Making a Vulcanized Rubber Mold

[@billfrantx]

Thank you, Lauren! I found a vintage vulcanizer and wondered how to use it. Your tutorial is very helpful. I'm looking forward to watching your other videos to learn much more. A+!

[@laurenseldenmakingthings7045]

Thank you.

[@stevelacher8092]

Awesome! I think I get the idea. I just wanted to make some discontinued automotive o-rings. You are doing a great job. Thanks

[@Jimbojenkins]

wow, brings back memories! used to do that back in the mid 90s!

[@soniaellis5333]

Thank you for this video. It's very knowledgeable. I'm learning to be a mold maker and I saw in another video from Rio Grande mold videos that they put a little dawn dish soap on the aluminum sheets and spread it so the mold can come off right away. Hope that helps you to not burn yourself so much.

[@laurenseldenmakingthings7045]

Ha:) I didn't realize I was burning myself. I'll have to watch again. Thanks for the suggestion.

This is a great job and I love making molds from Iraq a love greeting to you you are really a shepherd

[@rrbey3635]

You're really beautiful. keep on creating let your imagination fly much love

[@tallisholowka3946]

Great video..thank you! I remember one of my fellow students making a mold of my husbands wisdom teeth with this method. It "cooked" the teeth lol...made a weird nasty stink, but it worked! I still have wax copies of them.

Thank you🌹🌹❤🌹❤🌹❤🌹❤

Nice one

[@frannyfontana8597]

I have same one for sale if u know anyone that needs it comes with a few metal molds

[@lenny108]

12:29 nicely done, but this requires a professionally equipped jewelry workshop. In Europe they only sell silicone for higher temperatures to industry and not to private individuals.

[@Hugo777ization]

I use detergent to isolate rubber from aluminum plates top and bottom the rubber.

[@laurenseldenmakingthings7045]

You can also leave the paper on the outside edges. I never have trouble prying it off. I just try to introduce very few things. Thanks for the feedback.

[@jim9689]

Hi there! This video has a lot of good information in it, and I knew none of it before, thanks. I wonder though, why do you continue to cut and separate the two mold halves from each other -- it seems that if you stopped after you got past where the piece was and left the rest intact you would simplify alignment later. IT would also be great to see you use the mold and make a piece with it.

[@laurenseldenmakingthings7045]

As I mentioned, my cutting in this video is rough😂. I’d suggest looking up cutting rubber mold videos that are out there. I’ve left some together (you can); I feel like I mess up the pressure when holding it to inject wax. Cutting keys is the important part. I have another video with using the wax injector.

​@@laurenseldenmakingthings7045 good stuff do you make molds and sell them? Can you

[@chuckbeaver6473]

hi, nice video! can u tell me the name of the vulcanizer? maybe i need this too :) ty!

[@matthewbaker2573]

whats better please? vulcanized rubber moulds or liquid silicone moulds? is one better than the other for high detail? whats the life duration comparison? is one more expensive than the other would really appreciate a bit of insight - for i am a noob lol

[@Monkeeatbanana]

what composition if your rubber btw? Can i assuem it is 95% polyisoprene?

[@miguelangelinfantecorbo5401]

Pincelando talco justo en la mitad del molde puedes separarlo sin el bisturi .

[@UzunKamis]

24:30 Is there a particular reason to cut the mold all the way to the end? 27:00 Thank you for the tip. 😅

[@laurenseldenmakingthings7045]

I have left some molds closed but they tend to shift more when you inject wax. You really want large keys and a jagged surface so the mold has teeth to grab onto when you put it together.

[@jorgenava1726]

Un molde vulcanizado de una medalla o una estatua,es posible con la ayuda de un poco de petroleo hacerlo que aumente de tamaño asta un 500 por ciento. El molde en cuestion sehunde en petroleo,y este sehincha reproduciendo el grabado:una vez hinchado con cera de parafina se reproduce la ampliacion.a este proceso le llamé "jonapru",espero les sirva

[@alejandrohernandez916]

Thank you so much

[@laurenseldenmakingthings7045]

Thanks for watching. Hope it helped:)

[@amirulmukmin4965]

Just wondering.. Is that wax injection can be replaced by others material? Like ABS plastic?

[@CarlLatham-uc1cq]

You could use a plastic water bottle for your used blades and then just screw the top on.

[@theonlywaytogta6665]

Hi. Very informative video, well done. I'm curious if you'd share links to where we can buy/obtain the materials and tools you used here, such as the vulcanizer. Is a tire repair vulcanizer suitable for making small rubber casts?

[@laurenseldenmakingthings7045]

The tools shown here are older and the company is do longer available. You can search jewelry suppliers and tools in your area and you should see multiple options. Jewelry vulcanizer for rubber molds and jewelry wax injector would be the keywords.

[@jackrichards1863]

Why are we doing this exercise?

[@Amajoyas950-tp7mw]

tan simple era cora el exedente del molde y trabajar mejor.

[@MrAntonkuzmin]

You do not need to cut the shape out, just press the model in

[@harshvardhangupta1]

Hi ! At what temperature do we bake the silicone for 50 mins ?

[@laurenseldenmakingthings7045]

You need to follow the directions included with the particular rubber that you are using. All of them are a little different.

[@micylevandyk7222]

Hello. Where did you buy your heat plate press

[@laurenseldenmakingthings7045]

Any jewelry supply store.

[@vishal_soni427]

Hey can share me details where i buy system and raw material

[@laurenseldenmakingthings7045]

Jewelry supply stores. In the states, I often use Riogrande or Otto Frei, but there might be great jewelry stores near you.

apa nama mesin tersebut?

[@dahmanus2002]

it's a hard methode, without using rivets and talc to release the two parts of the mold easilly, you just need to cut only the borders with the surgical knife .

[@laurenseldenmakingthings7045]

I do agree. It’s just one way. I have used talc and keys in the past, however one or two times, I picked up a light texture from the talc and so I like having less interrupt the mold. I don’t cut them apart every day, but learned from a jeweler who was amazing at it. It takes way more practice to cut smoothly. Thanks for watching.

[@WhenDoesTheVideoActuallyStart]

I've saw a video of someone who cut nothing out, and just shoved the piece in there and let the rubber close in on it, and overflow from the mold. This also allowed them to use some paste as a mold separator to keep the top and bottom part of the mold apart. Wouldn't that be simpler? Thanks for the video!

[@laurenselden7063]

Depending on your shape, you can do that. You can also put little pins in place and use parting powder. Every once in a while, I can see the texture of the parting powder on the wax blanks. This is just one way. There are many. That's the best part:) Thanks for watching.

[@laurenseldenmakingthings7045]

There are a lot of ways to do this. This is just one. I have used parting compound in the past, but I found that sometimes it left a texture on my original pattern. I would then have to sand each wax to clean this up. You can also imbed metal "keys". Everyone has a way. Jewelers who have been in the field forever would have even more efficient methods. Thanks for watching.

[@pcka12]

Would the title Professor be as in French usage, or the holder of 'a chair' in a Chartered University. Definitions 'across nations' can be so confusing!

[@laurenseldenmakingthings7045]

Don’t know if I understand the comment: Professor at a university in the states- as in teacher.

[@pcka12]

@@laurenseldenmakingthings7045 Professor in France means Teacher. In the UK, the title is derived from the Roman idea of a heirachy of academics usually found in a lecture theatre & presided over by 'The Professor' who held 'the chair' in his subject; the more junior academics being Readers then Lecturers. My Dad eventually 'held a chair', I have only ever been a teacher or lecturer; So I suppose your equivalent might be 'lecturer' or 'senior lecturer'. The differences are interesting.

[@laurenseldenmakingthings7045]

@@pcka12 Thank you for the explanation. I am a teacher first and foremost, but by now (and by my rank), I guess I hold a chair.😜 I’m a Full Professor (in the states). I still have a massive amount to learn though and hope I always will.

[@frannyfontana8597]

I have same one for sale if u know anyone

[@sarkisdegirmentas750]

Hi Lauren thanks for giving us some tricks, but three tings you did wrong, first cutting shape of model in rubber no necessary and adding extra shit is also no necessary, then you don't need adding rubber between the legs, also never remove yellow stickers on both sides of the mold, that stickers not melting like blue ones, designed to not stick to volcanizer, ( Heating press ) by the way I have 52 years jewellery experience😊👍

[@marekslazyk]

[@kwidzius]

You video is really nice and some people will find it useful. Sorry to say though, but u have a very long way to go in order to become a mould cutter.

[@laurenseldenmakingthings7045]

Ha. Thanks for the comment. I totally agree. I never worked an an industry where I did many of them. I always self- disclose to my students that I have a long way to go. It requires touch, practice, and probably a master to show you how.
