The application of powder injection molding is more and more widely, mobile phone, it came into use of powder
injection molding technology. Due to market need lighter, thinner and more aesthetic phone, need to use the best
technology, to reduce the size of the mobile phone. Some mobile enterprise is seeking to make mobile phone assembly parts with metal injection molding.
The MIM application trend in the mobile phone industry
The president of a mobile phone brand said at a luncheon: "our first metal mobile phone is made of aluminum, we found that in order to meet the all the requirements, metal injection molding method is the best, in many cases it is the only choice". But the company did not use the metal injection molding parts as first material, because the mobile phone market life is pretty short and styles change quickly. While metal injection molding method has long production cycle and high production cost.
Mobile phone parts made with MIM tech.
Now there are several parts in mobile phone is made by MIM method. For example: the oscillator made with tungsten, use to balance weight, the hinge made with high strength steel, in the mobile phone the most important application of MIM is producing ramp, barrel and hinge. The company President said: "the advantages of MIM and its improvement will increase its application in the mobile phone manufacturing, mobile phone manufacturing industry lack of understanding of metal injection molding method has affected the application”.
Now, metal injection molding method is used to make some mobile phones with complicated structure and function, such as clamshell mobile phones. The company's president said: "from the manufacturing time and cost considerations, manufacturing common mobile phones should not use metal injection molding parts".
Metal injection molding(MIM), a new method of metal processing: combining organic binder and metal powder, using the traditional method same as plastic injection to form the parts. This method enables the production of very complex shaped parts similar to plastic products or die cast products, but with savings in resources and energy, which is very suitable for production in big quantity.
