transfer are same one another so adjusted completed falls within permissive precision range. The may satisfying, temperature, formula [1+(αg-αm)×ΔT+αg'×ΔT']×Sg, wherein Sg denotes thc temperature; αg mean thermal expansion coefficient be molded range from transition molded; αm ΔT between ΔT' which mold's exerted released case higher than after pressing pressure; αg' summation sag temperature.
