4. Metal spining development in different country  

America have many and excellent metal spinning companies ,the quantity and technology level is the leader in the world ,there are many metal spinning companies focous on aerospace and aviation field ,mainly companies are Cincinnati, Spinncraft, Herford.their metal spinning equipment tends to be large-scale and strong, such as the large vertical 240 spinning machine produced by Herford Company can spin the head with a diameter of 6 meters, and is mainly used in the processing of aerospace products parts and aircraft components .

With the continuous development of metal spinning technology, especially shearing spinning and metal flowing spinning technology has become more and more important in the aerospace and industry. Heavy duty metal flowing spinning is often used in the processing of missile shells, end caps, storage tank heads, cones, nozzles, pressure vessels of various spherical or cylindrical cylinders, pipe fittings and aerospace engine nozzle, combustion chamber cone, fairing, compressor disc and turbojet parts.In addition, the heavy duty metal spinning technology is increasingly common in the fields of weapons, naval ships, atomic energy, etc., including torpedo shells, periscope covers, liner, tail tubes, rocket shells, gun tubes and reactor parts.

In Europe，Metal Spinning have a long history ,Germany Leifeld was founded in 1891, Spanish DENN was founded in 1885, they are over 100 years of experience in metal spinning technology ,

The three roller metal flowing spinning and automobile wheel shearing spinning is earlier and lead the market .on the other hand ,German and Spain have many excellent CNC metal spinning process factory ,most of these companies are more than 60 years , they can supply the high precision metal spinning products in automobile ,aviation and aerospace industries .European metal spinning development is inseparable from the advanced CNC metal spinning equipment .

Japan is a country with developed manufacturing industry, they have metal spinning factory over 400，Their metal spinning factory usually employs are not more than 20 people ,but their metal Spinning technology is excellent and

China is the manufacturing capital of the world,of cause ,the number of metal spinning factory is the largest ,there are more than 5000 metal spinning factory in the south ,you can see One town in Zhongshan had an entire street of small spinning factories to make lighting shell before 2010, Now with the transfer of labor-intensive industries to India and Vietnam, Chinese metal spinning factories are reduced a lot, and more and more CNC metal spinning companies are transforming into high-precision fields ,and others invest the automatic robot replace the manual . From 2009, many companies invest the CNC metal spinning machine research and development ,CNC metal spinning technology is improving rapidly ,China reduce the gap with the world in the level of metal spinning technology , the price /performance ratio is high in China .

India and Vietnam is gradually replacing China in lighting and tableware metal spinning of labour -intensive ,their companies buy many light duty CNC metal spinning machine from China to make thin and no -precision of metal spinning product, their labor cost is very cheap ,the advantage in these industries is very obvious,

5. Famous CNC metal spinning machine manufacturing company

Nowday，there are many excellent CNC metal spinning machine manufacturing company ,the best CNC metal spinning technology in German ,Spanish and America ,more representative companies are Germany Leifeld ,Spanish DENN, American MJC, these company are design and supply many types of CNC metal Spinning machine ,the advanced metal Spinning equipment includes wheel spinning ,flow forming (three roller ), heavy duty double roller and single roller ,splitting .These excellent company promote metal spinning in the high precision and high-tech industry has been rapid development . such as oxygen and hydrogen tank tube spinning ,automobile wheel shear spinning ,aerospace components three roller metal flowing spinning .

Even though the rapid development of metal spinning in China after 2008, there is always a gap of between China and Europe ,United States in CNC metal spinning equipment . the advantages of Chinese CNC metal spinning machine is cheaper than Europe and America ,so the equipment still has great requirement in some mid-range manufacturing industries .Chinese Okay ,Prosper ,Denlis CNC metal spinning machine is gradually mature ,it takes a lot of changes to Chinese metal spinning industries .

6. Automatic loading and uploading development

Automatic loading and uploading can increase the production efficiency and reduce the labor based on CNC metal spinning . this market demand mainly comes from three aspects ,At first ,large orders of production need to reduce the labor costs , such as lighting , tableware ,home decoration .
