Thats great you have a lot of art there. I thought you had sped up the camera! Can I ask how long and at what temp would you vulcanise a 4 layer ring mold, vucanising only one mold at a time?

[desantisjewelry]

the temp can vary. would recommend going by the manufacturers suggestions. it's usually 6 minutes for each sheet at around 260F

Nice job. Although that was two different moulds.

I never make bangles so don't work with moulds that big. How many layers did you use? What are your settings on the wax pot? Again, nice job!

[desantisjewelry]

Yes, good eye. It is two different molds. the mold being cut is 18 layers, and the finished mold shown at the end of the video is 24 layers. That has so far been the largest mold we have made. We inject using rougly 10psi with a wax temp of 150F. Thank you for your compliment!!

Awsome job bro! I really hate cutting those big molds.

[desantisjewelry]

Thank you. You really give your forearms a good work out when cutting these size molds.

I cringed the whole time, I am a professional and this is utter butchery. Hands so weak you need to use curved blades & hand placement akin to a gorilla. Four fingers laid across as you are cutting, I am shocked you still have any of your fingers at all. You appear to be proud of yourself, but you lack technique. Those undercuts are so sloppy, only the miracle of Castaldo Gold Label saves your handiwork. Your swivel cuts for minimizing slippage, LOL surprised the two halves mate together. CRAP

@menappi you can reuse this mold hundreds of times, and it is made out of castaldo rubber.

[menappi]

I wish there were more videos like this on here. Question- How many times can you re-use this mold? I want to have some molds made and I would like to get hundreds, if not thousands of patterns out of them but I'm not sure what material to look for.

@xxxkahunaxxx You don't pour the molten metal into this mold, you inject wax as a way of duplicating the original piece. The mold is originally made around a metal form though because it needs to be heated up.

[menappi]

This is great for beginners like me. One question, how many times can you re-use a mold like this (compared to a rtv mold). Can you make a video of the making of the mold before it's vulcanized?

U are good, very good thanks for sharing it with us

[keysthinking]

I tried to cut my own molds for years and could not. You either have the skill or not!!

And you my brother do a FINE job.. Great video

[xxxkahunaxxx]

ok, i watched til the end and i see that the rubber mold is for molding the wax...i guess that is used to make the real mold with the investment compound...great video by the way!

[xxxkahunaxxx]

how does the rubber not melt when the molten gold is poured into it? i would love to try making something out of gold, i have already made a gold blob, now i'd like to turn it into something with shape!
