The Challenge Our customer needed a system that would assemble, test, and label their medical device. Using in-process checks, they wanted to verify that all components in the assembly complied with rigid quality standards; additionally recorded data from post-process testing operations was required on all of the devices. The Solution Invotec developed a system that employed lean cell technology in an assembly line approach— incorporating a manually indexing, pallet conveyor to transfer assembled components between operations. Machine vision systems were … Read More

The Challenge: Increase Production While Eliminating Error One manufacturer, known for their high-quality consumer products, faced forecasts that their current production capabilities could not handle. As a result, they needed to develop a system that could better facilitate part changeover and reduce cycle times—all while maintaining the integrity of their product. In addition, the company was moving production from Europe to the US. To keep costs low, the system had to accurately assemble, inspect, and test their product with minimum … Read More

laser welding on medical device assembly equipment

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

The Challenge One medical device manufacturer had a seal product that needed to be trimmed from its mold sprues. Unfortunately these seals did not hold their shape, were extremely pliable, and required tight tolerance cuts to make an acceptable assembly. The trimming process could not pull, stretch, or tear the material before cutting each gate free with no burrs. The Solution Invotec designed and built a system that uses a laser cutting method to accomplish this task. The system works … Read More
