What's the secret to the numbers at the bottom of the glass bottle


    The bottom number of the bottle is the number of the mold!In daily life, it is often found that there are some letters or numbers at the bottom of the glass bottle. For this, we will introduce the number at the bottom of the glass bottle mold in detail:

    Usually glass bottle production equipment is usually: line machine, manual machine, inverted machine, the process is one equipment can combine multiple sets of molds, and the mold has bottle mouth mold, bottle body mold, bottle bottom mold supporting composition.


    Glass bottle production minimum quantity usually less * * in the tens of thousands of, in order to improve the production time, can make multiple sets of mould, to produce the same kind of glass bottle, bottle blowing in multiple sets of dies, the need to return into such as furnace, by high temperature and low temperature annealing cooling, step by step to improve stress between molecules, but multiple sets of mold production of glass bottles into the hybrid annealing furnace, we cannot distinguish from the aspects of shape of which set of mold.The number at the bottom of the glass bottle mold is usually letters or numbers. The letters are usually the abbreviation of the manufacturer's company name or the purchaser's enterprise name. When the letter number appears, there are usually some numbers, such as: 1, 2, 3, 4, 5, 6......And so on, this number has a very important role for glass bottle manufacturing.Therefore, in the process of sampling inspection, if quality problems are found, it is impossible to determine the origin of quality problems timely and accurately. Therefore, different numbers are made at the bottom of the corresponding mold of each group of molds. When some problems are found, we can determine the root cause of problems more timely and accurately.
