Blow & Blow Process
Details
Methods for Producing Glass Containers:
Blown Glass is also known as molded glass. In creating blown glass, gobs of heated glass from the furnace are directed to a molding machine and into the cavities where air is forced in to produce the neck and general container shape. Once they are shaped, they are then known as a Parison. There are two distinct forming processes to create the final container:- Blow & Blow Process - used for narrow containers where the parison is formed by compressed air
- Press & Blow Process- used for large diameter finish containers in which the parison is shaped by pressing the glass against the blank mold with the metal plunger
Blow and Blow Process - compressed air is used to form the gob into a parison, which establishes the neck finish and gives the gob a uniform shape. The parison is then flipped to the other side of the machine, and air is used to blow it into its desired shape.
