Bladder Curing Presses
The control of hydraulic system included in the
equipment is designed such that the lower mould half carrying the
uncured rubber approaches the upper mould half with high velocity during
the first dosing stage, reducing the total closing period to minimum.
In the beginning of the pressing operation the closing speed is
slackened automatically in order to obtain slow and uniform compression
of uncured material. After laps of the ailing time, the press opens
automatically and the bladders are removed from the lower core plate by
a pneumatic device. The moulds which are generally executed according to
customer's drawings are mode of high grade steel. The two external mould
portions and the core are cured by o direct steam connection. The
presses and hydraulic power unit are delivered complete and ready for
connection, excluding curing platens. A timer for automatic press
opening after termination of the curing period as well as steam and
condensate piping's are normal features of supply.
