How to heat treatment and gold plating of MIM powder injection molding process?
Metal powder injection molding (MetalPowderInjectionMolding, or MIM) is a modern plastic injection technology into the field of powder metallurgy, and formed a new powder metallurgy near net shaping technology. The basic process is: first of all, the solid powder and organic adhesive evenly mixed, granulated in the plasticized state (~ 150℃) under the injection molding machine into the mold cavity curing molding, and then with chemical or thermal decomposition to remove the adhesive from the forming blank, and then through sintering to densify, get the final product. Compared with the traditional process, it has the characteristics of high precision, uniform structure, excellent performance and low production cost. Its products are widely used in electronic information engineering, biomedical equipment, office equipment, automobiles, machinery, hardware, sports equipment, weapons, aviation and other industrial fields. Therefore, the international community generally thinks that the development of technology will lead to the revolution of parts forming technology, which is called "the welcome part of today's forming technology" and "the 21st century forming technology".
MIM powder injection molding process has unique advantages in manufacturing high quality precision parts. MIM injection molded parts can be heat treated, shaped, polished, electroplated, PVD, sprayed, laser, etched, just like traditional machined products. If we need to do further processing or processing of MIM injection molding parts, of course, there is no problem.
