Casting Resin Tutorial

[halopartyboy]

Im trying to cast a rather large rifle out of resin, where should my fill hole be? It has a carrying handle and I think that air could get trapped in it, but I also thought that I could use the barrel as a starting point for my fill hole and go from there

[coolbionicle]

@halopartyboy In my opinion I think it's best upside down with vents at the highest points and the fill hole at the highest of those, all that's left after that is tilting and burping the mold as shown here to let the air escape. I might be an amateur at this but I hope this can help :)

[gino7792]

can you sand and paint the resin once it has cured? can this be used to make car parts like hoodscoops?

[fishiesteethies]

Can you use a heat lamp to dry your resin?

@kendigj, awesome idea! I will see it done haha

[kendigjl]

When I die, I want my body to be set into a clear resin block. 

[wargamesanorak]

cool. I really want to start resin casting.

[linz4190]

How do I make my pieces colored? Can you add things to it prior or can you only paint after? Thanks

[MegaFoot69]

could i use caulk instead of silicon ???

[Emirichan317]

Can you sand the resin once it has cured?

[2degucitas]

Wow! These set up FAST!!!

[JohnnyDesaint]

i need to make a clear car lens.any sudjestions?

[legoprime2000]

could you give me some links where i could by all these materials, becuase i also want to start resin cast but i don´t know what material to use, becuase i am from Germany!!!

[Stresshead74]

Hello i take these must be low odour as you dont seam to be wearing any PPE or extraction fans so are these safe to use indoors

[JONIMASAKIS]

can i use ordinary silicone for mold? the one we put in a gun to glue on stuff

[kittioto]

Thanks for posting this! Learned a lot as a newb. :)

[kaewnarapat]

How you made a cycle tube lenght 100 mm thinness 1.5 mm. of mold

[babadocn]

I found it very interesting.  Could you please tell me where to buy the inexpensive resin ? I guess it's not toxic, right?

[teamadvan2]

Hello. I'm new. Have my silicone mould ready and started to cast things out. Pull them off after trying 5 cast, 12hrs, 24hrs, 3 days u name it. but i still get the same result. the finished casting products have tacky surface where finger print will stay there when ever i touch/hold it! What went wrong? Spray on wax are used. Very thin layer applied.

[guslingus]

Good little Vid Jim..

[DoctorWrath]

Could you please give me an idea of where I can purchase casting resin and RTV silicone? I've actually gone to a few places without luck.

[JimE2]

visit smooth-on. com for the resin, and bare-metal. com for the RTV silicone. I like the Smooth-cast 320 resin, and the l 71-20 silicone RTV.

[The3rdStrikeIsOnYou]

@DoctorWrath - eBay...

[pr5021]

the mold can be done in plasticine or resin is heated as it cools?

[JimE2]

Plasticine clay sometimes has sulphur that will cause the silicone NOT to cure, so be sure to NOT use those types of plasticine clays. But yes, a simple mold can, be made from P-Clay.

[KarriKoivusalo]

Hello! The problem with curing inhibition is inherent to platinum-cured silicones, but you can use tin-cured where platsil won't do. Major down-sides to tinsil is it ages quicker and shrinks a bit more with age, and actually is a platsil inhibitor itself. It's also nasty to prepare with 3% catalyst mixing ratio, but it just might save you from a "sticky situation" :)

[Psych0mik3]

what about fiberglass resin can that be used

[pr5021]

you know of urethane epoxy resin that is pure for use in areas of silver, white and gray? because I use an epoxy resin after adding in silver and white areas often with yellow reflect the sun made after several months and loses its clarity of clear ... you know any product in epoxy urethane or other product in the U.S. in sales in some clear epoxy urethane (link)?

[guslingus]

You can get special casting resins but they all tend to get very hot when setting "exotherm " This leads to cracking or distortion.

Plus i am yet to find one with very clear colours,,

Casting urethanes are way way better

[cherielsl]

Very good video, I have 2 questions:

Is that how they do most of the star wars resin blaster parts?? Can you add aluminum powder to the mixture to give it a metal finish?

[JimE2]

Yes, and YES!

[guslingus]

There is a UK product that is a very fine metallic powder you brush into the mould before casting.

The urethane then bonds to it and you can also give it a light polish afterwards..

[sendono]

Thank you!! ^_^ What does resin feel like? is it just like plastic or can you sand it to make it feel a little more coarse like porcelain?

[JimE2]

You can order different hardnesses, and you can add minerals and metals to it.

[tenzle]

that clear casting resin is so expensive .. is there a recipe to make your own casting resin?

[solrac88888]

yea but how do u make ur mold??? u know like when u want to make a repilca of anything

[JimE2]

Thats the RTV silicone mold making video.

[tiffanyblue420]

nice tips, this stuff is pretty complicated

[monnie110]

Is this plastic you end up with?

[knivesxout]

it's resin...

[monnie110]

Obviously lol that's not very specific. It's like when someone asked you what kind of car you drive and you reply back saying "it's a car"

[knivesxout]

well it's pretty obvious that it is resin, hence the title of the tutorial.

[DarthElk]

It's polyurethane, which is a type of plastic. I did something similar when I made my Zebraman costume -- I used Smooth-On Smooth-Cast 300, which is available in starter kits at some art supply stores.

[JimE2]

PolyUrethane.

[superskh]

how much would everything you need for this cost?

[JimE2]

Smooth-on has a kit to get you started. Cost should be less than $50-60 for making a small mold of a small part. A large project could run hundreds of dollars for the silicone alone. Depends on your project.

[MaximOfSurrey]

Nice vid. So just what -were- you casting in that anyways? I didn't get a good look at it since youtube's video quality isnt' the best.

[JimE2]

L2A3 Sterling parts, a tank sighting scope, and a mechanical counter.

[hamsik97]

Loved the video! Thanks!

if I want to cast a 2" bug with tiny skinny legs, how do I make sure the resin goes all the way to the end of each leg?

[JimE2]

Thats tough. Air entrapment on the legs would cause voids. You would need to add sprues, like extensions the model cars and plane kits have, to allow a place for the air to move to.

[fotograh]

how big of a mold will I need to make 1 ounce of resin mold?

[JimE2]

Depends on what you are wanting to make. 1oz is a pretty small amount. Thats about a shot glass worth of material. Usually silicone will need to be at least a quarter inch thick to support the weight of the resin.

[sail247]

could you explain how to make a mold for say a skateboard wheel for urathane? thanks

[mixymo]

excellent vid, thanks!

[rahurtadoa]

Exelente video mas por favor.

[1axvn]

JimE2 how hard dose the resin get, and can you get it in clear, can you polish it, will it shine, thanks.

1axvn

[JimE2]

depends on the resin used. Most are Shore 80 hardness. Thin parts will be brittle but that depends on the resin. Some are much softer. Yes, you can get clear, and if you can cast it without air bubbles, will look like water.

[luuko656]

what kind op material you use for the mold?

silicon rubber?

[JimE2]

Yes. Plas-Sil 7120. to be specific.

[luuko656]

aah same as i use now, ive bought a few liter of the resin and molding rubber...

i use it for small part and tracks for model tanks...

[infinite7z]

WHERE CAN I BUY THIS?? PLZ HELP

[luuko656]

you can order it on the internet..

[JimE2]

L2A3 Sterling parts,

[masterofrockets]

what is the cast of?

[PRICEJAMES]

Very informative. Good to know that I am not the only one suffering when making cast resins. It can be a messy time consuming job. Sometimes when I make a hollow resin cast in order to thicken the resin lining I add talc powder mixing it in, making it more gooey and that results in a thick resinj coating.

[aibakaneko]

NIce... I was always wondering how to casta mold and how th hell to get the white part. ahahha.. thanx
