Review and Expectation of the Chinese Forging Industry

In 2005, the total production of forgings in China amounts to 3.26 million tons, among which about 2.44 million tons is used in automobile, motorcycle, agricultural vehicle, construction machinery etc industries, and more than 80 thousand tons of open die forgings is used in electricity, oil, metallurgy, mine, ship-building, machinery industries.
 
 
The equipment condition of Chinese forging industry is as following:
1.There are 140 sets of 8-165 MN hydraulic forging presses, among which 60-165 MN 15 sets, 25-45 MN  35 sets, others over 90 sets. More than 20 sets of presses over 1000 ton are needed in coming few years.
 
2. There are about 32000 open die hammers in China, namely 30000 sets below 1000 kg and 2000 steam/ air hammers between 1 to 10 ton.
 
3. Die forging hammers amount to 1100 sets, and maximum falling part weight is 16 ton. 20% of them have been reformed to be Chinese original created energy-saving hydraulic/ air hammers.
 
4. There are more than 3000 sets of screw presses in China, the maximum energy is 112MN, secondly 63MN and then 31.5MN.

Over 20-100 sets respectively in demand.
 
Future Trend for forging companies:
  • Global production and supply to suit the change of automobile industry.
  • Large scale production and focus on supplying some certain product.
  • Apply electronic commerce to take part in global competition.
  • Apply computer simulation to enhance R & D capacity and shorten response time.
