First, a mechanical press cuts out disks from a metal sheet, decoiled from a decoiler. The thickness of the sheet can start from 1 mm up to 3 mm in some extreme cases. The disks are put into the mold of the hydraulic deep drawing press that draws the disk into a fire extinguisher. The part that comes about looks like a pot.

For a fire extinguisher there usually needs 2 action hydraulic press where the first press will draw a pot from a disk and the second press will draw the final fire extinguisher from the pot. As those pots are transferred from one pres to the another, we advise either automation between the presses or both presses shall stay near to each other for an operator to move the pots from the first hydraulic press to the second.

The disk cutting process with an eccentric mechanical press takes nearly 1 second per disk but the way that a hydraulic press works is a little bit different and it takes much more than the time the eccentric press takes.

Usually, the first drawing with a hydraulic press takes 15 seconds for the first drawing and the second and the third drawing together, as carried out sequentially within another hydraulic press may take up to 20 seconds. After the second and the third drawing is complete, the part is moved from the hydraulic press to the edge cutting and trimming machine
