I have never used a precious plastic machine (though I would like;)) but I think I have the answer to your question by watching the videos of precious plastic: “How to finish precious plastic object” or something similar.
To make large dense cubes they make a welded mold ( outer part and a “pusher” ) which they put in the compression machine ( oven ).
I hope I helped you!
P.S. I’m French so it’s normal if there are mistakes in English.
