Molded Rubber Temperature Resistant Sealing Strip

In many automotive applications, there are frequently aggressive conditions and extremely high temperatures. Fire-wall applications are no different, and any rubber used to mold products for these applications has to be of the finest quality and specifically engineered and tolerate and endure highly elevated temperatures. Working in conjunction with one of the raw material supplier partners, Custom Rubber Corp. was able to engineer and develop a peroxide-cured EPDM material that met all the specifications.

In an effort to keep costs low, the manufacturing of this rubber part is broken down into two separate steps. First, the rubber part is molded in a separate process and then this finished product is adhered to the metal in a secondary operation. This process reduces the tolerance requirements on the metal insert, which reduces costs, because a raised cylinder can simply be tack welded to the metal plate instead of being machined on as a completely separate piece. Extensive testing was conducted to determine the best adhesive for this combination of rubber material and metal insert finish. Ultimately, a cyanoacrylate adhesive was chosen to bond the molded rubber to the metal insert.
