Abstract
EL MOLDEADO A PRESION UTILIZA UN MOLDE EN EL CUAL UNA BOQUILLA PARA ABRIR Y CERRAR EL PASO DE RESINA FUNDIDA SE ENCUENTRA EN UN MOLDE SUPERIOR O EN UN MOLDE INFERIOR, A ENTRE 10 Y 100 MM POR DEBAJO DE LA SUPERFICIE DE LA CAVIDAD DEL MOLDE. EL MOLDEADO SE EFECTUA A TRAVES DE LOS PASOS DE SUMINISTRAR RESINA TERMOPLASTICA EN ESTADO FUNDIDO ENTRE LOS MOLDES SUPERIOR E INFERIOR QUE TODAVIA NO HAN SIDO SITUADOS UNO CONTRA EL OTRO, Y AJUSTAR LOS MOLDES JUNTOS, MEDIANTE LO CUAL SE HACE POSIBLE OBTENER UN PRODUCTO MOLDEADO QUE TIENE UNA BUENA APARIENCIA INCLUSO CUANDO EL CICLO DE MOLDEADO ES CORTO.
