Abstract

The invention discloses a manufacturing method for an automobile central control box. A low-pressure casting mode is adopted to manufacture a central control box body with a water channel; a water channel cover plate with a water flow groove is flushed in a CNC mode; and then the water channel cover plate is welded to the water channel of the central control box body through friction welding, andthe welded water channel cover plate and the central control box body form a sealed cavity. The central control box body with the water channel is manufactured in the low-pressure casting mode, the water channel cover plate with the water channel is manufactured in the CNC mode, and the central control box body and the water channel cover plate are welded in the friction welding mode, a brand-newprocess is formed. When the process is used for manufacturing the central control box, the mold opening cost is low, the mold opening period is short, the process is simplified, the produced automobile central control box is good in air impermeability and mechanical performance, the production cost is saved, and the formed central control box is high in integration level.
