Gasket manufacturing method

Abstract

A manufacturing method of a gasket that can stabilize the size and shape of the gasket without a mold. The manufacturing method of the gasket includes the steps of discharging liquid rubber onto a base member using a discharge device, and forming a rubber gasket on the base member by curing the discharged liquid rubber. The discharge device includes a valve body which opens and closes a flow channel through which the liquid rubber flows and a discharge port from which droplets of the liquid rubber are intermittently discharged as the valve body opens and closes a valve. The discharge device is a contactless-type discharge device used in a state in which the discharge port is not in contact with the base member.
