The difference between the process of pressing glasses and mechanism glass bottles

In the production process of glass containers, there are two processes of pressing glass bottles and producing lines to produce glass containers.

What kinds of glass containers and processes are suitable for these two production methods. The process of pressing the glass is that the inner wall of the container must be straight up and down, there is no curved portion, and the outer portion can be irregular or engraved, and the handle can be added.

  The production process is that the glass liquid mass directly enters the molding die from the feed chute, the pressing punch presses directly under the action of the air pressure, and then the molding die is opened (there is an artificial die opening and the robot hand automatically opens the die, etc.) and the labor or machine is used. The bottle clamp clamps the glass into the baking turntable, and after baking, it enters into the annealing furnace for secondary annealing, and then it can be tested and packaged.

The assembly line glass bottle process is a pressure blowing method. It can be blown into a glass container whose diameter is greater than the diameter of the bottle mouth. After two blows, the machine structure is more complicated than pressing.

The liquid mass of glass frit falls into the blank mold through the trough, and after the air is blown by the air head, it forms a blank bottle, which is turned into a molding die after being knocked over by a die bottle, and then the air blow head is pressed twice to form a complete Glass bottle shape,

It is sent to the secondary annealing furnace through the conveyor belt for annealing, and then it can be checked for packaging.
