How can I ensure that the SWORL reusable vacuum bag will conform tightly to the contours of the part being fabricated?
A. The SWORL silicone process is well suited to producing vacuum bags to the required part dimensions using one of three different methods. For thin-walled parts, the bag can be sprayed or brushed directly on the prepared mold surface. Because there is some shrinkage in the cured bag, it will conform tightly to part during fabrication. For thick-walled parts, manufacturers have a choice between building the bag over a sheet-waxed mold or over an existing part. To use sheet wax, begin by calculating the thickness of the final part. Then, build up the mold surface to the desired depth using sheet wax. Next, construct the SWORL silicone bag over the sheet wax, taking care to fill gaps and voids between wax sheets to prevent visible mark-off in the final bag. Allow the silicone to cure fully for two to seven days before demolding. Standard-size sheet wax is available in sheets measuring 8 in. x 12 in. or 12 in. x 24 in. and in a wide range of thicknesses. The wax sheet is supplied with an
