Prepare AB liquid silicone rubber
Precise weighing: According to the proportion marked by the manufacturer (such as A weight ratio of 1:1), weigh A glue and B glue respectively into clean containers. Volume ratio estimation is strictly prohibited, as proportion errors may cause the silicone to fail to cure or become sticky after curing.
Stirring and mixing: Pour B glue into A glue and stir rapidly in one direction for 3 to 5 minutes to ensure that the two glues are fully integrated. During stirring, try to minimize air bubbles (stirring too slowly or unevenly will produce a large number of air bubbles).
Defoaming treatment (optional) : If the surface of the mold is required to be free of bubbles, the well-mixed silicone can be left to stand for 5 to 10 minutes, or defoaming can be done using a vacuum machine (for small batches of manual production, standing is sufficient).
Pouring/brush mold forming
Pouring method (suitable for simple prototypes) : Slowly pour the defoaming silicone into the sealed box/mold frame containing the prototype, and slowly inject from one side of the prototype to allow the silicone to naturally wrap around the prototype, avoiding direct pouring to generate bubbles. The silicone liquid level should be 1 to 2cm higher than the highest point of the prototype.
Brush mold method (suitable for complex and large prototypes) : First, dip a brush in silicone and evenly brush it on the surface of the prototype, especially on the detailed patterns, to ensure complete coverage of the silicone. After brushing the first layer, you can lay a layer of glass fiber cloth to enhance the toughness of the mold, then brush the second layer of silicone. Repeat this process 2 to 3 times, and finally fill the mold frame with silicone.
Curing and demolding
Let it stand at room temperature for curing. The curing time depends on the type of silicone, usually 4 to 12 hours (the higher the temperature, the faster the curing. Avoid high-temperature baking to prevent deformation of the silicone).
After curing, first remove the mold frame, then use a utility knife to cut the silicone along the parting line (if made by parting, simply separate it), take out the prototype, and obtain the silicone candle mold.
