When adjusting the cavity thickness, what is the gap between the peripheral resin channel, and the upper glass mold? He sits the depth gauge on the channel walls, but there must be space above that for resin to enter the fiber pack. In other words, the depth gauge reading won't be the final thickness of the panel, correct? Thanks!
Yes, you are absolutely correct. The gap between the resin channel and the top mould is 1mm and so this is taken into account when adjusting the cavity thickness.
I am not sure i completely understand the construction of this form. There should be a gap between central part (that can be moved) and outer part. How is this gap sealed?
The gap between the central plate and the outer flange is sealed with 'O' rings. These seals allow the central plate to slide up and down but maintain the necessary vacuum/pressure integrity.
I can understand your comment! However, this type of mould is often used to make rather 'special' small flat panels that are used to generate test coupons for structural analysis of composite laminates. The processing parameters and dimensional tolerances must be controlled to a very strict tolerance. Most of these moulds go into laboratory environments.

Thanks! I have thought about that but was not sure. Very nice technical design of the whole form.
Excuse me, how to continue to vacuum when the resin is cured? Can the resin not be drawn?
I'm not sure that I understand your question. I'm happy to help if you can explain a little more.
Excellent
Thanks Khaled!
Seems like a complicated machine just to make a very small flat panel.
