MIM Parts in Process
Metal injection molding(MIM) is metalworking technology, in MIM process, very fine metal powder will be mixed with binder material to create feedstock, then these feedstock will be formed and solidified by injection molding process. This MIM parts combine of metal powder and binder are named as– MIM green part.
After molding, chemical or thermal operations will be applied to remove binder materials. MIM parts after binder are called– MIM brown part.
At last, sintering process will densify metal powders by high temperature in furnaces. Then we will get —MIM finished part.
MIM parts can be treated like forging or casting metal parts, it can be welded, soldered, blued, hardened, tempered, polished, filed, and ground. Any operation you can perform on forging or casting parts, will perform same on MIM parts post-manufacturing.
MIM Parts Property
Although MIM materials powder is expensive than normal stock, and its special molds are horrendously expensive. We never ignore MIM parts advantages, it is high effective for high volume small size parts with complex geometries. Which is quite expensive to produce by alternative or classic metalworking methods.
1.Complex geometries: MIM parts can be any complex structure you need in product development or high quantity production.
2.High tolerance: MIM parts have high dimension accuracy for any special requirement. Our minimum tolerance will be ±0.5% on dimension and ±0.3% on target.
3.Excellent surface: MIM parts surface normally will achieve 1μm, so it can satisfy normal industry requirement without further secondary operations. For special MIM parts surface treatment, our multiple secondary operations will guarantee excellent chemical and physical properties for you.
4.High production quantity: With multi-cavity tooling usage, MIM parts offer high production rates of 10,000 pieces per day.
5.Various metal material: MIM parts have widely material range like: stainless steel, low alloy steel, iron-based, titanium,etc.
Now, MIM parts has wide application in various fields of industry: Automotive, Electronics, Medical, Industrial & Tools.
