The packaging of wine bottles on the market is becoming more and more exquisite and different, and improving the quality of mini glass bottles has become a difficulty for many glass bottle manufacturers to overcome.
After research by VIT, the following results have been sorted out, taking mini vodka bottles bulk as an example: the first mold is a preliminary mold, the main purpose is to fix the degree of glass frit forming the bottle mouth and to cool it to a certain extent. The second mold is the forming mold to shape the glass bottle, and there is an unsolvable problem in direct molding with a mold. If the material temperature is relatively high, the air temperature inside the bottle is much higher than that outside the bottle [about 900-1000 degrees in the bottle] during the cooling process of the bottle after molding, resulting in a very low air pressure in the bottle, which will cause the bottle body to shrink inward, causing the bottle body to shrink inward. Deformation of the bottle body If the material temperature is relatively low, the bottle bottom will be thinner than the pressure that the bottle can withstand due to the poor fluidity of the glass frit during the blowing process.
After testing and paying attention to the above details, the production quality of mini vodka bottles bulk can be improved by 30%.
