March 2023 | ahson raza

Working with silicone RTV rubber in mold making can be a challenging task, especially for those new to the process. However, with the right techniques and proper preparation, it can be a smooth and efficient process. Here are some tips to help you work with silicone RTV rubber in mold making:
  1. Measure and mix the silicone RTV rubber accurately: It's essential to measure and mix the silicone RTV rubber according to the manufacturer's instructions to ensure that it cures correctly and provides the desired results.

  2. Use a degassing chamber: To ensure that there are no bubbles in the silicone RTV rubber, a degassing chamber can be used. This will remove any trapped air that could create imperfections in the final mold.

  3. Use a release agent (optional): To ensure easy demolding, a release agent can be used. This will prevent the silicone from sticking to the mold and make it easier to remove the final product.

  4. Take temperature and humidity into account: Temperature and humidity can affect the curing process of silicone RTV rubber. It's essential to work in a controlled environment with a moderate temperature and humidity level to ensure the best results.

  5. Allow the silicone RTV rubber to cure completely: It's essential to allow the silicone RTV rubber to cure completely before removing it from the mold. This will ensure that the final product is accurate and detailed, and that the mold is durable and long-lasting.

By following these tips, you can work with silicone RTV rubber in mold making with confidence and achieve professional-grade results. Remember to always refer to the manufacturer's instructions and take safety precautions when working with silicone RTV rubber.
