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.
Claims15
A method for manufacturing a hollow glass article, method wherein:
- a blank of the article is introduced into a finishing mold, and
- the article is formed in the finishing mold, by a injecting at least one gas at a forming pressure inside the blank of the article,
- wherein, during formation of the article in the finishing mold, at least one gas injection point is displaced so as to direct the gas towards at least one predefined area of the blank, the gas being injected at least at one finishing pressure in order to form a specific inner glass distribution of the article.
A facility for manufacturing a hollow glass article, said facility comprising:
- means for introducing a blank of the article into an imprint of a finishing mold, and
- means for forming the article in the finishing mold, is said forming means being able to inject at least one gas at a forming pressure inside the blank of the article,
- wherein the forming means comprise means for displacing at least one gas injection point, the displacement means being able to direct the gas is at least one predefined area of the blank, the gas being injected at least at a finishing pressure so as to form a specific inner glass distribution of the article.
