Mold is an indispensable and important equipment in modern industry. With the development of new and high technology, an increasing number of machined parts and products are replaced by moulded parts, which means the great potential of mould market. According to customs statistics, in 2000, China imported dies of 977 million dollars, equivalent to 8 billion yuan. The market of tungsten carbide dies increases with the increase of the total output of tungsten carbide.

 

 

1, Tungsten Carbide Anvil

Presently, the annual output of synthetic diamond has reached 600Mg (0.3Gcar). According to the production of 2000g (10kcar) artificial diamond consumption top hammer 10 kg calculation, the annual consumption of tungsten carbide anvil is about 3000t. If we consider the progress of technology, the annual consumption will be 1500 or 2000t.

 

2, Tungsten Carbide Drawing Die

Steel output in China has exceeded 100 million tons, and the output of wire rod has reached 18 million tons. With the rapid development of copper and aluminum wire rod, the demand of wire drawing die will account for 6%-7% of the total output of tungsten carbide, which should be around 500t. Considering technological progress and partial replacement of steel bonded tungsten carbide, it should also be in the range of 400t.

 

3, Dies for Cold Heading, Cold Flushing, Forming and Shaping

Due to the rapid development of machinery, electrical appliances, micro motors and other industries, a large number of high-speed punches have been introduced. It is estimated that the market capacity of these dies is 100-150t.

 

4, Non-Magnetic Die

In recent years, a series of non-magnetic moulds have been developed in China. Because of the difficulty in making and high price, the promotion speed is slow. It is estimated that the demand is less than 15t.

 

5, Heat-Resistant Mould

High speed wire rod mill roll is a product with groove or hole. When working, the billet of 1000-1100℃ passes through at the speed of 70-120m/min, which is subjected to thermal stress at high temperature and high frequency. So, it is a fragile component. At present, there are more than 30 production lines of different sizes in China, and the estimated demand is 100-150t.
