Aluminum Single Mold Frames - 1" x 1-7/8" x 2-7/8"

For deeper jewelry items or bulkier rings, these 1, inch thick aluminum mold frames offer the extra depth required. The 1-7/8 by 2-7/8 inch interior provides ample space for a thick rubber wall, which helps prevent mold distortion during wax injection. These frames are designed with smooth interior walls to make the removal of vulcanized rubber quick and easy. Their heavy-duty construction ensures they remain perfectly flat under the intense pressure of a vulcanizer.
