Silicone molds have become the go option for making resin artwork. Silicone’s durability and flexibility have allowed beginners to experiment and make tryout their first resin creation process. There are many silicone molds out there that can be bought and used to make the desired end product.
For those who are adventitious and want to test their creative skills. You do have the opportunity to make your very own silicone mold. You may want to make a replica of your favorite childhood toy or souvenir.
Making your silicone molds requires you to have a master pattern that is nonporous and doesn’t react to silicone. The master pattern must also fit in the container where the silicone liquid will be poured to produce the mold.
In the article below, I will go into depth on the tools you need before creating your own silicone mold.
How to Make My Silicone Molds
A mold is a cavity that can be used to replace another object. The original object used to manufacture several other of its kind is referred to as the master pattern. The object can be a plastic toy, jewelry, or Christmas ornament.
The correct master pattern is needed to make the precise silicone mold. Not all master patterns can be used in creating silicone mold. Ensure that the master pattern will withstand the mold-making process.
For a DIY project, you can purchase a vintage lambs stand and cast the lampstand to create an indoor resin lamp. Once you have your object, you can start making our silicone mold.
Other main components needed in the process of creating a silicone mold include.
Liquid Silicone: Liquid silicone is a two-part polymer joined by a chemical bond. The reaction is referred to as progression when the polymer is injected and molded.
This progression created the structure’s permanent strength and shape when fully cured. A commonly used silicone liquid is the Smooth-On OOMOO 30
Mold Release: The release agent plays a significant role in creating silicone molds. The agent helps in the removal of the master pattern from the mold. This prevents the mold from having severe defects and makes it easier to remove the master pattern.
The container or Mold Box: The Master is placed in the container, and the silicone mold is poured into. This container needs to be larger than the master pattern.
The container is the first item to be considered when you are ready to start making your own silicone mold. The container can be made from a simple plastic container. The container needs to be nonporous with a flat bottom. Ensure the container is clean and free from debris.
Lay out the master pattern in the container. The master pattern needs to be layered out flat in the container. For one-sided master patterns, the detailed parts need to be sided upwards.
Begin with spraying a light misty of the release agent, mold release. The mist must cover the entire space that the silicone liquid occupies. After applying the release agent, allow the mist to dry for 10 minutes.
As you let the release agent dry, start mixing the silicone solution per the manufacturer’s instructions. Thoroughly mix the solution to remove any air bubbles.
Depending on the size and quantity of the mixing solution, the solution can be mixed by hand or using an electric mixer.
Pour the silicone liquid gently. The goal is to start filling the bottom of the container first and gradually covering the master pattern. Ensure that the master pattern is fully covered. The curing might take 1hr to 24 hrs, depending on the silicone liquid used.
The moment of truth during the de-mold phase is when the mold is ready to be extracted from the master pattern. When done correctly, the mold can cast resin statues and figurines. Before pouring the resin on your first resin casting creation process, ensure you spray the release agent.
Pros of Silicone Molds.
Ease of use. Compared to other materials like plastic. Silicone is flexible to work with. This is very useful when removing the casted parts without damaging the mold. Silicone can cast objects from simple to intricately detailed artifacts.
Durability: Silicone molds can be used several times. Depending on the number of uses, the more times the mold has been used, the likelihood of its degradation. We encourage cleaning and having mold dry thoroughly to increase the mold’s lifespan.
Versatility: Silicone molds can be used to make artisanal items like figurines, plastic jewelry, and candles. The ability to mold almost everything at home is why we recommend using silicone as your go-to mold. Compared to metal mold or wood mold. Silicone molds are relatively easier to make.
Heat Tolerant: Silicone molds can tolerate both hot and cold temperatures. The molds can be stored without degrading or warping. Avoid stacking the molds if you have different molds stored up. Stacking will compress the molds causing the loss of shape and detail.
Cons of Silicone Molds.
Although flexible, when taken too far, silicone molds are known to tear; when stretched beyond structural limits, silicone molds are known to break.
Silicone has a high-temperature limit compared to plastic. Silicone can handle temperatures up to 250 degrees Celsius. Silicone will deform, losing its flexibility and becoming brittle.
Making silicone molds can be a great activity at home as the opportunity to make resin art pieces for your home and garden. You don’t have to have shop or factory tools to make your silicone molds. The easy-to-follow steps above can be applied to meet your heart’s desires.
With multiple attempts at making your silicone molds, you’ll learn how to perfect your mold creation process and end up with the molds that suit your style and taste.
