The number on the bottom of the glass bottle is the number of the mold!
In life, we often find that there will be some letters or numbers on the bottom of glass bottles.
After we send samples to customers, customers often ask us what the mold at the bottom of our bottle represents.
In this regard, we give a detailed introduction to the bottom number of the glass bottle mold:
Usually glass bottle production equipment is usually: line machine, manual machine, pouring machine.
The process is that one equipment can combine multiple sets of molds, and the molds are composed of bottle mouth molds, bottle body molds, and bottle bottom molds.
The minimum order quantity for glass bottle production is usually at least tens of thousands. In order to improve the production time, multiple sets of molds can be made.
To produce the same glass bottle, after multiple sets of molds are blown and formed, it needs to be returned to the furnace.
Gradual annealing and cooling are carried out from high temperature to low temperature to increase the stress between glass molecules.
However, the glass bottles produced by multiple sets of molds enter the annealing furnace for mixing, and we cannot distinguish which set of molds are from in terms of shape. The bottom number of the glass bottle mold is usually letters or numbers.
The letter is usually the abbreviation of the manufacturer's company name or the buyer's enterprise abbreviation, and the letter number appears at the same time.
Generally, some numbers will appear, such as: 1, 2, 3, 4, 5, 6... etc. This number plays a very important role in the manufacture of glass bottles.
Therefore, sampling tests are carried out during the packaging process, if quality problems are found.
It is impossible to timely and accurately determine where the quality problem occurs.
Therefore, different numbers are placed on the bottom of the corresponding mold for each group of molds.
When some problems are found, we can more timely and accurately determine the root cause of the problem.
