How to Use
1. Prepare the height increasing insole prototype and mold frame, clean and dry the prototype to remove all dust and oil stains to ensure mold precision.
2. Mix component A and B in a 1:1 weight ratio, stir thoroughly for 23 minutes until the mixture is uniform in color without stratification.
3. Perform vacuum defoaming on the mixed silicone for 25 minutes, adjust the time according to the actual silicone viscosity and weight.
4. Pour the defoamed silicone evenly into the mold frame, avoid air bubbles at the key thickness parts of the height increasing insole prototype.
5. Cure at room temperature for 45 hours or heat at 80120°C for 3060 minutes until the silicone is fully solidified.
6. Gently demold the cured mold and trim the excess silicone to get the finished height increasing insole mold.
FAQ
1. Can this silicone make molds for height increasing insoles with different height gradients?
Yes, it has excellent shape retention and no shrinkage during curing, suitable for making 15cm height gradient height increasing insole molds with precise thickness control.
2. How many times can the height increasing insole mold made of this silicone be reused?
Under proper storage and use conditions, the mold can be reused more than 500 times with stable performance.
3. Is vacuum defoaming a necessary step for making height increasing insole molds?
It is highly recommended, especially for molds with precise thickness requirements, to avoid air bubbles affecting the mold precision and the use effect of finished insoles.
4. Can the operating time and curing time be customized for largescale mass production?
Yes, we can adjust the product formula according to customer needs to shorten or extend the operating and curing time, matching the largescale production rhythm.
5. What are the key points for storing the unused liquid silicone rubber?
Seal and store in a dry indoor environment at room temperature, avoid sun exposure and rain, and the unopened product has a shelf life of 10 months.
