Can it not be cured lower, at all? Reason being, if you can get it down to about 100 degrees, or even 120ish if you're doing a small production run, then your more regular tooling systems like EC's Unimould become an option. These are very affordable, easy to work with, and can produce very high quality parts. If the MUST cure at 130, then your options become a bit limited. You will need to be looking at something like a machined aluminium mould, machine some epoxy tooling block and make a pre-preg mould off that. You can also get high temperature tooling epoxy, like Airtech TFS5001. These are all mind bogglingly expensive options, so unless you're looking at doing a full production run I wouldn't even consider them.
