Advantages and disadvantages of plastic fuel tanks
It is advantageous to use plastic to make fuel tanks with large processing and complex shapes. Other aspects of the advantages are: 1) two processing workload less; 2) because of other degrees of freedom, the tank can do a large number in the set space, 3) because the plastic is not corroded, don't worry like metal corrosion caused by leakage of oil tank that caused by pollution, 4) do not have to worry about the wheel thrown off stone broke the tank, 6) can eliminate noise. The downside is that gasoline may seep through the wall of the plastic tank. This point can be solved with an epoxy resin coating. Although the thermal deformation temperature of plastic is lower than that of metal, it can meet the requirement of automobile condition. The forming method of "plastic tank forming methods are: centrifugal molding method (rotational) and blowing method. In addition, there are casting, injection molding and vacuum forming. Which is the best choice for rotational molding
In addition, the plastic fuel tank is not prone to fire and explosion during friction and impact. In addition, the plastic tank cost is low, the equipment cost is lower than the metal oil tank. In terms of mould cost, a standard metal stamping die is 23~92.4 million yuan (yen) on average, while the plastic mould fee is only 1. 5, one, 15 million yuan (yen). Although the inserts for plastic fuel tanks are expensive, the total cost is cheaper than the metal tank.
Plastic has the advantages of small proportion, easy forming and non rusting. Using it to make an oil tank has a high degree of freedom of styling. It takes full advantage of the space inside the car and arranges it for the most safe part of the car crash.
