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.
