Comparison of Powder Metallurgy Metal Injection Molding with Stamping/CNC/Die Casting

The emergence of powder metallurgy technology has solved the problem that traditional molding technology can not solve. Compared with new materials and special materials, it can perform efficient molding and manufacturing, and provide accurate molding technology support for industrial development. Metal injection molding is the preferred molding technology for precision parts and complex parts in powder metallurgy technology. Compared with stamping, fine blanking, screw machining, CNC machining, EDM, die-casting, investment casting, powder metallurgy press molding and other technologies, zhongwei precision powder will introduce the comparison between powder metallurgy metal injection molding and stamping/CNC/die-casting to see which technology is better.

1. Die casting

Metal injection molding technology can handle alloys with higher temperature than casting. Because the metal injection molding alloy never melts, the polymer adhesive makes the powder have the required shape at a temperature similar to that of plastic injection molding, which can also achieve a long service life of precision parts.

2. CNC machining

The use of multi cavity MIM injection mold can provide high production efficiency, and reduce the cost of parts that are difficult to match through NC machining or EDM in MIM injection molding.

3. Stamping/fine stamping/screw processing

Complex three-dimensional geometry can not be produced by stamping, precision stamping or thread processing, but powder metallurgy metal injection molding technology can be easily achieved.

4. Investment casting

Compared with investment casting, metal injection molding has more advantages in cost, efficiency and quality in physical properties, surface smoothness, precision dimensions and batch production of complex parts.

The above is the comparison between powder metallurgy metal injection molding and stamping/CNC/die-casting, which enables everyone to have more knowledge and understanding of various molding processing technologies, and also enables everyone to have a new understanding of MIM injection molding. The sintered parts of metal injection molding are sintered to near density, and the metal injection molding technology allows more complex three-dimensional and geometric design.
