This is the perfect application for the MTI hose. Just lay some around the perimeter and have a single resin inlet in the center, there is no need for resin spiral, just a silicone connector. Control infusion speed for superior wet out. resin feed cup placed 1 meter below the mould to get excellent resin-fiber ratios.

I always prefer to infuse from the center and draw a vacuum around...that way you have a strong/even vacuum all around your part.

I am pre-planning my infusion project and I am on the fence as to how to lay out my spiral tube for both the resin and vacuum lines. There is a lot going on with this mold so I want to be sure that the part wets out properly. I have made a few diagrams to share my thoughts and see if anyone else has an opinion.

Green Line = Resin Spiral
Blue Line = Vacuum Spiral
Red Dot / Green Line = Resin Feed
Red Dot / Blue Line = Vacuum Feed

Plan A: Pull from one side to the other

Plan B: Pull vacuum from the center line of the part and run the resin along the perimeter

Does anyone have a take on which would work best or is there a better way about it?
