New to the site and was hoping to tap into other user's knowledge to avoid wasting time potentially. I'm looking to make my first molds for some very simple shapes. I essentially want to make some 1" thick disks with different ODs and IDs. I already have some aluminum baking dishes to set my ODs and have some other components to create my IDs. Without going into crazy detail, I'm struggling with my compression and was thinking about creating matching concrete disks that I can simple lay on top of the melting plastic inside my baking dishes. My basic questions are, do you think the simple weight of the concrete is enough force to create the necessary compression? Secondly, do you see any issues using concrete in general? I was a bit worried about the porous nature of concrete and if that would lead to issues separating the two apart after cooling. Any thoughts, guidance, or experience would be greatly appreciated.
