The advantage of rolling forge

• High Efficiency

One or two parts are finished in one rotation of the roller, 2-12 parts are finished one minute. It can save the machining cycle time also.

• Save Material

Rolling forge made by wedge rolling technology have high precision and can be made with various shapes like tapered flange or right-angle flange. It saves 10-20% material than die forging and 20-40% than bar cutting in average.

• Good Quality

The part's mechanical property can be raised by 25% synthetically resulting from complete steel fiber and the grain refining after rolling.

• Lower cost

For the above reasons, the cost can be reduced 20-40% comparing with the traditional bar machining.
