The special type is cast as the important component of casting the trade, has got the development at full speed in the last few years, its high performance offered, high-quality accurate casting Become such important trade indispensable shaping methods as the automobile, spaceflight aviation etc. Promote special type cast equipment directly to accurate casting constant increase of demand Development.
It was magnificent and brilliant that our country had created the casting industry in history. Making common people exclaim superbly so far of three generations'' bronze ware of Xia, Shang and Zhou dynasties. But our country casts at present Compared with foreign countries there is very big disparity in the engineering level of the trade, it is restricting the development of national economy seriously. It is an important component of the manufacturing industry to cast the trade Play an important role to the development of national economy and enhancement of defence capability. Casting is automobile, petrochemical industry, steel, electricity, shipbuilding, textile, equipment Foundation of pillar industry of making etc. but advanced casting technology advanced important content of manufacturing technology. Relevant statistics show, 2002, our country The output of the casting is 16,260,000 tons, has already occupied the first in the world for 3 years in succession. Though the output of casting of our country has already leapt to and cast the big country, from comprehensive quality, material structure, such respects as cost, energy consumption, benefit and cleaner production etc. are seen and far from casting the powerful country.
Since the foundation of the state, after more than 50 years of construction, the manufacturing industry has already laid a better foundation, the industrial added value of the manufacturing industry accounts for 35.75% of GDP. At present, Our country has been second only to the manufacture big countries of the United States and Japan, morality already, but compared with developed country, our country casts trade disparity, display in the comprehensive quality of the casting mainly, Cast such basic conditions as the production technology and technical equipment etc. As regards precision of size, the castings of our country are general lower by 1 grades than that of the developed country, roughness of surface Thicker by 1 grades than developed country too. Such as the roughness of the cylinder block of the engine, our country is that 25 microns, like 100 microns is 12.5 microns like 25 microns abroad. Casting Such basic conditions as the craft technical equipment etc. our country is greater too with developed country disparity generally. In view of model and making core, the developed country is raw in enormous quantities Produce medium and small-scale casting mould of casting, adopt high urgent real high pressure, high speed of rate penetrate high-efficient assembly line of pigeonholing etc. mostly, adopt the resin and sand to make core. There is little our country Count large-scale enterprises and adopt the foreign and advanced model, make core craft. Because of the disparity on the craft and on the equipment, make the precise casting of our country not precise, leave the developed country Near to have surplus cast to have a long way to go technology, especially in special type, accurate shaping craft and developed country disparity heavy.
Nearly there are 24000 casting enterprises of our country, compare with developed country in enterprises more, the specialization degree is low, it is low to intensify the degree, the labor productivity is relatively low too. 10 tons of outputs of average annual each person in our country, height of specific labor productivity one is 30 tons. USA, Germany are from 46 tons to 60 tons, Japan is from 60 tons to 85 tons ,Disparity is obvious. Average every factory of our country produces more than 500 tons of castings per year, but Japan is 4700 tons, Germany is 4300 tons, USA is 4280 tons. Casting machine The developed country is much lower that the tool instrument level compares with precision of the mould, performance, forming a complete set, dependability level, a lot of key one, mould need importing.
After China joins WTO, the domestic protective measure is cancelled, importing the expenses which are cast the equipment will drop, advanced person''s import volume of casting equipment must increase Can enter the Chinese market second-hand equipment imported to restrain from in a large amount too in the past. At the same time because of the relaxation of the investment condition and improvement of the investment environment, it will be favorable Cast equipment enterprises to enter China and set up the joint-venture or the proprietorship in foreign countries, thus bring the severe challenge to domestic casting equipment enterprises.
Cast the manufacturing enterprise of the equipment and adopt relevant advanced technology only extensivly and rapidly at home, improve the technical feature of the products, quality, lower costs. Same When form because various kinds of the producing original fittings to be specialized manufacturer, offer for casting equipment enterprises high-quality part source of. In addition, it is that our country casts that " production, teaching, research " is combined Make the key link of equipment development. In the current era of knowledge-driven economy , only could turn the newest scientific and technical result into rapidly through the combination of the three Productivity, or independent intellectual property right, strengthen one''s own competitiveness in the international market, occupy a tiny space in keen competition. We in this respect Still have a large amount of work to do.
This report organizes statistics of the association according to such such trades as the government organs of the country and mechanical industry federation etc. as State Statistics Bureau, General Administration of Customs etc I to 2004 The country has cast production, sale, market situation, trade structure, the products and imports and exports situation of the equipment trade etc. and made an exhaustive analysis, it is relevant to consult at the same time The development trend of the trade, cast the development of the mechanical manufacturing and make prediction to our country in the future.

European Union determines to impose the antidumping tax in originating in such products as the castings of China etc.
