High temperature molding process of composite manhole cover. The composite manhole cover is formed by high-temperature pressing of the mold. This method can improve production efficiency and does not need to hear the cumbersome processing technology for processing. Compared with the casting process of the traditional cast iron manhole cover, it is much simpler, but its manufacturing process. It is not inferior to the cast iron process, but more advanced. Next, let's take a look at the advantages of the high-temperature molding process of composite manhole covers.

1. The high-temperature molding process is more environmentally friendly and saves energy consumption. The high-temperature molding and injection molding process only consumes a small amount of electricity, but the casting process is not. When the furnace was fired with coal, it had a great impact on environmental protection. Now, after changing to an electric furnace, the power consumption is huge;

2. The high-temperature molding process is more convenient to operate. The high-temperature molding process is relatively simple in operation. As long as the set temperature is reached, the raw materials can be injected. With a little training, workers can operate, but the casting process is different. The same Products require experience in human operation, control the temperature of molten iron, configure other compounding materials, etc., and the performance of each batch and each ratio of the products produced is different;

3. The products produced by the high-temperature molding process are more beautiful and three-dimensional, while the roughness of the products produced by the casting process is higher.

The high-temperature molding process for composite manhole covers now seems to be a relatively scientific set of processing techniques, so it has certain advantages compared with traditional processing techniques, and the maturity of the process also has a certain impact on the production of manhole covers. The current technology can be said to do a good job to a certain extent.
