Compression Molded Rubber Seal Assembly for the Aerospace Industry
(click on thumbnail to enlarge)
This featured compression molded rubber seal was made using a grey rubber (BMS 1-57) compound and a corolon fabric. Because the fabric has a denser weave, it serves to increase durability.
The rubber and corolon were first hand formed in the mold, then placed in the press at 230 degrees Fahrenheit (F) for 10 to 15 minutes to assume the proper shape and continuity. After the newly formed seal was removed from the mold and cleaned, it was set to post cure at 300 degrees F.
During curing, the foam inserts and end plug (BMS 1-68) were formed by curing the liquid into pre-designed molds, and applying pressure and low-heat until complete. After curing, the seal’s holes and overall length were cut, and then it was assembled with the foam inserts and end plug, which serve to increase the product’s lifespan, fit, and performance.
The completed seal assembly was designed to be applied in several places on a commercial aircraft, where it was mounted to metal bulkheads, to enable the sealing of metal parts.
