Accordingly, unless otherwise indicated, features of the various embodiments may be additionally combined, separated, interchanged, and/or rearranged without departing from the technical concept of the present disclosure.
The use of cross-hatching and/or shading in the drawings is generally used to clarify the boundaries between adjacent components. As such, unless otherwise noted, the presence or absence of cross-hatching or shading does not convey or indicate any preference or requirement for a particular material, material property, size, proportion, commonality between the illustrated components and/or any other characteristic, attribute, property, etc., of a component. Further, in the drawings, the size and relative sizes of components may be exaggerated for clarity and/or descriptive purposes. While example embodiments may be practiced differently, the specific process sequence may be performed in a different order than that described. For example, two processes described consecutively may be performed substantially simultaneously or in reverse order to that described. In addition, like reference numerals denote like parts.
When an element is referred to as being "on" or "on," "connected to" or "coupled to" another element, it can be directly on, connected or coupled to the other element or intervening elements may be present. However, when an element is referred to as being "directly on," "directly connected to" or "directly coupled to" another element, there are no intervening elements present.

rotating the glass article and setting a mold to a predetermined position, the mold having a molding surface of a set shape;
continuously heating the glass product to enable the temperature of the glass product to be in a preset temperature or a preset temperature range; and
blowing air into the interior of the glass product,
wherein the outer surface of the rotated glass article is in frictional contact with the molding surface of the mold, and the glass article is made into a glass article having a predetermined shape by the frictional contact.
2. The glass blow molding method according to claim 1, wherein the glass article is rotated at a constant speed or at variable speeds.
3. The glass blow molding method according to claim 1 or 2, wherein the glass article is a glass tube.
4. The glass blow molding method according to claim 1 or 2, wherein the mold is fixed to one or any of a plurality of the predetermined positions.
5. The glass blow molding method according to claim 4, wherein the molding surface of the mold contacts a portion of an outer surface of the rotating glass article, and the molding surface of the mold having the set shape is one end surface of the mold.
6. The glass blow molding method according to claim 5, wherein the molding surface of the mold having the set shape is a smooth surface.
7. The glass blow molding method according to claim 4, wherein the frictional contact between the outer surface of the glass article and the molding surface of the mold is a sliding frictional contact.
8. The glass blow molding method according to claim 1 or 2, wherein the mold is provided to be rotatable around an axis portion, and the frictional contact of the outer surface of the glass article with the molding surface of the mold is rolling frictional contact.
9. The glass blow molding method according to claim 8, wherein the rotation of the mold about the shaft portion is a passive rotation that follows the rotation of the glass article.
10. The glass blow molding method according to claim 8, wherein the rotation of the mold about the shaft portion is an active rotation.
