I have a prototyping Injection mould machine and split aluminium die blanks and my intention was to use a self-levelling (obviously high temperature/heat resist) epoxy resin to create the dies by pouring them around both halves of the original piece. I'd opted for resin as opposed to pastes given the highly detailed parts of my originals. I am intending to inject ABS and Nylon 66 (amongst others) which suggest barrel temperatures in excess of 200 degC. Looking at the datasheet for the high temp laminating resin, they state an HDT of 170degC Just wondering if anyone had any sagely advice or experience with this. As per this instructable https://www.instructables.com/id/Home-Plastic-Injection-Molding-with-an-Epoxy-Mold/ Upon reading the detail, they are recommending a TAPP Plastics resin with a quoted HDT of 165degF, so maybe I should just man up and try it - LOL

I suppose that the epoxy for the mould isn't subjected that long to these high temperatures of 200°C ?! How I would do it is filling it with the EL160 but with adding Aluminium metal powder to make them even more stable with those temperatures. Sure Matt or Warren will be able to confirm or say this would be a bad idea or give you other solutions Matthieu Libeert Founder MAT2 Composites X Sports website: www.mat2composites.com
