At present, China's mold industry has begun to take shape, and the industrial system has basically taken shape. On the one hand, leading companies in various mold sub-industries are already present. Leading companies can play a role in leading the industry's progress. On the other hand, the structure of mold products is more rational.
According to the product's materials and forming methods, the mold is divided into 10 categories, including stamping dies, injection dies, die casting dies, forging dies, and glass dies. At present, the product structure of China's mold industry is basically the same as that of developed countries.
It is understood that the development of China's mold industry in 2013 was significantly better than in 2012. However, our country’s economy is in a critical period of transformation and seeking a new equilibrium in the growth phase. The mold market demand began to pick up, and the trend of development is becoming clearer. It is estimated that the growth of China's consumption and exports in 2013 will be approximately the same as in 2012, but investment growth will face downward pressure. Although the annual GDP growth rate is expected to maintain an 8% or so Large, but the manufacturing industry is affected by overcapacity, rising costs, low profits, etc., and growth expectations can only be cautious and pessimistic.
With the current domestic technologies and capabilities, although the domestic mold industry can meet most of the company's mold needs, but because the industry is still generally lack of independent innovation capabilities, some companies' individual mold processing requirements are difficult to meet.
In addition, due to the enterprise system, mechanism and management reasons, including the assembly quality and comprehensive service level is not high, especially after-sales service can not keep up with and other issues are still a serious impact on the development of China's mold industry can not be ignored existence.
At present, China's mold industry is now in a period of development and transformation, and it will inevitably show many problems. However, next year, the domestic mold industry will inevitably have a deeper level of improvement.
Cold Dryer filters
Describe:
The cold drying filter is a kind of cleaning and drying parts to filter the moisture and impurity in refrigerant and keep the refrigeration system clean and dry. When refrigerant contains water and impurity, the system is prone to clog up, ice blocking and so on, thus blocking or partially blocking the refrigerant cycle, which makes the refrigerator lose its refrigeration capacity or the refrigeration effect becomes worse. The drying requirement of refrigeration system is very high and the moisture content in refrigerant per 1kg should not be higher than 20mg. so the drying filter plays an extremely important role in the refrigeration system.
From the aspect of appearance, there are two types of dry filter: single tube type and double tube type. The single-tube drying filter has only one inlet and one outlet. The double-tube drying filter has two entrances and one outlet.
Characteristics:
Water vapor in the air is condensed into water droplets through the principle of cooling. A small amount of oil and impurity can not be removed, so it is necessary to install the water vapor in the air.
The main function of drying filter is to absorb moisture and filter impurities. The dry filter has molecular sieve and filter net, which can absorb and filter the moisture, metal powder and dust contained in the refrigeration system, so as to clean the refrigerant or the compressed air.
