山东MOBILE PHONE HINGE

At present, all mobile phone brands are interested in folding screens, which also sets off a wave of technological competition. Folding screen mobile phone is a common part of the folding screen mobile phone and the previous flip phone hinge. At first, the cost of folding screen hinge design was high, such as using liquid metal and carbon fiber materials.

In the future, the price of terminal mobile phones will decrease. Brand manufacturers will adjust the design scheme of the existing hinges and use more MIM components to replace them, which may lead to a decrease in the value of the entire shaft and an increase in the use of MIM components.

In addition, as the future sales of folding screen mobile phones continue to increase, the space for the MIM parts and assembly costs in the hinge will also have some room for decline. The hinge has high production requirements, and the complex hinge even needs to be assembled with hundreds of parts. It is not only necessary to consider the customer experience, but also to do a durability experiment of up to 20000 times.

For MIM enterprises, there is a lot of business opportunities behind the new technology challenges. Many MIM technical engineers will help designers stay up all night for research and development, and they are constantly launching multiple multi generation folding screen mobile phones to win more market share.

In addition, as the future sales of folding screen mobile phones continue to increase, the space for MIM parts and assembly costs in the hinge will also have some room for decline. The hinge has high production requirements, and the complex hinge even needs to be assembled from hundreds of parts, which requires the customer's experience, and at the same time, 20000 durability tests will be conducted. The central core component of the folding screen rotating shaft needs to be light, flexible, thin Stable, etc. Therefore, MIM injection molding technology is very suitable to ensure progress, strength and stability.

Advantages of MIM in manufacturing mobile phone parts:

1. High efficiency, good at mass production of batch parts

MIM technology uses molds. Because of the high degree of production automation, its service life is equivalent to that of engineering plastic injection molding tools. Because of the use of metal dies, MIM is suitable for mass production of parts.

2. More refined parts

Alloying has good flexibility, wide application range of materials, the density of products reaches 95% - 99%, the internal organization is uniform, without internal stress and segregation, the surface finish is good, the precision is high, and the typical tolerance is ± 0.05mm.

3. Substantial energy and material conservation

MIM can use almost all metal materials. Considering the economy, the main application materials include iron based, nickel based, copper based, titanium based metals or alloys. Generally, the utilization rate of metal processing and molding is relatively low. For example, the utilization rate of raw materials for the metal shell of LeTV MAX mobile phone is less than 10%, and most of the aluminum alloys become debris. MIM can greatly improve the utilization rate of raw materials, which is 100% theoretically.

4. Structural parts with highly complex structure can be formed

Generally, the tolerance accuracy of ± 0.5% can be achieved with MIM, and higher dimensional accuracy can be achieved with other processing methods. Basically, all structures that can be realized by injection mold can be applied to MIM.

5. Environmental protection and safety

It is pollution-free and can realize continuous mass clean production. It is a near net forming technology and can effectively avoid material waste.

6. More material choices

Most metal materials can be used in MIM. In consideration of economy, the main application materials include iron base, nickel base, low alloy, copper base, high-speed steel, stainless steel, gram valve alloy, hard alloy and titanium base metal.
