Hi Guys, my name is Grant.

I am trying to find out how to work out a pressure over area formula.

I work tire industry with raw rubber that has to be cured (vulcanized in other word), I know that raw rubber needs 10kg of pressure for every square cm and a heat of 140degrees Celsius to cure.

The problem I have is that if you have a bigger area the pressure has to be more this is what I have been thought, I currently use a curing system with air bags but no matter how big the hole that is filled up with raw rubber the pressure stays the same, sorely it should be more if the size is bigger

I am trying to build a press that uses hydraulic rams to apply the pressure needed, I would like to know how I know how much pressure I must put into the hydraulic ram to get 10kg/cm2 over area, I know ALMAX vulcanizing presses use a similar system.

I donâ€™t know if you can help thanks
