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.

@vasyapupken 2 жыл бұрын
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 )
@davefloyd9443 Жыл бұрын
Can you explain that a bit more please? Are you saying to build the box on glass bottom sheet?
@EricStrebel Жыл бұрын
I believe what he is saying that the top of the mold just needs to be flat so that you can put some release agent on a piece of glass and when you pour your part, Just slap the glass on top of it so that it comes out flat once it's cured.

@@EricStrebel Hi Eric! Thanks. I mold little flat bottom fishing baits in an open topped mold (bottom of mold case). I've been gluing the flat side of the master to pieces of smooth, plastic laminated shelf and building the box up from there. Just cant get a flush "top" because silicone leaks up to the glue line, causing thin flashing. Looking for a cleaner finish really.
@EricStrebel Жыл бұрын
That's why I make all my molds as two part molds, and almost never as open face mold because you can't control that top surface when it's an open face. Simple as that.

@@EricStrebel Yep I've been coming to that conclusion myself after watching your channel. Trouble I have with that is that when laid flat some of the fish and worm masters are less than 10mm high, making for very thin molds. They are sort of fat ballpen sized. Should I look at molding these vertically?

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?

What is the brand of the white pigment that you use? I've been researching for a good opaque white that doesn't have major issues with the resin curing. I'm trying to compile a list of some to try. Does it take a lot of pigment to get a good opaqueness? Or does a little go a long way?

can you have a video where you explain more about the key seals in the silicon? Is it to hold the silicon mold in place?

This video is where i first see this method so i would like to find out more. Or where can i read more about it? Thank you

Made it up actually, all the other methods you mention are pre laser. You need a laser or a way to make a digital key for this to work. Yes the key seal hold the two halfs together. Almost every video in the last 2 years of mine used this technique in some way shape or form

Man Eric, your detail of mold production is amazing. got some very nice epoxy s here in Europe, some very liquid. Some long cure times. But I got the inverse experience, the urethanes smell like .... For days and the epoxy is almost totally odourless. Of course use a VOC meter to know what the air quality is. maybe I can send you the websites, they even have extra uv stabilizers that you can add. Iff I have some time I will even make a video of it. And send it to you. Greetings from Belgium

Curious if you know whether you can use urethanes for things like kitchen utensils (things that will touch food or drink). The Google machine is failing me on this. I understand why folks (esp manufacturers) might be shy about making claims. It's probably ridiculously expensive to have things validated at FDA and even then, errors in end use can make it a huge liability for them. I see that some epoxy resins that use BPA have been FDA-approved for some food contact. Anyway, I would appreciate your expert input on this question. I have not really worked with anything but silicone, and even then only a few times.
