We summarize the glass joint line highlight or protrude mouth edge defects.
This is because the model is insufficient right or install components manufacturing anastomosis.
Model damage, joint surface dirt, top core filed late before enter the location of eco-friendly tube material has fell into the initial shape, can make the part of the glass out of the gap medium voltage or blown out.
1） Crack crack is the most common glass bottles of faults. It can be very thin, and some can only be found in the reflected light. Often, the part of the produce is the bottle mouth, bottlenecks and shoulder also often crack at the bottom of the bottle and bottle.
（ 2) Uneven thickness of this refers to the uneven distribution of the glass on the bottle. Mainly glass material drops of non-uniform temperature, high temperature part of viscosity is small, easy to blow thin; A part of low temperature resistance, thicker. Model non-uniform temperature, high temperature cooling slowly, one side of the glass easily blown thin, low temperature side, because of the thick glass blowing and rapid cooling.
（ 3) Deformation is expected to drop temperature and the temperature is too high, the forming die out of the bottle is not fully shaped, tend to collapse deformation. Sometimes printed on the bottom of the bottle is soft belt of grain and make the bottom of the bottle.
（ 4) Not full the gob temperature too low or too cold model can make the place such as the mouth, the shoulder is not full, generation gap, flat shoulder and defects such as decorative pattern is not clear.
（ 5) Cold spots on the glass surface is not smooth patches called cold spots. This kind of defect causes mainly model supercooling temperature, occurs at the beginning of the production or downtime reproduction.
（ 6) Protrusions glass joint line highlight or protrude mouth edge defects. This is because the model is insufficient right or install components manufacturing anastomosis. Model damage, joint surface dirt, top core filed late before enter the location of glass material has fell into the initial shape, can make the part of the glass out of the gap medium voltage or blown out.
（ 7) Furrow wrinkles have various shapes, some crease and some piece of very fine wrinkles. Cause of wrinkles is mainly due to the material drop too cold, gob is too long, is expected to drop not to fall in the middle of the initial shape and adhesion in the cavity wall.
（ 8) Surface defect glass bottles of hair, uneven surface, mainly due to cavity table is not smooth. Model of the lubricating oil is not clean or dirty oil brush, also can make the decrease of the quality of the glass surface.
（ 9) Bubbles to form in the forming process is often a few large bubbles or together a number of small bubbles, the glass itself and there is a difference between the uniform distribution of small bubbles.
（ 10) Scissors to print due to shear adverse residual obvious traces on the bottles. A gob often have two scissors, scissors printing at the bottom of the above, affect the appearance. The scissors in bottle, below is often cracks originated.
