SUS316 Stainless Steel Injection Molding Medical Surgical Knife Handle ISO9001

Passivated SUS316 Medical Stainless Steel Injection Molding Surgical Knife Handle

• Metal injection molding combines the precision of plastic molding with the strength of metal, creating complex parts efficiently, perfect for producing small, complex components efficiently.
• MIM(Metal Injection Molding) is an advanced manufacturing technique that combines plastic injection molding and metal properties. It is best suited to small detail parts, usually in the weight range of 1 to 100 grams of metal. The beauty of MIM manufacturing lies in its ability to easily generate intricate shapes with very tight measurements, which is why the MIM process is used in a wide range of applications, from medical devices to aerospace accessories.
