One of the most common questions from medical OEMs seems simple: how thin can we go? But the answer is: it depends. One of the main factors is material choice. Can your design use a thermoplastic material that better suited for ultra-thin walls, like LCP? Or does your part functionality require other material characteristics, like the rigidity of PEEK, which is much more challenging for thin-wall molding? Or does your thin wall design require multiple materials for an overmolded component? While there may be many questions involved in figuring out how thin you can go, this article offers a few insights to keep in mind.
