In December, the manufacturing plant of the Jitong Automotive Parts Industrial Park in Shuangyang District, Changchun City was even busier. A model of the German auto brand that is hot in China is about to usher in new generations, and new chassis parts are being made here.
Changchun, which has a reputation as the “automobile city†in China, is stepping up efforts to build an auto parts industry cluster. At present, many of the world's top luxury car brands have handed over production orders for core components to this Chinese city.
Located in Shuangyang District, this industrial park is part of Jilin Province General Machinery (Group) Co., Ltd., which has achieved a sales revenue of RMB 12 billion. Parts produced using aluminum casting and forging technology are mainly supplied to Volkswagen, Audi, and Porsche. , Mercedes-Benz, BMW and other auto brand OEMs.
Li Xiaoxuan, executive deputy general manager of the company, pointed to the wheel bracket of an Audi model exhibited on the workshop, saying that this is a new generation of components that will be available in the first half of next year. “Customers and us have prepared for this for two to three years. ".
At the end of the main road of the industrial park, a large slogan board is extremely eye-catching: it is committed to building the world’s largest R&D and production base for auto parts.
Li Xiaoxuan said that they plan to achieve this goal by 2026. At present, the company has established two joint ventures in China with two companies in Europe, and has introduced advanced aluminum forging and processing technologies for auto parts to China.
“Lightweighting is an important means of energy saving and emission reduction for automobiles. We use aluminum materials instead of steel for R&D and manufacturing and are at the forefront of the nation,†said Li Xiaoxuan.
At present, the global automotive industry is in a period of great changes in various technologies and innovative applications. Changchun, China's automobile industry, is also closely following the trend of the future and seeks to develop the industry to high-end.
In the Changchun Automobile Economic and Technological Development Zone, an international cooperation zone for parts and components is being built on the basis of the existing six industrial parks such as powertrains, shaft gears, molds, private economy, industrial incubation, and Fuao. The goal is to At the end of the 3rd Five-Year Plan period, the total number of parts and components companies exceeded 500, forming a complete chain supporting system for auto parts.
Qu Xingtao, deputy director of the Changchun City Bureau of Industry and Information Technology, told reporters that the local company is leading a large number of projects such as the FAW EA211 engine and millions of engines and the Audi Q factory to lead the transformation and upgrading of the automobile and parts manufacturing industry.
The opening of the local international freight trains to Europe has facilitated the development of European auto parts for auto parts produced in Changchun.
"Swedish and German customers urgently needed a batch of parts. If the cost of air transportation is too high, and there is an international freight train, the speed is fast and the price is reasonable. This business has become a success." Li Xiaoxuan cited an example to rely on leading to Europe. The railway artery of major automobile production bases, where auto parts products have become very competitive.
Tinplate (SPTE, tin-coated iron) is the common name of cold-rolled electroplated tin sheet, which refers to the cold-rolled low-carbon sheet steel or steel strip coated with commercial pure tin on both sides.
Characteristic advantage
1.Light permeability
In addition to triggering deterioration reactions in foods, light also causes changes in proteins and amino acids. The exposure of vitamin C to light makes it easier to interact with other food ingredients, resulting in a large loss. According to research and analysis, the loss of vitamin C in transparent glass bottles of milk is 14 times higher than that in dark bottles of milk, light will also cause milk to produce oxidative smell, as well as nuclide, methionine and other cracking and loss of nutritional value, tinplate can opaque light makes the highest preservation rate of vitamin C.
2.Good sealing
The barrier of packaging containers to air and other volatile gases is very important for the preservation of nutrients and sensory quality. The comparison of various juice packaging containers showed that the oxygen permeability of the container directly affected the Browning and vitamin C preservation of the juice. The preservation of vitamin C is better in metal cans, glass bottles, aluminum foil glue layers and cartons with low oxygen transmission rate, of which iron cans are the best.
3.Reduction of tin
The tin in the inner wall of the tin plate will interact with the oxygen remaining in the container during filling, reducing the chance of the food ingredients being oxidized. The reducing effect of tin has a good preservation effect on the flavor and color of light colored fruits and juices, so the juice cans filled with unpainted iron cans have better nutritional preservation than those filled with other packaging materials, and the Browning change is slight, the acceptance of flavor quality is better, and the storage period is extended.
Use
The application of tinplate is very wide, from as food and beverage packaging materials to grease cans, chemical cans and other miscellaneous cans, the advantages and characteristics of tinplate provide content in the physical and chemical properties of good protection.
