Glass bottle such as 500ml Dark Green Cooking Oil Glass Bottle generally has a rigid mark, the sign is also made of mold shape. Glass bottle molding can be divided into manual blowing, mechanical blowing and extrusion molding.
1. Raw material preprocessing. The massive raw materials (quartz sand, soda, limestone, feldspar, etc.) are crushed to dry the wet raw materials. Iron containing raw materials are treated to ensure the quality of glass.
2. The melting system. The glass compound material is heated at high temperature (1550~1600 degree) in the tank kiln or furnace to form uniform, non-bubbling liquid glass that meets the molding requirements.
3. To shape. Put liquid glass into the mold to make the desired shape of glass products, such as plate, various utensils.
4. Processing. Through annealing, quenching and other processes, the stress, phase separation or crystallization inside the glass is eliminated or produced, and the structural state of the glass is changed.Finally, glass bottle such as 30ml Mini Honey Jar is completed.
