1、Raw Material Preparation:

The manufacturing process begins with the collection of raw materials such as silica sand, soda ash, limestone, and cullet (recycled glass).

These raw materials are carefully measured and mixed in precise proportions to create the glass batch.

2、Melting:

The glass batch is fed into a furnace where it undergoes high-temperature melting, typically ranging from 1400°C to 1600°C.

In the furnace, the raw materials fuse together to form molten glass, which is then homogenized to ensure uniform composition.

3、Annealing:

Once formed, the glass bottles pass through an annealing lehr, which is a long oven with a carefully controlled temperature gradient.

Annealing relieves internal stresses in the glass, making the bottles more durable and resistant to breakage.
