Abstract
The method for manufacturing a hollow glass article comprises the following steps: introducing a blank (38) of the article into a finishing mold (26), and forming the article in the finishing mold (26), by injecting at least one gas and a forming pressure inside the blank (38) of the article. During formation of the article in the finishing mold (26), at least one gas injection point (54A) is displaced for directing the gas towards at least one predefined area of the blank (38), the gas being injected at least at a finishing pressure in order to form a specific inner glass distribution of the article.
Claims10
A method for manufacturing a hollow glass article, comprising the following steps:
- obtaining a blank of the hollow glass article in a blank mold,
- introducing said blank from the blank mold into a finishing mold, and
- forming the hollow glass article in the finishing mold, by injecting at least one gas at a forming pressure inside the blank,
- wherein, during forming of the hollow glass article in the finishing mold, at least one gas injection point is displaced in the finishing mold so as to direct the at least one gas towards at least one predefined area of the blank, the at least one gas being injected at least at one finishing pressure in order to form a specific inner glass distribution of the hollow glass article,
- wherein the at least one gas forms a recess or a raised portion in said at least one predefined area by varying a glass thickness between an internal wall and an external wall of said at least one predefined area.
A method for manufacturing a hollow glass article, comprising the following steps:
- obtaining a blank of the hollow glass article in a blank mold,
- introducing said blank from the blank mold into a finishing mold, and
- forming the hollow glass article in the finishing mold, by injecting at least one gas at a forming pressure inside the blank,
- wherein, during forming of the hollow glass article in the finishing mold, at least one gas injection point is displaced in the finishing mold so as to direct the at least one gas towards at least one predefined area of the blank, the at least one gas being injected at least at one finishing pressure in order to form a specific inner glass distribution of the hollow glass article,
- wherein, during forming of the hollow glass article in the finishing mold, said at least one gas injection point is displaced for directing the at least one gas towards certain discretely distributed areas of the blank, at least between a first gas injection position inside the blank and a second gas injection position inside the blank.
