What Is Over-molding Medical Devices With LSR ?
In modern medical manufacturing, product performance, patient safety, and device reliability are critical. One of the most advanced production techniques used to meet these requirements is over-molding medical devices with Liquid Silicone Rubber (LSR). LSR over-molding allows manufacturers to combine silicone with other materials such as plastics or metals to create medical components with enhanced functionality, improved comfort, and superior sealing performance. This technology is widely used in devices like respiratory masks, surgical instruments, wearable medical equipment, and diagnostic components. This article explores what LSR over-molding is, how the process works, its advantages, design considerations, and common medical applications. Understanding LSR Over-Molding in Medical Device Manufacturing LSR over-molding is a manufacturing process where liquid silicone rubber is molded over an
