Measuring defects


( 1) The bottle is too large, the bottle diameter than the upper limit standard. When the bottle sag is also likely to lead to larger diameter of some point.

( 2) The bottleneck blocking ( Narrow neck) The requirements of the bottleneck: inside diameter is less than. Some products according to the requirements of the customers filling pipe, in the design shown on the drawings within the effective length, such as a narrow neck, is not acceptable. The special requirements of products to visual. The inner ring:

bottlenecks bottlenecks or upper part of the bottle glass concentric rings.

( 3) Bottle diameter is too small: bottle diameter less than the specified requirements. With plug gauge or a vernier caliper can be measured. The double mouth could lead to a smaller diameter.

( 4) High: high bottle more than the upper limit standard, bottleneck could lead to a long bottle high levels.

short: bottle bottle height can not meet the standard lower limit value, the shrinkage is too big or seat can produce bottle short.

( 5) The bottle out of round: ovality is from circle to ellipse bottle section of a deformation, usually with the length of the elliptic represented the difference between the shaft. Namely: at the beginning of the same measuring surface rotates the difference between the maximum and minimum values beyond the bottle out of roundness standard range.

the bottle bulge: the bottle deformation, bulge outward in excess of the prescribed requirements.
