Stolle's Shanghai Technology Workshop Summary

Stall Stolle of the United States is the leading global manufacturer of stamping two-piece cans and easy-open covers. Over half a century after the war, its equipment and technology have spread throughout Europe, the United States, Japan, and developing countries.
In late September this year, the company held the 2005 China Can-making and Covering Technology Seminar in Shanghai. A total of 242 delegates from the relevant factories nationwide attended the lectures and seminars. The workshop was organized by the company's general agent "Guangzhou Deno company." The technical translation of the lecture was conducted by two women, including Deno's Liu Qiong, and the translation was accurate and smooth.
Professor Zhang Wencan, deputy secretary-general of the China Baoxie Metal Containers Committee, pointed out in a brief speech: China's canned exports continue to grow this year and may reach 2 million tons. In addition, please also pay attention to the can makers, lid makers, and canneries:
1. In developed countries, in recent years, a large number of two-shallow tanks have been used, with capacities ranging from 70 to 350 milliliters, and sheet thicknesses ranging from 0.12 to 0.16 millimeters, that is, DR secondary cold-rolled tinplates or composite aluminum alloy sheets.
2. For cans less than one kilogram of export, easy-open covers should generally be used.
3. When importing stamping cans and capping equipment, attention should be paid to the technical strength and integrity records of relevant manufacturers.

In recent years, a German company has exported large quantities of equipment and equipment to Huangyan and other factories.
The meeting officially began. The Chief Executive Officer, David Groetsch, first introduced the company's Canning and Capping Department profiles. Then, four people, including G. Butcher and Bob Gary, who are presidents of the manufacturing department, gave five hours of technical lectures on three aspects: capping, can making, and tinplate printing. They produced a total of more than 130 technical pictures and diagrams, of which 54 were technical information on tin cans for easy opening of food cans. The content was that the company used ordinary tin and secondary cold rolled tinplate to make improved (CM type) easy to open. Gaila ring and nicks and other related technical data.

Standard easy open cover ring

CM easy open cover ring

The advantages of CM easy open cover ring:
1 ring hole increase 30%
2 Eliminates cracking of the base of the tongue 3 20% longer starting line
4 Reduced pull off

The following three graphs are actual measured curves of various open-end breaking forces and full opening forces.
It can be seen from these curves that the breakaway force and full opening force of the improved easy-open lid are smaller than those of the standard easy-open lid. In addition, the opening force and full opening force of the easy-open lid of the secondary cold rolled tinplate (DR iron) are always smaller than the easy opening of the once cold rolled tinplate (SR iron).

In addition, the company also made detailed predictions on the future growth of aluminum two-piece cans (for carbonated beverages and beer) in Asia and China globally. The relevant charts are as follows:

Distribution of empty cans in major states of the world: (1bn = 1,000,000,000 = one billion)

China's various beverages 1988-2004 growth figure unit: 1 billion liters

Beer Beer Other Non Carbs Beverages

CSD carbonated (inflatable) beverage

In short, this workshop was very successful and everyone listened very carefully. If domestic related companies need to further study the technical materials and diagrams involved in the lectures, please contact Dean Liu Qiong.
