13 best mold material for casting resin

Mold materials for casting resin are essential components in the resin casting process, particularly in crafts, jewelry making, and various arts and crafts projects. These materials are used to create molds into which liquid resin is poured, allowing it to take on the shape and detail of the mold. Here are some common mold materials used in resin casting:

  1. Silicone: Silicone molds are perhaps the most popular choice for resin casting. They are flexible, durable, and can capture intricate details. Silicone molds are reusable, making them a cost-effective option for both beginners and experienced crafters. They come in various shapes and sizes to accommodate different project needs.

  2. Latex: Latex rubber molds are another option for resin casting. They are flexible and can also capture fine details. However, they tend to have a shorter lifespan compared to silicone molds and may require more care to prevent deterioration over time. Latex molds are often used for larger-scale casting projects.

  3. Plastic: Plastic molds are often pre-made and come in a wide range of shapes and designs. They are suitable for simple resin casting projects but may not be as versatile as silicone or latex molds when it comes to intricate designs. Plastic molds are generally affordable and disposable.

  4. Wood: Wooden molds are less common but can be used for certain resin casting applications. They are typically used for custom or one-of-a-kind projects where other mold materials may not be suitable. Wood molds are usually not as flexible as silicone or latex, so demolding may require more care.

  5. Metal: Metal molds, such as aluminum or stainless steel, are used for specific resin casting applications, particularly in the production of high-quality jewelry and metal-infused resin creations. These molds are durable and can withstand high temperatures required for some resin types.

  6. Glass: Glass molds are primarily used for casting clear or translucent resin, as they provide a smooth and glossy finish. They are often used in making resin jewelry or decorative items. Glass molds should be well-greased to facilitate demolding.

  7. Flexible Resin Sheets: In some cases, crafters create their own molds using flexible resin sheets. These sheets can be shaped and customized to create unique molds for resin casting. They are especially useful for irregular or custom shapes.

When selecting a mold material for resin casting, consider factors such as the complexity of your design, the level of detail required, the size of your project, and your budget.Silicone molds are generally a versatile and popular choice due to their durability and ease of use, but the specific mold material you choose should align with your project's requirements and your crafting preferences.

  • It is food grand and FDA compliant
  • It requires no equipment, cups or stir sticks
  • Easy to use by hand mixing 2 equal amounts of the yellow and white putty and cures within 20 minutes that gives users a flexible rubber mold with exact detail

User questions & answers

Question: how does it work
Answer: It's as easy as the instructions on the bottles...mix equal parts of the putty together, just like Play-Doh, and until you see that the two have no more streaks but it is one color. Then simply apply it and press the mixed putty on to your mold. In a matter of a few minutes you have your reusable mold hardened! What I like about this one is that it is food safe, excellent for lolly pops, ice cream, etc. Hope that helps you.
Question: If you can use this for food, what is the highest temperature
Answer: I have never used it for food but I have made charms with a high heat glue gun and they have survived. The highest I have baked anything in it has been 275 degrees. I don't know if boiled sugar or syrup will be too hot.
Question: Does this make a flexible mold like rubber/silicone
Answer: Yes it is, I believe it is a silicone. I've made lollipop molds and had no trouble bending them to retrieve the lollipop.
Question: is this product reusable
Answer: I am not sure exactly what you mean by "reusable" so I am answering this two ways. You can use a mold you make over and over again, I have not had one wear out yet. You cannot create another mold from one that you already made since the product hardens to form the shape you are wanting to duplicate. So once you create a mold it is not changing in my experience.It's a wonderful product and I use it quite often. You won't go wrong.

User questions & answers

Question: How pliable is it before it sets? I want to make a mold of my dog's paw print but I don't want to have push hard on her paw to get the imprint
Answer: It's been several months since I've used it but it seems like it was about as pliable as playdough (sp?).
Question: Can I use it to make a dental in-print
Answer: It is not approved for FDA-type applications like food contact or internal use.
Question: how do you de-mold it
Answer: Use some type of mold release. I use petroleum jelly thinned down to a liquid with paint thinner. Paint on with small paint brush. When it dries, there will be thin film of the vaseline which will allow casting to be removed from mold.
Question: I need a sample to replicate crown molding that is attached to the wall. Would this be recommend for that vertical application
Answer: Yes, it is stiff enough to stay in place, even in your vertical application.

User questions & answers

Question: What is the ratio for the two parts ?, the white and the catalyst ,do i use less of the catalyst? Or even ?, could u give me an example
Answer: this is a 10 to 1 mix ratio by weight. for example if you need a 50 gram mold made you would mix 50 grams of base to 5 grams of activator. you always want to mix a little more than needed due to losses in and on the sides of the mixing container.
Question: Will this stain or discolor raw wood
Answer: No, but will get down into the pores and will troublesome to remove the rubber from the wood. If the wood was treated and smoothed out, it will go well. Wood like driftwood with lots of pores and bores will most likely absorb the silicone in places that will prove to be harder to remove. You can use a knife but you'll have silicone buried in those pores making the wood looked like a 5 year old smeared green playdough all over it.
Question: I ran out of material 1/2 way through making a mold. Can I come back 2 days later and add more
Answer: yes this rtv silicone mold rubber will adhere perfectly to itself.
Question: I want to make a silicone cup that is flexible, is this stuff capable
Answer: This stuff would work with the right mold, however, I'm not sure it's really food safe. That's mighty important if you're ever going to use it to drink with. I was using it for Jewelry stuff so I didn't need to worry about that part. There's a lot of silicone cups that hikers use. I'd search that out if you only want to make for you. if you're wanting to go into production, contact the company itself. That's the only safe way. Good luck whichever way to go.

User questions & answers

Question: How many ounces is each bottle
Answer: It is sold and labeled in Lbs.Part A is 1.2lbs and Part B is 1.6lbs and I can't find any label that provides info regarding ounces. The dimensions are almost the same size as a 16 oz bottle so it's close to 16oz per bottle but that it an estimate. Sorry I can't provide more info.
Question: Is it enough liquid to make a 12" vinyl record mold
Answer: Probably two orders of this would do that. Depends how thick you want your mold. When making molds always get more than you think you need. If you're pouring the mold and you run out then the mold is incomplete and useless. I don't know where you live but ordering directly from smoothon is usually faster. They have facilities in Texas and Pennsylvania. You can't beat their products.
Question: is this heat resistant
Answer: Not positive but aren't all silicones heat resistant. Great product.
Question: How large of a mold will this usually make? One large one? a few small ones? or is there a specified size reccommended
Answer: I molded an object with a volume of 37 ounces but it took a set and 1/4 of another set of these bottles. Safe bet that if you have a model with a displacement greater than the one I did, you need two sets. Some find the simplest way is to pour rice around your model then pour the rice into measuring cups to get a better idea of how much. The hollow mold that I made was about 11.5 inches high and 4 inches in diameter with a width of 1 inch on the sides and bottom of the mold. So.. to encapsulate a volume of 37 ounces with enough material so that the mold was free standing it was a set and 1/4 of silicone at the least. My mold did not have a top though, with a top, it would have been a set and a half, no question about it.

User questions & answers

Question: Can I put a picture in these for a gift
Answer: Yes, there are tips on Pinterest and YouTube for the type of paper and preparation of the photo. Makes an awesome gift.
Question: I have never used molds. How do I get the bubbles out? I now use a torch or a heat gun
Answer: I recommend lightly spaying mold release in the molds and shake dry. Bubbles can be an issue at times. I mix gently the resin and catalyst with a popsicle stick to try to avoid bubbles. I haven’t tried the heat aspect yet, but i might try it next time I cast something. Hope this helps!
Question: can i put these in a pressure pot
Answer: I think the person is asking whether they can be put in an epoxy curing pressure pot, not a pressure cooker. Two different things. Epoxy curing pots aren't heated up. (BTW, avoid using a *vacuum* pot, that results in a foamy mess.) An epoxy pressure pot compresses all gases in the epoxy to below visible size. Yes, silicone molds will withstand typical epoxy pressure pots pressure of 50-70 psi with no problem.
Question: what is the usage of the cooper wire
Answer: you can use it in the orgone pyramid making
