In developed countries such as Europe, America and Japan, lightweight bottles are the leading products for glass bottles and cans. Save energy, improve melting quality, and extend the life of the furnace. One way to save energy is to increase the amount of broken glass, and the amount of broken glass imported abroad reaches 60%-70%. The ideal is to use 100% broken glass to achieve the goal of "ecological" glass production.
1. Use advanced energy-saving technologies to save energy, improve melting quality, and extend the service life of kilns. One way to save energy is to increase the amount of broken glass, and the amount of broken glass imported abroad reaches 60%-70%. The ideal is to use 100% broken glass to achieve the goal of "ecological" glass production.
2. Lightweight bottles are developed in Europe, America and Japan. Lightweight bottles are the leading products for glass bottles and cans. 80% of the glass bottles produced by Obedand in Germany are lightweight one-time bottles. Precise control of raw material composition, precise control of the entire process of melting, NNPB, hot and cold-side spraying of bottles and cans, on-line inspection and other advanced technologies are the fundamental guarantees for achieving lightweighting of bottles and cans. Some countries are developing new surface enhancement technology for bottle cans in an attempt to further reduce bottle weight.
For example, the German company Haiye Co., Ltd. applied a thin layer of organic resin to the surface of the bottle wall to produce a one-liter concentrated juice bottle of only 295 grams, which can prevent the glass bottle from being scratched, thereby increasing the pressure strength of the bottle by 20%. The popular plastic film sleeve labels are also beneficial to the lightweight of glass bottles and cans.
3. The key to improving labor productivity and improving the productivity of glass bottles manufacturing is how to increase the molding speed of glass bottles. At present, the commonly adopted method in developed countries is the use of multi-group, multi-drop molding machines. For example, the speed of 12 sets of double-dripping serial bottle-making machines produced abroad can exceed 240/min, which is more than 4 times higher than the 6 sets of single-droplet forming machines commonly used in the country.
In order to ensure high-speed quality and high molding pass rate, electronic timers are used instead of traditional cam drums. The main actions are all using forming parameters. The servo drive can be optimized to replace the mechanical transmission that cannot be arbitrarily adjusted. : China Wine News, China Wine News Network), and a cold-end online inspection system automatically rejects waste.
The entire production process is controlled by the computer in a timely manner, which can ensure the best molding conditions, ensure high-quality products, run more stable and reliable, and the reject rate is extremely low. Large-scale kilns that match high-speed molding machines must have a large capacity to stably supply high-quality glass liquids. The temperature and viscosity of the gobs must meet the requirements of the best molding conditions. For this reason, the raw material composition must be very stable, and the refined standard raw materials used by glass bottle manufacturing enterprises in developed countries are mostly provided by specialized raw material production enterprises. To ensure the melting quality of the furnace thermal parameters to use digital control systems to achieve the best control of the entire process.
4. Increase production concentration In order to adapt to the severe competition situation caused by the challenge of other new packaging products in the glass packaging industry, a large number of glass packaging manufacturers started mergers and reorganizations to increase the concentration of the glass container industry in order to optimize resource allocation, increase economies of scale, and reduce Disorderly competition and enhanced development capabilities have become the current trend of the world glass packaging industry. The production of glass containers in France is entirely controlled by the Saint Gobain Group and the BSN Group. The Saint-Gobain Group covers building materials, ceramics, plastics, abrasives, glass, insulation and reinforcement materials, and high-tech materials, among which glass containers account for 13% of total sales, which is approximately 4 billion Euros; Outside the production base, it also has production bases in Germany and the United States. In the early 1990s, the United States had 32 glass bottle manufacturers and 118 factories. In February 1997, four companies such as OI, BALL, and FOSTER controlled the 92% share of the glass bottle market in the United States through mergers, acquisitions, purchases, and other means.
OI also acquired many glass factories in 38 other countries around the world, becoming the world’s largest producer of super-sized glass jars, trying to dominate the global market for glass bottles and cans. At the same time, major international companies such as American OI, Australian ACI, Hong Kong New World Group, and French Saint-Gobain Group have also poured into China and established many joint ventures or wholly-owned glass bottle manufacturers.
