China Drying News reported on January 16th from the Ministry of Industry and Information Technology that the Ministry of Industry, the National Development and Reform Commission, the Ministry of Science and Technology, and the Ministry of Finance jointly issued the "Action Plan for Addressing Climate Change in the Industrial Sector (2012-2020)" requirement. By 2015, petrochemical and chemical industry The industrial added value carbon dioxide emissions of industrial units decreased by 18% and 17% respectively compared with 2010. This is more than 2% higher than the previous target of carbon emission reduction in the industry. The relevant experts said in an interview with reporters that by strengthening energy conservation efforts and increasing the capacity of the festival, they can meet the national requirements for carbon reduction. According to the reporter's understanding, the target of carbon emission reduction for the “Twelfth Five-Year Plan†determined by the petroleum and chemical industry was 15%, and the target required by the country has increased by more than 2%. In this regard, Wang Wentang, deputy director of the National Chemical Energy Conservation (Emission Reduction) Center Expert Committee, said that carbon emission reduction and energy conservation are inextricably linked and there is a natural link between the two. 70% of the greenhouse gas effect is caused by carbon dioxide, which is mainly emitted during the use of energy. 90% of the carbon reduction target work depends on energy conservation. “The energy saving target of the “12th Five-Year†petrochemical industry is that the energy consumption of industrial added value per million yuan in 2015 was 15% lower than in 2010. Therefore, as long as the energy saving target is achieved, the carbon emission reduction target will be basically achieved.†Fang Xiaoyu, vice chairman of the China Chemical Industry Energy Technology Association, told reporters that since the "Eleventh Five-Year Plan", the petrochemical industry's energy-saving work has achieved remarkable results, the industry's industrial added value energy consumption has decreased by 35.8%, ethylene, ammonia and other key products The comprehensive energy consumption also decreased by 11.6% and 14.3%, respectively, and the energy consumption of some products has reached the international advanced level. "Therefore, further significant energy saving and emission reduction will not be small for enterprises and industries. However, in order to achieve long-term development, in order to accomplish the country's carbon reduction task, we must further explore the potential for energy conservation and increase the degree of energy conservation," Fang Xiaojun said. Fang Xiaoyun said that to achieve the goal of energy saving and accomplish the task of reducing emissions, the most effective way is to carry out energy-saving technological innovation and promotion in all directions. According to him, the China Chemical Industry Energy-saving Technology Association is implementing energy-saving technology implementation plans for zero-distance interviews of enterprises in the “look-and-see-the-cut†way. It has conducted energy-saving technical diagnosis for Yanshan Petrochemical, Tianjin Petrochemical and many other large-scale chemical companies and proposed energy-saving technological transformation. Suggest. At present, some energy-saving technologies have received relatively good results after the implementation of these enterprises, such as industrial furnace blackbody technology, double alkali desulfurization and so on. At the same time, many companies in the industry stated that it is necessary to complete the “Twelfth Five-Year Plan†energy-saving mission to achieve carbon emission reduction targets. It also needs to include a large variety of energy media in the petrochemical industry, a large amount of energy consumption data processing, and scattered locations of energy-using equipment, resulting in inconvenient management. The characteristics of accelerating the realization of decentralized control and centralized management of energy systems. In this regard, the government needs to provide more guidance and support, establish more low-carbon pilot demonstrations, and cultivate the industry's low-carbon benchmarking companies.
Die casting(Aluminium Die Casting) is a metal casting process that is characterized by forcing molten metal under high pressure into a mold cavity. The mold cavity is created using two hardened tool steel dies which have been machined into shape and work similarly to an injection mold during the process. Most die castings are made from non-ferrous metals, specifically zinc, copper, aluminium, magnesium, lead, pewter and tin based alloys. Depending on the type of metal being cast, a hot- or cold-chamber machine is used.
The casting equipment and the metal dies represent large capital costs and this tends to limit the process to high volume production. Manufacture of parts using die casting is relatively simple, involving only four main steps, which keeps the incremental cost per item low. It is especially suited for a large quantity of small to medium-sized castings, which is why die casting produces more castings than any other casting process.[1] Die castings are characterized by a very good surface finish (by casting standards) and dimensional consistency.

Two variants are pore-free die casting, which is used to eliminate gas porosity defects; and direct injection die casting, which is used with zinc castings to reduce scrap and increase yield.
