May 29,2023


Manhole covers, as a common road facility in our daily lives, are closely related to our daily lives. However, since many people cannot clearly control their quality when purchasing manhole covers, the following editor will teach you how to effectively control the quality of products?

1. Ensure the quality of raw materials

In the production of composite manhole covers, the first step is to ensure the quality of the raw materials, which directly determines the performance and quality of the composite manhole covers after molding. During the preliminary selection, the quality of the raw materials determines the overall quality of the manhole cover, and various details such as glass fiber content and resin quality will affect the quality of the product.

2. Do a good job in production process control

When producing composite manhole covers, national regulations and standards must be followed without any differences. At the same time, on the basis of existing technology, corresponding equipment and processes should be introduced to improve the production quality of cover plates, and new product research should be carried out continuously.

The above is about how to effectively control the quality of the composite manhole cover. After the product is produced, the product will also be pressure tested to ensure the overall quality of the composite manhole cover.
