Metal powder injection molding technology is a near-net forming technology for manufacturing high-quality precision parts, which has the advantages that conventional powder metallurgy, machining and precision casting methods cannot match:

 

1) Unrestricted structure: Similar to plastic injection molding, complex metal parts can be directly formed. 3D irregular surfaces can be realized by MIM process. Holes, grooves, recesses and sag can be designed, and threads, knurling, printing, etc. can be designed. Engraved trademarks, etc...

 

2) Easy to mass production: suitable for large-scale continuous production, batch product quality is stable and easy to control;

 

3) Reliable physical properties: the product texture is uniform and the density is good, and the density can reach 95%-99% of the theoretical density; the specific hardness requirement can be achieved by carburizing, quenching and tempering; the surface finish of the product can reach Ra1. 6, through the post-polishing process can achieve mirror effect; electrophoresis, electroplating (nickel plating, hard chrome, gold, silver, etc.), vacuum coating and other surface treatment process can achieve customer-specific color effects; 4) higher quality accuracy: powder metal injection Molding dimensional accuracy of up to +/- 5 ‰, some specific high-precision dimensions can be machined again;

 

5) Material selectivity: stainless steel, soft magnetic alloy, iron-nickel alloy material, tungsten alloy, hard alloy, tool steel and other special-purpose alloys can be realized;

 

6) High material utilization rate: the material utilization rate of gate runners can reach over 95%;

 

7) Material composition can be adjusted: special materials can be adjusted according to the performance requirements of customer parts;

 

8) Reduce the machining process: using the mold forming process, the product does not require or requires only a small amount of machining;

 

9) The cost reduction is obvious: powder metal injection molding can directly produce complex structural parts in batches, minimize the post-processing process, and the cost can be greatly reduced.
