The Beginnings of Technology Import and Independent R&D

In its early years, Hanshen successfully developed a range of blown‑film extruders—including single‑layer, two‑layer composite, and three‑layer composite models—by adopting and adapting advanced foreign technologies, while leveraging years of independent R&D and innovation. Over time, the company has established a comprehensive technical system spanning design, manufacturing, installation, and maintenance.
