The key advantage of rotational molding fuel tank

Why manufacture fuel tanks by rotomolding – isn’t steel cheaper?

There is a lot of advantages for rotational casting fuel tank. The key one is the flexibility when you need to maximized the available space. The rotational molding allow you to create the products to fit any area within vehicle, such as the space will include a tank. While Using metal, it could do the complex construction, but hard to do the same cost efficiency as rotomolding.

That's not to say rotomolding oil tank is suitable for every situation. But where a complexity occurs, rotational moulding give a cost effective solution. That's  Why rotational molding is widely applied in automotive industry, including a lot of trucks and vas. However the tanks are not for mass production vehicles, but more for industrial, low capacity vehicle, such as tractors, diggers and construction vehicles where maximum fuel volume is top priority.
