You obviously have no idea how the compression molding process works. You need enough pressure to close the mold. After that IT DOESN'T MATTER!!!!!!!!

Once the tool closes, it steel against steel, so it could be one pound or one million pounds, IT DOESN'T MATTER.

Hire a molding consultant. Maybe he can explain it to you.
