1. Adopt advanced energy-saving technology
Save energy, improve melting quality, and extend the service life of the kiln. Another use of energy saving is to increase the amount of cullet. The amount of cullet in foreign countries is 60%-70%. The most ideal is to use 100% cullet to achieve the goal of “ecological” glass production.
2. Lightweight bottles and cans
In developed countries such as Europe, America and Japan, lightweight bottles have become the leading product of glass bottles.
80% of the glass bottles and cans produced by Obeband in Germany are lightweight disposable bottles. Precise control of raw material composition, precise control of the entire melting process, small mouth pressure blowing technology (NNPB), spray cooling of the hot and cold ends of the bottle and can, and advanced technologies such as online inspection are the fundamental guarantee for the realization of the lightweight of the bottle and can.Some countries are developing new surface enhancement technologies for bottles and cans in an attempt to further reduce the weight of bottles and cans. For example, the German Haiye company coated a thin layer of organic resin on the surface of the bottle wall to produce a 1L concentrated juice bottle of only 295 grams, which can prevent the glass bottle from being scratched, thereby increasing the pressure strength of the bottle and can by 20%. The current popular plastic The film sleeve label is also conducive to the lightweight of glass bottles and cans.
3. Improve labor productivity
The key to improving the labor productivity of glass bottle manufacturing is how to increase the molding speed of glass bottles. At present, the commonly adopted method in developed countries is to use multi-group and multi-drop molding machines.
