So using a 100% MacGyver'd wood block compression mold (8"x4"x3") and c-clamps, I got a block of compressed thermoset after melting some LDPE (melted at 250-270F, no fumes for those concerned) and cranking around on the mold. A friend is making some steel brick molds and I'm looking into a legit press- possibly hydraulic (any suggestions for NOT the most expensive, will-fit-in-my-workspace, type presses are appreciated). No idea what the molds look like yet and unsure if they will have a overflow well or whatnot. Question is- what level of compression (PSI?) should I be aiming for to get this LDPE as dense and hard as possible... without breaking anything? I have no idea what sort of pressure I was getting with the C-clamps... as I was unable to measure hahaha. Also- anyone in Dallas have connects with UTA? I keep hearing about some professor that has been playing with recyclables and I'd like to network with people in the area. Thanks guys! Happy Mad Scientist Monday!!
