First, the surface quality of glass bottles: downward divided into material color, smoothness, transparency, etc; The top element is the glass bottle material color, which can be divided into three levels according to regional norms: pure white material, high white material and ordinary white material;; The same material color is the smoothness and transparency of the glass bottle. The appearance of a good bottle should be free of impurities, bubbles, cold spots, sticking, wrinkle, putty, etc.

Another thing to note is that the bottle body is "double stitched". There is a single glass bottle manufacturer with lax quality requirements, which often presents the phenomenon of large stitches and double stitches; Finally, when looking at the bottle directly, the clarity and permeability of the large mouth glass bottle are better, and the small mouth glass bottle cannot have particularly significant dizzy waves.

Secondly, the connotation quality of the glass bottle: there are many subdivisions in this way, such as the strength of the glass bottle, the temperature difference between rapid cooling and rapid heating, the straightness of the bottle body, the thickness of the bottle body, the no deformation of the bottle body, the crooked neck, the flatness and roundness of the bottle mouth, the no cold lines, the full silk lines, the no pimples, drum and broken wires, and the no diameter tumors in the bottle mouth. The most common shortcomings of Xuzhou glass bottle manufacturers are the following --- small mouth bottle crooked neck, small mouth flat bottle shaking, large mouth bottle drum wire and other phenomena.

The crooked neck of the small mouth bottle will affect the appearance, so it cannot be filled or sealed by the machine; The reason is that the mold elements, the production machine speed is fast, and the bottle clamp is not matched; The shaking of the small mouth flat bottle is mostly caused by the failure to deal with the anti-skid line at the bottom of the mold, the deviation of the bulkhead mark, and the fast machine speed and poor shaping; As a result of the bulging of the large mouth bottle, the silk pattern becomes thicker and cannot be sealed. The reason is that the die is large, the heat dissipation is not good, or the air pump head is shallow.
