Manufacturing Process of Glass Funnel
Tube Feeding
Clear or amber, the tubes are made of neutral borosilicate neutral glass with high degree of Hydrolytic Resistance. Tubes are loaded by a robot on a rotative machine.
Forming
The tubes are heated, shaped and cut to give the dimensional parameters in 3 main steps:
Shoulders and neck forming (including 100% on-line dimensional inspection).
Tubes parting: Heating and cutting to set vial height.
Bottom glazing: Heating, glazing and cooling.
After forming
Vials are cooled down and blown with filtered air 100% on-line inspections of:
Total length and bottom concavity by electromechanical gauge. Internal neck diameter by camera.
Annealing
Vials are individually picked and placed on the conveyor belt of the annealing lehr with no glass to glass contact. Perfect annealing to release residual stresses through a monitored thermal cycle.
Final inspection and packing
Final inspection under clean room conditions.
Optional cosmetic inspection by off line camera.
Vials are packed in shrink-wrapped PP trays or in cleanpacks and then palettized.
Raw Materials and Ingredients Processing of Glass Funnel
When manufacturing glassware or glass containers, crushed or recycled glass, or cullet, is an additional key ingredient. The amount of cullet used in the batch house of glass varies. And the manufacturing process of the glass container or glassware is a continuous process, so the batching processes will also occur constantly.
The raw materials of soda lime glass will be then gravity fed into the weighing and mixing area, and finally elevated into batch hoppers that supply the glass furnaces. Sometimes the conveyor belt consists of a magnet that will remove the magnetic materials to ensure the composition of the material will be the same for all the processes. Cullet melts at a lower temperature which reduces energy consumption and requires fewer raw materials.
