Computer, to the small can brush the drama, play games, to the large, through it, can allow us to connect with the world, as a common product in life, a good computer for consumers to consider many aspects, the first sight is its appearance, what kind of shell material to use is also where we need to consider.

Good computer shell materials help computers to dissipate heat, improve surface quality, increase service life, improve the use experience, good shell materials, is also a place for consumers to consider. Generally, plastic materials and metal materials are mainly used:

PART 1

Plastic material

01

PC (polycarbonate) material

Advantages: high strength, good heat resistance, and good heat dissipation, after surface treatment, the appearance feels like metal, but lighter than metal. Stable properties, weak acid and alkali resistance, corrosion resistance.

Disadvantages: poor flexibility, brittle texture.

02

ABS/PC alloy material

Advantages: It not only has the excellent heat resistance, weather resistance, dimensional stability and impact resistance of PC resin, but also has the excellent processing fluidity of ABS resin.

Disadvantages: poor thermal conductivity, heavy quality



PART 2



01

Magnesium aluminum alloy

Advantages: thermal conductivity, strength, pressure resistance are particularly outstanding. Moreover, the density of magnesium-aluminum alloy is low, and the feel is light and thin, which can meet the needs of 3C products with high integration, thinness, miniaturization, anti-fall and electromagnetic shielding. Silvery-white magnesium-aluminum alloy can be changed to other colors by surface treatment.

Disadvantages: The metal has strong thermal conductivity, and the surface is easy to get hot, which affects the sense of use.



02

Carbon fiber

Advantages: It has the elegant and strong characteristics of aluminum-magnesium alloy, and has the high plasticity of ABS engineering plastics. Similar in appearance to plastic, strength and thermal conductivity are better than ordinary ABS plastic, carbon fiber as a conductive material, can play a certain shielding role, heat dissipation effect is good.

Disadvantages: higher cost, more difficult to form than ABS, more difficult to color, simple shape of the casing and lack of change. If the ground is not good, there will be a slight leakage inductance.



In recent years, as the public pays more and more attention to environmental protection, many computer brands have begun to seek in-depth cooperation with professional recycled material companies and environmental protection enterprises, hoping to develop exclusive PCR materials to apply to their own products according to their own brand characteristics. In practice, this modified PCR material is not only more excellent, but also more environmentally friendly, in line with the general trend of green development.

According to relevant news, more and more computer brands will increase the proportion of recycled materials in computers:

Lenovo has promised that by 2025, 100% of its computer products will contain recycled plastic;

HP aims to achieve 75% resource reuse on HP products and packaging by 2030. Using renewable and recyclable materials in product design, such as using ocean-recycled plastic for computer parts, printing toner cartridges and ink cartridges;

Dell plans to make 100% of its packaging from recycled materials by 2030, and more than 50% of its products will be based on "recycled or recycled materials";

......

Lenovo ThinkPad neo 14, its shell is made of PCR PC-based renewable materials, mainly recycled sources

01

Since the recycled components of recycled materials such as discarded discs, films, and plastic buckets, its renewable material content is as high as 99%, flame retardants, and other additives account for 1%, which is at the forefront of heat resistance and durability.
