Invotec helps medical manufacturer transition manual coiling process to a more repeatable, accurate, automated process. The Challenge A medical device manufacturer was struggling to produce consistent results in a highly complex, manual sub-assembly of their device. The process called for an operator to manually coil a delicate, .020” thick wire around the exterior of a mandrel. Doing so required operators to feed, wind, clamp, coil, and cut the material before transferring the device to a welding station—all of which was … Read More
Automated Assembly Preloads Needles for Ophthalmic Procedures
How Invotec helped one medical device manufacturer increase the efficiency and accuracy of a microscopic process with automated assembly. The Challenge An ophthalmic drug delivery company faced an inaccurate, manual process as well as increased demands for their ocular drug delivery systems. They needed an automated solution to replace their tabletop process, which relied heavily on operators and yielded only a 40% success rate. The challenge involved loading a needle hub assembly with a compact, cylindrical medicine. Due to the … Read More
Vision-Guided Laser Welding
Vision guidance is used in situations where the combination of tolerance stack-ups, beam diameter, and feature size would cause inconsistent welds. The Challenge With Precision Laser Welding When you manufacture medical devices, automotive sensors, and other intricate products, failure is not an option. With tight tolerances and complicated assembly processes, consistently laser welding complex components can be a difficult task to accomplish and maintain over a long period of time in a production environment. The focused spot diameter for laser … Read More
