Glass making process
Glass manufacturing process
At Vidrala we take care of the smallest detail throughout the entire glass manufacturing process. We select the best raw materials to obtain glass, committed to sustainability and care for the environment, and we carry out the melting, moulding, annealing, inspection and dispatch, guaranteeing the highest quality in all our manufacturing lines. A process that allows us to work efficiently and competitively, so that our glass products reach the customer in the best conditions.
See all the details in this video, from how glass is made to glass bottle production process.
Step 1
Raw materials
The main components of glass come from nature.
- Silica sand
- Sodium carbonate
- Limestone
- Recycled Glass
Step 2
Merging
The mixture is melted in furnaces at a temperature of around 1,500ºC, converting the mixture of raw materials into molten glass.
When it comes out of the kiln, it is cut into molten glass "drops" of a certain weight.
Step 3
Mould
The glass droplets are placed in moulds where they are blown into the desired container shape.
Step 4
Annealing chest
To ensure the solidity of the glass containers, they are placed in an annealing chest where they are cooled in a slow and controlled manner.
Step 5
Quality control
Every single pack is subjected to strict automated quality controls. Defective glass packaging is melted again in the furnace.
Step 6
Paletising
The glass packages are palletised and hermetically sealed so that they reach the customer in the best possible condition.
Step 7
Shipping
The glass packages are palletised and hermetically sealed so that they reach the customer in the best possible condition.
