facility is located in a growing region of Xuzhou, China, and manufactures more than 400,000 glass bottles per day. Based on the modern bottling factory and experienced know-how team, our bottle production is intended for the premium end of the beverage, food and cosmetic industry.
the foremost advantage of stocking a huge amount of molds in-house is the flexibility. One factory can hardly meet all your requirements.
React to market quickly. Our bulk production allows businesses to move through production phases quickly and easily.
Lower cost when producing in low volumes. Roetell's production lines function diverse bottle production simultaneously.
Raw materials that we primarily use in the manufacture of glass bottles are sand, soda ash, limestone and cullet.
The glass bottle and jar production is a continuous process. The batching is done continuously to feed the furnace by belt conveyer since the furnace beginning.
Raw materials are proportionally fed into the hopers, mixed, and then unloaded and transferred to the furnace. The mix of raw materials will be added to the furnace like a batch. In this phase, we make sure the composition of the mix is the same for all the products.
During the melting stage, the raw materials are heated at the temperature of 1600℃ and melted into a viscous mass. The mold temperature is automatically regulated by our software and integrated control room at any given moment. The process starts with water evaporation, followed by the burn-off of organic matters and silica transformation, and then the composition begins to melt.
After melting, the molten glass is cooled to lower temperature to make the viscous condition.
Two basic principles of formation are used in manufacture: Blow and Blow (BB) and Press and Blow (PB).
In the Blow and Blow process, both the parison and the final product are created by blowing compressed air or other gases.
In the Press and Blow process, the glass gob is pressed using a physical plunger to form the parison in the blank mold. As in the BB process, the parison is transferred to the finishing mold and blown to achieve the final container shape.
When the glass container is formed, the glass is cooled to a temperature which allows the atoms to move freely while still preserving the glassware’s dimensional characteristics.
We control the annealing process to:
We help you avoid the pitfalls to deliver the quality and value your glass bottle and jar need, on-time and on-budget.Contact Roetell
