Zinc Die Casting Valve Parts are a metal forming process in which molten zinc metal is put under pressure and injected into a die.
Zinc are alloys that have high strength and hardness, outstanding corrosion resistance,full recyclability, mechanical properties, high thermal and electrical conductivity and strength at high temperatures. Zinc alloys possess high dimensional stability for complex shapes and excellent thin walls. The cost of raw material is low.

Into the 1980s, due to the rapid development of the national economy, the continuous expansion of foreign trade, the people's living standards have been significantly improved, and the packaging requirements for products have become higher and higher. It is imperative that packaging be mechanized and automated, thereby greatly promoting the development of the packaging machinery industry. The position of the packaging machinery industry in the national economy is increasingly important. In order to promote the rapid development of the packaging machinery industry, China has established a number of management agencies and industry organizations. In December 1980, the China Packaging Technology Association was established. In April 1981, the Packaging Machinery Committee of the China Packaging Technology Association was established, and later China Packaging Corporation was established.
Since the 1990s, the packaging machinery industry has grown at an average annual rate of 20% to 30%, and the growth rate is higher than the average growth rate of the entire packaging industry by 15% to 17%, which is 4.7 percentage points higher than the average growth value of the traditional machinery industry. The packaging machinery industry has become an indispensable and very important emerging industry in China's national economy.
Currently, there are about 1,500 enterprises engaged in the production of packaging machinery in China, of which nearly 400 have a certain scale. There are 40 types of products and more than 2700 kinds of products, among which there are a number of high-quality products that can meet the needs of the domestic market and can participate in the international market competition. At present, China's packaging machinery industry has a group of key enterprises with strong development capabilities. They are mainly composed of the following aspects: After the technological transformation, some of the mechanical machinery factories that produce stronger packaging machinery are developed; Higher township enterprises. In order to improve the technological level of the packaging machinery industry, the National Institute of Information Technology, a group of packaging machinery research institutes, has established an information institute. Some colleges and universities have successively established a packaging engineering profession, which has provided powerful force for the development of the packaging machinery industry in China to catch up with the world advanced level as soon as possible. Technical guarantee.
Although China's packaging machinery industry has developed rapidly, compared with developed countries, there is a large gap between product variety, technology level, and product quality. Developed countries have applied microcomputer control, laser technology, artificial intelligence, fiber optics, image sensing, industrial robots and other high-tech technologies to packaging machines. These high-tech technologies have only just begun to be used in China's packaging machinery industry; China's packaging machinery The product variety gap is about 30% to 40%; there is a gap between the performance and appearance quality of packaging machinery products. Therefore, we must take strong measures to further accelerate the pace of development of the packaging machinery industry and strive to catch up with the advanced level of the world as soon as possible.
We have professionally produced Zinc Die Casting Valve Parts nearly 7 years. The parts have a great property of high quality, high precision, reasonable competetive price. our products are very popular.
The development of domestic packaging machinery industry. Before liberation, China's packaging machinery industry was basically blank. Most of the products are not packaged, and only a handful of products are packaged by hand, so no mechanization of packaging is available. Only major cities such as Shanghai, Beijing, Tianjin, and Guangzhou have beer, soda filling machines, and small cigarette packaging machines imported from Britain, the United States, and other countries.
