FORMING APPARATUS HAVING CATALYST INTRODUCTION SIMULTANEOUS WITH SAND INJECTION

摘要

CATALYST INTRODUCTION SIMULTANEOUS WITH SAND INJECTION An apparatus and method for simultaneously injecting casting material (14) and a curing additive into a form (22). The apparatus (10) includes a container (12) of casting material (14) interconnected by a conduit (20) to a forming cavity (22). Casting material (14) is discharged into cavity (22) through conduit (20). An integrally formed chamber (36) is provided for simultaneously supplying additive to the discharging casing material (14). Casing material (14) Is forced into cavity (22) while simultaneously forcing the additive into the path of the discharging casting material (14). .
