In the past two years, with the increasing proportion of glass bottles in the market, more and more people will choose glass bottles when choosing packaging materials. When people choose glass bottles, they also have more and more quality requirements. higher. Sometimes we will find that the glass bottles produced will have some failures after forming. What is the reason for this? The reasons for the failure of glass bottles after molding.
The material of the mold is poor. Sometimes when producing glass bottles, in order to reduce costs, some manufacturers will choose molds with poor material for production, so it is easy to cause insufficient density due to the material of the wine bottle mold, and the oxidation is too fast after high temperature, so it is very easy. This leads to the formation of small pits on the surface of the mold, resulting in an unsmooth surface of the glass bottle after molding. Therefore, we should pay attention to selecting molds with better materials during production, so that the produced glass bottles will not have surface failures. The initial mold design is unreasonable. In the production of glass bottles, sometimes due to the unreasonable design of the initial mold, the mold cavity is too large or too small. During production, after the gob enters the forming mold, it is blown and spreads unevenly, so that when using It will cause spots on the bottle body of the glass bottle, which will seriously affect the quality of the glass bottle.
