Hi there, hopefully you can point me in the right direction.

I need to make a copy of this mount currently made from plastic. Im simplifying the shape and making a small mould so what I need to know is if casting resin would be a suitable material to replicate it in being that it would be solid resin and then bonded to an epoxy pre preg part. Please see picture of the mount below and to give an indication of the size it is 25mm x 25mm approx.

Thanks in advance

you could make the part to bond into the main section from polyurethane casting resin rather than epoxy, fix a rivnut/threaded insert into the mould before casting
