A seal of the type having a metal shell with a cylindrical flange and with an elastomeric layer bonded to each of the inside and outside diameter surfaces thereof is transfer molded by positioning the cylindrical flange of the shell in a seal-forming cavity of the transfer mold such that it is directly axially in-line with the sprue holes of the mold, whereby the flow of elastomer into the cavity is split by the cylindrical flange into two streams one adjacent the inside diameter and one adjacent the outside diameter of the cylindrical flange such that the fluid pressure against the cylindrical flange is equalized and distortion of the shell is substantially reduced or eliminated.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
