Composite well cover is one of the popular well cover products in recent years. Different from the traditional cast iron manhole cover, it adopts high-temperature forming process because it is made of composite materials. So what are the advantages of high temperature forming process of composite well cover?

Firstly, the composite well cover is a new type of environmental protection well cover. Composite well cover is a kind of fiber reinforced thermosetting composite material made of unsaturated polyester resin through molding process. The well cover produced by this method has the advantages of high polymerization degree, high density, good impact resistance and tensile strength, wear resistance, corrosion resistance, no rust and no pollution. The main reason why the high-temperature forming process is better than the casting process is that the internal high-temperature forming process only needs a small amount of electric energy during operation, showing its excellent environmental protection and energy-saving performance.

Casting technology not only has a great impact on the environment, but also consumes huge energy. Practice has proved that the high temperature forming process is more convenient and simple. As long as the temperature is set and reaches the set temperature, the raw material can be injected. However, the casting process is not as simple as described, because the temperature of molten iron and the structure of composite materials need to be controlled manually. Therefore, the requirements for operators are higher. Most manhole covers are made of composite materials. The circular design also helps to prevent irregular objects from falling, greatly improving safety.

It can also be seen from the well cover products that the products produced by high-temperature forming process are more beautiful, three-dimensional and exquisite, while the well cover produced by traditional casting process is rough.
