Mold industry began to show radiation effects


According to statistics, the output value associated with mold industry sector output ratio of about 1:100, or 100 million yuan each mold about 100 billion can stimulate the development of related industries, known as the "golden key" of the mold industry, the overall development trend a reflection mirror of the development of related industries.

Mold industry began to show radiation effects

China's mold industry has achieved rapid development in recent years, China in 2005 dies sales of 61 billion yuan, up by about 25%. It is understood that our mold product structure was further become more reasonable, with a large high-tech, precision, complex, long-life mold of share from 20% to 30%. Also, some mold companies continue to improve the level of equipment, technology has improved continuously, production capacity has been strengthened, mold showing a new trend.

An industry of "radiation" and the Industrial Park to promote the construction of inseparable, mold growth began to build its own chain. China Die & Mould Industry Association executive vice president Cao Yanan introduced to promote clustering, and gradually form a reasonable division of labor, complete and perfect industrial chain mold close collaboration to promote mold and related areas as well as the development of manufacturing industry chain has become a trend.

Currently, many local governments recognize that the development of manufacturing tooling industry on the importance of the mold industry is further concerned that the construction of industrial parks in China mold is "heat" to start. It is understood, Ningbo Yuyao, Ninghai and the Kunshan, Suzhou Park has expanded in such mold; new industrial park is stepping up construction of mold, the mold industry in Chengdu to promote the establishment of the Office, Chongqing, Dalian, Shenzhen, Suzhou, which have a mold park; other Shenyang, Xian, Shanghai, Ningbo Beilun, Zhejiang Huangyan and other places are actively preparing for the establishment of die park. Some Hi-tech Park within the mold has been a considerable amount of business, as there are more than 40 high-tech zones in Tianjin Mould Company. The mold pattern of industrial parks will allow mold to establish the industry further escalation of radiation effects.

Automotive, IC significantly stimulate growth of mold industry

Mold industry and other related industries are mutually reinforcing, making mold industry constantly focus on new market demand to achieve their expansion, while the automobile industry, information industry has become a driving engine of growth mold industry.

The latest statistics show China Association of Automobile Manufacturers, domestic car sales in 2005 reached 5.9 million, ranks second in the world. China's auto consumption in 2001 has only 2.73 million, accounting for 4.3% of the global automotive market, while the proportion in 2005 raised to 8.7% this year, auto market will maintain a 15% increase in annual car sales will reach 640 10,000 to 6,600,000. Auto Parts This "cake" in the market bigger than the vehicle, because it support vehicle, used car maintenance, non-automotive engine supporting three areas, and provides international procurement, have predicted China's domestic demand for cars in 2010 components as much as 180 billion yuan. Deputy Secretary General of China Die & Mould Industry Association, Ke Qin stressed that more than 95% of them have to die to make. Such a huge demand for the market, will significantly drive components for the automotive industry to provide equipment industry, the rapid development of mold.

In the information industry in 2005, China's information industry will reach 1.14 trillion yuan, sales income of 3.4 trillion yuan, up 27%, mobile phone, color TV, laser disc, laptops and other major products increased by more than 30%. "During" the rapid development of China's information industry will continue, so our supply of IT will continue to die.

In addition, small household appliance market, agricultural machinery, food machinery, construction industry development will promote the rapid development of mold industry.

Equipment, standardization should scale new heights

Although China's mold industry has made great progress made great progress, but can not be avoided is that the overall level of China's mold industry is still relatively backward, and behind the advanced countries in general 15 years -20 years, also need to catch up.

In the mold industry, upstream and downstream sectors in supporting and processing equipment, mostly imported, while the machine is a weak link. Cao Yanan said processing equipment in 2004, machine tool imports about six billion U.S. dollars, of which application tool and die industry accounted for most of this is also reflected in this field have yet to be refueled. Deputy Secretary General of China Die & Mould Industry Association, Ke Qin stressed that domestic manufacturers should pay attention to the equipment manufacturing industry attention to the needs of mold industry, domestic equipment manufacturers such as Shenyang Machine Tool Group has been aware of the mold machine "value added" potential, focusing on the processing center, CNC machine tools and other equipment development and production. The machine towards high speed, precision, high-performance professional, systematic and complex in the direction of development of domestic manufacturers to bring new topics.

Field in the mold standard parts, domestic production has been large mold standard parts mainly mold, oriented pieces, red top, car oil guide plate mold, wedge, etc.. At present, China mold standard parts for use in mold coverage only 40% in Europe and the United States and other countries can reach 70%. Ke Qin pointed out that the industry standard to become the new trend of mold, die mold industry to expand the varieties of standard parts, to improve the accuracy, increase concentration of production to achieve mass production.

It is understood that show domestic mold industry development trend and the trend of the Eleventh International Mould Technology and Equipment Exhibition will be held May 8 in Shanghai. Qin Ke introduction, the size of the current international model show the best previous record, exhibitors will also break through 1200. Held in conjunction with the "advanced mold manufacturing technology symposium," German Die rich forums and trade activities will further promote technical exchange and die industry in domestic and foreign exchanges and cooperation, as China's mold industry in the coming year and bring new ideas for future development.

Mold industry related industries need to improve strength

"Eleventh Five-Year Plan" period, China's mold industry will further adjust the structure, market development, strengthening management and improving the level of our country and die industry as a whole to a new level, but this does not just die industry, "a matter of . "

Mold industry and other industries can use to describe interdependent, and thus improve the overall level of mold industry and related industries are closely related. At present, China mold products mainly to middle and low-based, low-tech, high profile mold most to rely on imports, one of the reasons is because of lack of core technology related industries. If the field of IC packaging mold, because the overall level of the domestic IC industry, as well as foreign technology blockade why, making it difficult starting point IC packaging industry, the development of mold. Thus, in the IT industry, the automotive industry product demand driven mold growth, improve our country in the IT industry, the auto industry's overall strength is essential to win.

Tongling 3 Jia Technology Co., Ltd. Deputy General Manager of cotinine Yamada: toward automated semiconductor packaging mold

Semiconductor packaging requirements of the mold and die industry is: either the finishing mold, the present electronic products are continuously integrated, compact, high-end products tend to size is also smaller and thinner package body, which is packaging requirements growing, high precision mold.

Plastic molding process after the production of semiconductor devices is extremely important means of technology, single-cylinder general application packaging technology, the package object, including DIP, SOP, QFP, SOT, SOD, TR class discrete and chip tantalum capacitors, inductors , bridge circuits and other products.

Today packaging technology continues to develop. Die size, chip area and packaging area ratio of more and more close to 1, I / O count increased, pin spacing. Indispensable to the development of advanced packaging technology of electronic equipment, industrial molds, multi-injection of the first package mold (MGP), Automatic punching molding system, automatic packaging systems, high-tech new products to adapt to this demand, three good these products are launched .

Multi-injection head package mold (MGP) is an extension of single cylinder mold technology is now mainstream products packaged die. The multi-barrel, multi-injection head packages, balanced flow advantage is that it can realize the close-filled, high resin utilization, packaging process stability, product quality and good packaging. It is suitable for SSOP, TSSOP, LQFP and other multi-row, small pitch, high density integrated circuits, and SOT, SOD and other micro-encapsulated semiconductor device products.

Automatic punching molding systems are integrated circuits and semiconductor automation equipment after the molding process. High-speed, multi-functional, versatile development of the system can meet all kinds of molding lead frame carrier.

Semiconductor packaging mold the future direction of development is to be more accurate, more high-speed packaging molds - Automatic packaging mold development. Automatic molding system is integrated circuit packaging process after the high-precision, high-automation equipment. System set up multiple plastic work units, each installed module cassette MGP model, a number of units according to the preparation of the order package, the whole set of loading, loading, packaging, cutting, clearing model, in addition to plastic, to close material in one. The rapid development of technology abroad, have been a foil cover packaging, dispensing plastic technologies to meet all kinds of high-density, high pin count packages of products.

With the rapid development of microelectronics, semiconductors, plastic molding process after the application of technology continues to improve equipment, automation has become an inevitable trend. Three good as the first domestic mold industry companies, will keep a close eye in the world of advanced technology to speed up the process of e-mold-made.

Wuxi Sheng Mould Co., Ltd. Deputy General Manager Zhu Xiaobing: connector for high mold manufacturing

Connector as a port for transmitting signals in various industries such as mobile phones, computers, program-controlled exchange, home appliances, has been widely used. Foreign firms now account for the high-end connector market, domestic manufacturers still dominated by low-end, in part by the connector mold industry levels. Related to injection mold for the connector, terminal stamping, plating and so on, Guosheng stamping dies mainly to do terminal products, including mobile phone SIM card terminal mold, terminal die STOCK computer CPU socket, electrical type terminals molds.

Mold in the connector terminal, the domestic manufacturers to lower end of the main and country areas containing mainly for high-end. Guosheng current international companies such as AMP connector AMP, Molex, and other famous manufacturers supporting.

Connector on the mold manufacturing industry demanding: First, the need for high levels of mold design, the terminal because of different shapes, connectors have different structures, how to conduct the design is very important, if the irrational structure will lead to product failure . Second, high-precision equipment, connectors, terminal equipment, high precision machining requirements, foreign equipment precision can reach 卤 0.002mm, and general domestic equipment can only reach 卤 0.01mm. 3 is a good basis for processing technology. Mold needs a good connector design, equipment, technology the perfect combination of the three. At the same time, this equipment package of higher, technical barriers to higher Guosheng advanced CNC surface grinding, automatic optical curve grinding, Wire EDM, machining center, combination of devices for production.

Connector Terminal mold the future demand is increasing, this is the connector interface, small size, high data transfer rate trend 浣跨劧. So that the mold equipment, materials, quality requirements are higher, the use of the punch of red die speed has reached 500 r / min -3 000 r / min, which put forward higher requirements for mold companies.

Guosheng remained advantage is that: First, the ongoing investment in equipment, because the investment to purchase the most advanced equipment in order to introduce the highest level of technology, technology, research and innovation. At present the necessary connector tooling wire cutting, 4 axis machining equipment manufacturers in China have been manufactured, although the precision, stability, there is still a gap, but it is a good start. The second is to provide training to go out and inviting way, and constantly improve the standard of the country Sheng technology.

In addition to mold the connector terminal, the country's domestic air-conditioning heat sink containing mold, the motor dies, gun dies, integrated circuit die in the market are also popular. Guosheng planned 5-year period, among the top five manufacturers in the world die. In another 10-15 years, in line with the world advanced level.

Perspective: The mold industry should pay attention to digital innovation, network

China Die & Mould Industry Association executive vice chairman and secretary general Cao Yanan

China's mold industry's production capacity has been about for nearly 10% of the world total, ranking third in the world, behind Japan and the U.S.. But the technical situation is worrying than the level of mold technology behind many industrialized countries, the overall level of Germany, the United States, Japan, compared to lag behind about 15 years. How policy, pattern, technology, and enhance the ability of independent innovation of domestic mold industry as an important proposition mold industry.

In the innovation model, although original mold industry, integration and innovation of absorbing the main mode of three independent innovation, are also success stories, but the mold is a mechanical, electrical, optical, chemical in one of the high-tech technology products, CAD / CAM / CAE, high-speed machining, rapid prototyping, precision molding, super finishing, information network technologies have been applied and therefore are more suitable for integrated innovation. Of course, some of the original core technology innovation and the introduction of some technology absorption and innovation is also important.

To achieve breakthroughs in core technologies

Due to a wide variety of mold was used widely, it should choose the focus of innovation, the first break, lead the whole situation again. The next 5 years to 10 years, first in the market needs to be large, as in the present rely mainly on imports and can represent the direction of the car cover mold and large, precision molds for major breakthroughs. In order to rapidly improve the innovative capacity of China's mold industry and die design and manufacturing standards, a number of key technologies to break through, and applied in practical production. Mold industry around ten key technology, integrated into two major projects:

1. Mold design and manufacturing of digital technology and network services platform development and application

This includes the future direction of the industry leading die mold design and manufacturing of digital technology (including modular, integrated, collaborative design technology) and network reported that two aspects of service platform, to integrate the main innovation will be applied to innovation production, to increase the overall level of mold and core competitiveness and reduce mold production cycle, reduce production costs such purposes.

2. Car large sophisticated research and development and manufacturing of mold

This is a requirement for the rapid development of automobile industry automobile environmental protection, energy conservation, safety and lightweight, and cars need to import large quantities of mold conditions proposed. We need high-strength plate heating and plastic forming process and die and die forming technology to conduct innovative research areas, and the results used in the production, so hot Chengxing mold to fill the gaps, plastic forming molds to improve the level of change in the current import large quantities of controlled by others situation, in order to adapt and promote the development of China's automobile industry.

The key technology industries covering most of the major areas of mold, and more are common technologies, breakthroughs can be widely applied in the industry.

In policies and measures to guide

To improve the mold industry, capacity for independent innovation, industry and business in addition to their positive efforts, need the support of all parties. Particularly relevant government departments to actively guide and vigorous support to the more important.

First, government departments should work out relevant policies, strongly encourage independent innovation capabilities. First, establish a special fund to support innovation have a significant impact to improve the key technology research and development and research; the second is related to corporate income taxes, loans and so promote the use of the units in R & D investment; 3 is to guide the local government increased support for the mold industry, and promote the protection and support of local government introduced a number of local enterprises and the molds of preferential policies for technological innovation; Fourth, the development plan, rationalize, and setting reasonable coordination mechanism to promote the healthy development of the industry.

Second, the existing national key laboratories and engineering centers to enrich and improve the same time, proposed the establishment of stamping die mold National Engineering Center and State Key Laboratory of Materials.

Third, establish a national technology development center mold industry and product testing center, strengthening the development of mold and die technology product quality testing.

Fourth, strengthening personnel training. Talent is the basic guarantee of independent innovation, suggest that in support of the establishment of a training of teachers and senior personnel, especially in creative talent targeted technical training centers nationwide die while actively for Foreign Intelligence.

5, give full play to trade associations and other intermediary organizations.

Mold industry in the future development goals by 2010, large, sophisticated, complex technologies such as high levels of mold in the proportion of high-grade from the current 30% to 40%; mold exports reached more than 1 billion U.S. dollars; mold to achieve the comprehensive level of Asian art level. 2015, making China among the mold into power.

ASP.NET introduces the underlying working mechanisms



ASP.NET work on the underlying mechanism, recently discussed the garden is very hot. I believe many people have seen Mr. Rick Strahl's a classic: A low-level Look at the ASP.NET Architecture, by Rick Strahl agree, I took his article translated into Chinese, hoping to give to understand ASP.NET working mechanism of a friend a little help.

Special Note: The purpose of this article translated only to a large number of ASP.NET fans help, because my limited capacity, the paper does not place, please also criticized the correction. If you need to reprint, please retain the original English text and links. Thank you!

Summary: ASP.NET is a Web program for building a powerful platform that provides tremendous flexibility and capability so it can build any of the Web program. Many people only on high-level framework in ASP.NET, such as: WebForms and WebServices are more familiar with, so in this article, I will explain the relatively low-level knowledge of ASP.NET, and will explain how to request from handed over to the ASP.NET Web Server is running, then ASP.NET HTTP pipeline deal with these requests.

For me, to understand the inner workings of a platform always makes me feel some satisfaction and comfort, as insight, you can help me write a better program. Know the tools of any use, as well as their on how to assemble into complex part of the framework, which will make you very 瀹规槗 find Wen Ti of the solution Fang An, as well as in the Ni Xiugai and debug errors O'clock, they both looked very 閲嶈. The purpose of this article is from the bottom to understand ASP.NET and how to help you understand the request into the ASP.NET processing pipeline inside. At the same time, you will understand the ASP.NET engine core, and a Web request to end here. Many of knowledge are referred to here you do not need to know daily work, but if you understand how to route requests to the ASP.NET application code in (usually higher level), it is useful to you will .

Note: the ASP.NET engine completely built in managed code, all of its scalability is through managed code to build.

Most of use are more familiar with ASP.NET WebForms and WebServices. These high-level implementation, so much easier to build Web program. ASP.NET is designed to drive the engine, it is the underlying interface to the Web Server, for high-level Web application front-end and end to provide a routing service. WebForms and WebServices framework is built on top of ASP.NET, the HTTP address of the two most commonly used methods.

In fact, in the lower level, ASP.NET also provides enough flexibility. HTTP request pipeline run-time and provide the same capabilities, like WebForms and WebServices to build the realization, of course, these have been used. NET managed code achieved. If you need to build a custom HTTP processing platform, rather than WebForms this platform in which a lower level, then you will use all of these similar features.

Most of the Web interface built using WebForms is undoubtedly the easiest way, but if you want to customize a content processor, or the need for inflow and outflow of the contents of the special processing to do, or need a custom application, an application server interface, then use these low-level processing or modules will be better performance, as well as request processing in a real gain more control. Despite the high level of implementation, such as: WebForms and WebServices have provided similar functionality, but because they are too much for the request to add the control (resulting in performance degradation). So you can open up nirvana, at the lower levels to deal with these requests.

What is ASP.NET?

Let us start from the most simple definition, ASP.NET? I usually like to use the following statement to describe the ASP.NET.

ASP.NET is fully managed code handling Web requests using a mature engine platform. It is not just WebForms and WebServices.

ASP.NET is a request processing engine. Access to client requests it, and then through its built-in channels, the request reached an end point, in the end, developers can add logic to deal with this request code. In fact the engine and the HTTP or Web Server is completely separate. In fact, HTTP runtime is a component, you can host it in IIS on the outside of the application. Or even other services can be combined. For example, you can host HTTP runtime in the Windows desktop application (detailed information, please see: http://www.west-wind.com/presentations/aspnetruntime/aspnetruntime.aspx).

Pipeline route by using the built-in request, HTTP runtime provided a complex, but very elegant mechanism. In every aspect of processing the request involves many objects, most objects can be derived, or to extend the event interface. Therefore, this framework has very high scalability. A mechanism through which you can enter the lower level interfaces such as: caching, authentication, authorization is possible. You can process the request before or after the filter content, or simply to match the signature of the designated route client requests directly to your code or switch to other of the URL. For the same thing, different treatment can be completed, and implementation code are very intuitive. In addition, between the ease of development and performance, HTTP operation is also offered the best flexibility.

The ASP.NET engine completely built in managed code, all of the extensibility features are provided by the expansion of managed code. For powerful. NET framework, the use of their own things, to build a mature, high-performance engine architecture has become a testament. Nevertheless, it is important that, ASP.NET is the most impressive design vision, which makes its very easy to work on, and provides almost any part of them hook request processing capacity.

ASP.NET can be used to complete some tasks, these tasks is to use the IIS before the ISAPI extensions and filters to complete. Despite some limitations, but compared with the ASP has made great progress. ISAPI is a low-level Win32-style API, only its interface there is a trillion, that the procedure for large-scale development is very difficult. Because ISAPI is a low-level interface, so its speed is very fast. But for enterprise-level application development is quite difficult to manage. So, in a certain period of time, ISAPI, or other applications as the main platform of the bridge interfaces. But in any case, ISAPI is not abandoned. In fact, Microsoft's ASP.NET and IIS platform interface is through the host. NET in the ISAPI extension to communication, and then directly to ASP.NET runtime. ISAPI provides the core of communication with the Web Server interface, and then use non-managed code for ASP.NET requests and send response to client requests. ISAPI content provided by the public objects similar to the HttpRequest and HttpResponse, through a well designed, accessible interface to managed objects in the way of exposure to non-managed data.

ASP.NET from the browser to let us from a typical ASP.NET Web request life cycle starting point. Users type in the browser by a URL, click on a hyperlink, an HTML form submit (a post request), or a client program calls the ASP.NET-based WebService (ASP.NET available through the service). On the server side, IIS5 or IIS6 will receive the request. The underlying ASP.NET IIS through ISAPI extension and communication, and then, through the ASP.NET, the request is often routed to one with. Aspx page extensions. However, the process of handling the work is entirely dependent on the HTTP processor (handler) implementation. The processor will be installed to handle the specified extension. In the IIS in,. Aspx through the "application extension" is mapped to the ASP.NET ISAPI dll file: aspnet_isapi.dll. Each ASP.NET request is triggered, must be registered by one, and point to aspnet_isapi.dll extension to identify.

Note: ISAPI is a custom Web request processing in the first and highest performance of the IIS entry point.

Rely on extensions, ASP.NET to a request routed to an appropriate processor, which is responsible for processing the request. For example, WebServices extension. Asmx will not route requests to a disk on a particular page, but will be routed to the specified in the definition of additional features (WebMethodAttribute) class, this feature will identify it as a Web Services implementation. Many other processors will be installed together with ASP.NET. Of course, you can define your own processor. HttpHandler in IIS is mapped in all, and point to ASP.NET ISAPI extension, and these are all HttpHandler in web.config configuration, used to route requests to the implementation of the specified HTTP handler. Each processor is a. NET class to handle the specified extension. These processors can handle only a few simple lines of code to the Hello World, also to a similar complex ASP.NET page and the implementation of WebService. For now, just need to understand the expansion is a basic mapping mechanism, ASP.NET ISAPI in use it can get a request and then route requests to the specified processor to handle the request.
