Method of making a sealing arrangement

摘要

A method for manufacturing a sealing ring. A support ring is provided, and at least one pasty, magnetizable material is applied onto a side of said support ring. The material is then hardened. First and second elastomeric sealing elements are vulcanized to the support ring, such that the ring is covered by the elastomeric material of said first sealing element. The magnetizable material is then magnetized. The magnetizable material may be a paste with at least two homogeneously distributed magnetic materials. At least two magnetic materials may be applied in succession onto said support ring; in that method, the second magnetic material is not applied until after a step of hardening the first magnetic material. After said step of hardening, the support ring may be deformed and punched out.
