I don't how much you hear this....but that is a beautiful process you designed. Take that from a guy who owned a business for twenty years that made composite aircraft propellers....GREAT STUFF!!!
Thank you. I have been looking for a video on this. I can fill in the blanks because I have experience with vacuum infusion, but I'm sure you could expand this to a course level teaching series. Than you for educating.
@shkssj88 yes! Using polyester resin can not use a vacuum greater than - 0.65 bar because there is the formation of microbubbles caused by separation of the styrene resin.
I used to do that - making fibreglass yacht decks. I thought fibreglass was a miracle material and couldn't understand why we didn't use it for everything.
Havent gotten that far yet - after 20 yrs as a homebuilder Im in school for a naval architecture engineering degree. This vacuum infusion process I think is the future of the industry for pleasure/sportfishing vessels which is the niche I want to pursue. University of Michigan offers a bachelors in engineering in this. In my 1st yr. Great video.
@beachnative420 Proval problem of sealing film on the side of the mold. this fence has to be perfect to avoid the occurrence of air bubbles. The vacuum must also be controlled to a maximum of -0.65 bar. Above this level there is the removal of styrene resin.
Do you know what, I am almost sure I have one of those hulls. Looking at the size, the design and the ribs in the hull I have one of those.. It sits very high in the water but I have to say I am very happy with it.. Only issue is the size and storing it.. where can I get another hull please? I got mine from the local council tip as a wrecked boat and I put it all back togeather into the smart boat it is today..
Beautiful product, Thanks for posting the video. Is there ever a problem wetting the entire hull area or does that fact that the viscosity of the resin wetted cloth is higher than the still dry areas guaranty full wetting? Very cool to watch.
Olá Edmar, os moldes são fabricados também com resina e reforço de fibra de vidro pelo processo manual. Você tem que primeiro ter ou fabricar um modelo da peça e depois fabricar o molde deste modelo. Para quem nunca trabalhou com estes materiais é mais difícil fazer os moldes.
have some questions 1- how big is that boat in inches? 2- do you do custom builds? 3- can you make that boat 45" L x 10"W X 7" D? 4- how much would it cost in u.s.d. u.s dollars to build me one
Olá José, este foi feito com poliéster mas pode ser feita também com epóxi, basta ter o equipamento adequado. Agradeço seu contato e gentil comentário. Obrigado
Hey, perhaps you don't know yet but there's this new thing just out called movies, the images move just like in real life, and you can hear people talk too,they are called talkies.
Only one layer of 1.5 oz mat. It would take a lot more work on the top mold if you did a real boat,20'- 40'. You would have to compensate for the thickness of the material, from the top of the freeboard to the keel of the boat. I think that is were infusion beats RTM all day long. TRM is nice and all, but the cost to do the inner mold with complexity would be to expensive.
BubaJ1000 The throw away plastic, peelply, infusion mesh, bleeder cloth and vacuum tape keep adding up, there is a turning point based on production volume where this becomes cheaper.

Congratulations to Paulo Camatta and Luis Boloni for the excelent job.
you always can count on CROMITEC Whenever you need.
Can someone explain me why there's no need for an infusionmesh?
What was in the small white pot used in the mold before everything else. wax? but what kind .
thats got to be the best cast ive ever seen nice work
Thank you. I have been looking for a video on this. I can fill in the blanks because I have experience with vacuum infusion, but I'm sure you could expand this to a course level teaching series. Than you for educating.
Well done!! Maestro!
greetings from Greece
Belo e maravilhoso trabalho...
@deepak762 your resin hopper is pressurized at one end as well as
vacuum assisted at the other.
it's a push pull effect
Best work I have ever seen well done guys
@shkssj88 yes! Using polyester resin can not use a vacuum greater than - 0.65 bar because there is the formation of microbubbles caused by separation of the styrene resin.
Thank you for sharing that excellent information.
Great, are you guys making big level for racing jet boat
I used to do that - making fibreglass yacht decks. I thought fibreglass was a miracle material and couldn't understand why we didn't use it for everything.
Brilliant. How did you establish location of vacuum to draw all of the epoxy throughout entire piece? Trial & error?
Thanks Jim! Fluid theory and calculation or trial and error with process knowledge.

@@jimmascaro2456 Follow your dreams Jim and
Success always!!!
Paylaşım için teşekkürler, çok güzel olmuş. İşçilik harika
👍 👍 👍
çok teşekkür ederim arkadaşım
Thanks for showing how it's made . I picked up a longer hull wonder where to get rest of stuff to complete.
Thank You Dear Teacher!
Thanks
@robotmotor Use soft bristle brush and apply a second coat after the first polymerization.
Greetings from Brazil!
what name of this process
hello, where can I buy this fiberglass vacuum injection technology, and the mold made according to my requirements?
what is that red thin plastic sheet for ?
@JustWonderingHowToDo The inner part is used a silicone ring seal type and is used outside a conventional rubber type wing.
@beachnative420 Proval problem of sealing film on the side of the mold. this fence has to be perfect to avoid the occurrence of air bubbles. The vacuum must also be controlled to a maximum of -0.65 bar. Above this level there is the removal of styrene resin.
Excellent demonstration.
Thansk for sharing.
Waht material did you use to machining and make the mold? It is a foam or something similar?
Plywood structure, plastic mass and high density foam.
@@baxo70 thank you
@@morraderi glad I could help.
Very good! Let us an eye-opener!

M Collins hi mate were did you get it from because I wanto buy one? by anay chance is it a replica of a blackwatch charter boat cheers?
@leparditas Not plastic, but a superior cast composites
Awesome work
Ya the Japanese vacuum mold them outta plastic the difference is so negligible.. you guys are really plying your craft thanks for sharing
What's the name of white color things?
fiberglass mat.
Excelente trabajo.¿hacen lanchas grandes?
Como fazer o molde
lindo vídeo
Beautiful product, Thanks for posting the video. Is there ever a problem wetting the entire hull area or does that fact that the viscosity of the resin wetted cloth is higher than the still dry areas guaranty full wetting? Very cool to watch.
John Sikes Must use resin and specific strength for this process. Regards
Y do one mould when you can do 5 at a time
what is difference between Light RTM and VARTM process?
@linearstar No problem handling fiberglass blanket. You must wear gloves and mask and goggles when handling resins.
What is the name of the material you guys use for the top cover, the transparent mold. The one you use when applying the last layer.
Super Schiff, sehr professionell !!
Nice. Very clean.
why not make video?
Exothermic reaction control? Oh you mean a thermometer? The exothem can not be controlled once catalyzation has begun.
Perfect, meant to accompany the exotermic reaction that occurs inside the mold. Thanks.
I mean you could still cool it down when reaction starts to become hefty. But you would have to be quick.
Lol... I thought the same thing
Para confeccionar um molde, é utilizada a resina líquida ou em tudo? Vocês podem me ajudar?
Grato
Olá Edmar, os moldes são fabricados também com resina e reforço de fibra de vidro pelo processo manual. Você tem que primeiro ter ou fabricar um modelo da peça e depois fabricar o molde deste modelo. Para quem nunca trabalhou com estes materiais é mais difícil fazer os moldes.
well made presentation. waiting for others :) greeting from Poland
why not divided to compartments?
one little hole can sink all that
Is a layer of wax calibrated.
Greeting from Brazil.
where i could buy a boat like this ..???
Graupner or any other well assorted RC model store.
English instruction would be helpful
@beachnative420 Exothermic reaction control? The correct temperature to remove the piece from the mold!
exothermic reaction is for cure of resin. wait for two or three hours after part has cooled. 30+ yrs in contact mold glassing.
if i want to create mold for wings,is it need to use upper and lower mold for both side?
عايز حاجه اعمل بيها البانيو مشروخ
@shkssj88 Ok, and one question? when using epoxy resin the gelcoat is also epoxy?
Quoting Wikipedia; "The most common gelcoats are thermosetting polymers based on epoxy or unsaturated polyester resin chemistry. "
The best for airplane is infusion resin or vacuum bagging

it is here ? what is this stuff please.
Très très bien cette façon de faire, pas de gaspillage de la résine et un produit fini propre, donc moins de main d’oeuvre.
Espectacular muy bueno 😃👍👍.
Gracias Jorge Nelson. Abrazos
白色的漆是甚麼材質的漆?不會掉漆嗎?
Gelcoat (3mm)...
VALTER FERREIRA Gelcoat 是一般的油漆嗎?
那是殼膠
請問您說的殼膠是加了顏料的環氧樹脂或不飽和聚酯樹脂嗎?外殼用那一種樹脂比較好呢?
Thank you for sharing 👍
What was the original plug made from?
A nice video. Do you use Epoxy base Gel coat and Epoxy resine here or Polyester..?
Thank for your comment :) greeting from Brazil
Buenos Trabajooos😅😉🤗
Agradeço o comentário, abraços
what is the transparent top mold made from,
is it elastic ?
can you please recomand any literature
great work,
greetings from Croatia
Perfect guys!
Great! Where can I bye this type of hull?😀
Thank you!
This hull is manufactured only in the ALMACO composite courses.
Great video, thanks.
Skill and Passion.

Does it work with carbon fiber?
Ensine passo a passo
I make model boat so much different to this one, using marine plywood and fibreglass resin. I make cruisers and speedboats.
music track not required
Excelente 🇩🇴🇩🇴🇩🇴🌎
Muito obrigado Alberto!!!
Nice looking boat
Gracias, por compartir este video.
have some questions
1- how big is that boat in inches?
2- do you do custom builds?
3- can you make that boat 45" L x 10"W X 7" D?
4- how much would it cost in u.s.d. u.s dollars to build me one
DaveStarr4 I do not to sell but to teach
I want one of those hulls for FPV boating!
What is the red lower-mold made of?
Tooling gel and fiberglass. Most tooling gel is orange or red.
I use polyester but can manufacture epoxy
regards
Parabéns!!!!
Resina poliéster ou epóxi???
Obrigado.
Olá José, este foi feito com poliéster mas pode ser feita também com epóxi, basta ter o equipamento adequado.

Hey, perhaps you don't know yet but there's this new thing just out called movies, the images move just like in real life, and you can hear people talk too,they are called talkies.
Yes works with a thickness exceeding 2 mm.
Depending on resin type you can go up to 1/2 in laminate.
Only one layer of 1.5 oz mat. It would take a lot more work on the top mold if you did a real boat,20'- 40'. You would have to compensate for the thickness of the material, from the top of the freeboard to the keel of the boat. I think that is were infusion beats RTM all day long.

where can I buy that boat hull?
Me interesa
Thank for your comment
Impresionante.....
@madamepo Sorry, but this boat and I developed this scale 1 / 20 and is exclusive of the courses that I do.
Greetings from Brazil
Obrigado, abraços
Hyyy am from Timor Leste how i cant get machine like that??
i need to make fishing boat in our country to sale.
Super explained tks
Make one with plastic heating
where can i buy that old to make my own fiberboat?
Good lavoro
Grazie Elvis!!! Abbracci dal Brasile!
are good....?

I'm so glad that they were given gloves and respirators and eyewear. Glad I dont work there.
Guy Tero me too want to work there
@shkssj88 Hi, perhaps the problem is to use a vacuum up to -0.65 bar
Greetings from Brazil!
