THIS IS PROBABLY THE BEST MOLD MAKING VIDEO ON THE INTERNET

[@Gurujiblessin]

Little correction, not only on internet but on earth. The best explanation and demo.

[@tomstern1681]

Might be the nicest silicone mold I've seen done

[@bjbenterprises]

Wow, thank you very much. We try to show some of the best tricks in the mold making process so our customers have the highest chance of success making great parts.

[@mdreedify]

I am brand new to resin-ing. I'm miles away from pouring my own molds, but I have so many awesome ideas that require I learn how! When this video popped up I knew I had to watch it. (Actually I had to watch it a few times bc I didn't understand some of the silicone/molding jargon the first times, that's how new I am to all this lol) But wow!! Did I ever learn a lot! With the simple, easy-to-follow instructions and your skilled guidance and explanations, this looks totally doable for me when the time comes. Thank you so much for sharing this with the public. Very appreciated.

[@neatpleats11]

This video is one of the best training video's I have ever seen. Fantastic job.

[@zhang_han]

Excellent tutorial. You know you have a rational, technically minded instructor when they've opted for a tungsten ring over a gold one.

[@bjbenterprises]

Haha, good eye!

[@LaylaMiki]

It's definitely the best "how to make 2-part-silicone mold" video on youtube ! Everything is clear and informative. Thank you for your amazing job !

[@bjbenterprises]

Wow, thank you! We do our best.

[@Grim_Falcon]

Brilliant, Brilliant, Brilliant! Thank you so much, I am a South African so there is very little chance that I will be able to do business with BJB and yet they make this content available to all of us for free. High quality, in depth detail regarding the holistic process. You guys are as generous as you are skillful!!

[@bjbenterprises]

+Grim Falcon Wow, thanks for the compliments! Although we've pretty much shipped all over the world, getting product to South Africa is indeed expensive from the US.

[@CMCustom112]

One of the best tutorials I have seen on KZbin. Good job sirs.

[@tjfSIM]

I have to say this is by far the clearest, most helpful and informative video about casting I've seen so far. Really helpful, thank you.

[@corpseesproc]

What a great instructional video! You covered everything I have been trying to figure out myself thanks!

[@pkdiealationzcc]

EASILY the best video I've seen on the topic, by far. ..Very professional and informative but still kept it as simple as possible.. Keep up the great work.

[@dieple3490]

I rarely comment on any KZbin videos but I have to now because I think you guys deserve it. One of the best tutorials ever and exactly what I need!! I'm jumping onto your website now. Please keep up the good work!

[@bjbenterprises]

Wow that is awesome! Thank you for the kind words and we will continue putting out great content!

[@tubeflorian]

Just found this. Extraordinary in every way; content, delivery, and production.

[@bjbenterprises]

Thank you!

[@karlphillips3035]

A very good video. Comprehensive coverage on everything. Very well presented and with ALL the details that are so lacking in so many others. Great. Thankyou

[@Triad3Force]

Wow this is like "next level" mold making. It looks so precise, clean and professional!

[@supergiantbubbles]

I'm super impressed with the care taken to very clearly detail the mold making process. I can't imagine a better mold making tutorial.

[@bjbenterprises]

Hi Dustin, thanks for the compliment. This video is representative of our company's knowledge and experience in this industry. If you have a project or application that requires mold making and casting, consider us as you source! [e-mail]

[@ketcyrobles5165]

By far the most clear informative video I’ve seen. Great job !!!

[@brianwolf9052]

This video is extremely informative. Thank you.

[@szabogabor6823]

Definitely one of the best tutorial I've ever seen!

[@ytfp]

I found this tutorial exeptional in explanation and found the detailed reasons why a certain procedure is executed very helpful. The teacher was very clear and professional in speaking and was easy to understand. The lack of any background music was also very much appreciated as it was not present to drown out the presenter and also because I suffer from misophonia, a hearing condition. Thank you very much for your very well presented presentation about your products and the processes in which to use them effectively.

[@dajanamicunovic4677]

[@lesleyjohnson4434]

I'm with the crowd on this one! I've watched dozens and dozens of instructional videos while I've been learning the silicone mold making process, and this one is like an epiphany. Thank you for the clarity and for sharing your skills.

[@bjbenterprises]

Not sure how 133 people can thumbs down your efforts, I think your vids are brilliant - cheers :)

[@bjbenterprises]

Thank you Lee, we're not sure either.

[@slimplynth]

@@bjbenterprises I worked it out.. jealousy :) keep up the good work. i've only recently started to master 3d printing but you can't beat PU systems by the looks of it, for repeatability and speed.. i just know your vids are going to help me no end in my new job role. A million thanks for disambiguating it an making it look easy.. 10/10 from me :)

[@2techshop]

Excellent video!

[@Syx7h]

thanks for this video. great job.

[@digimaks]

AH! Plenty of thanks! I am learning to make molds and casting, but was not aware of the feed and vent tubes, and how to position them. I seen some examples when peple pour resin into the first half, and then place the top mold part on top- but that will surely guarantee the pry line, and maybe some stubborn bubbles.

[@andynoiseboy]

Excellent, and very informative. Well done.

[@enrique5252]

[@stevennope5139]

great video! learned so much with this. I have one question though, is there a way to make a mold having multiple masters in it so that I can cast 2 or more castings in one batch instead of having to waste time and silicone on 2 separate molds? I was thinking multiple funnels/runners that leads resin from one area to another, do you guys have a video on this?

[@ShawnaCostonPhD]

Nice video...Thanks.

[@artsculpture1024]

I am practicing with molds. One part molds are simple ad easy, it's the more complicated sculpts and small hands that are challenging.

[@catmechanic1261]

Bravo
