PEWTER injection mold! Does it WORK? Is it dangerous?

[Music] the current episode i'm filming is currently being filmed but i ran into a shipping delay on a key essential ingredient so i decided to switch gears over to something that we have not done in a little while [Applause] we have made injection modes using a variety of techniques like resin mixed with iron oxide silicon specialty high heat silicon inside of a metal frame we've also made 3d printed models and 3d printed miles inside of aluminum frames [Music] and other variations on that idea now i have made pewter push mode [Music] there we go well push mode you one that you push together to form the material or you know a one part mode that you push the material down into but what about a pewter injection mode and this is a question i have received before now all the way here sort of answered this question not only would the surface finish not be as good with a pewter or aluminum mold because it would be pity and not be smooth my main concern is it starts to melt at 400 degrees so you know i said let's just see what happens if we actually try this don't here goes one of my figure designs i look at this as the prototype of the figure that i eventually want to uh produce because we've already changed this design made some of the parts better for melding did draft angles and made the figure reversible uh more modular and most fun stuff so that's the idea fo for some day down the road i really want to see this happen but for now the old design will work for illustration purposely even though this silicone is not designed specifically for high temperatures like mold max 60 silicone is very decently heat resistant in a way and for anybody interested this particular silicone is smooth on uh umo it's not as tough as platinum cure silicone but because it's tin curl silicon you can make a mold of the original resin 3d prints without worrying about uh cure inhibition and getting a gooping mess and no acrylic spray sealant required i like to add me a little powder to my mold uh this one is cornstarch based by the way so that's that's better than some baby powder but the powder helps with the surface tension to allow a better flow please please be careful anytime you messing with this because it's hot it is high very hot craft man what temperature does that meant that now some of these are pewter and bismuth and different type alloys and different metals the low tim you looking at probably around 400 degrees afresh i didn't have my laser thermometer out here to get a temperature so i accidentally let this one go a little bit too hot as you will see whenever you do this please resist the temptation to put your finger down in uh to try to get the bubbles at all right we're going to talk more about that [Music] now i can already see some couple three problems with the models as it is but uh that's what it turned out like right there but let's try to inject some plastic into the see what happens now remember that even though you might be injecting plastic this might have a 400 degree you know around that or a melting point or into a pewter mold daddy on the dangerous side of things that right it ain't going to immediately just melt to nothing the heat has to uh transfer to conduct and to build up to actually get the temperature of the mold to there but craft man knows from experience with metal mode or although they conduct different aluminum modes sometimes get up to 150 or something you know degrees and i might have to cool them down if i was using a pewter mold i would probably have me some water nearby and would feel more comfortable cooling that mold off here for a couple shots you know this particular material is a thermoplastic them that melts between 360 to 370 degrees and i like it because it's rubber flexible and tough and it's orange color right there again i just want to emphasize this not something i recommend please don't try this i'm just i'm basically answering the question you know and seeing if this even can work all right so we got us apart now i knew some of the details was messed up because you know the mode was messed up and why is that well whenever i pour reds and moles i like to take a toothpick a finger something and go around there and get them bubbles out we don't need no bubbles in the mouth no or either put it in the pressure pot but that's not really for me an option with pewter either one of them but we can see these rounded edges right though and that's all because that thing did not flush the metal did not push into them cardinals was really what happened is it possible to take a piece of metal or something yeah maybe probably i don't know but i just really don't feel safe using pewter an alternative that is much better would be to use aluminum if you want to pour your mold i'm not so much a big fan of part models because it tends to give a pitted sort of texture because the metal is pitted now you can do some filler aluminum high heat aluminum epoxy filter and get you a smooth surfer so going forward craftsman's two options that i look it is if i need to make buku or something i'm going to have a metamode cnc'd out of aluminium and if i want to do a more shorter run and i'm just going to 3d printing with soraya sculpt or soraya clear 3d printers i hope this video was informational and fun for you to enjoy it always feels like cheating when i put out one of these little shop logs like this but like i said i'm about two three days uh from getting the materials i need to complete my my little shop or a diorama that i'm working on but thank you for tuning in i hope you staying cracked and staying happy and i just appreciate you taking time to watch this video i love y'all and keep on still look crafty or steady crafting all right so you
