Several problems that often arise in the
production of glass bottles
1. Deformation of the glass bottle
Since the glass bottles coming in from the
molding die have not yet been shaped in detail, the high temperature at this
moment will often cause the glass jar to collapse and deform, even if the upper
end of the bottle body is too heavy. Inadvertently, if the bottom of the bottle
is not cooled to a certain temperature, it will cause the traces of the
conveyor belt to be printed on the bottle, which will cause the bottom of the
bottle to be too thick.
2. Glass bottle body feed marks
Glass bottle manufacturers recommend
forehearth marks are the most common problem with glass bottles. It can appear
unusually thin, and some can be creative if it works in refracted light. The
most common locations are the corks, short boards and shoulders. Forerunner
marks often appear on the bottle body and the bottom of the bottle, which are
caused by the temperature of the melting furnace.
3.The thickness of the glass bottle is
If the glass bottle manufacturer has an
uneven temperature of the laminated glass gob in the system process of
production and processing, the unit viscosity of the high temperature is small,
and it is blown thin, and the unit friction resistance of the low temperature
is large and thick. In addition, the temperature of the abrasive tool is not
uniform. The high temperature side of the laminated glass is slow to cool, and
it is blown to thin it casually. The low temperature side is blown thick due to
the fast cooling of the laminated glass.
4.The natural environment of glass
The cracks have various designs, some are
wrinkles, and some are thin wrinkles. The key reason is that the gob is too
long due to the low temperature of the gob, and the gob does not fall in the
middle of the initial mold and sticks. caused by the cavity wall.
The bubbles caused by glass bottle
manufacturers in the process of the molding system are often many large bubbles
or how many bubbles are combined together, which is different from the average
spread of the bubbles in the laminated glass itself.
