He hopes that the vast number of suppliers and COMAC will closely seize the historical opportunity of the development of China's civil aircraft industry, and strive to promote comm

In order to expedite the upstream and downstream links of basic manufacturing processes and help China's manufacturing industry accelerate its progress towards high-quality development, the China Foundry Association, in conjunction with the China Forging and Pressing Association, the China Heat Treatment Industry Association, the China Surface Engineering Association, and the China Welding Association, held the "21st China International Foundry Expo Press Conference and High Quality Development Salon Signing Ceremony for Basic Manufacturing Processes" in Beijing on March 15. "1+1>2" Casting Expo Blooms in Tianjin, Full of Expectations In the government work report of the National People's Congress and the National People's Congress in 2023, the country proposed new requirements for high-quality development and continuously released policy dividends to continuously promote industry transformation and upgrading. Foundry is the foundation of the mechanical manufacturing industry, and the upgrading and upgrading of the industry is related to the high-quality development of many industries, especially the mechanical equipment manufacturing industry. In the face of the market that urgently needs to be released and boosted after the epidemic, the China Foundry Association strives to accelerate industry integration and strengthen the foundation and chain. As a vane of industry development, the significance of exhibitions is even more significant. After multiple studies and extensive consultations with industry organizations and enterprises, the China Foundry Association has decided that the 21st China International Foundry Expo will be held at the National Convention and Exhibition Center (Tianjin) on May 8-11, 2023. "After four years, returning to the north and choosing Tia

The main characteristics of foundry management in developed countries are: many process control items, standard and detailed process management, and strict and quantitative control scope; Implement the process without compromise; Pay attention to development and creativity, and continue to develop high-tech castings with higher intangible value. 1. There are many process management control items, the process management is standardized and detailed, and the scope is strictly quantified The goal of casting production is to produce qualified and consistent castings with the highest efficiency and lowest cost. Qualified quality means that the casting size is qualified, without surface and internal defects, and the material properties meet the requirements. Consistent quality means that the performance and quality of each batch of castings and different batches of castings are the same and consistent. 1.1 Process management control In order to achieve this goal, we need a complete set of processes and equipment. All equipment serves the process, and the process required for any process of production must be controlled. Foundries in developed countries have established strict control scope for all projects that have been proved to be controlled in terms of science and technology and where they can be controlled. The raw materials are subject to strict inspection and control, including the composition and specification of various metal materials and non-metallic materials. The parameters in the process are also strictly controlled, such as the compaction rate, wet strength, dry strength, moisture, crushing index, permeability, effective clay content, volatile matter, burning loss, dead clay content, temperature, sand hardness, etc. Many domestic foundries do not detect the effective clay content. The content of dead clay in molding sand is high, so the moisture content is high. For example, for the chemical composition of nodular

In January, the medium and long term loans of enterprises reached a record high in the same period, focusing on the investment opportunities of general equipment. In January, social finance increased by 5.98 trillion yuan, a year-on-year decrease of 195.9 billion yuan; Among them, the medium and long-term loans of enterprises and institutions increased by 1.35 trillion yuan, an increase of 1.4 trillion yuan over the same period of last year. Since the beginning of the year, the financing demand for infrastructure and manufacturing industries has been relatively strong. In January, the PMI was 50.1%, and the manufacturing industry boomed; PPI continued to reach the bottom, down 0.8% year on year. The supply and demand sides of the manufacturing industry are expected to recover, and the investment opportunities of pro-cyclical general equipment deserve attention. We believe that the investment in manufacturing industry in 2023 is still the direction of policy development, and the growth will mainly come from the policy support for high-tech manufacturing industry, the independent and controllable industrial chain under the enhanced uncertainty of the international situation, and the equipment renewal cycle. Some enterprises released the 2022 performance forecast, and the performance of the segments was significantly differentiated. As of January 30, 188 of the 257 companies that issued the performance forecast had a performance increase. In 2022, 257 companies achieved a total net profit attributable to the parent company of 36.17 billion to 47.844 billion yuan, with a year-on-year change of -14.14% - 13.57%. In each segment, oil service equipment was affected by the expected increase in capital expenditure driven by the high oil and gas prices, and its net profit increased by 164.37% - 205.14%; Benefiting from the boom of the industry,

The world's first 10-thousand-ton casting 3D printing full-process intelligent factory - six 3D printers of the National Intelligent Casting Industry Innovation (Quanzhou) Center began trial production a few days ago. The first batch of six 3D printers began trial production a few days ago. The world's first 10000-ton casting 3D printing full-process intelligent factory - six 3D printers of the National Intelligent Casting Industry Innovation (Quanzhou) Center began trial production a few days ago. The National Intelligent Foundry Industry Innovation (Quanzhou) Center is the key project of Quanzhou (Nan'an) High-end Equipment Intelligent Manufacturing Park. It will be started at the end of 2021, with a total construction area of about 14000 square meters. After the completion of the project, it will produce about 10000 tons of high-end castings annually. The first phase of the project was completed, and a total of 10 3D printers were put into operation. At present, 6 3D printers have started trial production. Entering the National Intelligent Casting Industry Innovation (Quanzhou) Center, the neat 3D printer and digital production line are eye-catching. It is understood that the intelligent factory is mainly composed of 3D printing workshop, smelting workshop and finishing workshop, which successively completes the printing of sand cores, smelting and pouring, cooling and molding, as well as shot blasting, heat treatment, polishing and painting of final castings. Compared with the traditional process, 3D printing solves the problems of long cycle, high cost and difficulty in making curved surface and other complex components in the mold preparation process, and creates a "five no" production mode without crane, model, heavy physical labor, waste sand and dust emission, and temperature difference. In the p

Sponsored by Chongqing Economic and Information Technology Commission, Sichuan Economic and Information Technology Department, Chongqing Wanzhou District People's Government, Sichuan Dazhou Municipal People's Government and Chongqing Kaizhou District People's Government, the groundbreaking ceremony of Wanda Green Intelligent Foundry Industrial Park and the centralized signing activities of key investment promotion projects of Sichuan Dazhou Eastern Economic Development Zone were held in the Eastern Economic Development Zone of Dazhou, Sichuan Province.

On February 2, Li Hanyang, Chairman of Yuchai Group, went to Guangxi Yuchai Foundry Co., Ltd. to learn more about the resumption of production, new product development and market expansion after the holiday. In the workshop, production is busy. Li Hanyang learned about the process and market prospect of Yuchai's first outward expansion cylinder head new product, listened to the casting process of Yuchai's marine electric V-type cylinder block, and investigated the sixth crankshaft and wind power products. Li Hanyang said that China's foundry industry has a broad prospect, and Yuchai foundry industry is leading. He hoped that Yuchai foundry could use its leading advantages in technology and manufacturing to build a benchmark of China's intelligent manufacturing, capture more pearls in the global foundry field, master core technology, and promote Yuchai foundry industry to climb the world peak. Guangxi Yuchai Foundry Co., Ltd., a wholly-owned subsidiary of Yuchai Co., Ltd., was founded in 2022, formerly known as the Foundry Division of Yuchai Co., Ltd., is a supplier specializing in the production of complex precision castings such as diesel (gas) engine cylinder block, cylinder head, crankshaft, automotive chassis parts, wind power products, industrial robot products, etc. Its independently developed series of high-performance cast iron material brands such as QT700-10 and QT1000-5, It fills the gap of cast iron materials at home and abroad, and its products are exported to home and abroad.

The Financial Times reported on January 23 that the United Kingdom would propose to impose a carbon border tax on imported steel as part of the £ 600 million steel industry assistance plan and encourage companies to invest in more environmentally friendly technologies. Two insiders said that the introduced carbon border adjustment mechanism is similar to the mechanism reached by the EU last year, which will force importers to bear the carbon emission costs of foreign steel. They confirmed that British Chancellor of the Exchequer Hunter also agreed to provide customized electricity subsidies for the steel industry, which exceeded the assistance plan announced by the Ministry of Finance earlier this month.

01An enterprise, whether it is manufacturing or service, whether it is a large assembly enterprise or a small supporting enterprise, will face various problems every day. However, enterprises with different training, authorization and incentive management of employees have different abilities to find problems, methods to deal with problems and attitudes towards problems, and their benefits are also quite different. In July 2014, I had the opportunity to visit many suppliers of Anlanger. Three of them are very representative. I call them Enterprise A, Enterprise B and Enterprise C. Enterprise A has repeatedly failed to deliver goods in time during delivery. During the on-site visit, it is true that many areas need to be improved. For example, in April 2014, the inspectors of the finished products of this enterprise found that thousands of products were all scrapped, with a total value of more than 100000 yuan. For Enterprise A, these losses are significant financial costs on the one hand, and on the other hand, they cannot meet the needs of Anlanger. 02It is noteworthy that the operators have found problems with raw materials during operation. However, because the operators' wages and bonuses are based on the piecework system, these employees are more concerned about how to quickly process the blanks into finished pro

The solidification feeding mode of the casting has a great relationship with the position of the ingate. Generally, the setting position of the ingate should conform to the solidification feeding mode of the casting. Generally: 1) For castings requiring simultaneous solidification, the ingate shall be set at the thin wall of the casting, and the number shall be large and distributed so that the metal liquid can fill the cavity quickly and evenly to avoid local overheating of the sand mold near the ingate. 2) For castings requiring directional solidification, the ingate shall be set at the thick wall of the casting. If a feeding riser is provided, it is better to set the riser between the casting and the ingate so that the liquid metal can be introduced into the mold cavity through the riser to improve the feeding effect of the riser, such as nodular cast iron crankshaft, gear and cast steel gear. Sometimes, in order to avoid large shrinkage stress caused by excessive temperature difference of the casting, the ingate can also be set at the secondary wall thickness of the casting. 3) For castings with complex structure, the so-called "weak directional solidification" principle combining directional solidification and simultaneous solidification is often used to arrange the ingate position, that is, ingates are set for each feeding area according to the requirements of directional solidification, while multiple ingates are used for the entire casting according to the requirements of simultaneous solidification to disperse the punching, so that the thick and large parts of the casting can be fully fed without shrinkage cavity and porosity, The stress and deformation can be minimized. 4) When the wall thickness of the casting is very different and it is necessary to introduce molten metal into the ingate from the thin wall, attention should be paid to the use of cold iron to accelerate the solidification of the

Since ISO9001 was revised to 2015, the word "risk" has been frequently used in quality management. So where is the risk hidden in our daily quality management? Only when we know ourselves and the enemy can we win every battle! Only by identifying the generation mode of quality risk can we effectively avoid it! Product quality is the result of the comprehensive action of human, machine, material, method, environment and measurement (5M1E). Quality risk comes from the quality management system, information transmission, workflow, processing and manufacturing, product inspection and other processes and support activities. Only by identifying various risks that affect product quality can effective control measures be taken to avoid quality risk. Quality is the degree to which a group of inherent characteristics meet the requirements, and quality management is one of the systematic projects in the formation of modern enterprise systems. It develops with enterprises. Only high-quality products can support the sustainable development of enterprises, and only effective quality management can foster high-quality products. The quality management level is reflected in the actions of each employee, implemented in the ideology of employees, and crystallized in products and services. 1. Quality management system risk 1. Quality risk caused by coexistence of multiple systems The quality management system refers to the management system that commands and controls the organization in terms of quality. Each manufacturing enterprise will establish a corresponding quality management system that meets international standards, foreign standards, national standards, national military standards and other standards according to their product categories and customer groups. In order to cope with diversified product categories, enterprises need to build appropriate quality management systems according to different sit

What's your salary now? You can express your opinions! Of course, this salary does not mean a unified standard. I believe that there will be high and low salaries. The salaries of different regions and the same posts will also be different. Some enterprises have high salaries, but their living conditions are average. Some enterprises have average salaries, but their welfare benefits are very good! For example, the most common type of work in the casting workshop, the furnace worker, requires a certain degree of work experience. Although the novice master and the skilled master have no high requirements for education, their wages vary greatly. There are daily and

n their work, many purchasers often need to inquire from suppliers. I'm afraid that the supplier's quotation is one of the documents that purchasers see most. However, the quotations of each supplier may be different, and there are all kinds of quotations, unless the supplier is required to fill in the quotation template sent by itself. So, as a formal quotation, what necessary information is generally required? In general, a formal and complete quotation information should include the following contents: 1) Product Description A complete quotation must first have a complete product description, including product name, specification, and quantity. If necessary, relevant technical requirements, technical drawings, and other information should be added to facilitate clear supply. If it is a service, the scope of the service should be clarified. 2) Minimum order quantity Specify the minimum order quantity (MOQ) and minimum package specification (MPQ) of the product. Such information shall be clearly indicated on the quotation. 3) Ladder quotation Generally, prices will vary for different quantities. The more quantities, the greater the discount. Suppliers should also clearly indicate that different quantities correspond to different price ranges. 4) Price and tax issues The quoted tax rate should also be clearly indicated, or c

Mexico is an economic power and manufacturing center in Latin America. This country with a population of 128 million and an area of 1.9644 million square kilometers has always been one of the most open economies in the world. In recent years, Mexico seems to have a tendency to become a new global manufacturing center. European enterprises are optimistic about Mexico, which is "too far from God and too close to the United States", and they have invested in the country to set up factories. Asian countries also actively use their offshore outsourcing advantages to restructure the North American supply chain. Whether the signing of the US Mexico Canada Agreement replacing the North American Free Trade Agreement during Trump's term of office, or the signing of the Chip and Science Act and the Inflation Reduction Act by US President Biden in August this year, objectively speaking, all have brought changes to the development of Mexico's manufacturing industry. Chinese netizens have also recently expressed concern that "American supermarkets are becoming less and less' made in China ', and more and more' made in Mexico '". However, the analysis of international public opinion and the scholars who have studied Mexican economy for a long time have all noticed Mexico's "weaknesses". More importantly, if Mexico wants to become a global manufacturing center, it cannot do without strengthening trade with China. Four Advantages Make Latin America a Great Manufacturing Country Many people know that Mexico is a traditional agricultural country and the origin of corn, tomato, sweet potato and tobacco, but they ignor

Construction machinery is an important part of the equipment manufacturing industry, and its development level is an important indicator of a country's industrialization. At present, the construction machinery industry is accelerating its transformation towards automation, digitalization and intelligence. The emerging technologies represented by artificial intelligence continue to inject innovative vitality into the digital transformation of the construction machinery industry. The 2022 Munich International Construction Machinery Expo ended recently. This exhibition focuses on industry digitalization and sustainable development, attracting more than 3100 exhibitors from about 60 countries and regions around the world. About 90 Chinese enterprises, together with products and solutions of "China Intelligent Manufacturing", showed the latest products and technologies of China in this field, which attracted wide attention. Digital empowerment brings great changes to the industry Munich International Construction Machinery Expo is the largest and most influential professional exhibition of engineering, building materials, mining machinery, construction and engineering vehicles and equipment in the world. It is held every three years and is an important platform for understanding and evaluating the latest technologies and cutting-edge trends in the global construction machinery industry. At the exhibition, many enterprises launched intelligent construction machinery products, and digital empowerment is bringing revolutionary changes to the entire industry. In the outdoor exhibition area of Munich Convention and Exhibition Center, visitors lined up in front of the 3D concrete printing technology booth of Parry, Germany, to watch how the co

Under the new development pattern of "double cycle+double carbon", as the core industry of China's manufacturing industry, the equipment manufacturing industry is facing tremendous changes. In order to cope with the increasing industrial production costs and fierce industrial competition, the products provided by equipment manufacturing enterprises need shorter delivery time, higher quality and better service. At the same time, with the development of digitalization, intelligence and the Internet of Things, the requirements for the personalization and intelligence of equipment products are becoming higher and higher, which brings great challenges to the development of equipment manufacturing enterprises. The production process of equipment manufacturing enterprises has four characteristics: According to the customer's requirements, the R&D and production are carried out at the same time, the product process is often changing, and the production plan changes frequently; Complex product configuration and multiple BOM levels lead to complex production order release and on-site process management; The production mode is mainly based on orders, supplemented by market forecasts, with multi variety and small batch production, and there is a situation of inserting orders; The production process is mainly for machining, and then assembling various parts. Assembly is the key, and there are many processing equipment. In general, equipment manufacturing enterprises have the characteristics of complex product structure, many types of parts, long process cycle, many cooperative departments, and great difficulty in production organization. Facing these problems, simply relying on traditional management methods can not meet the needs of modern scientific management. Only with t

On July 1, Foresight Industry Research Institute released the latest global machine tool industry market research report. According to the figure of output value and proportion of major global machine tool manufacturing markets in 2020 in the report, the total output value of the global machine tool industry in the report period reached 57.8 billion euros; China accounted for 29% of the total output value of 16.95 billion euros, ranking first in the world. Not only is the total output value the first in the world, but the total consumption of China's machine tool industry also ranks first, accounting for 32% of the total consumption of the global machine tool industry. Moreover, the trade deficit of China's machine tool industry has declined year by year in recent years, which means that the domestic machine tool manufacturing level has been significantly improved. However, it still needs to be noted that although China's machine tool output value is the first in the world, the domestic high-end machine tool market is still monopolized by overseas, and the domestic machine tool market is powerless to fight back. According to the author, for a long time, China has been very dependent on importing CNC machine tools from overseas, especially high-end machine tools, almost 100% of which are imported. Until 2018, the import rate of domestic high-end machine tools is still as high as 95%, leaving only 5% or less of the living space for Chinese enterprises. So, as the largest manufacturing country in the world, why is China subject to Japanese and German enterprises in the machine tool field known as the "mother of industry"? In my opinion, there are two main reasons for this. On the one hand, China started late and its foundation is weak, leading to a large gap in technology between China and foreign countries at this stage. In the upstream of high-end machine tools are CNC systems and various key components. In the field of nu

On November 29, according to U.S. News, on the 28th local time, more than 400 groups in the United States called on Congress to intervene in the upcoming railway strike, which will cause billions of dollars of economic losses to the United States once it happens. The American Chamber of Commerce, the National Manufacturers Association, the National Retail Federation, the Petroleum Association, the Hotel Association and other groups said that the strike could occur as early as December 5. In a letter to the American Council, various groups wrote: "The risks faced by our country's economy make the national railway strike unacceptable. In the absence of a voluntary agreement, we call on you to take immediate measures to prevent the strike and the ensuing economic damage." The American Railway Federation earlier threatened to launch a general strike if an agreement could not be reached before December 9 because it was dissatisfied with a temporary wage agreement brokered by the White House, and nearly 7000 freight trains across the United States might be halted. The American News Network said that the strike caused the interruption of railway traffic or the freezing of nearly 30% of American freight traffic, which triggered inflation and affected the transportation problems of American energy, agriculture, manufacturing, health care and retail industries. The US economy may be affected, with an average daily loss of up to US $2 billion.

More than a month before the subsidy for new energy vehicles completely declined, BYD announced that it would raise the official guide price of its models from January 1, 2023. On November 23, BYD Auto released the Description of Model Price Adjustment through the official microblog, which will adjust the official guide prices of new energy models related to Dynasty, Ocean and Denza, with an increase range of 2000 yuan to 6000 yuan. The price adjustment notice for specific models will be issued separately. As for the reasons for this round of price increase, BYD explained that, according to the national policies and plans for the development of new energy vehicles, the subsidy policy for the purchase of new energy vehicles will be terminated on December 31, 2022. After that, the country will no longer grant subsidies to the licensed vehicles (existing subsidies: 4800 yuan/vehicle for plug-in hybrid vehicles, 12600 yuan/vehicle for pure electric vehicles). At the same time, since the second half of the year, the price of main battery raw materials has risen significantly. "This round of price increase by BYD has little to do with the sharp rise in the price of raw materials for power batteries." On November 23, Cui Dongshu, the secretary-general of the National Passenger Car Market Information Joint Conference, said in an interview with the Daily Economic News that, affected by the official withdrawal of subsidies for new energy vehicles at the end of this year, at the beginning of next year, there will be another round of price rise in the domestic new energy vehicle market, but the scale will not be too large. The third price increase of BYD in the year According t

There are many kinds of casting defects, and the factors affecting the quality of castings exist in each process related to casting production, as shown in Figure 1. Large castings are characterized by large size, i.e. large volume, heavy weight, more molten iron poured, relatively thick wall thickness, and some simple and some complex shapes; Castings in different fields have different requirements. The main principles to be mastered in the design and pouring of the gating system for large castings are decentralized bottom pouring (layered injection is the best), rapid pouring (more air outlet risers are added), and high temperature pouring (core exhaust is strengthened). 1. Dispersive bottom pouring Figure 2 shows the decentralized bottom pouring system. Advantages: It is conducive to filling the mold with liquid metal smoothly; Reduce oxidation of molten metal, and have less impact on the mold and core; Prevent sand washing, reduce turbulence, and reduce gas entrapment; It is conducive to the discharge of cavity gas: it is conducive to slag removal: it can avoid excessive temperature difference in all parts, which is conducive to reducing the shrinkage stress of castings, and it is conducive to reducing the deformation of long and thin castings, which is conducive to preventing crack defects. Disadvantages: if the filling time is too long, the metal liquid will contact with the air for a long time when the mold cavity rises, and the surface is easy to generate oxide skin (it needs to be overcome by rapid pouring); The temperature at the lower part of the casting is high, which is not conducive to feeding (having little effect on the gray iron castings).

Yesterday, Cui Dongshu, Secretary General of the National Passenger Car Market Information Joint Conference, made an inventory and analysis of China's automobile exports from January to October this year. In its view, China's automobile exports still have huge development space in the future. Data shows that in October, China exported 353000 cars, a 58% year-on-year growth, continuing a strong trend; From January to October, 2.62 million vehicles were exported, up 52% year on year. In retrospect, the growth rate of China's automobile exports has gradually stabilized during 2016-2020; By 2021, however, it will show a rapid outbreak, with the annual export of 2.13 million vehicles, doubling compared with the previous year. According to Cui Dongshu, the export market has risen from the previous stabilization, mainly relying on the strong performance in Africa and Europe; In 2022, the developed markets in Europe and North America will have a prominent export growth rate, while the markets in Africa and South America will show a relative decline. In terms of the region where the export manufacturers are located, from January to October this year, the export of new energy vehicles produced in Shanghai accounted for 25% of the total export of the country, with the highest contribution, which is mainly due to the strong performance of SAIC passenger cars and Tesla. The export performance of Chery, Chang'an and Geely continued to rise, which led to the export performance of Anhui, Chongqing, Zhejiang and other places. In terms of specific categories, the export models of China's passenger cars are mainly products with 1-1.5 liters of displacement; However, with the development of new energy products in China, the export of high-end elect

According to foreign media reports, General Motors has announced an investment of 45 million dollars in its Bedford aluminum die-casting plant in Indiana. The company said that this investment will be used to enhance GM's ability to produce EV aluminum castings to meet the emerging demand for aluminum from GMC Sierra EV and Chevrolet Silverado EV standardized pickup trucks. In December 2021, General Motors announced an investment of 51 million dollars in the Bedford factory, which is used to introduce new equipment to improve the capacity of the die casting factory. It is understood that since 2011, General Motors has spent nearly 456 million dollars to strengthen its Bedford casting business. The factory was established in 1942 to provide die-casting process for the cylinder block, structural parts, gearbox and driving device shell of automobiles. Its main customers are Buick, Chevrolet, Cadillac and GMC.
