Abstract

PURPOSE: To cast a compact and homogeneous base body of lead alloy having no cavity, by making a multistage pressurizing as the pressurizing method, when a pressure casting is made on the lead alloy by using a compressed inert gas.
CONSTITUTION: In the case of casting of base body, etc., of plate for lead storage battery, pressurizing is made relatively slow by setting the first pressure regulator 14 at an low pressure by adjusting timer 16, when molten lead 4 is injected into metallic mold 13. When the first pressurizing is completed after reaching the prescribed pressure, further pressurizing is made at a high pressure by adjusting the second pressure regulator 15 and the casting is completed. By this multistage pressurizing, a base body of plate for lead storage battery or electrode pole having no cavity can be casted with excellent workability.
