In order to remove the die from the die-holder many extruders use a heavy sledgehammer to knock out the die from the ring.
This method is especially risky for flat dies that have high tongue ratios and portholes that have fragile mandrels because the sudden shock of the hammer blow can fracture these areas or start cracks.
Even appliances with a pneumatic or hydraulic cylinder manufactured by an inexperienced machine shop or by the extruder himself can cause serious injury to personnel if safety codes are not followed.
It often happens that the simple die removing operation becomes complicated, above all if aluminium is trapped inside the ring or there is a misalignment during separation.
Even worse if the holder lip is damaged or if the die is damaged. At this point the entire die stack must be sent to the die shop for a long and difficult repair.
With the Die Removing Machine this task is kept simple and effective because the high continuous and uniform strength applied by the cylinder is discharged axially on the piece to be removed.
This is placed on a plate built on purpose to keep it lined up with the thrust centre.
