Notes for the process of printing glass bottles

Although the glass color glaze used in the pattern of printed glass bottles has been integrated with the glass, but its inherent glass characteristics also determine that the number of times it is used is limited to seven, too much reuse will bring adverse consequences.Decals, on the other hand, can only be used once, and the pattern is not complete, because of the inherent acid and alkali resistance and erosion resistance of the decals after curing at high temperature.Appearance quality: to material color, finish, transparency, etc.Elements are glass bottle material color, according to the regional standards are divided into: white white material, high white material, white material three grades.

The same material color is the glass bottle finish, transparency, the appearance of a good bottle should be free of impurities, bubbles, no cold spots, sticky bottle, no wrinkles, no putty, and so on, there is a point to pay attention to the bottle body "double seamline", there are a few glass bottle manufacturers lax quality requirements, often appear large and double seamline phenomenon;Finally, the clarity and permeability of the glass bottle with a big mouth is good, and the glass bottle with a small mouth should not have particularly obvious wavy lines.Internal quality: there are many subdivisions, such as glass bottle strength, temperature difference between quench and quench, perpendicularity, thickness of the bottle body, no deformation of the bottle body, neck distortion, roundness of the bottle mouth, no cold wrinkles, full silk thread, no broken filament of the bottle mouth, and no diameter tumor in the bottle mouth.

The most common problems with glass bottle manufacturers are the following: bottle neck slouching, bottle body shaking and large bottle drum.Small mouth bottle neck slanting effect is to affect the appearance, can not machine filling can not machine sealing;The reason is due to the mould factor, the fast production machine and the incomplete bottle tongs.The shaking of the flat bottle with small mouth is mostly caused by the non-slip line of the die bottom not being handled well, the deviation of the head printing and the lack of good organic speed.The consequence is that the filaments become thicker and cannot be capped. The reason is that the large heat dissipation of the mouth mold is not good or the air pump head is shallow.
