Mould making for pre preg parts??

(correct me if I'm wrong) Would like lowest cure time possibly. Are there any other options in high temp mould materials? Edited 10 Years Ago by Darren

For low production tooling it will work, but if you need to make a lot of parts then it's not ideal. I would suggest just sticking to a 100 degree cure cycle, which the Unimould will handle. If you need to cure hotter than that reliably, then you're gonna be looking at other materials. Machined aluminium is an option. I've seen composite tooling for high temperatures, but you'd want to be sitting down when you look at the prices. I've used Airtech Toolfusion (can take up to 191 degrees C), but you're looking at AUD $3000 for just 4L of gelcoat. Then you need the tooling resin to go with it, which is also ludicrous money.
