Casting your Parts in 30 Min (No silicon rubber required !!!)

[rallymaster]

I received mine this morning...
just have to test it now

It will be very usefull to cast some parts but not very adpated to other like tyres I guess...

I will also try to use resin in oyumaru molds as I haven't two parts putty at the moment.
(will try to find some tomorrow)

I have seen few tutorial in the internet using resin on oyumaru, but I never try this myself. I think shouldn't have any problem at all

i bet the searches for this just went up a thousand fold.....

Of course, I bought it on a french online store (the "expensive" place I was talking about ) and finally discovered that there was a 20% discount on the item.

Then I paid less than 16 euros for two boxes sent to France in 2 days.

here is the link to the item in the store:

Interesting, but what about detail reproduction? The greatest advantage of silicon is its liquid character, which enables accurate reproduction of fine surface details. What about this product? Could it capture scripts and emblems?

I might have to try this, time saver for small parts!!

Would this Oyumaru be similar to Utile-Plast?

Utile-Plast is readily available in hardware stores (like ACE) here in our country and somehow has similar qualities ('cept for the candy colors) to Oyumaru. Might be a good alternative to Oyumaru?

Never use Utile-plast, judging from the shape it looks like shapelock(usa), polymorphe pallet(UK). Yup you can make mould with it but the only problem is when it cool down. It is solid hard, and it is very difficult to demould

Hi guys,

just to let you know that yesterday evening I prepared several 1/43 parts I've been needing to cast for months to be casted in resin with oyumaru molds...
I wil let you know the result but I'm really confident, this product really sounds like the easiest and quickest possible to use to cast some poor detailed parts.
(I still believe I won't cast high detailed structure tyres or something like that but it will surely be usefull for almost everything else !)

Hi guys,

First test, first results

I didn't cast anything since a long time, so the results of these tests can be improve with practice, I think I didn't do as weel as my last casts...

The first thing to say about oyumaru is there is no problem casting with resin.
that's what I did.

second thing, It is not as performant as silicon resin, it is harder to do a proper mold to cast details because of the nature if the product (not fluid) but that's what makes this product simple and quick to use...
So see biths sides when thinking to use it and think to advantages and disadvantages of the two methods.

I tried to cast 1/43 rims and inserts to fit in, 50% is not perfect, not complete, the other 50% is nice.
But I can't swear problem isn't my lack of recent practice and the resin mix I did maybe not good enough (resin and hardener) to easierly fill the gaps...
or maybe simply the fact 1/3 is harder to cast than 1/24 ?

In fact I think I should have done that a different way to put resin inside the molds, maybe vertical chemneys or more chemneys...?
I will think about it next time.

I don't know exactly what but I did something wrong even if Oyumaru can't catch (small) details as silicon resin (which is fluid), because nevertheless it works quite fine for half of my parts !


the parts themselves are still drying so I only have the pics of the molds I did for the moment,I will take pictures of the parts later in the morning or day when completely dry (I don't want to take the risk to ruin my work )















My advice would definitely be to buy some (that's far cheaper than resin) and try yourself, you may achieve a good result with most of your simple and/or large parts.
casting details will not be easy but shouldn't be impossible...
I think it depends on your skills (I have big lack of casting practice these last years !) and on the resin you will use with, if using resin of course.
I didn't try two parts epoxy but that could be the best solution.


here are conclusions for the moment, If you don't care I'll put pictures of the parts later...

There's a similar kind of product on Ebay try this http://shop.ebay.co.uk/?_from=R40&_t..._nkw=polymorph I've often wondered if this stuff was worth trying, so a big thanx leokc_ng for this tut

or for Oyumaru itself in the UK http://www.artclayshop.co.uk/product_details_183.htm

I did try polymorph before, the main problem with polymorph is it is solid hard when it is cool, so it make it very difficult to demould.

ok, ok...

i've bought 6 strips of this new thing...now i need to do some casting off metal parts. i've read all the posts here too.

please contribute more if you have any feedbacks & results...i need them to guide me here. this is my first time casting in any form!

help!

Don't worry Marc, IMO you'll do fine.

All I can say is: "trial and error". You learn best when you try it yourself.

Good luck and keep us updated!
