With the upgrade of intelligent manufacturing,3D printing and high-end molds have significantly increased material performance requirements.PEEK (Polyether Ether Ketone) has become the core material for high-performance3D printing and precision molds due to its high-temperature resistance (printing temperature up to 380℃), and excellent mechanical properties (tensile modulus of 3.8GPa).
The Ministry of Industry and Information Technology’s “New Materials Industry Development Guide” clearly supportsPEEK in additive manufacturing and high-end mold applications, promoting the integrated development of materials–processes–applications.
This article combines the latest financial data to select six A-share companies that are simultaneously laying outPEEK 3D printing and high-end molds, with a rapid year-on-year growth in net profit attributable to the parent company in the mid-year report of 2025, for academic discussion reference.
