The French government has actively promoted the innovation and development of the chemical industry, actively researched and developed chemical products adapted to the markets of emerging countries, and at the same time studied and solved the possible environmental pollution in the production and sale of chemical products, and achieved positive results. In 2011, the output value of the French chemical industry was 77.1 billion Euros, of which organic chemicals, pharmaceutical chemicals, minerals, special materials, and daily necessities accounted for 35.4%, 3.6%, 13.2%, 21%, and 26.8%, respectively. Ranked fifth in the world after China, the United States, Japan, and Germany. The chemical industry employs 172,000 people.

Aluminum Die Casting

In the entire die casting industry, the use of aluminum alloy die castings accounts for the highest proportion. Aluminum die casting parts are mainly used in industries such as home appliances, motors, communications, automobiles, and electronics. Some are also used in parts of aviation, navigation and some equipment. Using die-casting processing, the dimensional accuracy of die casting part is relatively high, the surface finish is relatively good, the strength and hardness are high, and the productivity and material utilization rate are relatively high. There are also some problems in the die-casting process, such as cracks, which requires us to anneal the die-casting mold regularly to eliminate the stress in the cavity, or sometimes there are cracks on the surface of the cavity, the surface is polished to remove cracks. And the mold is preheated evenly.
