Yuefeng Aluminum not only provides financial support for the group, but also provides a full range of marketing support for the company, the development and establishment of marketing networks, "there are industry fairs, we are focused on promoting."
Deep cooperation between upstream and downstream enterprises
In Longkou Bright Metal Container Co., LTD., the machine rumbles in the production workshop, the basic cover punching machine, rotary table, automatic cover balancing system and basic cover coating visual inspection, light inspection machine and other production equipment, fast and orderly operation. A board of finished products are placed neatly, quality control personnel are strictly sampling the finished products... Song Shizhan, general manager of the company, is discussing the problem of lightweight metal packaging with technical personnel.
Brit is a gazelle enterprise in Shandong Province and a national high-tech enterprise. It provides easy-to-pull cover and bottom cover for many well-known beverage brands such as Red Bull, Want Want, Yang Yuan, etc. The annual output value of the enterprise is more than 600 million yuan. "Brit settled in Longkou, looking at the industrial base of the aluminum industry here." Song Shizhan said.
Nanshan Aluminum's continuous breakthroughs in aviation aluminum, rail transit aluminum, ultra-thin aluminum and other fields have attracted many related enterprises to settle down. Bo Ret, terene aluminum, Ao Ruijin and so on are the downstream customers of Nanshan Aluminum industry, and now they have made a world in the packaging aluminum industry.
"The entire industrial chain benefits from Nanshan Aluminum's research and development capabilities. Take a small can pull ring as an example, Nanshan Aluminum industry produces aluminum strip, the downstream Sanyuan Aluminum industry will process the aluminum strip into the pull ring, we will process the pull ring material into the pull ring." Song Shizhan said that if the customer put forward the demand to reduce the pull ring, they will feedback the demand to ternary aluminum, ternary aluminum to Nanshan aluminum to reduce the demand for aluminum, Nanshan aluminum will update the production process in time to produce thinner aluminum strip.
Song Shizhan introduced that the research and development process requires repeated communication between professional and technical personnel of Nanshan, Sanyuan and Beaut. "Because of the advantages of the regional cluster, the three companies can quickly and effectively communicate with each other about the problems arising in research and development, and can also conduct field research at each production link at any time to improve the efficiency of research and development."
This year, the company invested 3 million yuan in a new set of easy cover mold equipment, the use of international high-end new technology, the application of new materials, the soda cap was introduced to the Longkou factory, the production of easy cover for beer, the cover thickness of 0.22 mm. After 2024, the annual output value of the enterprise can reach 760 million yuan.
Add "Pearl in the crown of industry"
In the Nanshan aluminum production workshop, a square of aluminum ingots after hot rolling into a piece of about 28 meters long, weighing about 7 tons, the thickness of 60 millimeters of aviation sheet. This is a process similar to "rolling pastry" in life, the difference is that the aviation plate for "rolling" requirements are strict, must be zero error.
"We have been involved in the research and development of the domestic large aircraft C919 since 2017." Lu Zhengfeng, chairman of Shandong Nanshan Aluminum Co., LTD., said that in the process of overcoming difficulties, the company successfully broke through the key core technology of aluminum profiles used in domestic aviation wings and overcome a number of technical problems in the industry.
The manufacturing of large passenger aircraft is known as the "pearl in the industrial crown" because of its complex and cutting-edge technology, and it is a complex system engineering across disciplines, industries and regions. Since March 2017, Nanshan Aluminum began to participate in the research and development of C919, has passed the certification of 2 series and 7 series of alloy models of thick plate and sheet products, and has begun to batch supply, products are mainly used in fuselage frame, partition, wing panel, wing SPAR and wing rib and other parts. Among them, 7 series aluminum alloy thick plates have been applied to the production of C919, ARJ21 and other models.
