Automotive urea tank - Advantages of the rotoplastic process

The rotoplastic process of automobile urea tank has the following advantages:

Light weight: Because the relative density of plastic is only about 1/7 of the metal, the weight can be reduced by about 1/3 to half compared with the metal fuel tank of the same volume.

Modeling at will: Because the process method of manufacturing plastic fuel tanks is different from that of metal fuel tanks, a single rotoplastic molding can be made into a complex shaped shaped fuel tank. Therefore, when the overall layout of the car has been determined, the shape of the fuel tank can be adapted to the space position, the remaining space of the chassis can be fully utilized, the fuel tank volume can be expanded, the fuel storage capacity can be improved, and the driving mileage of the car can be increased.

Will not explode: The rotoplastic process makes the urea tank more safe and reliable.

Uniform wall thickness: The wall thickness of the urea tank products is uniform, and there is no corner waste and no weld. Products with a large wall thickness range can be formed, such as polyethylene rotary forming parts, and the wall thickness range can be within 1~16mm.

No seams, high corner strength: The rotomizing process makes the urea tank compact, no seams, high corner strength, and improves the overall performance of the product.

Low dimensional accuracy: The dimensional accuracy of rotomized products is usually ±5%, which can lead to additional machining in some precision applications.

In summary, the rotoplastic process shows obvious advantages in the production of automobile urea tank, which not only reduces the weight, improves the freedom of modeling and safety, but also ensures the structural stability and certain dimensional accuracy of the product. These advantages make the rotoplastic process an ideal choice for the manufacture of automotive urea tanks.
