C'est super, very nice vidéo bon courage

[@sambora.jewelry]

good video as always. I don't remove the paper labels from bottom and top layers of rubber - easier to remove the plates after. And I put everything uder cold water to cool. It is a recommended by Castaldo method.

[@mudbouggin7563]

Would you mind providing a link for where you purchased your wax injector? I like the idea of a hand pump wax injector as opposed to a air compressor wax injector (and also the wax you use)

[@ClearMindJewellery]

Our injector is a much older version of this one: www.gessweincanada.com/product-p/265-2235.htm We change out the wax depending on what kind of model is being injected. Pink for high details and thin sections, turquoise for general use and purple for models that will be altered/carved after injecting.

I use a large syringe heated in the oven. An ok way to start.

[@mudbouggin7563]

​@@CONEHEADDK not a bad idea, but I'd like something with a better seal to the mold

[@CONEHEADDK]

@@mudbouggin7563 My molds are clear, so I can see, if they are filled. But I suggest just filling them hard, and then - if the wax is warm/fluid enough, the extra just flows out. Who cares if you have to redo a few of them - wax is reusable. If you only have a few molds, drop them in cool water after filling, so you don't need to waste a lot of time. I have a bunch of syringes, so I can do a handfull at a time. Not that I am "up and running a production", but that's mostly bcz I don't really have the burn out facilities. Tne seal against the mold isn't really a problem - just press it "hard enough", and reuse the spills.

[@carlericvonkleistiii2188]

Thumbs up from reddit!

[@christianblack2916]

I don't understand where the air in the mould cavity goes when you inject the wax! Would it not form bubbles and resist the inflow of wax unless there were vents? I'm glad it works all the same!

[@ClearMindJewellery]

You can do relief cuts in the mold. Generally we have found this isn't needed unless the model is highly detailed or small. Although we try our best the two sides of the mold vary rarely make a perfect seal meaning the air will slowly leek out on its own for larger more generic models. We will be working a new molding video in the coming months as this one is missing some information and we can do a better job of explaining now.

I know the video is old and probably won’t get noticed under the latest lot of videos you’ve made. Where can I get the separation cream from and what could I use instead of the cream because I’m finding it hard to source some out? 🙂

[@ClearMindJewellery]

Any talc based product should work. Look in the hygiene and baby aisle for something comparable. At this point, Castaldo has moved most of their manufacturing to Thailand, so some of their resellers are having a hard time getting their products.

It depends on the type of item you're injecting. But generally yes, some type of clamp or other way to apply equal tension is a good idea. This video is a little old and we are thinking of making a new video with our updated process.

I have a question, how much melted wax temprature?

[@coulterjb22]

After you place the mold on the wax injector you pull up on the plunger. Does that in any way create a small vacuum inside mold?

[@ClearMindJewellery]

I've like to think so, but I don't think it works that way. Pulling up draws the wax into the pump, so there must be some kind of check valve inside.

[@rushka1354]

Hi. Just saw your video. Awesome. To date we hv been sending molds to casting and they inject. Now we are injecting ourselves. Any advice on why wax is going in creases and forming webbing spillage? Any advice would be greatly appreciated. Also how much powder do we apply? If there is talc on wax once removed from mold. Will that show in casting - washed off most of it. Thx again

[@ClearMindJewellery]

Creases may be because the wax is too cold causing overlaps or ripples, it depends on what you mean by creases. Generally you should only have enough talc on your mold to produce a matte finish on your wax models when you pull them out. Not seeing the actual powder stick to the wax. You may have a slightly textured finish on your models after casting if there is extra talc on the surface. If you can get a nice shiny injection you will get a nice cast model.

[@sonuverma2796]

Sir I use liquid and castaro rubber both but casted piece size reduce ,compared wax size and original piece both , so how to control shrinking problem solved, I want to cast Silver coin but it's not equal original piece size and weight both less compare original piece , so how to control that problem

[@ClearMindJewellery]

Sorry but I'm having trouble understanding your issue. When molding and injecting you have to be aware at every step to limit shrinkage. The No Shrink Pink from Castaldo has little to no shrinkage you also need to do your research on a wax that has the same no shrinkage properties, none comes to mind at the moment. Also use a polishing method that removes less material to avoid too much metal loss, such as only tumbling the item. When we make items that need to be a specific size, for example rings, we will account for the shrinkage rate when making the model.

[@judeb2127]

I'm not an expert but in the video they used "Castaldo No Shrink Pink" specifically because it has zero shrinkage. Hope that helps :)

[@sonuverma2796]

Your mean I used pink colour castaralo rubber instead liquid rubber to control shrink

You need a specific setup to handle steel and platinum. The casting machine will be different, better heating capabilities and gas shielding.

any benefits to using vulcanized molds over liquacast?

[@ClearMindJewellery]

Vulcanized Pros: more durable, combined/ layer different rubbers, option not to have to cut apart, generally slightly cheaper, they’re faster to make Liquacast Pros: no heat, higher detail, some can be clear, size options

What are the benefits of doing this method as apposed to 3D printing

[@ClearMindJewellery]

Todays video actually goes into that in the intro. kzbin.info/www/bejne/rqKaaauHi9eFoKs To summarize. Speed and cost. If you don't have enough items to fill the print bed or have so many items you need to do multiple runs its time to think about mold making.

[@CorniiYT]

@@ClearMindJewellery will add to my watch list does this also work for earrings?

[@ClearMindJewellery]

@@CorniiYT molding is for making the design element most times. Injecting earring posts is hard and making multiple molds for every ring is a lot of work. So mold making has its place when you're making standard design element and then you add on a ring blank, post, or other finding. or You are doing high volume. Then making multiple molds for each style in each size makes sense.

[@gcclarke1]

Great video. Would you guys be able to give an estimate on your up-front capital costs for the system you've setup?

[@ClearMindJewellery]

Gregory Clarke For the molding only or the entire casting setup? I picked the vulcanizer up used and it came with a small assortment of frames for $250 I think. The rubber is about $60 for 5lbs which will make a lot of molds depending on size. Around 15 of the size that I showed in the video.

Can the rubber be recycled?

[@ClearMindJewellery]

The rubber once vulcanized cannot be reused I am not sure if it can be recycled.

[@flatmoontheory]

Hey Guys! Is it possible to make one of these vulcanized molds with a 3D Printed Part? Or does the vulcanizer get too hot and melt the PLA?

[@ClearMindJewellery]

It’s to hot. You can look into a cold poor mold like liquicast, did a video on making a mold with it. You can also cast PLA directly with the proper investment and burnout.

[@flatmoontheory]

@@ClearMindJewellery Thanks so much! We (my wife and I) would like to know what is the best way to "mass produce" a PLA Print? We would like to make some sets of Silver Jewelry for our grandchildren and their parents, but 3D Printing each item seems like it would take far longer than injecting wax for a spru tree?

[@ClearMindJewellery]

If you’re only making a few pieces I’d just print each one individually, the overhead cost for each piece would be lower overall and use less materials. For mass production injecting would be the way I’d go with multiple moulds of the same piece.

[@flatmoontheory]

​@@ClearMindJewellery This is very helpful information, thank you so much for taking the time to reply. One last question! With your helpful guidance I've watched the liqui-cast video you posted and also looked at Gesswein's website at Castaldo clear-cast products. What would you say are the advantages to going for a full vulcanized mold over a clear-cast (besides possible degredation)? Is vulcanization going to give you the ultimate in fine detail, or is clear-cast at the point where the difference is negligible?

[@phillipklingelberg7095]

Hi there. Is it possible to use the method to produce a large ring with a ring head twice as large as the ring rail. I mean with the "BANANA" method. The scalpel method should work or not? I want to copy a "brutalist" ring. THANK YOU.

[@ClearMindJewellery]

This method will make a mold out of anything it is the success of extracting the wax from the mold thats the issue. If the top of the ring is too intricate it will be difficult to remove the wax. After making the mold I would make a few relief cuts in order to facilitate this.

[@ClearMindJewellery]

For our workflow we prefer to use direct to cast resins. However there shouldn't be a problem with making RTV molds, like the liquicast video we did, vulcanized molds might work but it would depend on the heat grade of your resin. Definitely check the spec sheet first.
