Here are two better photos of the part straight out of the mould.. You can see the excess flange material is still on the part and it is un trimmed this really is straight out of the mould unfinished.

Very nice work

Looks flawless.  Is that 2 out of 5 now?

I had to make 7 in the end as  the first two were not really acceptable due to pinholes and release agent residues on those first two pulls from the new mould. So that one was the 5th and final one which will go out to the customer. So when I made 5 more all of those last 5 have come out well getting better and better.. It is just the release agent residue from the new mould that has stopped them from looking really good.. Now the mould has had 7 pulls and the oven now has a ramp and dwell controller it should mean less issues with them and I can now create different curing profiles for the different materials. 

Hi morepower are you using any adhesive spray to hold the fabric in place on the mold if yes what brand are you using and what application technique are you using. currently i'm using Airtac2 and i'm getting surface imperfection issues on the laminate after i demold. I'm using Frekote as my release on Epoxy mold and infusing with Epoxy resin. This is driving me nuts/crazy as i end up having to throw away the parts. any help will be greatly appreciated. 

This is a pre-preg product mate. 

Ahh great, i would love to work with this material very soon. anyway i have uploaded pictures on the following thread, any help will be greatly appreciated

Hi Tha Pop..
Sadly I have never done infusion. I have done wet lay in a vacuum bag and pre-preg. For me pre-preg is the most consistent and cost effective as rarely have any parts that could be seen as genuine scrap parts. Material costs are higher but not so high it makes the parts very expensive to make.. Also I dont need mesh or tubes or MTI hose and there is no excess resin which could bring up the cost of making parts close to pre-preg and lay up time is reduced. But you do need an oven. I made mine from MDF, chinese fan heater and a PID controller. It works perfectly and cost about £150 to build and is 1.2 meters wide x1.2 meters deep and 1m high.

I have been asked to take over a job from a company who are making some small personal water craft. They infuse them and it takes them just over a week to make them from start to finish. In pre-preg the same job would take me 3 days.  So I could make two in the same time it takes them to make one so would in the end be more profitable and even someone making parts for personal use or as a hobby is quicker to do.  I do think understanding wet lay is quite important and if you use polyester resins cheap and fast to do. I think it has helped me and I have gone from doing it as a hobby for my own bike to now doing it as a business full time and making parts for other people. If I had to do infusion yes it would save some money but the extra time is takes to do would make up the difference and possibly mean in a week I actually make less money.

I can make a complete motorcycle fairing in 2 days where doing infusion I would think it would be almost double that. Turning moulds round is minutes and the covers I have done here I do one a day which is over a £1000 order in 5 days. Each one only takes up half a day through to putting them into the oven. If I had two mould and the customer wanted 10 per week I would do that easily... I dont think I could say the same for infusion and I would still expect some rate of scrappage due to air entrapment in the weave or some minor surface blemish ect.. As long as I follow my methodology and cure them accurately I dont seem to have an issue. I had two in this first batch with problems. One was pinholes due to the new oven set up being out and one due to spider cracks in the original mould the customer sent....    

thanks morepower.
