Metal Injection Molding (MIM)
What is powdered metal injection molding? Metal Injection Molding (MIM), sometimes called Powdered Injection Molding (PIM), is an advance metal forming technique that uses injection molding equipment for manufacturing both simple and complex metal parts to tight tolerances. Although MIM can be utilized across a wide range of components, the best applications are typically small in overall size and less …
Stainless steels in metal injection molding(MIM)
Stainless steels have played an important role in the development of MIM technology,and for this reason,many of the theoretical studies regarding the technological parameters were development with Stainless steels.The reason for this was the larger range of application for this family of materials,which was more than any other material in the period that MIM was being developed. All of the …
Environmental Properties,Biological Compatibility,Corrosion and Oxidation Properties
Erosion environment is complex, which is associated with multiple factors, including the test fluid and some details such as ventilation (gas), PH, concentration of halogen ions, contact with other materials, etc. Accordingly, any discussion of PIM materials environmental tolerance should include from sintering microstructure, heat treatment, test conditions to the detail such as the quantitative measurement of corrosion resistance.For this …
Metal injection molding (MIM)
Metal injection molding (MIM) is a metalworking process by which finely-powdered metal is mixed with a measured amount of binder material to comprise a ‘feedstock’ capable of being handled by plastic processing equipment through a process known as injection mold forming. The molding process allows complex parts to be shaped in a single operation and in high volume. End products …

Metal Injection Molding after processing
Function: improve the dimensional stability, elimination of internal stress Category:Heat treatment and Humidity treatment 1.Essence heat treatment:forcing frozen chain slack, solidifying the macromolecular chains are turning to random locations to eliminate internal stress, improve crystallinity, stable crystalline structure, improve modulus, lower elongation. 2.Humidity treatment:Will just release the product into the water, isolated from the air, preventing oxidation. Humidity conditions: 90~110℃ 4H. 3.Post-treatment: size requires more sophisticated parts, you need to make the necessary post-processing. This process is the same as the conventional procedures of heat treatment of metal products.

Powder metallurgy of common sense (1)
1.What is powder metallurgy? Powder metallurgy is a manufacturer of metal powders and metal powder (sometimes also add a small amount of non-metallic powder) as raw materials, mixing, shaping and sintering of manufacturing technology of materials or products. It consists of two parts, namely: (1) manufacture of metal powders (including alloy powders, hereafter referred to as “metallic powder”). (2)metal powder …
