British pastor W. 1791 Gregor (Gregor) discovered a new metallic element in the black magnetic iron ore. German chemist M. 1795 H. Klaproth also discovered this element when studying rutile, and named it after the Greek god Titans. American scientist M. 1910 A. Hunter (Hunter) TiCI reduction with sodium first: Preparation of pure titanium. Luxembourg scientist W. 1940 J. Kroll reduces TiCl with magnesium : pure titanium is produced. Since then, the magnesium reduction method (also known as the Claude method) and the sodium reduction method (also known as the Hunter method) have become an industrial method for producing titanium sponge. In the United States in 1948, magnesium reduction method was used to produce 2t titanium sponge, which has since reached the scale of industrial production. Subsequently, the United Kingdom, Japan, the former Soviet Union and China also entered industrial production, the main titanium-producing countries were the former Soviet Union, Japan and the United States. Titanium is a new metal. It is widely used in industrial production such as aviation, aerospace, chemical, petroleum , metallurgy, light industry, electric power, desalination, ship and daily life equipment because of its excellent characteristics. For modern metal. Metal titanium production has only been half a century since 1948, and it is a new industry that has developed along with the aerospace industry. Its development has experienced several ups and downs, which is due to the fact that titanium is related to the aircraft industry. But in general, the speed of development of titanium is very fast, it exceeds the speed of development of any other non-ferrous metals. This can be seen from the development of the sponge titanium industry in the world: the production scale of titanium sponge is 60 kt/a in the 1960s, 1 lOkt/a in the 1970s, 130 kt/a in the 1980s, and 140 kt/a in 1992. Actual production reached an all-time high in 1990, at 105 kt/a. At present, the world's sponge titanium manufacturers and production capacity are listed in Table 1.

In 1995, the market for titanium began to pick up, mainly due to the significant increase in the amount of civilian titanium such as B777 and other civilian aircraft and golf clubs. In 1996, the demand for titanium reached a new high. Experts predict that demand for titanium will continue to grow significantly in the next few years. The main reason that currently hinders the application of titanium is the high price. It can be expected that with the advancement of science and technology and the continuous improvement of titanium production technology, expansion of production capacity and management level, and further reduction of the cost of titanium products, it will inevitably open up a wider market for titanium. Plastic Injection Molding is a cyclical manufacturing process that allows for cost efficient production of large numbers of identical parts made from either thermoplastic or thermoset materials.
The injection molding process is also used to produce many packaging items including caps for water bottles, components for cars and airplanes, toys, home goods, appliances, TVs, electronic parts and medical products. These are just a few of the items in your daily life that are made using injection molding.
The plastic injection molding is a common process that is used in the world to achieve the lower price but with high quality and big volume parts. Everywhere has its application such as automotive, electrical, consumer, industry, household.
