Reducing/Forming Hole Diameter
The reducing forming technology makes the outer diameter of the pipe end equal to the inner diameter of the forming die. The pipe end is inserted into the forming die and pressed towards the axial direction. It moves along the cavity and is thus formed. According to the size, the reducers go through the press forming for one or multiple times.

Apart from steel pipe, steel plate can also be used to form reducers with stamping technology. The stamping forming technology can also improves the production capacity. The inner surface of the stretching die is designed according to the size of the pipe end. After blanking punch, the steel plate will pass a stretch forming process.
