On a 6 m long and 1m width mold I have a central resin feed line. How many resin inlets would you use and what spacing between them?
Thanks
1 inlet if you have a central feed line over the 6m distance. Than the resin only has to travel the 0.5m to each side. That works.
Ok that means that travelling 3 meters to each side thru the spiral tube is no problem.
Thanks
The 1 feed line should be sufficient but may be a little slow. Just make sure your gel time is long enough to allow the entire part to fill. You can add a second resin inlet which will speed things up and also serves as a backup in case one of the inlets becomes blocked of course the downside is that you will waste a bit more resin and use more tubing.
DD is right, but missed out on the question: Indeed there will be 1 feed (in the middle), but how many resin ports should feed that single feed line?
The size of the inlet partly determines infusion speed. Depending on diameter of the hose I would choose 2 inlets over the length of 6 meters, one on some 1/4 and one on 3/4 of the length. When using small diameter hose (less than 8mm) perhaps use 3. For the perimeter use MTI hose and a single vacuum outlet, or make sure you have 6 outlets: on each corner, and 2 in the middle. Rig them with valves, so you can shut them off once resin fills the hose. (and when not using the MTI hose, use a brake zone)
I would choose a spieal hose with 13mm diameter and a 12mm feedline. Than one feedpoint will be enough. That are only 6m, not 60. On 60m I use 4 feedpoints and a 20mm feedline.
Use a resin with more than 120m pot life, I would choose 300min pot life for the first try. And MTI hose works great.
I know its quiet old but still a present problem, so you guys telling that using 10mm feed is okay but it will increase the speed and then it may cause resin voids in laminate because of too quick resin flow… correct me if Im wrong
On a 6 meter mould, with 12 meter resin front, 10mm is OK, and will be quite slow.
