Glass bottle products are used in more and more places in life, such as perfume glass bottles, aromatherapy glass bottles, essential oil bottles, cosmetics, etc.
The manufacturing process involves several steps that gradually result in an amazing product. These steps include:
1.Premium Material Preparation
The premium raw materials used by most manufactures include sand, soda ash, limestone and cullet. Sand is gives the glass strength once made. It also produces silica which is used as a refractory material. It resists decomposition by heat and retains strength and shape at high temperatures. Soda ash is used as a flux to lower the melting point of silica. While cullet is used to make glass recycling possible.
2. Batch processing
Batching consists of mixing all raw materials in a hopper then unloading them into the furnace. Material is unloaded in batches to ensure that the composition mixed is the same for all products. This process is done using a belt conveyor that contains magnets to remove iron and avoid contamination.
3.Melting Process
The batches fed into the furnace are burned at high temperatures of 1400 degrees Celsius to 1600 degrees Celsius. This allows for the raw materials to be melted into a gooey mass
4.Forming Process
This process involves 2 different methods to obtain the final product. You can use Blow and Blow(BB) or Press and Blow(PB). In the BB process, perfume bottles are made by blowing compressed air or other gases. While PB involves using a physical plunger to press a gob of glass to form parison and blank molds. The blank mould is then blown to obtain the final container shape.
5.Annealing Process
When the container is formed, it is cooled to a temperature at which atoms can move freely without breaking the dimensions of the glass vessel. This is to ensure the consistency of the material and prevent spontaneous breakage.
