It is a woman's nature to love beauty. I believe that nail polish and perfume are familiar to everyone. Different glass bottles will have different marks. If you want to have different effects, it is necessary to spray perfume bottles. But many people just find that bubbles and scratches will appear on the glass bottles during the process. What is the reason?
When the glass preform falls into the initial mold, it cannot accurately enter the initial mold, and there is excessive friction with the mold wall, forming wrinkles. After blowing air, the wrinkles diffuse and enlarge, forming wrinkles on the body of cosmetic glass bottles.
2. The scissor marks on the upper feeding machine are too large, and some bottles have scissor marks on the bottle body after forming.
3. The initial and molding materials of the glass bottle are poor, with insufficient density. After high temperature, it oxidizes too quickly, forming small pits on the surface of the mold, resulting in an uneven surface of the formed glass bottle.
4. Poor quality of cosmetic glass bottle mold oil can lead to insufficient lubrication of the mold, reduced dripping speed, and rapid change of material type.
5. The initial mold design is unreasonable, with large or small mold cavities. After the material drips into the forming mold, it spreads unevenly during blowing, which can cause spots on the glass bottle body.
6. Uneven material dripping speed of the machine and improper adjustment of the air nozzle can cause the initial and molding temperatures of the glass bottle to be uncoordinated, which can easily create cold spots on the glass bottle body and directly affect the smoothness.
7. Unclean glass liquid or uneven material temperature inside the kiln can also cause bubbles, small particles, and small hemp billets to appear in cosmetic glass bottles.
8. If the speed of the row and column machine is too fast or too slow, uneven cosmetic glass bottle body, uneven bottle wall thickness, and flower spots will occur.
