Have you considered having your 3 pots of molten plastic stationary and moving your molds to each individual pot and triggering a valve.
Then move the next mold (on a X Y axis) into position and repeat, should be possible I would think. That way 3 axis would be plenty, X and Y to move into position and Z to trigger molten plastic, from a stationary position.
With this setup you would not need a moving gantry machine, but rather a fixed Z axis, and a moveable X and Y.
Just a thought...... |
