WIPO Patent Application WO/2024/018970
Kind Code:
A1
Abstract:
The present invention is a gasket molding method for molding a gasket on a workpiece, the method comprising, in the stated order: an application step (S1) for applying, to the inner side of a cavity of a molding die, an active energy ray curable liquid; a bonding step (S2) for bonding the molding die, to which the active energy ray curable liquid has been applied, and a workpiece; a precuring step (S3) for emitting active energy rays with a cumulative light amount achieving a reaction rate of 20%-85%; a mold releasing step (S4) for peeling off, from the molding die, the precured active energy ray curable liquid together with the workpiece; and a main curing step (S5) for emitting active energy rays with a cumulative light amount achieving a reaction rate of more than 85% and not more than 100%. The present invention thereby provides a gasket molding method that improves productivity even using a molding die.
