Complete Guide To Silicone Molds

The Complete Guide to Silicone Mold Making and How You Can Use It For Your Own Projects

Introduction: What is Silicone Mold Making?

Silicone molds are used by companies and artists in a variety of industries to produce products that are made from various materials.

Silicone molds are used in the production of many different products, such as epoxy resin, candle making, toys, and automotive parts. They can be made of different types of silicone depending on the application.

There are two main types of silicone molds: positive and negative. A positive mold is one that has a cavity which will be filled with liquid silicone to create the final product. A negative mold is one that has a shape that will be filled with liquid silicone to create the final product.

Types of Silicone for Mold Making

Tin Cured and Platinum Cured

The main difference between tin-cure and platinum-cure silicone mold making rubbers is in the metal used to catalyze or cure the base silicone. Tin-cure rubber relies on traces of tin, while platinum-cure rubbers are based solely on platinum. As a result, tin-cure silicone rubbers usually cost less than platinum-cure ones.

Performance Differences between the 2 silicone types:

INHIBITORS

Mold-making rubbers can be inhibited from curing by contaminants on surfaces. If you’re using a modeling clay that contains sulfur (typically older types), the rubber may become sensitive and easily damaged. Platinum-cure silicone rubbers have a critical sensitivity to sulfur. If they are exposed to it, they will not cure at all. Tin cure silicones can cure over models containing sulfur as long as the surface is thoroughly sealed with an acrylic spray.

SHRINKAGE

A major difference between these two systems is the shrinkage of cured rubber over a period of time – short term vs. long term. The long-term shrinkage is typically measured in percentages of the original thickness, but it can also be given as a percentage of the amount for which the rubber has been stretched. In short term tests, shrinkage was found to be only about 10% after two years; this would mean that at two years, a given sample of rubber would be 50% thinner Tin-cure silicone rubber molds generally exhibit higher shrinkage over time depending on the type of mold rubber being used, material being cast into the rubber mold, mold configuration, and other variables.

Mold Release Agents for Silicone Molds

Silicone-to-silicone applications such as making two-part molds or casting silicone into silicone are possible, but require a release agent. This release agent cannot contain a significant amount of silicone oil. Here are some release options:

  • Mann Ease Release™ 200 is formulated specifically for releasing silicone rubber from silicone and other surfaces. Applied as a light mist coat, it will not interfere with surface detail.

  • A mixture of 2 parts isopropyl alcohol and 1 part dish soap can be used in some cases to release silicone from silicone.

  • Petroleum jelly can be used to release silicone from silicone, but it should be thinned with mineral spirits so that it can be applied in a thin layer with minimal visible brush strokes.

If you’re trying a new silicone recipe and want to be sure that your release agent will work, we recommend testing it at a smaller scale.

Silicone Mold Design Process

Silicone mold design process is a process of making a rubber mold from an object.

The first step is to create the silicone mold design. This can be done by using a CAD program or by using an object that you already have available.

Next, you need to create the silicone mold container. This should be a little bigger than the object to be cast. A simple method is to use foam board to create the container. For added ease of releasing the final product, you can coat the inner surfaces with Tyvek (available at the post office as waterproof mailing envelopes. Use hot glue to assemble your box.

Next, you will need to place your object to be cast into your container. You will need to lift it off the bottom of the container. In my example, I used hot glue sticks to lift the object off the bottom of the container. These will also be my pour holes to fill the mold.

Pour the silicone over the object in your container. Wait 24 hours, and remove from the container.

Removing the Object From the Mold

Once the silicone has cured, and the mold removed from the container, you will need to remove the object from the center of the mold. There are many great YouTube videos dealing with this topic. Here’s one that shows how to remove your object effectively. 

Once removed, you are ready to cast your piece using your new mold! Mix Puduo Resin and pour into the mold. Wait 10 hours and enjoy your custom piece.

Conclusion & Resources

Creating a mold is not as hard as it sounds. All it takes is a vision and a little work. As a beginner in mold creation, I was pleasantly surprised at how easy it was to create the mold. I used Translucent Platinum RTV-2 Liquid Silicone Rubber. Available HERE.

Puduo Anti-Yellowing Formula Has Arrived!







3X Anti-Yellowing Puduo Epoxy Resin

Puduo Anti-Yellowing Epoxy Resin is a new product on the market that has been gaining popularity among DIY enthusiasts. It is a two-component epoxy resin that comes in a 1:1 ratio and can be mixed easily. The UV resistance of this epoxy resin makes it perfect for outdoor projects. Puduo Epoxy Resin is known for its easy to use formula, casting, and crafting properties. When mixed together, the two components form a clear liquid which can be used with silicone molds, live edge river tables, suncatchers, jewelry, home décor, and much more.

To mix Puduo Anti-Yellowing Epoxy Resin you will need:

Puduo Anti-Yellowing Part A – This is the Resin

Puduo Anti-Yellowing Part B – This is the hardener

Gloves – Your choice of material, just protect your hands.

Mixing Sticks (Included) – Take care of these silicone sticks by wiping them with a paper towel when done.

Mixing Cups (Included) – The included cups measure 100 ML max. For larger cups, please click here

Pigments (optional) – Choice of pigments can include: Glow in the dark, resin tint, resin dye, resin paste, glitter, or any other item you want to use that is completely dry. Water/moisture is not recommended and can ruin your project

Silicone Mold (Optional)For more molds, please click here

Mixing Puduo Resin Like A Pro:

1) Measure the amounts equally using a 1:1 ratio. For example 40 ml of part a to 40 ml of part b. Note: I do not recommend trying to mix smaller than 80 ml total. This is because it makes it too easy to get the measurements just a little bit off.

2) Mix thoroughly. This does not mean to only mix for 3 minutes and call it good. This means to mix the product until it is perfectly clear. Make sure that you get the sides on the bottom of the cup really well.

3) Pour your mixture into another cup. Get as much of the product out of the cup as you can. Then mix the new mixture again. Mix it for approximately a minute.

4) Split the mixture into as many cups as you have pigments. For instance, if you are only using red, black, and clear, split it into three cups. Mix the pigments in well. Then let the product set for approximately 15 minutes to release all of the bubbles and begin its exothermic reaction.

*The mixing instructions are the same for all Puduo Epoxy products.

I created suncatchers using this new formula and I will be hanging them in our shop. We live in Arizona, so the sun here will definitely be a great test! We will do an update video in 30 days.




Flower Drying and Use in Puduo Epoxy Resin

Using Dried Flowers With Puduo Resin

Using dried flowers is simple and can be a lot of fun! Dried flowers can be purchased through sites like Amazon, at hobby stores like Michaels or Hobby Lobby, or you can pick and dry your own. As we live in the desert, and the spring flowers are in bloom, we decided to go pick some flowers, dry them, then create something beautiful on a Live Stream. This is the same technique you would use for fresh roses, fruit, or anything else that has moisture.

Moisture is the enemy of epoxy resin. It can cause fogging, uneven cure, and general chaos in the product. If you epoxy something that contains moisture, it can rot inside the piece. That’s why it’s vital to remove all moisture.

You can remove moisture a number of ways. The sun, a dehydrator, Silica Gel, a book, or anything that will suck the moisture out quickly.

  1. Sun – You can dry some items in the sun. Depending on how fragile the item is will determine if this method is right for your project.
  2. Dehydrators come in a variety of sizes and prices. Here are 2 that you can purchase from Amazon. I have not tested these products, so be sure to read about their proper use. 
    1. This is a lower cost option:
    2. This one is the more expensive version:
  3. Book – You can use a thick book to press and dry your flowers. Use copy paper between the pages so the flowers wont stick to the pages.

For this project you will need:

  1. Fresh flowers – These can be hand picked, or purchased from a store.
  2. Silica Gel – This can be purchased from Amazon.
  3. Container with a lid. Here’s an example from Amazon.
  4. Puduo ResinAvailable here
  5. Silicone mold of your choice – Here are some Amazon Selections

Follow these steps:

  1. Pour silica gel into your container. 1/4 to 1/2 of the way is good.
  2. Place your fresh flowers on the silica gel. Close the lid on the container.
  3. Wait until the flowers are dry. Drying time will vary depending on the amount of moisture in the flower. Expect between 2-10 days.
  4. Once fully dried, insert your flowers into the mold, mix your Puduo Resin, and fill your mold. Wait 8-12 hours before demolding. Set on a flat surface for at least 12 hours after demolding to finish your curing process.

Mask Your Puduo Resin Project With Latex For Unique Effects

Easy Technique To Create Unique Effects

Using latex, you can easily mask off any area you wish, to create dramatic effects with Puduo Resin. In this live stream from Facebook, co-founder of the US Support Team @Sacred7Senses takes you through the steps required to create this selenite moon pyramid. This blog has a companion video included below.

Using a 5.9 inch pyramid mold from Amazon, Ashley first poured about an inch of liquid latex in the tip and let it cure (About 8 hours). She then poured Just enough to leave a small portion exposed for the resin to bond to, and let cure overnight.

After the latex cured, Ashley mixed up some Puduo Resin and poured the first of 4 layers. In this layer she added some soap clouds. Soap clouds can be made easily by putting bar soap chunks in the microwave! Amazingly easy technique!

Each additional layer of Puduo Resin was used to add glitter and pigments to the mixture to achieve her desired results. Watch the full video below!

Turn a Dollar Tree Tray into $50

We all go through it. We make something that we think is spectacular only to have it sit in inventory for a long time. As artists, we need to be able to sell our creations in order to continue our art journey. I have used many of the molds you find on Amazon. I happen to be lucky enough to have a shop where I can put my pieces, for as long as I want, and sell them. This enables me to see what sells best. 

This tray has been one of our best sellers for a couple of years at our shop. Typically people want them for unique rolling trays or dab trays, but that’s because that is how I design and market them. These trays are cheap to get, easy to make, and easy to sell. The ease of sale is directly related to how the tray looks. So make sure your design elements look good together. Feel free to copy me exactly to get a hang of it. I would love to see your version of this tray! 

For this project, I have:

1) 2 metal Dollar Tree trays 

 

2) Puduo Resin

 

3) Glow Pigment

 

4) UV Reactive Pigment

 

5) Hand picked and pressed flowers

6) Stickers

7) Rose Quartz barrels and Quartz Points

8) UV Light – This can be sunlight, UV Flashlight, or UV Laser

Available in our shop now!

This project uses 220 ml per pour. Each tray gets approximately 100 ml each per layer. Each tray takes 2 layers, although you can add more if your design calls for it.

This project was streamed live on Instagram and Facebook. If you would like to see the original recording. We have live streams every Tuesday and Thursday nights. Catch our latest, or catch up on previous episodes on Instagram or Facebook.

The first coat is your base coat. It will contain your glow, UV, or whatever pigments you decide to use. I find that people are really attracted to the glow trays. With four different colors of glow, the possibilities are endless!

The second coat is your flood coat. Please be sure to read our special blog on mixing Puduo. There is important information on mixing this to get professional results!

By using different components to your tray, you can turn it into a ring tray, jewelry tray, or just a decorative tray. On these dab trays, I put a glass spoon for the wax and crystals to hold the pipe when done.

If you would like the UV Flashlight or any of the crystal products featured in this blog, you can contact me through messenger.

Big Letter Lamp Pour

Have you seen the big letter molds? How about a big letter mold lamp? Well, over the past week, I have been creating a big letter “A” lamp.

I wanted to do this project to show how easy it is to use Puduo Resin on a deep pour. This pour was done in 3 layers on Instagram, Facebook Live, and a complete run through on YouTube. The original, full videos can be found on Instagram and Facebook

Doing a deep pour with a casting resin is a delicate dance. You want to pour the least number of layers without having a flash cure. Flash cures occur when the chemical reaction creates so much heat that it cures in minutes. The result is that the epoxy contracts so fast that it can’t remain level. Therefore, it pulls away typically at the corners. You may also notice a blocky look on the surface as parts cured a little quicker.

With Puduo, you can typically pour 200 ml without having a flash cure. This is in a room between 70-80 F. Using this formula will allow you to pour the least number of layers. 

This mold came to us from MoldyFunUSA.com.   We were asked to try this product and supplied a sample of their product. We were very happy with this mold. You can find the complete set of alphabet molds here. You will receive a discount upon clicking this link.

alphabet Pouring this mold is easy. There are no complex designs to trap air bubbles, and the amount of space in the mold makes it an easy pour to decorate. Use flowers, lights, or whatever else you want to use to decorate this lamp.

This letter “A” mold is 1.5″ H x 6″ x 6″ at the widest. This is a large mold and requires approximately 500 ml. Puduo 32 oz kit contains 946 ml. 473 ml of part A, and 473 ml of part B. 

Ensure proper mixing techniques when using this product:

1) Measure the amounts equally using a 1:1 ratio. For example 40 ml of part a to 40 ml of part b. Note: I do not recommend trying to mix smaller than 80 ml total. This is because it makes it too easy to get the measurements just a little bit off.
 
2) Mix thoroughly. This does not mean to only mix for 3 minutes and call it good. This means to mix the product until it is perfectly clear. Make sure that you get the sides on the bottom of the cup really well.
 
3) Pour your mixture into another cup. Get as much of the product out of the cup as you can. Then mix the new mixture again. Mix it for approximately a minute.
 
4) Split the mixture into as many cups as you have pigments. For instance, if you are only using red, black, and clear, split it into three cups. Mix the pigments in well. Then let the product set for approximately 15 minutes to release all of the bubbles and begin its exothermic reaction.
