NEW UPPER ISOSTATIC PUNCH-HOLDER
It is consisting in a magnetic upper plate with interior hydraulic system which we obtain the following advantages in the pressing process:
– Homogeneous bulk density between all cavities of the die set.
– Avoiding scratches on the lateral sides of the tile.
– Avoiding upper punches displacements
– Improving deformations produced in the tile due to differences of the charging inside the cavity
– Increasing time of life for liners and upper punches.
