The beauty of machinery - the making of glass bottles
Glass bottles are easy to manufacture, free and versatile in shape, hard, heat resistant, clean, easy to clean, and can be used repeatedly. First of all, we have to design to determine and manufacture the mold, glass bottle raw materials to quartz sand as the main raw material, plus other auxiliary materials dissolved into liquid at high temperature, and then the essential oil bottle into the mold, cooling, notching, tempering, it forms a glass bottle. The glass bottle usually has a rigid logo, and the logo is also made from the shape of the mold. Glass bottle molding according to the production method can be divided into three kinds of manual blowing, mechanical blowing and extrusion molding.
Glass bottle production process mainly includes, raw material pre-processing. Block raw materials (quartz sand, soda ash, limestone, feldspar, etc.) crushed, so that wet raw materials dry, the iron-containing raw materials for iron removal treatment to ensure the quality of glass. With the preparation of materials melting. Glass with materials in the pool kiln or pool furnace for high temperature 1550 ~ 1600 degrees, heating, so that the formation of uniform, bubble-free, and meet the requirements of forming liquid glass molding. The liquid glass into the mold into the required shape of glass products, such as flat panels, a variety of vessels and other heat treatment. Through annealing, quenching and other processes to eliminate or produce stress, phasing or crystallization inside the glass, as well as change the structural state of the glass.
