Due to the wide application of trench cover in various fields, it has a long service life, high requirements on product performance, and reduced investment costs. Trench cover extrusion process. The internal pressure method uses the cable trench cover to pressurize the compressed air. The product is condensed in the mold, so that the outer layer is adsorbed to the mold, and the shape is determined by rapid condensation and hardening. After all the products are hardened, they are pulled out evenly by the broach.
The size of the shaping mouth is also called the elimination method. The trench cover is directly ejected and formed, and no traction device is required. The characteristic straight part of the core mold in the ejection method is: 10-50m longer than the mold. The screw thrust pushes the tube out of the mold and directly into the condensate tank, so that the outer surface of the tube is condensed and hardened, while the inner surface is sleeved on the mandrel, which cannot be shrunk inward. In order to ensure the stability of the trench cover during use, the installation should be performed as required to avoid unnecessary problems.
The above is about the setting method of the trench cover. Due to its characteristics and advantages, the application rate is becoming more and more common. I remind you again that in the construction process, you must choose the correct construction method according to the actual situation in order to achieve good results. I hope the above content Help everyone.
