Red wine bottle production process

Red wine bottle production process is composed of a number of links, the following to a typical case to introduce in detail.
1. Raw material procurement
The main raw material of the wine bottle is lead-free glass, so the purity and quality of the raw material should be ensured. In this case, the raw material procurement company is one of the largest glass products companies in the world, and they purchase glass raw materials from all over the world to ensure the quality of raw materials.
2: Ingredients
The raw materials are prepared into the required formula of glass products in a certain proportion, and the formula of the wine bottle in this case is: 70% lead-free glass, 20% feldspar, 5% silica sand and 5% grass and wood ash.
Step 3 Melt
After the ingredients are put into a furnace for high temperature melting, so that it becomes a plastic state. In this case, the furnace temperature was 1500 ° C and the duration was 10 hours.
4. Make bottles
After melting, the molten liquid is poured into a glass molding machine, which is molded into the shape of a wine bottle through the double action of high temperature and pressure, in this case at a speed of 400 bottles per second.
5. Roasting and cooling
After the bottle is made, it is put into a roaster for the first processing, so that the glass bottle reaches the strength standard, in this case the roasting temperature is 580 ° C and the duration is 2 hours. The bottle is then placed in a cooling furnace to cool it slowly to prevent the glass from cracking due to rapid cooling. In this case, the cooling time was 8 hours.
Step 6 Trim
After cooling the bottle for a second processing, this link is also called “trimming”, mainly to remove the burrs and bumpy parts on the bottle, so that the appearance of the bottle to achieve the ultimate smoothness
