Glass bottle is a traditional packaging container in our country, and glass is also a kind of packaging material with a long history. With many packaging materials pouring into the market, glass containers still occupy an important position in various packaging, which is inseparable from its packaging characteristics that other packaging materials cannot replace. With the increasing demand for personalized packaging, the development of new abrasive tools to produce different glass bottles has been adopted more and more. So today we will make a brief analysis on the knowledge of glass bottle abrasives.

The mold for glass bottle production is roughly divided into seven parts. The manufacturing cycle of a set of molds takes about 10 to 20 days. The shape and process complexity of the glass bottle determine the length of the mold production cycle.

          The seven parts of the glass bottle mold:

         1.The first is the first model, which, as the name implies, is a mold that preliminarily finalizes the shape of the glass bottle to be produced.

        2.The second is the mold, the main mold, to shape the shape of the glass bottle.

        3.The third is the funnel, which is the process before the glass solution falls from the automatic dispenser into the preliminary mold.

       4.The fourth is the bulkhead. The bulkhead is an accessory that cooperates with the preliminary mold to complete the preliminary processing after the glass solution falls into the preliminary mold.

       5.The fifth is the mouth mold, which is the mold for the bottle mouth and the tool for the glass bottle to move from the initial mold to the finished mold after the initial shaping.

      6.The sixth is the air pump, which is a tool for setting the glass solution under strong pressure through an air compressor after the glass product is initially formed and moved to the mold.

      7.The seventh is the punch and the core. The punch is the mold for the bottle-shaped bottle mouth of the beaker (jar). The size of the punch affects the inner diameter of the bottle mouth. The core is a tool that affects the size of the inner diameter of the small mouth bottle.

The quality of mold directly determines whether high-quality products can be produced. Therefore, in order to develop good mold, generally the following things need to be paid attention to when opening a glass bottle:

1. Environmental conditions. Temperature: The temperature of the same environment must be maintained during the whole process of manufacturing the male mold and the female mold of the glass bottle mold. Humidity: Humidity has a relatively large impact on gel coat and resin curing. The ideal humidity range is generally 40-60. If the relative humidity exceeds 65 when manufacturing glass bottle molds, you need to wait for proper production. Conditions should be carried out before construction, especially in the south or coastal areas, where the humidity is relatively high and requires careful selection.

2. Clean workshop. It is impossible to produce high-quality glass bottle molds in a relatively dirty environment. The position where the male and female molds are manufactured should be highly clean and have a higher maintenance and management standard than the product production position. Therefore, the mold manufacturing At the beginning, the cleaning and dust removal work for mold manufacturing needs to be done well in advance.

3. Clean compressed air. A pure and dry air source is the main factor in the manufacture of glass bottle molds. Adding a small amount of oil or water in the air duct will cause a lot of pitting and pinholes on the surface of the mold gel coat. A lot of labor is needed to repair, so the quality of the mold will be greatly affected.

 4.The choice of raw materials. When selecting raw materials, this is an important condition for making good molds, because the cost of raw materials for making molds only occupies a small percentage of the overall cost, and cannot save the use of product resins or expired raw materials and poor quality. Materials to produce molds.

  5.Have a reasonable molding time. Arranging a more reasonable mold-making schedule is one of the main factors to make a good glass bottle mold. Regardless of whether you use the traditional layup method or choose a new low-shrinkage system, the time required is determined by the chemical characteristics of these raw materials, and a reasonable molding time can ensure that it will not have an adverse effect on the mold.
