AUTOMOBILE UREA TANK AND FORMING METHOD THEREOF

摘要

Disclosed are an automobile urea tank and a forming method thereof. The forming method comprises the following steps: firstly, producing an upper half casing and a lower half casing (2, 1) by means of injection moulding; assembling built-in components of the upper and lower half casings (2, 1) after the upper and lower half casings (2, 1) are formed; integrally welding the assembled upper and lower half casings (2, 1); and assembling components and parts on the surfaces of the upper and lower half casings (2, 1). The method improves the degree of freedom in the design of the built-in assemblies of a tank body, saves raw materials, has a simple structure and good firmness, improves production efficiency, and shortens the production period.
