![]() ![]() The mixture is then fed to the fore hearth where it is cooled about 2200℉ where it gains the consistency of honey. At this step temperature, consistency and time are precisely monitored to make the defect-free final product. This molten glass is then passed through the furnace throat into the refiner at about 2350 ℉. Air bubbles in this molten liquid are allow passing as they can lead to the defective final product. ![]() The temperature of the furnaces is marinated at peak temperature for consecutive 3-4 hours thus ensuring melting of all the mixture. To assure fuel efficiency, air and fuel proportion is monitored regularly. The furnace operates at a temperature of 2850F (hotter than molten lava) round the clock to melt the mixture in batch producing the viscous mass. The continuous feed to the furnace is done by the belt conveyer. The interior of the furnace used for melting is made up of silica-based refractories that will remove any chance of contamination. Batch is then transfer to large and complex glass furnace at a regulated rate through feed hoppers ![]() Precise weight and measurement of each batch plays a crucial role in the quality of the final product. This is done by advance grinding machines and mixing machine as uniform mixture is very important for the batch. It is a necessary step as it makes glass bottle manufacturing process environmental friendly.Īmong other raw materials are barium sulphate, dolomite, zinc oxide, potassium carbonate, feldspar, boric acid and sodium sulphate, All the raw materials are taken into the exact proportions required to produce the best quality glass bottles.Īll the ingredients are finely powdered and thoroughly mixed into a batch. It is recycled and furnace-ready glass and depending upon glass type, it is 5 to 50% of the batch. It also acts as a fluxing agent in the process and improves durability as well as chemical resistance of glass bottles. It is used as a flux to reduce the melting temperature of silica to make it transform at comparatively lower temperatures. It imparts hardness, brittleness, chemical stability and wear-resistance to the glass bottle. Main raw materials for the manufacturing of glass liquor bottle are All the quality control measures are assured in this step to produce high quality and maximum lifetime molds. Design consultancy and support is mandatory in mould making process. Special engraving machines with unparalleled expertise are used to make exquisite engravings. Highly advance machines like “Computer Numerical Control (CNC)” with cutting-edge technologies are used for this step. Mold for glass bottle is made from high quality cast iron or bronze alloys. Due to its significance, it is done by technical documentation and accurate mold construction drawings. Mold making is the most important step in glass bottle manufacturing process as it is responsible for the final shape or design of the glass bottle. Once designed drawing is made by glass bottle manufacturing experts, it is make sure that glass bottle is engineered to exact specifications. The first and foremost step in glass liquor bottle manufacturing process is the design of the glass bottle depending on the type of liquor/brand. Steps of glass liquor bottle manufacturing process are briefly described as follows. It requires years of excellence, continuous improvement and various production techniques to make a high quality glass bottle. Glass liquor bottle manufacturing is an art of creativity and it is not a simple process as it involves scientific techniques and advance technologies under the supervision of glass liquor bottle manufacturing experts and technicians. Glass liquor bottle manufacturing process dates back to 5000 years old tradition while in the modern world it is all automated process. Glass bottle is preferred as it protects the flavor of the liquor from the first till the last sip. Glass bottle is one of the most recommended packaging material for liquor or other beverages due to its ability to be recycled making it environmentally friendly as well. ![]()
