Appearance quality: It is divided into material color, finish, transparency, etc.; the first element is the material color of glass bottle, which is divided into three grades according to regional standards: fine white material, high white material, and ordinary white material; Look at the finish and transparency of the glass bottle. The appearance of a good bottle should be free of impurities, bubbles, cold spots, sticky bottles, wrinkled skin, no putty, etc. Another point to pay attention to is the "double suture" of the bottle body, and there are individual glass The quality requirements of bottle manufacturers are not strict, and the phenomenon of large stitching and double stitching often occurs; finally, when looking at the bottle body directly, the clarity and permeability of the large-mouth glass bottle are better, and the small-mouth glass bottle cannot have particularly obvious dizzy wave patterns. .
Intrinsic quality: There are more subdivisions in this way, glass bottle strength, rapid cooling and rapid heating temperature difference, bottle verticality, bottle body thickness, bottle body no deformation, crooked neck, bottle mouth flatness and roundness, no cold streak frying mouth, silk The pattern is plump, there is no pyridine wire, the drum wire is broken, and there is no diameter tumor in the bottle mouth. The most common faults of Xuzhou glass bottle manufacturers are the following: small-mouth bottle crooked neck, small-mouth flat bottle shaking, large-mouth bottle drum wire, etc.; small-mouth bottle crooked neck will affect the appearance and cannot be filled by machine Sealing; the reason is the mold factor, the fast production machine, the bottle clamps are not matched, etc.; the small-mouth flat bottle shakes mostly because the mold bottom anti-skid line is not handled properly, and there are some reasons such as bulky head printing, and the machine speed is fast and the shape is not good. Caused; the result of the large mouth bottle drum wire is that the wire pattern becomes thick and cannot be sealed, because the large die is not good for heat dissipation or the pumping head is shallow.
