Description

The production process of borosilicate glass cups can be summarized into the following steps:

Raw Material Batching: First, select the appropriate raw materials, which usually include silica sand, boric acid, alkali metals, and a small amount of other additives, mixed in a certain ratio.

Melting: The well-proportioned raw materials are put into a high-temperature furnace for melting, where the temperature usually exceeds 1500°C.

Molding: The molten glass liquid is placed into pre-made molds or shaped using blowing techniques. This step requires precise temperature and time control to ensure product quality.

Annealing: After molding, the glass cups must be slowly cooled in an annealing oven to remove internal stress and prevent the finished product from cracking.

Inspection and Packaging: Finally, each glass cup undergoes a strict quality inspection, and after confirming there are no defects, they are packaged and then sent to the market.
