Liquid Silicone Rubber Mixing (Core: Accurate Ratio + Defoaming)

1. Weighing and Ratio: According to the instructions for the silicone and curing agent (e.g., 10:1), use an electronic scale to weigh the silicone and curing agent separately, then pour them into a clean container (it is recommended to mix enough silicone at once to avoid hardness differences from multiple batches).
2. Stir Thoroughly: Use a stirring rod to stir slowly in the same direction, avoiding vigorous stirring to prevent excessive bubbles (stir for about 3-5 minutes, ensuring no curing agent residue remains at the bottom of the container, otherwise, partial curing may occur).
3. Defoaming Treatment:
   • Simple Method: After stirring, let it sit for 5-10 minutes to allow surface bubbles to naturally rise and burst;
   • Professional Method: If a vacuum machine is available, place it in the vacuum machine for defoaming for 1-2 minutes (if no vacuum machine is available, this step can be skipped, but defoaming by letting it sit is necessary; otherwise, the mold may have bubble holes).

Silicone Pouring and Curing

• Slow Pouring: Slowly pour the defoamed silicone along the inner wall of the mold frame to avoid directly impacting the original mold (to prevent displacement or flattening of the texture), until the silicone completely covers the original mold and is 1-2cm higher than the highest point of the original mold (ensuring mold integrity).
• Secondary Defoaming: After pouring, gently tap the outer wall of the mold frame (3-5 times) to allow hidden bubbles inside the silicone to rise to the surface and burst (reducing mold defects).
• Curing by Standing: Place the mold in a cool, ventilated area (avoid direct sunlight or high temperatures, as this may affect silicone performance) and wait for curing according to the silicone instructions (condensation-type silicone typically fully cures in 24 hours; if the ambient temperature is low, it may take up to 36 hours).

Demolding and Mold Trimming

• Careful Demolding: After curing, first disassemble the mold frame, then slowly peel the silicone mold away from the original mold by hand (start from the edges, avoid pulling forcefully to prevent tearing). If the original mold has complex textures, gently twist the silicone mold to assist demolding.
• Mold Trimming: Use scissors or a utility knife to trim any burrs or bubble holes on the edges of the silicone mold (if there are small bubble holes, apply a small amount of silicone to patch and cure; this will not affect usability). Check if the internal texture of the mold is clear (clear texture indicates successful replication, and the mold can be used for subsequent pouring of resin/cement or other materials to make planters).
