Silicone Molding Process of Sculpture

Get tools ready: rules, knife, hot melt glue, carbon board.   First, clean well the original mold, stick it with carbon board, get the carbon board around the mold to make a wall, and leave 2cm gap between them.   Secondly, due to the mold’s structure, pattern and application, choose silicone rubber with suitable hardness, add catalyst into it, evenly stir the mixture, then pour half of it into the model frame, and vacuum pumping, it’s better to choose -0.1mpa,which will avoid the bubbles in the silicone mold effectively, guarantee the silicone mold’s quality.   After vacuum pumping, pour all of the silicone mixture into the model frame, and shake well, and wait for it to solidify.   When it solidify utterly, pull down the cardboards, use scissors to trim around the silicone mold, and take the original mold out by cutting the silicone mold with blade.   Until now, the silicone molding is finished, and put the silicone rubber mold on production after 24 hours, which will keep the silicone mold in good shape and quality better.
