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.

Design and materials are intrinsically connected in the best products. It follows, then, that starting the design process with an exploration into candidate materials could legitimately be referred to as intrinsic design. And isn’t this the promise of good design at its core?

The use of 2K (two-component) molding – in which the base resin is injected and allowed to set up for a short time, and then is overmolded by injecting the TPE – streamlines the manufacturing process. It required a high temperature and a strong injection pressure to bond to the acrylonitrile-butadienestyrene (ABS) substrate, which caused the resin to deform. High-end product line = competitive advantage: With Avient’s OnFlex-S TPE, developers successfully designed and produced a new, high-end product line that compares favorably with all-plastic sprayers in terms of appearance, performance and durability.
