ABSTRACT:
A sprue former of the type used to produce a casting mold includes a generally hollow body or a body having hollow sections. The body includes an inlet forming member and at least one first interface member. The inlet forming member is configured to provide an inlet cavity in the casting mold to enable casting material to enter the casting mold. The first interface members are configured to couple to casting patterns. The casting patterns represent items to be cast. The body can also includes a reservoir forming member and at least one connecting member coupling the reservoir forming member to the inlet forming member.
