As a rule, one ironing operation is sufficient for calibrating precise parts. Long, thin walled parts are generated in one stroke by relatively large reductions in the wall thickness on presses with long stroke length and several ironing rings arranged consecutively. The blanks are pulled through the die with the punch. In one cycle, the wall thickness is reduced precisely to the required dimension, the ultimaManufacturing CNG gas cylinder tanks from blanks offers many advantages. Blanks are easier and less expensive to manufacture than seamless precision tubes. In addition, they have thinner bottoms compared to containers forged from a solid block. High surface quality is guaranteed by the integrated ironing process. Fully automated production processes and fast changeovers maximize productivity for the system.
te shape is created and the surface is smoothed.
