Appearance defects are mainly inspected everywhere in the appearance design (bottle stopper, short plate, bottle body, bottle bottom), and remove the goods with obvious defects. Exterior defects include bubbles, urinary stones, nodules, cracks, uneven glass wall thickness, product deformation, parting surface stitching lines, mesh structure cracks, excessive restriction or design skew, foreigner residues, bottle stoppers Roughness, unevenness, deformation of the bottle stopper, not only the surface of the product, but also the distortion of the bottom of the bottle.

After checking the specifications and model limits, it is clear whether the product is within the scope of standard public service. The specification and model limit inspection mainly includes production capacity, practical activity capacity, bottle diameter, the limit of a part of the bottle stopper and other non-limits.
