From the point of view of the materials used in modern automobiles, in recent years the application of plastics in automobiles continues to increase, whether it is the external decorative parts, internal decorative parts, or functional and structural parts, everywhere you can see the shadow of the plastic production, and with the hardness of engineering plastics, strength, and tensile properties continue to improve, reshaping the automotive materials change has come, the automotive plastics process is accelerating. Especially for the rotomolded fuel tank, the use of plastic instead of steel rotomolding process to produce a variety of plastic fuel tanks, with light weight, non-explosive, not easy to leak, more secure and practical and other advantages, has developed into an ideal alternative to iron fuel tank.

Rotomolding fuel tank light weight, will not leak, good safety, easy to install, impact resistance, structural diversity, can be changed with the space allowed on the car, can be widely used in motor vehicles, motorcycle production lines, and so on. Nowadays, lightweight production is the trend, and increasing the use of plastic materials in automobiles has become the key to reduce the cost of the whole vehicle and its weight, and increase the payload of the car. Rotomolding fuel tank is fully in line with the automotive manufacturing industry this development trend, not only can fully meet the lightweight production requirements, and compared to the steel production once the paint is damaged or the first anticorrosion do not do a good job, it is easy to rust corrosion shortcomings, rotomolding fuel tank on acid, alkali, salt and other corrosion resistance is greater than the steel plate, the local damage will not corrode, in addition, the rotomolding fuel tank is easy to mold, so that the shape of the complex parts processing is very convenient! In addition, rotomolded fuel tanks are easy to mold, making the processing of complex shaped parts very convenient, which can save engineers the debugging time of abrasive tools and processes, and accelerate the process of commercialization of products, and to a certain extent, the use of automotive even has the advantage of cost reduction and efficiency.

In general, rotomolded fuel tanks to a certain extent to promote the automotive manufacturing industry to higher strength, better impact, ultra-high flow direction, but for the promotion of all-plastic cars, but also involves the aging, recycling and other issues, and to be further improved technology.
