China's current annual sales of tools are 14.5 billion yuan, of which the proportion of cemented carbide tools is less than 25%, which is not only far from the structure of international market tool products, but also can not meet the growing demand for carbide cutting tools in the domestic manufacturing industry. Among the tools for domestic manufacturing consumption, the proportion of cemented carbide tools has reached more than 50%. The problem of disconnection between supply and demand structure has been very serious. The consequence is that a large number of high-speed steel tools that are surplus are exported or sold at a low price, and at the same time, high-performance carbide tools However, it has to rely heavily on imports. The import volume has increased from 0.9 billion US dollars in 2001 to 450 million US dollars in 2005.
In developed countries, cemented carbide tools currently occupy the leading position of tools, with a proportion of 70%. High-speed steel cutting tools are being reduced at a rate of 1%-2% per year, and the current proportion has fallen below 30%. The proportion of super hard tools such as diamond and cubic boron nitride is about 3%.
China currently produces about 80,000 tons of high-speed steel annually, accounting for about 40% of the world's total production, and consumes a large amount of valuable rare resources such as tungsten and molybdenum. This kind of blind expansion and low-level repetition has resulted in a large surplus of high-speed steel cutters and has to be sold at low prices, which has resulted in a large number of tool-manufacturing companies having low profitability. Annual output of 16,000 tons of cemented carbide, also accounts for about 40% of global production. However, the highest added value of cutting inserts in hard alloy products is only 3,000 tons, accounting for only 20%. This situation, on the one hand, caused the lack of supply of cemented carbide tools that are urgently needed in the country, and on the other hand made the precious hard alloy resources not fully utilized.
In terms of economic efficiency, China’s cemented carbide sales revenue is about 560 million U.S. dollars. Japan is only 40% of China’s output, but its sales revenue is as high as 2.633 billion U.S. dollars, of which blade accounts for 72%, making full use of resources. The company also gained good results. China's tool industry should get some useful inspiration from it.
According to relevant information, China imported a total of 23,364 cutting tool products last year, an increase of 64% over the previous year; the purchase cost of imported cutting tools was as high as $281.6 million, an increase of 87% over the previous year. These figures show that the domestic tools are still far behind the development of the machine tool host, so it has caused the current "foreign knife" best-selling situation. With the increasingly significant globalization of the market economy, it is particularly important to clarify the gap with the international advanced level and find the development trend of the hardware tool manufacturing industry and catch up.
China has become a "world manufacturing factory", which is just an estimate of some optimists. At present, the main force of China's manufacturing industry is still focused on processing materials. The ability to independently produce high-tech products is not yet strong, and overall competitiveness needs to be improved. Where are our gaps compared to the international level?
Industrial structure behind domestic machine tools have to be equipped with "foreign knife"
Since the beginning of the new century, with the large-scale manufacturing industry in developed countries shifting to China and the domestic manufacturing industry has also accelerated the pace of technological transformation, domestic CNC machine tools have begun to enter the manufacturing sector in large numbers. Then a sharp contradiction quickly surfaced, advanced CNC machine tools, not equipped with advanced domestic tools, had to be equipped with "foreign knife." The product structure of China's cutting tool industry for several decades has finally exposed serious flaws in the new development period and dragged on the hind legs of manufacturing modernization.
According to expert analysis, the gap in our country is phased. The main performance is that the manufacturing industry is still dominated by low-end manufacturing. The added value of products is not high, only 26.23%. As an exporting country, China exports its goods mainly to labor-intensive products with low technological content. At the same time, the energy consumption of China's manufacturing industry is 20% to 30% higher than the internationally developed level.
At present, Chinese cutting tool companies have already occupied half of the market through continuous learning and strategic planning. However, in the course of development, the company still highlights several fatal problems. If insufficient attention is paid to improper handling, it will seriously affect companies. The development and advancement.
Low-tech science and technology <br> <br> stage, carbide cutting tools in developed countries accounted tool type of dominance, the proportion of 70%. However, high-speed steel cutters are being reduced by 1% to 2% per year, and the proportion has now fallen below 30%. At the same time, carbide cutting tools have become the main tool required by processing companies in China, and are widely used in the automotive and parts production, mold manufacturing, aerospace and other heavy industries, but China's cutting tool companies are blindly and massively The production of high-speed steel knives and some low-grade standard knives do not take into account the market saturation and the needs of the enterprise. Ultimately, the high-end, high-tech cutting-edge tool market has been given away to foreign companies. According to statistics, the current annual sales of cutting tools in China are approximately 14.5 billion yuan, of which the proportion of cemented carbide tools is less than 25%, but the carbide cutting tools required by the domestic manufacturing industry already account for more than 50% of the cutting tools. Blind production has already failed to meet the growing demand for carbide cutting tools in the domestic manufacturing industry. This has created a vacuum in the mid-to-high end market and it has finally been occupied by foreign companies.
Low added value
Of the 16,500 tons of hard alloys produced in China, 4,500 tons are used for the production of cutting tools, and the number is comparable to that of Japan. However, the value of finished tools is only US$800 million, which is far less than Japan’s US$2.5 billion. This fully shows that the overall production level of domestic high-performance cemented carbide cutting tools is still quite different from that of foreign countries. Therefore, under the premise that domestic companies cannot meet market demand, the demand for manufacturing will have to be solved by relying on a large number of imports. According to statistics, the annual sales growth of major foreign companies in China's high-end tooling market has reached 30%, which has exceeded the average annual growth rate of domestic tools.
Service is not connected with international
Multinational companies, such as Germany's Zongke, Japan's Jiejie, Denmark's Unimog and other tool manufacturing companies, have accumulated a wealth of production experience in the long historical development, which also determines that its service form is no longer "a hammer "Buy and sell," but goes beyond the primary sales stage that is only available to the customer's tool. Based on the customer's problems in the production process, it promptly proposes a solution, which integrates sales into the advanced form of the company's production process. It has become a common sales method for foreign companies. This is why the products produced by well-known cutting tool companies are expensive and have a market, and some Chinese enterprises are not able to win the favor of customers because of their “big pictureâ€.
The 21st century is an era of networkization and informationization. The level of enterprise informatization will become an important indicator to measure the level of modernization of enterprises. Networking and informationization can not only improve corporate office efficiency, save office expenses, and speed up response. It can also provide market information, assist enterprise judgment, and build corporate brands.
At the same time, whether to value and understand the use of media to promote itself is also one of the phenomena of differentiation between Chinese and foreign tool companies. Each time before or during major exhibitions, some well-known international companies will use the industry media to promote their own corporate brands or new products. Corporate executives are pleased to accept and attach great importance to media interviews, but some Chinese companies may be Being shy or dissatisfied and unwilling to accept media interviews and reports, eventually missed the "free" opportunity to promote products and companies.
Serious waste of resources
According to statistics, China produces about 80,000 tons of high-speed steel, which accounts for about 40% of the world's total production. However, due to the lack of accurate information on market supply and demand, a large number of high-speed steel tools have been produced, and they have to be sold at low prices, resulting in a large number of tools. The low profit of the production enterprises also seriously wasted a lot of valuable rare resources such as tungsten and molybdenum. Similarly, China has an annual output of 16,500 tons of cemented carbide, which also accounts for about 40% of global production. However, the highest value-added cutting insert production in hard alloy products is only 3,000 tons, accounting for only 20%. As a result, on the one hand, the supply of cemented carbide tools that are urgently needed in the country is insufficient, and on the other hand, valuable precious carbide resources have not been fully utilized.
With 80,000 tons of high-speed steel and 16,500 tons of carbide, the total sales volume of cutting tools produced only accounts for 15% of the global total, which fully reflects the extensiveness of the development of the industry and waste of resources. The seriousness.
Industry professionals agree that with the rapid development of the Chinese economy in the past 30 years, the manufacturing industry will surely become even stronger, and the market space will be as broad as that of the European and American markets. Therefore, Chinese companies should start from the long-term interests and cultivate in an orderly manner. Internal strength, seek for breakthroughs, bigger and stronger as soon as possible, and eventually "get close to the water and get first."
In 2009, with the heightening of the automotive market, the tool industry, which is inextricably linked to the automotive market, is also rising. In 2010, with the rapid development of the automotive industry and the aerospace industry, China's cutting tool industry faces enormous challenges and opportunities.
According to forecasts, the market for China's machinery manufacturing will continue to expand, and it will have a greater demand for cutting tools. At the same time, the cutting market is still developing at a relatively high speed. Therefore, it is urgent to accelerate the development and commercialization of domestic cutting tools. task.
Faced with the rapid development of the tool market in China, tool-related companies will accelerate the pace of technological progress and market development, and strive to do a good job in the development of domestic and foreign markets, and truly make the Chinese tool industry bigger and stronger, will be more, better, Updated tool products are available to a wide range of users.

Brief Introduction
Food Extrusion is a form of extrusion used in food processing. It is a process by which a set of mixed ingredients are forced through an opening in a perforated plate or die with a design specific to the food, and is then cut to a specified size by blades. The machine which forces the mix through the die is an extruder, and the mix is known as the extrudate. The extruder consists of a large, rotating screw tightly fitting within a stationary barrel, at the end of which is the die.
Extrusion enables mass production of food via a continuous, efficient system that ensures uniformity of the final product. Food products manufactured using extrusion usually have a high starch content. These include some pasta, breads (croutons, bread sticks, and flat breads), many breakfast cereals and ready-to-eat snacks, confectionery, pre-made cookie dough, some baby foods, full-fat soy, textured vegetable protein, some beverages, and dry and semi-moist pet foods.
Process
In the extrusion process, raw materials are first ground to the correct particle size, usually the consistency of coarse flour. The dry mix is passed through a pre-conditioner, in which other ingredients are added depending on the target product; these may be liquid sugar, fats, dyes, meats or water. Steam is injected to start the cooking process, and the preconditioned mix (extrudate) is then passed through an extruder. The extruder consists of a large, rotating screw tightly fitting within a stationary barrel, at the end of which is the die. The extruder's rotating screw forces the extrudate toward the die, through which it then passes. The amount of time the extrudate is in the extruder is the residence time.
History
The first extruder was designed to manufacture sausages in the 1870s. Packaged dry pasta and breakfast cereals have been produced via extrusion since the 1930s, and the method was applied to pet food production in the 1950s. It has also been incorporated into kitchen appliances, such as meat grinders, herb grinders, coffee grinders, and some types of pasta makers. A similar functional process occurs when using pastry bags.
Effects
Extrusion enables mass production of food via a continuous, efficient system that ensures uniformity of the final product. This is achieved by controlling various aspects of the extrusion process. It has also enabled the production of new processed food products and "revolutionized many conventional snack manufacturing processes". The extrusion process results in "chemical reactions that occur within the extruder barrel and at the die.
