Powder injection moulding (PIM) has been used more and more widely, especially in mobile phones. Because the market needs lighter, thinner and more aesthetic mobile phones, and needs to adopt good technology to reduce the size of mobile phones, a mobile phone company is seeking to use metal injection moulding method to manufacture mobile phone assembly parts.

At a luncheon, the president of a mobile phone brand said, "Our first metal mobile phone was made of aluminium. We found that in order to meet all the requirements, metal injection moulding is a good method and in many cases the only choice." But the company does not use metal injection moulding parts as the first material, because the market life of mobile phones is very short, the style changes quickly, and the production cycle of metal injection moulding method is long, and the production cost is high.

Nowadays, several parts of mobile phones are manufactured by metal injection moulding (MIM). For example, the oscillator made of tungsten is used to balance the weight and the hinge made of high strength steel. The important application of MIM in mobile phones is to make slides, barrels and hinges. "The advantages of metal injection moulding and the improvement of metal injection moulding technology will increase its application in mobile phone manufacturing. The lack of understanding of metal injection moulding in mobile phone manufacturing industry has affected its application," said the company's president.

Nowadays, metal injection moulding (MIM) is only used to make some mobile phones with complex structures and functions, such as mobile phones with flips. The company's President said: "Considering the manufacturing time and cost, it is not appropriate to use metal injection moulding parts to manufacture ordinary mobile phones."
