Epoxy vs Urethane Casting Resin

great as always! I've done mold work for a while but always learns something new from you.

Eric, Really good production values - camera work, voiceover, detail shots, discriprion, and of course, your the content is spot on! ⭐⭐⭐⭐⭐

vids just keep getting better

Great comparison video! I haven’t seen you post anything for a while and was getting concerned. But glad to to see you post. I’ll be sending you a project to quote for me. Thanks!

Undercut to lock the parts together was so smart!

Found you today. I love your ideas!

I make almost all my molds using that plastic cup open face method. Works really well for small pieces. Any issues I've had were related either to materials mismatch or improper mixing.

Really impressive and answered my questions about resin vs. epoxy. New to this stuff so this is very helpful. Thx Eric - SUBSCRIBED

this stuff are great! Keep it going!

Great video. Super informative. Can't wait for Smell-O-Vision comes to YouTube. Mahalo for sharing! : )

I do a lot of open face molds I make using machinable wax and a cnc , I set a flat piece on top after the pour that has a small hole to allow the resin to escape as the flat

Great video! thanks for posting it! Could you maybe go over in more detail how the small part of the mold for the locking tab functions? Thanks again!

Good content, great video, seeing the comments leads me to believe that a post about where to source the products would be helpful.

Hey bud, I enjoy your videos, I do production pour casting for a family owned urethane business in NE PA. When we have an open top mold, I just fill it it a little over and either scrape a Ross the top with a good putty knife/drywall tool or use a block of steel/aluminum and slide it across the top of the part. It works very well. You just have to use a smooth continously motion. What you are left with is just regular flash. For some molds we even cast in guide rails for the purpose of the final sliding piece. It is occasionally possible to get a bubble with the slide top method, but a quick dremel of the surface and a dab of material after initial demoldis all it takes to fix it. Good luck and ty for the content as it is also something I do as a hobby. P.s. is it strange that when I'm off work I'm spending any amount of spare time watching you do the same/similar thing haha.

you can control free surface of a one part mold quite easily. just cover it with glass or any flat piece with release agent on it. this requires only slight change in the mold itself - mold bottom (top) needs to be flat as well so no plastic cups )

very nice work

I think you and Robert Tolone would have some great discussions with each other an reviews of each others videos and techniques.

Hi Eric, I'm always amazed by your solutions to the 'tricky bits' of mold making, e.g. the separate mold part for the delicate clip/prong part. My 'stupid' question (i'm a very small time, part maker with 0 budget) is, do you dispose of the syringes after one use or can they be cleaned of the resin? ..and if so, how?

thank u

I think you should get a fume hood for any noxious chemicals in your shop.
