The working principle of PVC double-wall corrugated pipe extrusion equipment is as follows. Firstly, the raw materials are fed into the extruder. The extruder then melts and homogenizes the materials under controlled temperature and pressure. The molten plastic is forced through a die that is specifically designed to form the characteristic double-wall corrugated structure. As the molten material exits the die, it begins to take on the desired shape. A vacuum is often applied to assist in the formation and stabilization of the corrugated walls. At the same time, cooling systems are employed to rapidly cool and solidify the extruded pipe. The continuous extrusion process allows for the production of long lengths of double-wall corrugated pipe. Various control mechanisms are in place to ensure precise dimensions, consistent quality, and smooth operation throughout the extrusion process.

PVC double-wall corrugated pipe module is designed with vacuum suction. This design feature plays a crucial role in the manufacturing process. By creating a vacuum environment within the module, it helps to firmly hold and shape the pipe material during production. The vacuum suction ensures better adhesion and molding of the pipe walls, resulting in a more precise and stable structure. It also enhances the quality and uniformity of the produced double-wall corrugated pipes. This vacuum design is an essential element that contributes to the efficiency and effectiveness of the double-wall corrugated pipe production, enabling the creation of high-quality pipes with desired characteristics.

The template undergoes nitriding treatment, which leads to high hardness and long service life. Nitriding treatment enhances the hardness of the template surface, making it more resistant to wear and abrasion. As a result, the template can maintain its integrity and functionality for an extended period, ensuring a long service life and reliable performance. This treatment greatly improves the durability and reliability of the template, allowing it to withstand the rigors of continuous use and ensuring its effectiveness over a long time frame.
