METHOD OF MANUFACTURE OF SEALING GASKETS Russian patent published in 2005 - IPC

FIELD: production of sealing gaskets made out of elastomers.

SUBSTANCE: the invention is dealt with the field of manufacture of sealing gaskets and may be used for production of sealing gaskets made out of elastomers. The method of manufacture of a sealing gasket made out of an elastomer with a filler with a density higher or lower, than the density of elastomer and at the filler non-uniform distribution along the sealing gasket cross-sections provides for performance of preparation of a mixture consisting of components of an elastomer and a filler, agitation of the mixture with its following casting in a sealing gasket mold having a working edge. In the case of manufacture of a sealing gasket with a filler of a higher density the mold is placed with its working edge in its lower part, and at manufacture of a sealing gasket with a filler of a lower density - in its upper part. At that before the casting process the mixture is exposed to aging within the given interval of time. The method ensures production of sealing gaskets with the given distribution along its cross-section of physical-mechanical properties depending on conditions of operation.

EFFECT: the invention ensures production of sealing gaskets with the given distribution along its cross-section of physical-mechanical properties depending on conditions of operation.
