    I don't know why this wasn't included in the video, but when you make the mold, glue (or otherwise attach) a conical piece to the top of the master. This way the mold will naturally have a funnel included to pour the resin in. In terms of resin leaking out of the sides, I would put the two pieces of the mold together, tape the sides for extra protection, and sandwich the mold between two pieces of wood and put rubber bands or clamps on it. This way the mold does not deform by the pressure of whatever is holding it together. Pour the resin in slowly, tap it against the table a couple times to dislodge any air pockets that might form, and top off. I've seen dozens of comments below asking these questions, and I don't know why they haven't been answered yet. Hope this helps.

      @@ErikNonIdle i caught the same lol, maybe a short dowel or something could be used.. but also, even with that, this mold would be sitting in the wrong orientation. it should be upright, and at that point it probably wouldn't stand.

    • @fledgeking
      @fledgeking Рік тому +2

      You have to make a pour spout (usually cork-shaped) that will be attached to the master and then pour the silicone around it, it will give you a reference point on your new mold and a spout to pour your casting material into. Some molds will also have air spouts, which are thinner and help prevent bubbling. (AKA he needed to stick some rubber in there somewhere and failed to do so presumably)

    I want to make a mold of a foam item. Can you use silicone with foam?

    • @AlumiliteCorporation
      @AlumiliteCorporation  3 місяці тому

      Yes, you can use silicone to make a mold of a foam item!
      However, here are a few tips to get the best results:
      Use a release agent: Foam can sometimes stick to silicone, so using a mold release like UMR Mold Release will make it easier to remove the foam without damaging it.
      Apply the silicone carefully: Brush on a thin layer first to make sure the silicone fills any small details, then pour the rest of the silicone to cover the foam. This prevents air bubbles that can distort fine textures.
      Consider the foam type: Some foams, especially very porous ones, may absorb silicone if not sealed first. You can seal the foam with a thin layer of spray varnish or resin before pouring the silicone.

  • @flyyynt
    @flyyynt 2 місяці тому

    Actually, this part because it has a flat bottom could be molded without the clay by taping off the inner side of the opening and gluing the master with top facing up to foam core. Make the box walls the same and pour the silicone. When cured separate it from the bottom foam core, turn the box over, remove the tape, and push the silicone with the master deeper into it so you can pour silicone for the other side. Do that the same as in the vid.
    To make the casting, pour a little resin into the top half and "squish" the bottom half onto it. This forces the resin to fill the mold and the excess gets squeezed out the sides. It's messy but it works. Or you could mold in or cut a pouring/vent hole(s).

  • @asrock49

    I bought monster clay based on this video (soft version). After experimenting with it and pouring silicone on it multiple times, I realised monster clay is bullsh*t. It has never come off cleanly as it does in the video. To be fair, I was trying to mold a very small intricate part (alot smaller than the video). But it always held the part in place rather than the silicone. Orientation is vital to my part, so bieng held by the clay and not sticking to the clay is pivotal. Anyhow, I don't want to write a diatribe. If you have any questions about this, reply to this comment.

      Hey there! 😄 It sounds like you’re working on a cool project with some rose flake in a 3mm-high square, but the finish isn’t quite what you had in mind. No worries-you can fix it up and get the smooth, polished look you want. Here’s a quick guide to sanding and polishing your piece without damaging it. 👍
      What You’ll Need:
      Sandpaper in various grits
      Water for wet sanding (to avoid overheating and scratches)
      Polishing compound (optional, for a high-gloss finish)
      A soft cloth or polishing pad
      Step-by-Step Sanding Process:
      Start with Lower Grits:
      Begin with 400 grit sandpaper to remove any uneven surfaces or imperfections. Since your piece is small, be gentle to avoid sanding too much off.
      Gradually Work Your Way Up:
      Move through finer grits step-by-step:
      600 grit
      800 grit
      1000 grit
      1500 grit
      For a super smooth finish, you can go up to 2000 grit or higher. Always wet-sand to keep the resin cool and reduce scratches.
      Polish It Up:
      After sanding, use a polishing compound to bring back the shine. Apply it with a soft cloth or a buffing wheel for the best results. This will give the resin a smooth, glass-like finish.
      Pro Tip:
      If you’re still not happy with the look after polishing, you can always apply a thin topcoat of resin to even everything out. Just make sure the surface is clean and sanded lightly with 600-800 grit before pouring to help it adhere properly.
      Let me know how it goes, mate, or if you’ve got more questions!
      🛠 Peace and happy crafting! ✌

    So I'm clear, it looked like when you were pushing your master into the wet clay substrate, you didn't have to worry about it sinking. Is it really that simple? I don't have to wait for it to cool to a certain viscosity or anything, do I?

    Coworker shared this with me as I do some mold-making in our shop. My feedback below. I hope I don't sound too egotistical! I think these are great tips, and every part has unique requirements/challenges:
    I learned a few tips from that...
    I have microwaved clay to make a base before, and yes it is quick and easy, but the "going off to get a snack" portion can trip me up, because I'll come back to it being already too hard. It also only works on parts that have a flat split line (which is often not the case), and doesn't cover situations like pass-throughs, die locks, severe undercuts etc. That said, it might be worth trying more often just to initially establish the part in the mold, and then I can do all that other stuff (including the non-flat split line) manually. It does also require a good bit more clay to do a pour - you can't leave any voids, so you'd better have enough.
    I tend to prefer the cardboard boxes over legos just because I can make them exactly the right dimensions, and I think assembly would probably be pretty similar time-wise, but I guess legos could get pretty close. Legos may release cleaner, but they also won't split at the corners and fold down...on the other hand, they will be perfectly square, and exactly the same dimensions when flipping the mold over (the cardboard mold boxes can get destroyed or be slightly off from perpendicular), so they seem like they'd be worth trying for that reason alone.
    I also like the way his clay cutting tool makes grooves. The rounded profile achieves the same air release as the circular dents I make with the head of an acorn nut, but the continuous line probably helps seal up leaks better, so I actually like that.
    I also very much approve of taping around molds - it'll slow any accidental leaks, and it just helps hold the mold together.
    A couple of things he could have maybe done better (or maybe he did do but didn't show, for sake of simplicity/simplest case):
    -Degassing
    -Casting under pressure to eliminate any bubbles trapped at high points (probably wasn't necessary on this piece but still - rarely hurts)
    -Spray-on mold-release is easier/faster to apply and less likely to miss a spot, although you do want to brush it in and re-coat
    -Use different dye colors for the silicone halves, to ensure proper mixing, but also to clearly see the separate halves and if anything bonded to one or the other
    -He also didn't show the process of adding sprues or vents; I personally like to hot-glue my sprues on before pouring the top half of the mold, then add vents and reservoir bowl with a sharp syringe and razor knife, respectively.
