How to make silicone molds with liquid silicone?

To make a liquid silicone mold, you can follow the following steps:

1. Preparation: Ensure a clean working environment, prepare necessary materials and tools such as liquid silicone, mold prototypes, containers, mixing rods, anti adhesive agents, etc.

2. Prepare the mold prototype: Place the mold prototype in a fixed position, ensure its surface is smooth and clean, and apply a layer of anti adhesive to prevent silicone adhesion.

3. Mixing liquid silicone: According to the instructions for using liquid silicone, pour A and B liquids into a container in a certain proportion, and then stir thoroughly with a stirring rod until the two liquids completely blend.

4. Pour liquid silicone: Slowly and evenly pour the mixed liquid silicone into the mold prototype, taking care to avoid bubbles.

5. Vibration mold: Use a shaker or lightly tap around the mold to help the bubbles float and discharge.

6. Waiting for silicone gel to cure: Based on the curing time of the liquid silicone, wait for a certain amount of time until the silicone gel is completely cured.

7. Demolding: After the silicone is completely cured, carefully remove the mold prototype and gently bend the mold to separate it from the copied object.

8. Post treatment of the mold: Trim the edges of the mold and repair any possible defects, such as bubbles or unevenness.

The above are the general steps for making a liquid silicone mold, and the specific operation needs to be adjusted according to the actual situation and the instructions for using the liquid silicone.
