What are the forming methods of glass jars?
The forming of each glass jar requires many processes, and the forming method is not single.
Glass jars have also been developed for many years in the glass bottle process. In recent years, they have been formed by manual services. Since then, they have been gradually replaced by automatic assembly lines or automatic technology of mechanical equipment molding. This makes glass glass production and manufacturing sufficiently efficient and efficient. Refined management, but the glass jar technology mostly uses manual service or semi-manual service. Because of the appearance, unit weight and wall thickness of this kind of glass bottle crafts, the composition of laminated glass is different, and the forming method is also different.
From the perspective of the method, it can be divided into the following ones: inhibit forming, blow forming, and draw to form , Float molding, metal wire drawing molding and leakage molding, such as blowing-blowing method and pressure-blowing method for glass bottles, float glass for photovoltaic glass, flat drawing, overflow lead-up, etc., glass test tube using vertical Directly lead upward and horizontal welding heat treatment etc. methods.
Although the forming methods are different, they all use the characteristic that the viscosity of the laminated glass continuously increases as the temperature decreases. As the viscosity changes, the laminated glass has fluidity and gradually hardens into a viscous-extension. In the whole process, it is also harmful to the formation of crystallization characteristics, surface anxiety, thermal conductivity and so on.
