Glass Pasteur Pipette

Melting of Glass Raw Materials
Workers will put a certain proportion of the configuration of the raw materials, which will also add a portion of broken glass, into a large high-temperature glass melting furnace for melting. In this process, the temperature of the furnace and the melting time need to be controlled to ensure that the glass raw materials are completely melted and the various components are evenly distributed.

Glass Molding
When the material melting is completed, it will reach the cutting mouth through the downstream channel.
Then the melting glass material will be directly dropped into the inner cavity of the mold, with the punch pressing, the glass cup will be initially shaped. When the glass material falls into the mold, the turntable keeps rotating. One mold after another will be turned to the exact place of downstream tunnel.

The production plateform will be fixed with one or several gas lances to keep the mold stay hot. The spray gun can be sintered in 360 degrees, so as to achieve the purpose of smoothness and no burr.

Annealing Process
After the polishing process, the robot takes the glass cup out, puts it on a conveyor belt. They will enter into a long annealing kiln, a process that prevents rapid cooling from breaking the glass surface or creating cracks. This slow cooling and annealing removes stress, improves stability and strength, and ensures the quality of the glass cup products.

Quality Inspection of Finished Glassware
When the glass passes through the annealing furnace, it comes to the quality inspection platform. In every production line, 3-4 people will be arranged to inspect the glass products as well as packing.
