With the development of communication technology, the popularity of smart phones has become more and more widespread, and the demand has greatly increased. Smartphones generally consist of a screen, a motherboard, a mobile phone holder and a battery, while the middle plate on the mobile phone holder is usually made of aluminum alloy material by die casting, because the aluminum alloy material flows very well through the mold cavity in the molten state. , Therefore, the die-cast aluminum alloy medium plate has a high yield rate.

The mobile phone middle plate is an important part of smart phone. The requirements for structure, strength and weight are relatively high, which determines the overall quality of mobile phone. Therefore, the quality requirements for the middle plate are higher than other accessories. Mobile phone middle plate is a kind of die cast alloy mobile phone inner plate, including side, middle plate body, etc.

Climb Aluminum has the ability to produce and process mobile phone midboards. This year (2022), we established a strategic partnership with Huawei, China’s largest mobile phone manufacturer, and began to produce the latest model of Huawei’s mobile phone middle plate.
