The black masterbatch pipe technology is a systematic engineering integrating material science, mechanical engineering, and process control. The core lies in the high-quality preparation of black masterbatch and precise control of extrusion molding. By optimizing the raw material formula and strictly controlling the process parameters of each link, various black plastic pipes with uniform appearance, excellent performance, and long service life can be produced, meeting the application needs of multiple fields such as municipal administration, construction, and agriculture.
