福建CARD SLOT - MIM POWDER INJECTION MOLDING

Card slot is the most common component in mobile phones. With the popularity of mobile phones, it has brought spring to all configured industries, and MIM industry is one of them.

Many of the components in the mobile phone are powder injection molded, such as side keys, charging interfaces, vibrators, mobile phone headphone plug ornaments, camera brackets, etc., which are used in large quantities. Therefore, most of the MIM plants have grown up due to the rapid development of mobile phones, communications and optical fiber industries.

MIM powder injection molding process is suitable for mass production of small, precise and complex parts, such as common card slots in life, seemingly simple mobile phone parts, which require high density, high precision, smooth surface and convenience. At the beginning of design, customers' experience should be always considered - in order to improve the products that everyone just needs, many people's efforts should be combined behind. In addition, the mobile phone industry is updated very quickly, so it often happens that the Fuchi development team stays up all night on the production line to test and produce, in order to grab more orders in the shortest time. It may only take 3 months from the beginning to the end of the project, but the market output value and profit must be worth doing so by MIM enterprises.

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.
