Rubber Compression Molding

Dear all,

I have a hydraulic press of 325 ton capacity,max applied pressure=100 kg/sq.cm.

(Ram radius=160 mm,4 nos.).platen size=1200x2200 mm.

We are planning to mold rubber wall guard of size 200x2000x25 mm thick-5 cavity in a mold of size 1150x2000 mm.

ie. mould area=1150x2000=23,000 sq.cm.cavity area=5(200x2000)=20,000 sq.cm.

Will the applied pressure acts over the entire mold area or cavity area?

If cavity area:at max,100 pressure sp.pressure=325000/20000=16.25 kg/sq.cm.

Is this sp.pressure enough to mold this object?or do we have to reduce the cavity no?what is the miminum sp.pressure required to mold a rubber object(to prevent cavity unfilling).Can anybody please help?
