Plastic has the advantages of small proportion, easy forming, no rust, etc. The utility model can be used for the manufacture of the fuel tank, and the utility model has the advantages of large degree of freedom, and can make full use of the space inside the car and arrange the place where the car is crashed. In addition, the plastic fuel tank in the friction, impact is not easy to fire and explosion accidents.
In addition, mold costs, the cost of a plastic mold may be just a metal stamping die 1/10, easy for people to customize the design what they need. It is very advantageous to use plastic to make oil tank with large processing capacity and complicated shape.
Other advantages as well:
1) less than two processing workload;
2, due to the large degree of freedom, can be set in the space to make a larger tank,
3 because the plastic is not rust, do not have to worry about the metal oil tank as corrosion caused by leakage caused by pollution,
4) don’t worry about the broken oil tank,
6) noise can be eliminated.
The downside is that gasoline can seep through the plastic tank walls. This can be solved with epoxy resin coating. Although the thermal deformation temperature of the plastic is lower than that of the metal, it can still meet the requirements according to the condition of the vehicle.
Comparison of forming method: forming method of plastic fuel tank are: centrifugal molding and blow molding (rotational). Which is the best choice for rotational molding.
