Method to the explosion-calibration of a mold

In the method to explosion-calibration of a mold (1), a calibration-spine is used in the mold (1), then an explosion-material is brought on the outer-face (4) of the mold (1) and fired. The inner-side (3) of the mold (1) is pressed on the calibration-spine by the explosion-force and brought to a rat...

Zusammenfassung:	In the method to explosion-calibration of a mold (1), a calibration-spine is used in the mold (1), then an explosion-material is brought on the outer-face (4) of the mold (1) and fired. The inner-side (3) of the mold (1) is pressed on the calibration-spine by the explosion-force and brought to a rated-size. The mold (1) has in the mold-wall (2) the holes (5) for coolant and measurement-elements, which extend in the long-direction (LR) of the mold (1) and go out on the front-sides (6, 7) of the mold-wall (2). Before the explosion-calibration the holes (5) are filled with a flowable material and sealed. The flowable material is prefereably an incompressible fluid and/or a bulk goods.
