Technical Properties

The silicone mold making process is as follows:

• Obtain or make the master pattern: The master is a positive original of the parts you will make with the silicone mold. This can be an existing solid object or a new item made with manufacturing equipment. (See next section.) For best results, the master should not contain complex cavities or overhangs.
• Lay the pattern(s) in the container: In many cases, a container is made specifically for the pattern. The box container can be made from e.g. wood or cardboard. After applying mold release to the inside of the container, place the patterns flat side down in the container or suspend them within the newly made container. If you have multiple patterns (for making a popsicle tray, for example), spread them out evenly. Spray them with mold release. If you are making a two-part mold, half of the container should be filled with clay and the patterns inserted half-way into the clay.
• Mix and pour the silicone: Mix the two silicone components according to the instructions on the bottle, then pour it slowly into the container. The surface level should rise half an in inch above the top of the master pattern to prevent the mold from tearing. Curing can take several hours (specific times may be specified on the silicone bottle). For professional applications at 3ERP, we remove air bubbles, then cure the silicone mold in an oven at a medium temperature.
• Remove the cured mold: Once it has fully cured, the silicone mold can be gently removed from the container. If you are making a two-part mold, you should remove the clay, leaving just the mold with the pattern still half sticking out. Return the mold to the container the other way up, so the pattern is protruding upwards. Apply mold release to the mold and pattern, then fill the other half of the container with silicone like in Step 3, wait for curing, then remove.
• Remove the master pattern from the mold: Gently remove the master pattern(s) from the silicone mold. If you are making a two-part mold, you will first have to separate the two halves of the mold.
• Cast the parts: Depending on your casting material, casting your parts may be as simple as applying for mold release then pouring liquid into the mold. Professional processes like vacuum casting involve inserting the silicone mold into a machine that removes air bubbles from the casting material.

Special containers are available are on request.
