Things to note when making glass bottle mold

Precautions in the Glass Bottle Mold Making Process

The most critical element in glass bottle production is the glass bottle mold. I believe all glass bottle manufacturers and nearly all sales personnel are familiar with molds, and they all know that molds are made using lathes. However, if you ask about the details of the process, I estimate very few truly understand it. Below are the basic steps involved in making a glass bottle mold, which everyone can refer to.

1. Design Drawing: The sample glass bottle or dimensions are handed over to the designer to create drawings for the entire machine set.
   
2. Pattern Making: Based on the drawings, the blanks for each component are produced.
   
3. Milling with a Milling Machine: The initial mold and blank are milled flat using a milling machine.
   
4. Assembly of All Components: All workshops, all machines, and all lathe operations are activated, with each having its own division of labor. The dry master mold is completed first, followed by the end mold (the bottom of the mold). Once the first part is finished, the second part is completed.
   

At the end of the mold bottle production, there are dry plugs, dry funnels, dry spouts, and dry neck rings. Then, someone dries the core, punch, and cooler.

5. Carving: After the second shaping step is completed, the shaped model or original mold is placed into a carving lathe, where 99% of the work is automatically executed according to the programmed design, saving time and effort while eliminating errors.
   
6. Polishing: The finely carved mold and final mold are polished with fine sandpaper.
   
7. Assembly: The components prepared for each production line are gathered, and the loose parts are combined into finished parts.
   
8. Drilling: All finished parts are drilled or vented according to the drawings.
   

This process ensures precision and efficiency in mold production, which is essential for high-quality glass bottle manufacturing.
