Technical Information

Hydroforming is a technique in which a pipe is set inside a die and then formed to the inner shape of the die through the pressure of a liquid that is injected into the pipe.
By pushing the material into the pipe in the axial direction from both ends while controlling the hydraulic pressure during forming, a large degree of pipe expansion is possible, since material can be added to prevent the decrease in wall thickness caused by pipe expansion.
Moreover, there is a high degree of shape fixability with little spring back, because the pipes are made to conform to the forming die simultaneously under high pressure.
Hydroforming technology enables decreases in the number of components and welds, which ultimately allows the weight of parts to be reduced.
