The emergence of powder metallurgy technology solves the problems that cannot be solved by traditional molding processing technology. Compared with new materials and special materials, it can carry out effective and high-efficiency molding manufacturing, and provide precision molding technical support for industrial development. MIM injection molding is the preferred molding technology for precision parts and complex parts in the powder metallurgy process. Compared with stamping, fine blanking, screw machining, CNC machining, EDM, die-casting, investment casting, powder metallurgy compression molding and other technologies, it has more advantages. Next, Minxin Powder will introduce the comparison of each technology with MIM injection molding technology to see which technology is better.
Comparison of powder metallurgy MIM injection molding and various molding technologies
1: Die casting processing
MIM injection molding technology can handle higher temperature alloys than casting. Because MIM injection molding alloys never melt, the polymer binder makes the powder shape required at a temperature similar to plastic injection molding, which can also be achieved in a long time. Life span of precision parts,
2: CNC machining
The use of multi-cavity mold MIM injection molding molds can provide high production efficiency and reduce the cost of matching components in MIM injection molding through CNC machining or EDM.
3: Stamping/fine blanking/screw processing
Complicated 3D geometric shapes cannot be produced by stamping, fine blanking or screw processing, but powder metallurgy MIM injection molding technology can easily achieve it.
4: Investment casting
Compared with casting, MIM injection molding has physical properties, surface finish, and accurate dimensions. It can be manufactured in large quantities of complex parts. MIM injection molding has more cost advantages, efficiency advantages, and quality advantages than investment casting.
