A special thickness Aluminum mold frame for jewelry mold making, is a single cavity mold frame measuring 1-7/8" x 2-7/8" x 7/8" thick for holding uncured Pre-Cut rubber and model when vulcanizing.
This frame is machined from a solid extruded aluminum bar, making it impossible to distort with excessive use, not like other frames that are cast or made from aluminum tubing which will distort or crack.
The cavity opening is made to accept all standard Pre-Cut mold rubber that is available in the market.
NOTE: To insure the proper flow and fill of rubber into the model, it is suggested that you pack one additional thickness of rubber in frame... this 7/8" mold frame, which will take Seven thicknesses of 1/8" rubber, should be packed with eight (One additional layer).
