Why plastic materials win the favor of mobile phone manufacturers

First of all, easy processing can be regarded as the most dominant feature of plastics. The molding of plastics mainly adopts the processes of injection molding, pressing, etc., so it has great advantages in mass production, and it does not take as many as a metal casing to produce a process.

Secondly, the plastic material is lighter than metal, has sufficient strength and certain elasticity, and can be restored to its original state after being impacted. While the metal is hard, it is difficult to guarantee excellent toughness and can't compete with plastic. In addition, plastics have the advantage of being easy to color, and they can “put on” colorful coats. The shell of the iPhone 5C or Lumia series, which has both vivid colors and subtle sheen, is made of plastic. In addition, the insulation properties determine that the plastic material will not become a "blocker" for antennas and signals. Product signals made with this material are not easily shielded.

However, plastic mobile phones are not perfect. Compared with metal mobile phones, the frequency of mobile phone processors and graphics processors of this material will be lower.

In short, fish and bear's paw can not have both, mobile phone manufacturers should choose the phone body material should be based on the needs of consumers. But Xiao Bian believes that with the continuous development of science and technology, plastic materials may replace metal materials in the future.
