Description

Technical Field

[0001] This utility model relates to the technical field of extruder auxiliary devices, and in particular to a porous PVC-U communication pipe processing equipment. Background Technology

[0002] As is well known, with the rapid expansion and upgrading of communication networks, the demand for high-quality, high-performance communication conduits is increasing, especially for porous PVC-U (rigid polyvinyl chloride) communication conduits. Due to their excellent insulation, corrosion resistance, and ease of cable routing, they play a crucial role in the laying of underground communication lines. Traditional production methods for porous PVC-U communication conduits mostly rely on post-processing, i.e., first producing standard conduits and then forming holes through drilling or machining. This process is not only time-consuming and labor-intensive but also energy-intensive and inefficient. Furthermore, it can easily lead to damage to the conduit's structural strength and inconsistent hole diameters, affecting the installation and protection of communication cables.

[0003] Although some integrated molding equipment is available on the market, it generally suffers from problems such as high energy consumption, simple main mold design, inability to flexibly adjust hole shape and layout, and low yield, which limit the production capacity and quality optimization of porous PVC-U communication pipes, resulting in poor practicality.
