The pics you posted yesterday… you didn’t put any mesh on the vacuum side to "connect " the soric core to the vacuum pump. It should have mirrored the mesh you put in the resin side. You were trying to pull the displaced air from the resin entering the bag through the cloth laminate . The laminate can’t pass enough air to keep up with the resin. You might want to control the flow of the resin so it doesn’t fly across the top and leave the mold side dry…
Thanks I’m learning the infusion method and was going off of a previous post that stated I could not have any mesh on the vacuum side and use peel ply only under the vacuum port with a small square of breather. I only had perforated peel ply and the resin seemed to just sit on top and pool. The bag became loose on the feed side where the resin was pooling. While the vacuum side stayed tight.
Yesterday I did a small part and had the same issue. It didn’t have soric sandwiched in between the layers so I assumed I would use mesh over the entire part. Same thing, the resin raced across the tip leaving the mold side dry.
Is perforated peel ply fine to use for infusion?
Any help would be greatly appreciated as this is getting tiring.
Thanks
Aahh… missed the preferated film. Ditch the film. Is the wrong sized holes and spacing and it’s beyond the scope of present project and experience. Gotta keep it simple, not yet. Put peel ply over whole part, don’t have to but we’re getting our feet wet first then we’ll strip down to what you only need on the peel ply in future infusings. …now put a strip of mesh the same size you used on the resin side on the vacuum side also.good, now put 6 inches of spirel for the vacuum side then run hose into catch pot . You are gonna need a catch pot for now. Your setup on resin side is fine. Make sure your bag is perfectly sealed then fire away. 
This is with soric …and shorten the resin spirel to around 6 inches also.
I’m not sure you’re using peel ply. That looks like perforated film to me, can you post a photo of it?
Your second part would never have worked, you can’t infuse foam core that isn’t prepped for infusion. Soric is small cells of core knitted together with fibreglass, which creates channels for the resin to flow. Solid foam core works fine, provided you punch holes in it roughly 2" apart, and then connect the holes with light scoring.
Haha, poor guy is gonna be so confused. We’ve just told him to ditch the infusion mesh and spiral on the vacuum side, something I stand by. It’s a tiny part, the mesh and spiral on the vacuum side are unnecessary.
Ok re-read his posts… thought he tried three times , the third using the poster board. I thought the set of pix he was using soric as a core. The poster board is the reason for this failure. It’s all Hanaldo’s fault!
Here is what i used as far as the perforated film. I jist now re read the description amd understand more what it’s for.

Here is how it turned out

As you can see the resin didnt go far or do much. This is with the mesh on the feed side overlapping onto the core material i was calling soric. Turns out I’m not using soric but another core material
Here is the core material im using that i thought was soric

I still have more of this and would like to know if its the correct stuff for infusion and could i use this in my small footplate project that i used poster board foam in.
This is the release film i had and not sure if i should be using this stuff or what?

Description of release fabric:
Super high quality Silicone coated Release Fabric. Used to allow resins to flow away from composites to breather Fabric -used in Vacuum Bagging.
I only had small scraps of the release fabric. Not enough to use on the wheel chair back piece. Thats where i used the perforated release film. I see now perforated film may not the stuff to use.
For now and until i can learn how to do infusion, I’m going to stick with trying to make a smaller part. A small rectangular foot plate. The piece i used poster board foam in. Which did not wet out nearly at all.
I need to figure out the correct supplies and lay up for a small flat rectangular piece with a core.
Ah jeez. Yeh these are all the wrong materials for infusion. Your perforated release film is the blue type, which doesn’t have enough holes to infuse successfully. If you want to use perforated film, you need either the pink stuff with lots of holes, or the clear ‘bread wrap’ stuff with even more holes. Ideally for now though, just ditch it and use peel ply. You’ll hate trying to peel it off, but it’s less to go wrong until you get the hang of it.
Then, that core that you were using is Coremat. It isn’t suitable for any vacuum assisted moulding, let alone infusion, as it collapses under vacuum. So you can’t use that at all either.
The peel ply is acceptable from Soller, as long as you don’t need to do any secondary bonding. If you’re going to pull it out of the mould and use it as is then that’s fine, but if you need to glue something onto the back of it then you need to be aware that the silicone stuff will leave traces of silicone that will contaminate your bonding surface. Otherwise, it’s fine.
So, the core will be a large reason for your failures. It may have worked with the perf film you’ve got, but with that core in there it never stood a chance. You need to get yourself some Soric, and that will solve a lot of the issues.
Lastly, have a play around with the configuration of your infusion stack. The method that cheekybrad is suggesting with mesh and spiral on the vacuum side will work and it will work well. This is the technique that EC demonstrate in their videos, so you can watch and watch and watch them to understand.
That said, it isn’t a technique I necessarily agree with. Interestingly, if you attend one of EC’s training courses, you will learn how to setup a brake zone for infusion, so they also use both techniques. A dry laminate stack will evacuate air perfectly fine without mesh under the vacuum port. I infuse laminates every day with a brake zone, and it works perfectly.
So again, I suggest playing around. Try both methods and see which one you find better/easier for you. We can tell you what to do all day, but you’re only ever going to learn by doing it yourself. You NEED the right materials though, really do your research before you buy things. Check out the EC website, even if you don’t buy from them they provide you with pictures and descriptions to make sure you are getting the right stuff.
Ouch! Coremat…
No prob!
Mesh the whole mold surface
Peel ply whole surface
Place laminate
Coremat
Laminate
Peel ply whole surface
Mesh whole surface
Put resin and vac lines in any configuration you want
Bag
Infuse
Coremat also works with infusion, not nice but it works.
Read the MTI Thread, there are really all questions answered! I do not want to write that again and again.
But just a few things
Your system has to be tight (100% not 99)
Resin degassed
Brake zone
And MTI makes life easier
If you follow the instructions in the MTI thread you will not fail!
