"The wind power industry is experiencing such tremendous growth that the industry is facing a serious shortage of various components. The component shortages mainly involve gearboxes and bearings." ¨C from Profiting from Clean Energy, Richard Asplund 2008
This is where China Wind Systems comes in. Wind farm builders want windmills faster than suppliers can currently make them, with the bottleneck being gearboxes and bearings. China Wind Systems is focused on supplying the components to solve this bottleneck.
Forging Ahead
According to the 2007 China Wind Power Report, domestic manufacturers of wind turbine units have played a significant role in reducing wind power costs and boosting wind power development, especially with their advantage of lower product prices. As a result, major foreign players are forming joint ventures with Chinese suppliers to drive down the costs of building wind farms. Within the pool of domestic parts suppliers, China Wind enjoys the competitive advantage of its tried-and-tested forging manufacturing process. Unlike the machining process, which creates a unidirectional grain flow, or the casting process, which creates no grain flow, the forging process causes alignment and orientation of the grain flow in a direction creating maximum strength, thereby assuring maximum fatigue resistance.
We employ axial close-die forging technology in producing precision forgings. It is a new technology for producing rotary precision forgings. China Wind Systems made the forging machine itself, providing a strong advantage in machine maintenance and cost compared to other companies using foreign equipment. The axial close-die forging technology has the following features:
¢Ù Reducing material consumption, which can be reduced by 35%;
¢Ú High precision and surface flatness, reducing the cutting output;
¢Û Excellent mechanical strength;
¢Ü High flexibility; and,
¢Ý Full automatic operation.
Our forging capabilities continue to increase as we implement our expansion plans. |
