What are the materials of mobile phones? What kind of materials do you have for your phone cases?

1. Polycarbonate.

Polycarbonate is an engineering plastic.

It is also the most widely used engineering plastic in mobile phones, with high strength, impact resistance, a wide range of operating temperatures, and free dyeing, making it a chameleon in the material.

2. Aluminum alloy.

Human beings have a good impression of metal since ancient times, in ancient times people painstakingly made iron utensils, modern metallurgical technology is developed, various alloys emerge in an endless stream, and aluminum alloy is the most widely used in the industry of a class of non-ferrous metals.

In the era of early keyboard feature phones, many will use aluminum alloy, but most of them are used in a small range of back covers, keys, etc., with the leadership of manufacturers, consumers' pursuit of design and quality is also rising, aluminum alloy aluminum alloy density is low, but the strength is relatively high, close to or more than high-quality steel, good plasticity, excellent thermal conductivity and corrosion resistance, began to become a new upstart in mobile phone design.

3. Stainless steel.

Stainless steel is hard, used as a mobile phone frame, which can make the whole machine stronger and have a good texture, but it is biased towards a tough style, and because of the physical characteristics of stainless steel, it is not like aluminum alloy can be anodized.

Out of a variety of colors, the general treatment process is drawing, polishing, diamond trimming, sandblasting, etc., to paint on stainless steel, it is very difficult, from the untimely Xiaomi Mi 4 Black Edition can be imagined.

4. Glass. Glass is a material that gives people the feeling of cold, clean and pure, and it is also a material that naturally makes people feel good, but compared with aluminum alloy and stainless steel, the plasticity of glass mobile phones is not so strong, and it cannot be used as a load-bearing structure of the fuselage, and can only be used as a decorative embellishment.

The screen is liquid crystal, made of glass and a liquid. Most of the keys are made of Shuo material, and the shell is made of Shuo material, aluminum alloy, and stainless steel. Precious metals are mainly on the surface of the circuit board, and the content is very small! The battery is made of lithium, and there is a liquid!

The materials of the mobile phone case are: plastic, PC material, leather, metal material, TPU.

1. Plastics. It mainly belongs to rubber, and the vulcanization molding is used in the finished product process. It is a piece of silica gel put into the mold, and then heated and pressurized to make the product, the silica gel is generally imported, and the bad silicone burrs will be particularly obvious, affecting the appearance.

2. PC material.

PC, scientific name polycarbonate, is a thermoplastic engineering plastic. The toughness and luster of the PC material are particularly good, the product can be made very thin, the thinnest iPhone case can be reached, and the color of the pure PC material is more.

3. Leather. The mobile phone cases are usually made of pig skin and cowhide. Generally, the outer layer of leather is used to venerate and the inner layer is made of PU material to reduce costs and achieve the visual effect of leather at the same time.

4. Metal material.

The texture of metal products is very good, the product grade is high, the disadvantage is that the installation is inconvenient, if it is a product installed with screws, it is necessary to operate carefully, because the metal material is generally made of aluminum alloy, and the screw hole is easy to slide open.

5. The hardness of TPU is generally harder than that of silicone, and the elasticity is strong, and the disadvantage is that it is easy to deform, yellow, and even foggy or sticky on the surface of the material if the material is not good.

In terms of protection, I personally think that liquid silicone phone cases are the best.

In fact, the advantages and disadvantages of mobile phone cases of various materials are also different, by the way, the advantages and disadvantages of several mobile phone cases that are more popular now.

Liquid silicone phone case.

Advantages: soft and skin-friendly, elastic, not easy to deform, good drop resistance, and relatively environmentally friendly and healthy.

Disadvantages: easy to get dust, poor heat dissipation, thick shell.

TPU phone case.

Advantages: relatively soft, with a certain elasticity, good impact resistance, cost-effective, with a variety of spray patterns.

Disadvantages: easy to yellow, poor heat dissipation.

PC phone case.

Advantages: light and thin, comfortable to the touch, bright colors, strong heat dissipation performance, scratch resistance.

Disadvantages: Slightly poor protection performance.

Glass phone case.

Advantages: Fashionable appearance, bright pattern and color, similar to the glass back cover of the mobile phone, wear-resistant and scratch-resistant.

Disadvantages: poor protection performance, easy to break, low slip resistance, and fingerprint collection.

Leather phone case.

Advantages: business style, looks very high-end, and feels good.

Disadvantages: not resistant to high temperatures.

The mobile phone case is currently available in "silicone, PC material". "Leather, hard plastic, metal, etc." The advantages of silicone are anti-drop and waterproof, and the toughness is good.

Easy to disassemble, good cushioning performance, easy to clean. The disadvantage is that it is not easy to dissipate heat, and the workmanship is poor. The PC material has strong impact and good toughness.

High transparency, non-toxic, easy processing and molding. The advantage of leather is that it has a variety of design styles and can be clamshelled in full packaging. The disadvantage is that it is easy to be hydrolyzed after contact with water.

The advantage of hard plastic is that it has a wide variety of varieties and patterns. The disadvantage is that the cushioning is very poor, and the top and bottom of the phone are not very protective. The advantage of metal is that the shell body is fine and textured.

The disadvantage is that it is expensive and freezes your hands in winter, which has a slight impact on the signal.

It is recommended to use silicone, which will feel better.

The original ** is generally expensive, and the style is single, so there are many imitation brands on the market. As far as mobile phone cases are concerned, there are all kinds of mobile phone protective cases on the market, which are dazzling and uneven in quality.

Silicone is better.

Silicone is a colorless and odorless material, soft and comfortable to the touch, and the silicone case has good elasticity, when the phone is accidentally dropped, it can be a good cushion. At the same time, the silicone phone case also has a large number of patterns, which can be selected according to your preference. However, the heat dissipation is a bit poor, which is not conducive to playing games for a long time.

Secondly, plastic mobile phone cases are also good, because plastic materials have excellent plasticity, wear resistance, and low cost, so most of the mobile phone cases on the market are made of plastic. Among them, acrylic and TPU materials have better drop-proof performance than other plastic materials, which can protect mobile phones well. However, due to the poor air permeability of plastic materials, it will affect the heat dissipation of the mobile phone.
