How to control the quality of resin trench cover is a very serious problem. Let's briefly understand how to do it.
1. Turn off the raw materials
The inspection of the steel materials used in the trench cover is the first step in the factory. It determines the formation and performance of the trench cover. Our company has strict quality inspection standards. Selecting high-quality raw materials can ensure the performance and quality of the field frequency. Strict raw materials The entry system must be all qualified for the used sand, stone and steel bars. Mix the concrete in strict accordance with the mixing ratio approved by the test engineer. According to the theoretical mix ratio, determine the operation mix ratio of each coil, and make corresponding measuring tools, accurate weighing, and its deviation meets the requirements of the specification. At the same time, the construction is listed, and the concrete operation mix ratio is marked for inspection and supervision.
2. Strictly control the production and design links
In accordance with the production standards for trench covers, there must be no errors. Continuously introduce domestic advanced production equipment and production technology, improve the quality of existing trench cover products, and strive to develop new products. And according to market needs, a detailed product development process has been formulated to ensure that new product development is completed in a relatively short period of time.
3. Do a good factory inspection of finished products. After our finished products are completed, there will be a professional quality inspector for quality inspection to check whether the product is standardized. If the product is not qualified, it must be restarted.

Our company is a manhole cover manufacturer such as resin manhole cover, polymer resin manhole cover, glass fiber reinforced plastic manhole cover. The following are the precautions for the selection of manhole cover molds: When choosing the manhole cover mold manufacturing materials, we should pay attention to the following: manhole cover molds with large parts output and stable shapes and sizes should be used. Made of high-performance materials, this type of mold material can also be subjected to low-vacuum surface strengthening treatment. The shape of the manhole cover mold is complex, the accuracy is high, the manufacturing cycle is long, and the processing cost of the mold is far more than the material cost of the mold. This mold should also be made of high-performance materials.
