Depend where you are based. I use J Coker in the UK. There’s Nicem in Italy, which has a UK agent (Hewitt’s) and a US agent (Contenti). Plus Coniex in Spain. All offer silicone rubber moulding discs of various properties.
please can you help me, I can't remove the porosity in the 35MM pitch round rings, I inject the top right and the small air below, letting it come out of the rubber, but the porosity and holes always remain, do you have an effective remedy
Hello Mr Saunder, are you able to advise on materials that can be used to create the master pattern parts, more specifically 3D printed parts - plastics? Video is very good and instructive!!
I don’t yet use 3D printed masters. However, resin 3D masters are usually more detailed. But to stop the resin reacting with the silicone, you need a barrier layer, such as Release Agent J from Hewitt-Impex (Nicem). I’ve just ordered some to try it out.
Where do you sell your miniatures? Where do you get your original art work? I'm interested in getting started in the business but know nothing about it.
I bought an existing range, so I have a good existing catalogue of figures. New figures exist as notes in a notebook until I brief a sculptor. For historical figures I provide copies of existing art or old uniform plates; for fantasy/SF I often let the sculptor’s imagination interpret my written idea.
About 150 bar (2000psi) initially. The pressure increases naturally to 200-250 bar during vulcanisation. I just let it reach this pressure unless I am vulcanising delicate parts, such as plastic card. For delicate parts I’ll release pressure to keep it at 150bar. Higher pressure will ensure more detail is captured - too high a pressure may destroy the originals.
I use low temperature cream silicone rubber, which is 70 IRHD, supplied by J Coker of Faversham. Links to the suppliers used are provided in the text description for the video. In Europe, you might consider casting discs from Nicem of Italy or Coniex of Spain - there are probably others. However, I haven’t found a similar hardness low-temperature silicone rubber, only softer IRHD 55-60, from other suppliers. Coker sources its rubber from France.
In the U.K., SEBA (makes its own) or Hewitt-Impex (agent for Nicem of Italy). In the USA, Conley Casting. That’s if you buy new, otherwise secondhand ones come up on eBay. You can also buy mould cans that will work in a standard oven, such as the Vulcan mould can from Spinbox Casting - but they don’t give control over pressure.
A new vulcaniser is anything from about £5000. Masters can be made from many different materials, such as epoxy putty. You then cast metal production masters from the master mould to make a production mould.
"After you put your mushroom, in remember your nuts." Words to live by
beautiful collection
Thanks for the complete tutorial I have a problem. When I do formatting, your lead work is different from the sample What is the solution?
"The most important thing after you've put your mushroom in is to remember your nuts." Wise words indeed...
I have contemplated making a large sign... :-)
Sir can you please tell which grade silicon rubber used to making moul for casting aluminium parts
As far as I’m aware there isn’t one. Aluminium melts at too high a temperature.
Amazing where can I buy that silicone for molding

Sir small dout with stone ideya good r bad
Where can I get all the stuff for this
See video description
👏👏👏👏👏👏👏👏👏👏👏👍👊

Hard to answer without pictures, sorry.
Can i make brass pieces this way?
No. Brass melts at too high a temperature for silicone moulds
Please say what type of silicone this is thanks
Details are in the text description for the video.

Sorry, I should be clearer. All my figures are sold on my online shop, which has just been redesigned and moved to www.fighting15s.com
Hola! Como se llama? que caracteristicas tiene esa silicona? Gracias
J Coker’s cream silicone is 70 IRHD and cures at 90 degC
How much are the vulcanizing cans?
I think one will cost between £400 and £500 nowadays
من أين اجد هذه الأقراص هل بإمكانك بيعي
Where I source the discs is listed in the description for the video. Where they are available outside the UK, I regret I cannot answer.
A que presión inicial le das,y después lo sigues subiendo la presión? Por favor quiero aprender, gracias.

Mujhe karigar sahiye sir
temp at 85 c at what pressure?
See ruclips.net/video/mFyGCJAEqQA/видео.html I typically use around 2000psi/150bar, but it depends on the nature of the masters.
Hello, I have a question, are you in the United States? Where do you buy silicone zamak and other inputs?
Sorry, not in the US. Try Contenti (contenti.com)
Where would you get a vulcanizer for something like this?
In the U.K., SEBA (makes its own) or Hewitt-Impex (agent for Nicem of Italy). In the USA, Conley Casting. That’s if you buy new, otherwise secondhand ones come up on eBay.

Jawellray kese banate hai pura detail dekhaye sir please
Hi
I want to make medals, but I do not know the material from which they are made. Is it silicone or clay? And how much is the machine?
A new vulcaniser is anything from about £5000. Masters can be made from many different materials, such as epoxy putty. You then cast metal production masters from the master mould to make a production mould.
Pewter cost has gone out the roof recently ...........
It's certainly not cheap. :-) It made me at last melt down some redundant stock, because that was cast in pewter bought at half the price.
Hello, do not be bored, it is possible to send me the molding video
Casting machine
I use a Saunders MK V. I plan a video on this in future. But currently I'm a bit busy with work
Very slow 🐌 is your work
I’m doing a demonstration not running a speed trial 🙂
