Abstract
Un método de formar un forro moldeado por inyección en un cuerpo de válvula, que comprende las operaciones de montar el cuerpo de válvula con miembros de molde para definir una cavidad, e inyectar material de forro en la cavidad para formar el forro, caracterizado porque los miembros de molde están configurados de tal manera que la cavidad tiene una parte de forro que, cuando se llena con material de forro, define el forro deseado y un aparte de extensión continua con la parte de forro y que se extiende hacia fuera desde un borde de la parte de forro, inyectándose el material de forro en la cavidad a través de la parte de extensión.
