Making A Fibreglass Mould

This is a Video demonstration showing how to make a fibreglass mould, using an existing master mould we had

[@luvstruck2733]

Enjoyed the video. Being unfamiliar with the measurements, and the products, I enjoyed the music, and the narration.

[@slimthug6675]

Simple and clear.... great stuff guys, thanks.

[@ellington4701]

Very well structured, informative video... Instantly added to favorites and will be referenced several times for my upcoming first fiberglass project. Thanks for posting.

[@mr.perfect1067]

Me too

[@VinothKumar-qo7ry]

Thanks for sharing knowledge sir. Huge respect for your tremendous effort.

[@Automedon2]

Skilled craftsmen are a national treasure. Once we lose the manufacturing we lose centuries of knowledge to the point where we will never recover it. Terrific video

[@NickVenture1]

I just now have to do this. And remembered your great video. Had a look. To make sure I will apply the gelcoat well. 2% of catalyst.. and 6mm thick.. (not more). Got it!!! Thanks a lot.

[@ecfibreglassuk]

Glad it was helpful!

[@RishiSingh-uy8qx]

I think it is 0.6mm and not 6 mm thick, the first coat(black one)

[@charliegrpdixon5944]

very helpful video for my A level homework. thank you

[@ecfibreglassuk]

@GasserGlass Hi thank you for your reply, The methods we use in some of our videos are quite basic, the company producing these moulds do have more advanced methods but we try to keep the demonstrations to basic hand lay up without the need for spray or sometimes trimming equiptment. some of our customers buying our materials are first time user who may not have access to spray guns and pnumatic tools etc, hopefully we will get the time to demontrate other methods in future videos, Kind rgds

[@motomx69]

What a great video! and quality mould!. i dont think ill need to make my mould as strong, but if you will be using it alot, this is a great way of making it! thanks very much for youre video

[@percival23]

There is an old saying "God is in the details" Clearly the makers of this video understood the importance of the details in this considerable process. Well done lad's.

[@waleskayazzie994]

You mean devil is into detail😁

[@147andreluiz]

Question please: how strong is fibreglass? I was thinking in making a car roof cargo box out of fibreglass but obviously, has got to be very strong. How strong one layer of fibreglass is? How many layers would I need? Thanks

[@bizling]

When waxing the mould, is it ok to leave it over night say if you've only achieved 6-7 layers? Same applies to the former?

[@soldierofjudgement0477]

Is there any chance you have the intro clip by itself? Just wondering.

[@richarddale76]

@ecfibreglassuk Thanks for the info. Its just i've seen other on here use upto 6! layers of wax, then 2 coats of PVA release agent. This was for an epoxy resin on carbon 6k fibers though. Would you recoment either/or rarther than both? P.s When you back open after xmas? got an order ready to ring through. Thanks again

[@reynoldpasilan494]

hi , do we can use other kind of material to put a color instead of gelcoat, is it possible to use an enamel paint ?

[@ecfibreglassuk]

Hi, its really best to fully assure the coating is at adequate thickness throughout, you can locally re-apply to the effected area, hope this helps.

[@smoothon]

Great video - thanks!

[@ecfibreglassuk]

Thank you :-)

[@THOMASTHESAILOR]

I think the most stressful part of Mould Making is the music, it'll drive ya crazy before your done..

[@filipwyberg]

Then youre not focused enough :D

[@craigjones9244]

Haaa true🤣

[@hfranke07]

Me too.... music is sick

[@corneilcorneil]

I agree, the music is disturbing.

[@jaywinters2483]

Almost had to exit out👎 music ruined it

[@mindfreak001009]

does the gel coat can be sprayed? using a compressor? thanks..

[@ecfibreglassuk]

Hi The Gelcoat is the durable, cosmetic and more often pigmented finish you would see on the part you are producing, it provides weathering and water resistant properties on the part surface, you could pore silicone in just as always try a small test piece first, hope this helps

[@ecfibreglassuk]

@irfanfikri This is known as The Plug / Mastermould: To produce a mould you need a pattern or former commonly called a “plug” an exact replica of the finished item. Usually you will have to make the plug from scratch. The plug can be made from almost any material as long as it is made rigid, accurate, dimensionally stable and set on a solid foundation. this particular one is made of fibreglass which we made earlier from another plug made from wood which was primed as smoothed to a gloss finish

[@Gnetluvsgreg]

What is the purpose of the gel coat? Can you cast silicone in a mold like that?

[@profesorkai]

how much did this size mould cost to make all together?

[@adelkl5711]

sometimes a certain kind of yellowish powder is added to the resin could you tell us what it is?

[@mclk40]

Qual o nome da tinta que vc usou antes do revestimento da fibra?

[@artamd]

Hi I have a few questions. Before painting gelcoat . How many wax to original part ? Thanksyou very much

[@manishagopalka6896]

When you apply the first layer on consolidation material i.e, the mat with the fibres, you are sticking it in with epoxy resin I presume? Or is it some other material?

[@ecfibreglassuk]

Hi, it's polyester resin

[@MikeTheDidgeman]

fiberglas is so cool , iam making didgeridoos of it! :) I wanted to ask for the roller: can I use every kind or should it be a specific material? thx

[@elleburgess3498]

Great Video

[@cherfieldm]

Thanks, can I apply varnish on the finish fiber glass project instead of paint?

[@ecfibreglassuk]

+cherfieldm Hi, please give us a call on 0191 497 5134 to discuss

[@11Gunn]

I have removed part of my Dashboard that is made from 'Pleather' material puled over metal, there is foam/sponge in between to give it shape. I'm looking to made a solid fibreglass part and not have the spongyness. Can you tell me if its possible to make a mould from the plastic/leather style dashboard material? Thanks :)

[@saicharan6339]

Can I know this place .. iam from Hyderabad We have a electrical work shop and we are thinking introduce sales also from coming season ..so that we need what was the exact process to make cooler body dies

[@cimrman2]

Its amazing a super nice coooool project

[@ecfibreglassuk]

Hi, Optimold relies on high exotherm for best results, bit of a nuisance sometimes depending on what your making, some other tooling systems recomend less Resin, thanks for the positive comment.

[@CAL1MBO]

Thanks for the video

[@HumanBeingSpawn]

Can this method be used to create a durable kitchen sink?

[@katinekaba1354]

Thank you. I am interested

[@IcarusX72]

Great stuff!! What is the mixture you used for the reinforcement board?

[@ecfibreglassuk]

Hi, what do you mean?

[@jonathanflud492]

I have two questions about the video what wax do you use to keep the fiberglass from sticking and what is the black stuff u put on first to give it that gloss look after it is done?

[@ecfibreglassuk]

It's all explained in the video as he goes

[@Kleano52]

Where can I get this stuff?

[@jananimanikandan8483]

how to make that mould...and whats the degree of heat for melting and how it looks.. This video is very informative.nice

[@Jules262]

@EastCoastFibreglass - Thank you for this amazing video!! Is there a translucent version of the fibreglass that you could recommend that would allow light to shine through?

[@ecfibreglassuk]

Not for mould making. We do some clear epoxy casting resins which may work if cast into shape, or we sell perspex sheets

[@Jules262]

@@ecfibreglassuk Oh, that's great! What's the name of your clear epoxy casting resins? I am interested!

[@ecfibreglassuk]

@@Jules262 you can find them here www.ecfibreglasssupplies.co.uk/category/clear-epoxy-resins

[@maxwellbolzman7077]

so now you can put your fiberglass on?

[@noonedude101]

Would this work for something the size of a car?

[@Dole111]

polyester resin or epoxy resin?

[@lucasoncin3100]

Very great... But.. How do you trim what's over the mould? Thank you..

[@ecfibreglassuk]

Hi, same way you trim it to fit. The edges can be sanded down to get rid of the rough bits too

[@cherfieldm]

What type of fiber glass cloth materials do I need to use in high temperature area like engine bay?

[@Syndicatet3k]

this is really about the resin system , you should go with polyester resin, fiberglass for cost, or go Epoxy/carbon and cure the part at the service temp desired

[@janpakx]

Hello I have so important question can I used fiberglass mould for to make Carbon fiber parts? please respond me very soon,Thank you so much

[@cyccompositeschina712]

peter John I guess it is depended on the mold applications

[@ecfibreglassuk]

@richarddale76 The treatment of moulds is slightly different for epoxy moulding, some people will only use the PVA alone for epoxy mouldings. Unlike polyester which relies on a chemical bond, the epoxy relies on mechanical bonding so will sometimes still grip to any microscopic scratches on the mould surface even if waxed, PVA produces a good solid barrier between the Epoxy and Mould surface. We are open again on the 3rd of jan. Thanks again and All the best for 2011 Kind rgds ecfibreglassuk

[@LowCostCncRetrofits]

Painting tooling gelcoat is still the quickest no fuss way for small moulds nice video

[@DJW147]

Hi - my A Level class and I have enjoyed watching this video, it has been very good for explaining the process for their A Level studies. They would like to know what the end result actually was, can you help? They have some very wacky ideas!!!!!!Mr Wakefield

[@ecfibreglassuk]

Hi Mr Wakefield - These are moulds for life raft containers, some of which can be seen in the movie Interstellar - It's our claim to fame :-)

[@ecfibreglassuk]

Hi , material at 4.30 is basically a filler paste with low shrinkage properties, and the other is Opyimold Tolling Resin, hope this helps.

[@skeeterbuggy]

you can get gelcoat pre colored in any color, or purchase tinting material to color as you need to.

[@montetown5741]

When you don't use the PVA, what is the trick? Is it that the surface has to be perfect gloss without ANY porosity seen in the surface anywhere? I have some areas still which I could sand out some micro-craters.

[@fariborzhashemi3052]

hi, thank u for your video. I would like to know if this the mould, then what is the red colour?

[@ecfibreglassuk]

Hi, the red is the gelcoat from the part they're making a mould from

[@ecfibreglassuk]

Hi, yes its a fibreglass plug that was made, in this case the male part outlasts the female part, so after every few thousand lifts this is brought back in to reproduce another, when its put back into stores a Gelcoat few layers of Glass is usally applied for protection, you can get mould protect, but its sometimes as easy the 'old fashioned' way :-). best rgds

[@Flawless_fashion_1111]

Sir i m Intrast to fiberglass work experience to 15 years plz reply me

[@nixland]

Can you enlighten me about polyester resin high shrinkage level? I want to make mother mold for a helmet with polyester resin as normally people do (main mold using silicon). Should I concern about the shrinkage problems?

[@ecfibreglassuk]

Hello, I couldn't give specific shrinkage rates as it's entirely dependant on heat/thickness while curing. Trial and error is the best way to go

[@julietgaskill374]

I just wanna find out, is tooling Gelcoat the same as regular unwaxed Gelcoat. Or is tooling Gelcoat something different

[@ecfibreglassuk]

Tooling gel has a vinylester base so it's more suitable for mould making

[@hengineer1]

Really inspiring video - you make it look way easier than it is. I found your video looking to troubleshoot a Modified Car Rear Spoiler that I'm working on - hybrid 3d printing and glass fibre layup. I'll be making moulds next! Thank you for sharing and feel free to check out what I'm up to and leave a comment.... I've subscribed!

[@ecfibreglassuk]

Thanks, I've taken a look at your video on creating the spoiler and also subscribed. feel free to visit our website for our contact details, drop us an email or call and we'll be happy to help with advice once your ready. Kind regards Martin

[@Noorstud]

Very nice job. Thanks

[@smallnuts2]

I was wondering, at 4:52 the wood you left in the square corners? Does that have to stay in there? Would it affect strengh integrity?

[@ecfibreglassuk]

Hi, the timbers around the outer edge are left in place, this creates a solid core which reduces flex on what would become the outer flange of the mould. This is because the flange area can, at times, be under stress when levering parts from the mould.

[@LovemeAquarius]

What is the mixing ratio of TALC and RESIN ??

[@bigtasty6040]

Love the music

[@nathanblagdon3412]

how much would a piece like that cost in materials?

[@arneolavnordgulen3026]

If I am to make a boat mould, can I make a plywood mould and then coat it with a couple layers of fiberglass and a layer of gelcoat? So that I could mould the hull straight out of this? It is a one off production, and would not need a master mould.

[@ecfibreglassuk]

Hi, that would work, just make sure you've got a good smooth finish on the plywood, and sand down the fibreglass before you gelcoat for the best possible finish on the part. And plenty of release agent

[@serchmarc]

what if ,dont sell the gel coat in my country what im gonna do? to make a professional mold?

[@ecfibreglassuk]

@LovemeAquarius Hi, after the resin is catalyzed add talc until you can just pour, approx a 2:1 resin talc does this job, best rgds

[@KenPapara]

Hey have you tried using Hemp fibre matting before?

[@HIERDNUIZ]

Yes, very weak.

[@SomeBubba]

How do you make that orange thing? That is what I want to know how to make. I understand prepping the mold I need to know how to get to that point where you have something covered in that orange stuff

[@ecfibreglassuk]

Hi, your original mould can be made from a huge variety of things - plywood, pu foam, silicone, latex etc. You'd create a mould of the shape you need in reverse, coat that in release, and use fibreglass to give you your master mould, essentially. This is the orange thing you see here.

[@SomeBubba]

EastCoastFibreglass thank you. I've been looking all over everybody shows the mold and waxing it and I couldn't understand how to create a mold to begin with

[@dedearifin6115]

what is the distance of each layer, and how many layers of gelcoat, resin, fiber and the last material ....?

[@dedearifin6115]

UP

[@dedearifin6115]

[@serchmarc]

thnk you for your time to answer ,yes that helped

[@ahalgamal]

hello .... thanks 4 the vid i want to ask about the name of material you poured at 4:30 and material that coat it at 5:00 plz .... write its name

[@AestheticButterfliez]

its very good video for fiberglass workers its so nice cos i have my owen fiberglass besnuss thanks

[@Niceburg400]

Hi. Great video. I am an ex fiberglasser who only used gel coat in the past, sanded and sprayed it afterwards. Why is there so much nonsense now about gel coat never curing, or you need topcoat or flocoat instead. Has it all changed so much.

[@arunnaik2224]

Fine finish,,,,great.

[@rasheedp4140]

What kind of materials using before jell coat?

[@ecfibreglassuk]

+Rasheed P Hi there, Release agents are applied before the gelcoat. For this mould we applied mould release wax TR104 hi temp. However your choice of release agent will also depend on what resins you are using and what material your mould or plug is made from.

[@ecfibreglassuk]

Hi, there is nothing to substitute the Gelcoat im afraid! Car wax is a release ageant, you need the Gelcoat for the mould surface.hope this helps

[@Assimilator702]

If you're NOT making production pieces....which need to be as close to PERFECT as possible.... you CAN skip the gel coat step. But this will give you a part thats not smooth as glass so you might have to do some finishing afterwards. Also keep in mind if the part you're molding has a deep well like the one in this video....you might have a difficult time removing it from the mold. Gel coat is very important when making repeatable molds and will reduce finishing time.

[@lilgiovanni5528]

Why you clean the wax ?

[@aliabkhezr6797]

hi dear friend can you help me to make this marbles? what is furmula(raw materials)?how raw materials mixed??? wait your response thanks

[@yassinchbani4267]

ali abkhezr maybe this mold doesn't use for artificial marble but it's useful to make mold for artificial marble.

[@costaaddict]

If I understand this correctly: Original part -> wax -> gel coat -> fiberglass + resin (repeat). This would give me a mould of the original part?

[@ecfibreglassuk]

That's basically it

[@Pushyhog]

Talcum mixed with resin/hardner? It that blk epoxy tooling gel or polyester tooling gel?? I see you using TR wax! Do u ever use frekote??

[@ecfibreglassuk]

Hi, talc can be used to thicken up the resin to reduce drainage etc. We used 65pa gelcoat for this, which is polyester based. Not had much experience with Frekote, we tend to use carnuba wax and PVA, or more in depth systems like Marbocote

[@aribv]

You need a mould to make the mould...I'm after the initial mould, How do I make that? Anyway, great video!

[@ecfibreglassuk]

That is a master mould taken from the initial mould that was made, this can be used time and time again to produce a new mould.

[@michaelg4931]

***** Take the original part and make sure the surface is a perfect as you want the copies to be. After that you would do exactly the same steps in the video. Ie, clean, thoroughly wax, apply PVA (an alcohol release agent), tooling gel coat, and finally the fiberglass and other reinforcements. You want your newly created master mold to be as flawless and robust as possible.

[@DodongWerkzPh]

start with a plug. hehehe

[@1985cactus]

You need a pre-inital mould to make the initial mould

[@malmalhi007]

i used cement to make a mould for a sink .. . many moons ago

[@tiredfingers99]

What is it called? Isothalic resin? What is the Gelcoat called? How do you know that when you add the 6 layers? I mean when I wax the layers blend.

[@EastCoastFibreglass]

Hi, 14pa Gelcoat and 491pa Polyester Resin hope this helps.

[@ecfibreglassuk]

Hi, we used 10 waxes for taking mould from plug and also taking part from mould, best rgds

[@user-jk3sg9jq3o]

great video . Please tell me where the places of sell molds such as the red mold which was at the beginning of the video and thank you very much ... The template I mean is like who in the next link

[@Newbenwindowcleaningcom]

hi there , i made mould , turn out the gel coat going terrible making not smooth surface , can i regel coat it or bondo to make it smooth ?

[@ecfibreglassuk]

Hi, you can lightly abrade the surface and reapply gel, or polish it back to get a better finish

[@irfanfikri]

but how do we make the "red thing" first?

[@siddiquesorganicfarm]

Ok Good friend. And how u remove this from mold? After cleaning the mold what you applied for easy removing? Please reply

[@ecfibreglassuk]

Your mould should have adequate release for the part to come out without resistance

Hi, this would be the Gelcoat used in the process, best rgds

[@menajakoub7727]

can i make wood mould for fiber to make cover for machine??????

[@michaelg4931]

Mena Jakoub You could make the mold from wood (or foam), then cover it with a thin layer of fiberglass (do not use polyester resin on foam as it dissolves many types of foam) to strengthen and consolidate the mold then coat it with tooling gel coat.

[@dedearifin6115]

What the name for the black liquid or the first layer..?

[@dedearifin6115]

Roger Rarebit What is the other name of tooling gel ...?,my search in google does not exist

[@ecfibreglassuk]

It's polyester gelcoat

[@dedearifin6115]

EastCoastFibreglass Owh ok thanks a lot for this information 😀👍👍👍

[@dedearifin6115]

what is the distance of each layer,and how many layers of gelcoat,resin,fiber and the last material...?

[@dedearifin6115]

UUUP

[@nemo6686]

Thanks for the video; as a complete novice it was informative, but the use of the terms 'mould' and 'plug' seems confused. Even in the description above - is it a "master mould" or a plug?

[@ecfibreglassuk]

Hi, the master mould is the plug

[@deadeye9703]

Great video - I'm going to send people to this from now on rather than explaining the process. I noticed that you don't mention the need for release angles in the plug ? Additionally, a boss for an air fitting laid up in some part of the mold helps pop the part with an air compressor. If one is making enough copies to make a mold worthwhile, it definitely cuts the turnaround time and (especially on bigger parts) one person can pop the part.

[@ecfibreglassuk]

Hi no it was not mentioned in this case a draft angle of 2mm was used on the sides of the part , thanks

[@karibulislam7777]

Hi.. I want to know, what is the mixing ratio formula of gelcoat, colour, peroxide, and others... Thanks

[@ecfibreglassuk]

Between 1-4% by weight, depending on the temperature and quantity being mixed.

[@entrad157]

This is a great tutorial on mould making but 3 to 1 resin ratio would produce a bit to much exothermic heat in the mould I have used 2 to 1 with great results.

[@ecfibreglassuk]

Hi depends where you are they are companies that can import, hope this helps best rgds

[@LowCostCncRetrofits]

Nothing wrong with brushing tooling gelcoat, spraying gelcoat is a real art NICE !!!
