Advantages of Powder Metallurgy MIM Parts Processing

There are many kinds of forming processing technology for metal parts processing, among which powder metallurgy mim parts processing is widely used in mobile phone parts. Powder metallurgy mim parts injection molding technology is a new powder metallurgy near net forming technology which combines modern plastic injection molding technology with traditional powder metallurgy technology. Mobile phone parts MIM powder metallurgy parts have high dimensional accuracy (± 0.1% ～ ± 0.5%) and good surface finish (roughness 1 ～ 5 μ m) And the output is very large. What are the advantages of MIM powder metallurgy processing? Let's talk about it in detail:

Powder metallurgy mim parts

1: High degree of design freedom. Compared with other metal forming methods, powder metallurgy injection molding of MIM parts can produce more complex parts. Basically, all structures that can be realized by injection molds can be used in MIM powder metallurgy injection molding.

2: Almost all metal materials can be used. Considering the economy, the main application materials of MIM powder metallurgy injection molding include iron base, nickel base, copper base, titanium base metals or alloys.

3: Because the sintering density is very close to the theoretical density, the physical and chemical properties of MIM powder metallurgy injection molding are also very excellent, such as mechanical strength, which greatly exceeds the traditional powder metallurgy.

4: The surface roughness (Ra) of MIM powder metallurgy injection molding sintered billet can reach 1 μ m. It can also obtain dazzling appearance effect through various surface treatment methods.

5: MIM powder metallurgy injection molding can generally achieve a tolerance accuracy of ± 0.5%. With other processing methods, MIM powder metallurgy injection molding can achieve higher dimensional accuracy.

6: MIM powder metallurgy injection molding can flexibly adjust and rapidly increase the output, from hundreds of pieces per day to hundreds of thousands of pieces per day.

7: The utilization rate of MIM powder metallurgy injection molding raw materials is close to 100%, which is a near net forming technology and can effectively avoid material waste.

From the above introduction, we can see that in terms of cost, material utilization rate, production cost and precision, mim powder metallurgy processing is superior, so many small precision mobile phone parts are more suitable for mim powder metallurgy processing.
