If you have a hydraulic press you could make a fixture to press the ball shapes...with a ball. Make a female pattern by dimpling a bottom die plate with a ball end mill. To determine what size ball mill you'd use, first figure out what the ball socket radius is on the top side, add the material thickness and get a ball mill of about the equivalent radius of 1/2 the diameter of the mating ball plus material thickness. Spot the top side pattern, press the ball into the die you made.
