Method of shaping drain covers

Now, manhole covers are widely used, and their usage advantages have been recognized by everyone. To better apply them in the future, let's take a look at the various shaping methods of manhole covers together.

Due to the wide application of manhole covers across various fields, their long service life demands high product performance, reducing investment costs. This is primarily achieved through vacuum degassing methods, which involve吸附 the product surface onto the mold and solidifying it, particularly suitable for the manhole cover extrusion process. The internal pressure method uses compressed air to pressurize cable trench covers. The products condense in the mold, causing the outer layer to adhere, rapidly solidify, and determine the shape. Once fully hardened, the products are uniformly pulled out using a draw knife.

The整形 mouth size, also known as the trimming method, directly extrudes the trench plate into shape without the need for a pulling device. A characteristic core mold straight section in the extrusion method is: 10-50m longer than the mold. The spiral thrust pushes the pipe out of the mold, directly into the condensation water tank, causing the outer surface of the pipe to solidify, while the inner surface is套 on the mandrel, preventing inward contraction. To ensure the stability of the trench cover during use, the installation should be carried out according to specifications to avoid unnecessary issues.

The above discusses the shaping methods for manhole covers. As their unique advantages become more and more widespread, we remind everyone to choose the appropriate construction method based on the actual situation during the construction process to achieve the best results.
