Darrell has got his hands on some Instant Mold from the CoolMiniOrNot website and he’s not afraid to use it.
This sort of stuff is quite handy for helping mass produce scenery pieces you may have made out of plasticard like windows doors etc. depends on price though as always.
I forgot that part, it was quite expensive with the shipping to the UK when it first came out so it put me off, not checked the price recently and I have no idea if it’s stocked in UK hobby shops.
I forgot that part, it was quite expensive with the shipping to the UK when it first came out so it put me off but checking with Google:
Cheapest is Firestorm Games: £10.79
Then Gifts for Geeks: £11.99
What you do with it then is only limited by your imagination (or GW’s copyright, whichever hits the wall first )
That price is flat out disgusting simple as that.
For those who do not know “Instant Mold” is simply a re-branding of a Japanese product called Oyumaru.
Oyumaru can be bought in the UK for around £5 for SEVEN sticks making it a quarter of the price of Instant Mold for the exact same product.
The only difference is that Oyumaru generally comes in a mixture of colours, as it is often marketed as a children’s toy, but it is still transparent and it isn’t like you need to see through a mould anyway.
Some links to UK suppliers:
Same stuff available for £4.90 + £2.80 delivery, even cheaper!
I tried to post the same link but for some reason it has been left at “awaiting moderation” … perhaps I showed my disgust at Instant Mold’s pricing a little too strongly.
Here is the other link I tried to post.
£3.83 + £3.95 next day delivery.
So that’s £7.78 for Seven Sticks of mixed colour.
Fredaldous’ £7.70 for Six Sticks all of the same colour.
Or Instant Mold for £10+ for THREE Sticks.
It’s sort of expensive for teh quantity… But you only need one pack ! You can re-use it ad-infinitum, just put it in hot water again… It works very well with green stuff (which is pleasantly flexible once dried, and just pops right out of the mold), for reproducing armor pieces, ornaments and such, and making them “en masse” to glue to other minis to have a unified theme to an army.
That’s my plan for my Chaos army: make a symbol once and then duplicate it with Instant Mold and stick it to all of my Rhinos, etc.
Its pretty good stuff, as you said works great with GS, tried using it on some milliput and it damaged the compound (the were flecks of milliput stuck in part of the compound and that section took much longer to soften than the rest).
I like the idea behind it, though I’ve not used it myself but I think one of the other selling points is that it is reusable, so if you don’t like the mould or want to make a fresh mould just heat it up and start again, genius.
I have used this for some push molds with green stuff np but have yet to try a 2 part mold
Itd be great if you coudl do a detailed tutorial of how todo a two part mould with resin etc for us simpltons who have never really tried casting at all.
i been trying to copy using green stuff, would resin work and not melt my istantmold?
You can use almost anything – as long as it doesn’t heat up while it sets.
Can you make one big block out of the small blocks by heating and mixing together (like plasticene)
Your problem is getting the larger lump up to the right tempreture and then manipulating it afterward.
Darrell has made a two-part mould from this stuff… hopefully he’ll be making a video on it soon.
Ive been making some pretty cool stuff with this using super sculpey firm, i find it works really well if you want a detail that can be easily reworked to be your own
Darrel’s Barrel’s ! love it. It’s useful stuff I think – but not good for casting miniatures or more complex stuff, at least not inless your a pro with that kind of thing. I found it useful for casting terrain pieces and more simple 1-piece moulds though. Used it to make the evil black hatches, book shelves and artefacts for terrain for my Yithian/Flying polyp skirmishs.
And sold. Watched the vid and ordered immediately. Been waiting for something like this for a long time. I hate the cost of silicone and it’s quick degradation. Not to mention re-usability.
This product seems ok but will not work on any sculpts or models made in soft materials, ie plastiscene or sculptors wax, the heat and pressure would affect the model, I would also be concerned about using resins to cast as these can become quite hot and will probably distort the mould. This type of moulding is quite crude but would be helpful to moulding small items. I think there could also be issues around air bubbles which will result in alot lot of filling and cleaning up time. This seems slightly gimmicky and would probably suit somebody that wants to try their hand at easy moulding, as an introductory step.
I do a fair bit of moulding and casting of my own efforts, not miniatures, but scenery pieces and details. I use high quality silicone, expensive but the best, moulds and casting resin. I also built myself a vacuum chamber to get perfect casts everytime. This can take along time but helps with mass production.
I am willing to give advice on any moulding and casting questions you have. Wax on wax off.
Thanks @bishmeister. How to build a vacuum chamber for casting would be good to know, as would practical recommendations on different types of materials for casting. There are quite a few different types on the market and it’s not always easy to find info on how to pick the most appropriate type.
Have used a two part resin from the car parts shop Iy does get hot if there is a big mass. Have had it start going off, and a big lump in the container heats up.
However, the small amounts poured into the mould seem to stay cool. Assume any heat from the raction is dissipated rapidly, or there is not enough mass to generate heat in the first place.
The big problem for me was that no matter how carefully I poured and mixed the resin there were a lot of pin holes from the bubbles. Luckily for the terrain I was casting it ought not be a big problem to fill them or just call it battle damage! lol
usable with green stuff eh? i can get that cheap (£0.25 per inch) and with this my nice fancy bases should (hopefully) come out looking really nice, will try it out then if it works try something a bit more complicated. Thanks for this darrel and @philld77 for getting links and prices.
can you reheat the mold and reform it?
Yes, you can ! See above.
so would this literally just be a case of when you have the mold stuff it with (in my case) greenstuff, wait for it to go hard (that’s what she said ) then take it out, sand down if needed and you have the item a second time?
Yes, it is ! Quality may vary on larger pieces, but it’s basically that.
sweet, definitely gunna get some.
Sorry the above video was the wrong one.
This is the right video showing examples of Oyumaru (the original name for the product that Cool-Mini took and re-packaged as Instant Mold and charged 4 times the price for) being used for 2 part moulds.
You can also use it to make larger two part moulds in the same way you would use latex/plastic moulds, it is less durable though so best only if you want to cast a couple of pieces.
Resin can be used with this but you should experiment and probably just to be safe don’t use quick drying resin as that tends to heat up more than regular resin so could possibly deform the mould.
Certainly a bit of trial and error to get the best results but you can do a lot with it past the basics of making simple push moulds of detailing.
That´s right. Got a pack of 6 stripes of Oyumaru for half the price, so the “charged 4 times” is spot on. If you have a hobby store in your town (even one for crochet, broidery etc) go ask them if they can get it for you. Bigger Toys R Us stores might have them as well, in the the plastic jewelry section…
Found this on on amazon under the oyimaru name in the UK, £4.90 for 6 sticks.
I have found that instantmold works really well for one part molds but making a decent 2 part mold out of this stuff in verry tricky not inpossable just verry hard it took me about 4 attempts before I had madedged to make a decent mold and even then like darrel said it is hard to allign the mold again so overall I have found it really usefull but like all things it has its limitations
The best trick for aligning 2 part moulds of this sort I have seen is to take a couple of Lego bricks and push them top down into the first part of the mould at opposite corners, or all the corners if you want to be very sure.
When that has set you can take the piece of Lego out and it leaves a nice little Lego shape in the mould so when you come to put the second part of the mould on top it goes into that and creates a lock of sorts.
Some vids here A little slow but worth bearing with as you get some great technical tips imho http://www.youtube.com/user/MadCowCrazy?feature=mhum#p/u/4/E69V3UkCJxE This is part 1/5 hth
A great product and even better that it is re-usable!!!
Thanks to Tiger for the tip on using Lego to align 2 moulds.
Ordered some and cant wait get moulding.
Would just like to add in regards to aligning 2 moulds was that I heard placing small marbles in the first mould so that the 2nd one sits in these holes…
I bought it, and I think that it is great. I plan on using it to make legs. Also it is great for conversions if you need 2 bits but you only have 1
Another thing you can do for aligning is to use your wife/girlfriend/moms old compact case for make up. Of course they need to be somewhat thin items you are doing. But you put the insta-mold on each side, put your item in, and the close it. You just need to mark where the mold is on the case with a marker or something so you can position it in the case every time or just use blue tack to keep in in place.
What resin does anyone recommend for replicating bases or small parts for miniatures using this mold?
Total noob at resin and would like a choice rather than using green stuff…
It’s a great product. I have used it to make copies of chaos lightning claws, chaos meltaguns, terminator cloaks, thunder hammers, storm shields, some blood angels melta weapons, chaos dreadnought sarcophagus, shoulder pads… and more. It makes it a lot easier to have a WYSIWYG army when you don’t have to but x# of box sets to only get a weapon that you need that bit selling sites are selling for 1/2 the cost of the whole box set.
how the hell did u get lightning claws with this??????………its the only think i couldnt get right??
