The Knowledge Of Glass Bottle Production Process

- Feb 05, 2018-

First of all to design and manufacture of molds to determine the glass raw materials to quartz sand as the main raw material, together with other accessories melt under high temperature into the liquid, and then into the mold, cooling, incision, tempering, the formation of glass bottles. Glass bottles are generally rigid signs, signs made from the mold shape. Glass bottle molding in accordance with the production methods can be divided into artificial blowing, mechanical blowing and extrusion molding three. Glass bottles in accordance with the composition can be divided into the following categories: First, soda glass Second, lead glass Third, borosilicate glass

The main raw material of glass bottles is natural ore, quartz, caustic soda, limestone and so on. Glass bottles have a high degree of transparency and corrosion resistance, and contact with most chemicals does not occur when the material properties change. The manufacturing process is simple, free and changeable shape, hardness, heat resistance, clean, easy to clean, and has the characteristics of reusable. Glass bottles as a packaging material is mainly used for food, oil, alcohol, beverages, condiments, cosmetics and liquid chemical products, a wide range of uses. However, glass bottles also have its disadvantages, such as heavy weight, high transportation and storage costs, impatience and impact.
