Modern industry is unimaginable without metalworking. Even the production of everyday objects requires some form of metal processing, and industries specialized in complex structures—such as automotive, firearms, or aerospace—could not exist without technologies capable of mechanically transforming metals. The MIM (Metal Injection Molding) process is relatively young, with just about three decades of history, so many people are unaware of it and assume that CNC technology represents the pinnacle of metalworking.
Characteristics of CNC Technology
CNC (Computer Numerical Control) allows manufacturing programs to be stored in memory and modified as needed. The CNC software controls the manufacturing process and any adjustments, either directly within the machine or on an external computer, determining the required speeds and movements. Before CNC machines, operators had to manually change tools and reposition workpieces. CNC technology automates tool changes and workpiece movements, significantly reducing setup times. Computer control also enables complex motions and processes that are impossible manually. Modern automated systems cover the entire workflow, and predictable processing times greatly simplify production planning. CNC is widely used and popular due to the high quality of the products it produces.
Advantages of MIM Technology
Metal Injection Molding surpasses CNC in many areas. One of its main advantages is speed: with MIM, up to 8 pieces of a given product can be produced in just 30 seconds, exceeding 20,000 pieces in 24-hour production rate unmatched by any other technology. Another key advantage is that MIM can produce very small components that other technologies cannot, and it does so at lower cost and with minimal material waste, which is also environmentally beneficial.
