Which country was the injection machine invented in?
In 1958, the first injection molding machine was born in Shanghai, and opened a new page of our own plastic machinery. But the injection molding machine produced at that time was of low technical content, and could only use general plastic to produce daily necessities with lower technical requirements, such as plastic boxes, plastic barrels, plastic basins, etc.. With the development of petrochemical industry in China, China's plastics machinery industry has gradually formed an independent industrial sector, and a certain scale, is an important part of the national machinery industry, especially since the reform and opening up, China's plastics machinery industry has been considerable development.
The oldest known record is in 1872 when J.W.Hyatt in the United States solved the problem of plasticization and molding of nitrocellulose and camphor mixtures with his "packer" (US Patent No. 13329)The first machine, called an injection molding machine, was made in H.Buchholz in 1921. It is a piston type machine. Similar to the screw press at that time. Of course, this machine is driven by manpower. The first batch of injection molding machines manufactured by Eckert and Ziehler in 1926. Although its mold locking is still manual, the injection process is done with air pressure. The machine adopts a horizontal structure, and the principle is still used today.Plastic machinery in our country started in the late 50s.
It should have been invented in GermanyIn 2008 the global injection molding machine exports amounted to $5 billion 460 million, of which Germany injection molding machine industry scale ranks first in the world, total exports accounted for more than 20% of the total exports in the world, in a dominant position in the global competition in injection molding machine.Italy and Japan were ranked second, third. The export share of American injection molding machines has dropped year by year, down from 9.8% in 2000 and 5.3% in 2008.Japan's electric injection molding machine occupies an important position in the world, of which the proportion of electric injection molding machines in North America has reached about 30%.European and American injection molding machine mainly to precision injection molding machine, large-scale injection molding machine, such as high-tech, high value-added models mainly.After years of introduction of technology and technological innovation, China machinery industry in the field of low-end injection molding machine, manufacturing level has not much difference between with the developed countries, together with the labor price advantage, the low-end export Chinese injection molding machine occupies the half of the country in the world.
