In developed countries such as Europe, the United States and Japan, lightweight bottles have become the leading products of cosmetic glass bottle manufacturers. 80% are lightweight disposable bottles. Accurate control of raw material composition, precise control of the whole melting process, small mouth pressure blowing technology (nnpb), cold and hot end spraying of bottles and cans, on-line detection and other advanced technologies are the fundamental guarantee to realize the lightweight of bottles and cans.
Adopt advanced energy saving technology
Another way to save energy, improve the melting quality and prolong the kiln is to increase the amount of broken glass. The amount of broken glass in foreign countries can reach 60% - 70%. The ideal is to use 100% broken glass to achieve the goal of "ecological" glass production.
Improve production concentration
In order to adapt to the severe competition situation caused by the challenge of other new packaging products in cosmetic glass packaging industry, a large number of cosmetic glass packaging enterprises began to merge and reorganize to improve the concentration of glass container industry, so as to optimize the allocation of resources, improve the scale efficiency, reduce disordered competition and enhance the development ability. This has become the current world glass bottle packaging industry The trend. At present, the domestic cosmetic glass bottle industry is facing a variety of tests. It is hoped that large domestic enterprises can learn from foreign management methods and technologies, so that China's cosmetic glass bottles will be forever green and full of vitality in foreign countries.
Improve labor productivity
The key to improve the labor productivity of cosmetic glass bottle manufacturing is how to improve the molding speed of cosmetic glass bottle. At present, the commonly adopted method in developed countries is to select multi group and multi drop molding machine. The large kiln matched with the high-speed molding machine must be able to supply a large quantity of high-quality glass liquid stably, and the temperature and viscosity of the droplet should meet the requirements of the best molding conditions. Therefore, the composition of raw materials must be very stable. Most of the refined standardized raw materials used by glass bottle manufacturers in developed countries are provided by specialized raw material manufacturers. The digital control system should be used to ensure the furnace thermal parameters of melting quality to realize the optimal control of the whole process.
