Hydropneumatic cylinder for punching raw CD-‘s

CD’s- respectively DVD’s are made on special jet molding machines with a short working cycle. The gate mark is in the disk center. After solidification the slug is punched out of the disc while it remains in the die. This is done by a hydropneumatic cylinder with spring readjustment. The force created by air pressure on the primary piston gets increased by certain piston sizes on the secondary hydraulic side by factor 7. As an option a pneumatic ejector can be integrated into the piston rod to ensure the ejection of the punched slug.
