Mould question
This mould of a semi flat tank was made for me. The maker also cast up some tanks for me from it.
I fancy making some more . What do you suggest using ? He didn’t use metal with this mould btw.
It depends what the mould is made from. If casting in metal not only would it need a pouring hole cutting, it would also have to be heat resistant. Even chemical reactions such as resin etc can give off heat and you have the extra issue of whether it reacts with the mould material. What did he use to mould his models? I'd suggest having a look at Greenstuff World. They have all sorts of stuff including a resin you mix with water: https://www.greenstuffworld.com/en/225-acrylic-resin Neil
I am also curious to know what the castings were made of - or even what the mould is made of and how it even works?! As Neil suggested for pouring metal it's usually made of vulcanized rubber of some sort and needs a pouring channel and smaller channels for air to get out.

Best to use resin; pour in the deep side and squish together
ReplyDeleteA plan , thank you.

Looks like it could work wirh sculpey. Press into both sides then bake with the mould. Demould remove flash ans fill in gaps between two halves
ReplyDeleteAnother plan, thank you.

ReplyDeleteHe made some for me using this mould. They are light and definitely not metal.

The various suggestions sound good but I'd suggest dustung the mould with talcum powder before use to reduce the chance of anything sticking.
