Glass wine bottles are made of ordinary silicate materials and various auxiliary raw materials, after high temperature melting, molding, annealing, surface treatment and inspection. However, glass wine bottles will inevitably have cracks in the production process, and the reasons for this are diverse, so how to solve it? Let's take you to understand.
Generally speaking, if there is a crack in the bottle mouth part, it is necessary to eliminate the cut print as much as possible, reasonably adjust the drip temperature and material shape, the drop head should be smooth, adjust to the cooling air, keep the temperature of the core and the mold suitable, and appropriately adjust the time and pressure of blowing, but do not blow on the bottle mouth.
If there is a problem with the mold of the glass bottle, it will also lead to cracks, such as the joint surface of the mold is worn, it will be blown outside the bottle mouth when blowing, the size of the mouth mold is not too large, and the blowing head is too deep or too shallow will have problems. The design of the glass bottle mold can be modified to make it easy to stamp, and the size of the stamping port can be appropriately increased to reduce the phenomenon of cracks.
