The main glass bottles raw material is quartz sand, sodium carbonate, calcite,limestone and so on. The glass bottles with a high degree of transparency and corrosion resistance, contact with most chemicals will not occur material properties change. Its manufacturing process is simple, easy to change shape, hardness, heat, clean, easy to clean, and has the characteristics of repeated use.
First of all to design and manufacture mold, glass raw materials to quartz sand as the main raw material, coupled with other materials in the high temperature melting into liquid, and then into the mold oil bottle, cooling, incision, tempering, the formation of glass bottles. The glass bottles are generally rigid and the logo is made of mold shape.
