The efficiency of the design may be verified by recording the time it takes to make a complete color change while producing parts.

Injection overmolding with thermoplastic composite laminates combines the advantages of injection molding—the ability to create complex shapes and fast cycle times—with the lightweight strength and durability of continuous fiber reinforcement. The design team at Rome worked closely with the Avient advanced composites technical team and a local thermoformer, trialing various combinations of engineered resin and reinforcement, fiberglass content, and laminate configurations. © 2020, All Rights Reserved Avient Corporation, 33587 Walker Road, Avon Lake, Ohio USA 44012
