MIM Intelligent Earphone Revolving Shaft Parts
MIM is widely used in the electronics industry, especially the development of cell phones, communications, fiber optic industry has led to the industrialization of the development of the MIM industry, the parts of this industry requires high precision, durability, commonly used products are: structural parts, connectors, shaped parts, cell phone card bracket slot and so on.
With the rapid development of the economy, mobile phones have higher and higher requirements for components. Powder metallurgy injection molding has been widely used, and mobile phone components use powder injection molding technology. Due to the market demand for lighter, thinner, and more beautiful mobile phones, the best technology is to reduce the size of mobile phones, and mobile phone companies are looking for using metal injection molding to make mobile phone components.
