Hi, have any members experimented with any of the Easy Composites range of Epoxy Resins as Injection Die material.

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

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
