Beer bottle production process

Beer bottles are primarily made from quartz sand, using a precise and methodical production process. The steps involved are as follows:

1. Mold Design and Manufacturing:
   • The first step is to design, determine, and manufacture the mold and other necessary accessories. The raw materials are melted into liquid at high temperatures, often using liquefied petroleum gas for the melting process. The molten glass is then blown into various shapes using air pressure before being injected into the mold. Following this, the glass is tempered, cooled, and cut to form the final bottle shape. The rigid marks on the glass bottles are a result of the mold design. This stage requires skilled technical personnel, as any mistake can damage the materials and lead to significant waste.

1. Pre-treatment Section:
   • In the pre-treatment section, the glass bottles undergo several processes, including pre-release, main release, and table adjustment. For production facilities in colder climates, it is important to maintain an adequate temperature in the main release area to ensure proper insulation. Without proper temperature control, the pre-treatment effect may be compromised.
2. Preheat Section:
   • After pre-treatment, the bottles enter the preheat section, which typically lasts for 8-10 minutes. It is recommended that the workpieces retain some residual heat when they reach the powder chamber to enhance the adhesion of the powder coating.
3. Purification Section (Soot Blowing):
   • If the production process demands high-quality finishing, the purification section is crucial. This step removes dust from the workpiece surface. If dust is not adequately removed, particles will remain on the surface after processing, which can significantly reduce the quality of the finished product.
4. Powder Spraying Section:
   • During the powder spraying stage, the bottles are coated with powder and then baked. Attention must be paid to the temperature and baking time, which generally ranges between 180-200 degrees Celsius, depending on the material of the workpiece. The drying furnace should be positioned close to the dusting chamber, ideally within 6 meters, to ensure optimal results.
