It used to be a luxury machine and no one used it, but now it can be seen in almost every families. The developments of this industry not only raise its own value, but also witness the huge changes of the economy in our modern society. Though this development, we are just like putting our selves into the wheels which are continuously driving us to the success. In 1978, the requirements to the air condition are just at a extremely low level. When it es 1997, people39。s living standard increases dramatically. Lots of people are being richer than ever before. They can easily afford to all kinds of modern home appliance. The air condition which is one of the most famous one are being more and more used in normal lives. The reports said that in down areas, the percentage of people who have air condition is increasing sharply those years. Also in other sub urban areas, the consume on this machine also rises steadily every year. During the following years, this development didn39。t stop. The statistics reveals that in 2020, the percentage of people who has been holding an air condition in 30 cities of all country has rated at %, which is 15 percent higher than that of 1998. In big cities like Shanghai 、 Beijing and Guangzhou, this percentage even picked at more than 108%. Also these developments of air condition make the manufacturing its parts such as Central air conditioning temperature controller turntable being an essential part to constitute our modern industry of air condition. These parts are mostly made by precise moulds. Because of various history reason, molding industry of china and the industry develop now are still not adapt very much. Is in the aspects of designing to make the technique and produce the ability regardless, still manage the level aspect, the molding tool industry can39。t meet the demands all and far and far, the species, quantity and the production periods of its serious influence industry product, weakened its petition ability in international market. In recent years, our country the molding tool imports the range to present to descend significantly, and have over hundred million dollar’s exit sum. Large, plications, nicety, the longevity life, also ascend the new step year by year with molding tool efficiently. More and more high manufacturing technique level’s progressive die has appeared. Hurtle to press the automatic line and hurtle the technique to also get the extensive application automatically. The technique of the molding tool profession of our country has developed very fast, the molding tool national product turn to have already very pleased result, it will let our country in the international market of exaltation of petition ability and prehensive national strength rise to promote the function.
