Material Advantages of 17-4PH and Process Benefits of MIM (Metal Injection Molding)
Metal Injection Molding (MIM) technology offers significant advantages in the production of medical device components, especially for small, precise, and structurally complex metal parts that require high-volume manufacturing. This process involves mixing ultra-fine metal powders with binders and injecting them into molds. After debinding and sintering, the parts achieve high density (≥96% of theoretical density), high mechanical strength, and excellent dimensional accuracy—making MIM a highly efficient alternative to traditional processes such as CNC machining, stamping, or die casting. MIM is particularly well-suited for producing the following types of medical components: endoscopic structures, dental instruments, surgical clamps, joint components, injector gun parts, orthopedic locking screws, and micro-sized connector shafts. The process allows for one-step formation of intricate features such as internal cavities, threads, and barbs, significantly reducing the number of parts and assembly steps. This enhances the overall reliability and consistency of medical devices.
