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. Without it, the company faced the prospect of having to use another production technique that would cost more and take longer. For this manufacturer, another appealing aspect of working with this material was Avient’s dedicated TPE production line in Spain, which is used solely to manufacture TPEs for overmolding applications.

This process has traditionally been conducted through trial and error with clinicians, using commercially available prostheses with access only to biased data and knowledge from past patient feedback. Humotech Caplex™ PRO-002 is a wearable device that is used to design and evaluate experimental prosthetic mechanical properties or to emulate and test-drive the mechanical properties of commercially-available prosthetic feet. Through the use of a software interface, a patient is given physical sensations of different prostheses while operators select various brands and models.
