This higher Tg frees manufacturers to design parts that can withstand greater operating temperatures and high-temperature sterilization without warping. The materials also accept color more readily than standard PEEK formulations, supporting the creativity and branding goals of designers. In addition, compared to PEEK, the materials can be processed at lower temperatures to help manufacturers save energy during injection molding.  

Over 10 injection molding machines ranging from 50–550 tons Fully automated continuous fiber reinforced thermoplastic (CFRTP) injection-overmolding cell Mold Filling Simulation Simulates how melted plastic flows during the injection molding process to validate part design & material solution.

CLEVELAND – March 31, 2025 – Avient Corporation, an innovator of materials solutions, is pleased to share a successful collaboration with the Georgia Institute of Technology School of Industrial Design’s undergraduate industrial design students on a design studio project. Avient’s experts also delivered a guest lecture on design best practices and injection molding, offering valuable insights into the manufacturing process. Working with Georgia Tech's Industrial Design students has been an incredibly rewarding experience," said Jake Salter, Program Manager at Avient Design.
