The vacuum system check you preformed is called a Rate-of-Raise (ROR) test. You should set a standard time lapse and max pressure / vacuum raise for your process control and make sure everyone follows the requirements. Thanks for the video, it was great.
Wish this was up back when I was learning....one of the only videos on resin infusion that are remotely helpful...the others do unimaginable NO,NOs!!!!
I'm no expert but rtm light only gets you a 20% fiber content and infusion gets you a 65% fiber content making it much much stronger. Not to mention the added cost of all that extra resin it might not be as bad as you think.
8:05 ... this can be simply avoided if u just put the kit on the bag and not on the mold... dont know why most of u are doing this since most of you dont even use it right if u want to use this tehnique ... use only 1 strand and not loop it like this guy did in the video... you save material (money) with this and thats the only purpose of putin the kit on the mold
So you know better than everyone on RU-vid that does this that way, because? This is the way even 3M Composites and several other companies show how to do it, and then get paid to do that. So you're saying they're all doing it wrong? You think you're better than them why?
I use a different infusion technique on my moulds, thats because they are smaller, but I still put the bag on exactly the same, its the best way by far, I've tried them all!
@@josephd.4890 i have been doing this for 20 years... and the only reason why this is done in the video is to save money ... but in most cases you dont save anything ... u just do it slower its way simpler to pre apply the kit on the bag rather than later and you evade issues that you clearly dont know of
@@RePlayBoy101 you mean the sealant tape ? In the end it all down to the way you feel the most confortable with. In the aerospace everyone uses this technique. It takes a big table to apply the sealant on the bag, and then when handling the bag you will pinch the sealant. Sealant on the mold wins the race when you've got the right technique.
@@SuperYellowsubmarin you cant pinch a piece of gum... its mouldable ... and this is the slowers out of the options ... this methods were used 20 years ago and things evolve through the years especially if you like to experiment like i did
@@vdubberc I find it funny that people who aren't in the know or telling other people that this is the wrong way, considering that every company that does this professionally shows them doing it this exact same way! Just because you do it a different way to save money doesn't mean you are doing it the right way
@@josephd.4890 Ok, well I never said this was an incorrect procedure, so I'm not sure where you got that. I think perhaps you're misunderstanding what I'm saying, or simply misread my comment? My reply was specifically directed at nedgeee80's comment to Vilo Shmillo about finding a "better way" which uses "less waste", which does in fact exist. That method, however, does NOT work for everything or in every situation, but it does exist. That is all my comment is about. There is now a method/product you are able to use, which results in less plastic waste. It is also by no means cheaper than a traditional bagging method like this, specially when you consider huge businesses buying bagging supplies in such huge quantities. It is also not any more or less correct (depending on the end use of the part), it just uses less consumables at the expense of more time spent upfront. For one-off parts, or parts that must follow very strict procedures (aerospace, etc.), this is the only viable solution. I'm not, nor would I ever, argue that. For a small company that makes only a few different items (specialty automotive company perhaps), small to medium in size parts, and probably not structural, you can now (again, not that new) create formed, silicone, reusable "bags" with built in air passages and hose connections. which would rid one waste component from the layup. I'm not arguing this method even the slightest bit. I have used it in the past and will use it again, since making moulded silicone bags for my one -off personal parts would be way too costly and highly unnecessary. If, however, I were to produce a couple of my items for sale, I would consider making a perfectly moulded silicone "bag" for the time and mess savings alone.
