Mobile phone protective cases can be divided into: silicone, leather case, crystal case, clear water case, mesh case, environmental protection PC case metal case, plastic and carbon fiber.

Silicone shell

Silicone case is the most well-known type of mobile phone case. Its soft texture and slightly slippery feel have been on the popular market for many years. The market share has always maintained a leading position from the development of crudely spread goods to well-crafted personality brands. Because of its excellent price-performance ratio, when the MP3 and iPod became popular, the silicone case became popular and was favored by many people. There are two types of silica gel shells, one is organic silica gel and the other is inorganic silica gel. Silicone cases for mobile phones on the market now basically belong to the former. Organic silicone has many advantages, such as high temperature resistance, good weather resistance (not afraid of UV or ozone decomposition), good insulation, and stable material (will not change with the animal body). In addition, people choose a silicone case because of its good feel: Some mobile phones with stiff keyboards will improve after putting on a silicone case. And it can absorb the impact of some bumps on the phone, thereby reducing the damage to the phone. In addition, the silicone shell has better water resistance, which has also become its biggest selling point. Although the silicone shell has many advantages, it is also cheap. However, there are still shortcomings. Due to the poor breathability, long-term wearing will cause the phone body to build up heat. In particular, some smart phones with relatively high heat generation are even less recommended for users. In addition, the silicone case itself is slightly sticky, and after a period of use, it will collect and adsorb a large amount of dust on the mobile phone. In the long run, it is not conducive to the beauty of the mobile phone and runs counter to the original intention of protecting the mobile phone. In addition to the above considerations, the purchase of mobile phone silicone case is also worth paying attention to one or two. There are a lot of silicone shells now, and they can be seen everywhere on the floor, in supermarkets and mobile phones. But it’s by no means that buying the right phone model is all good, the cheap silicone case is often of poor quality, either it can’t fit, or the position is asymmetric. Good quality is really good, and effective protection is king. At present, most of the regular silicone shells sell for less than a dozen yuan.

2.holster

Among all kinds of mobile phone protective cases, leather cases are also very popular. Compared with a single-style silicone case, business people who work hard in the workplace prefer to use generous and decent leather cases. Unlike young people who adore leisure, holding a single-color mobile phone is offensive to them. Similar to the silicone case, there are two types of mobile phone holsters. One is the waist-hanging holster that has been popular for many years, and the applicable type is more common. The other is a portable holster that can be put in a pocket. High-end smart models. Although the two may look different, the manufacturing process is similar. The advantages of the portable holster are chic and elegant, do not wear the phone, and have good heat dissipation, but it is not as waterproof as the silicone cover. At the same time, if the holster is too large, it is difficult to put it in the pants pocket, which is somewhat inconvenient to carry. The quality of the holster is also uneven. Although holsters can be found everywhere on the floor, but for a penny of goods, naturally more than a dozen yuan will not be made of genuine leather, mostly artificial leather or fake leather, which will soon crack and crack when used. The leather is durable and has a long service life. Of course, the price is also expensive, and the price generally ranges from tens to hundreds of yuan.

3. Crystal Shell

Silicone cases and leather cases have their own advantages and disadvantages. In order to achieve comprehensive protection, another mobile phone protective case has emerged at the historic moment. This is the crystal case that is popular with women. It is made of plexiglass, with a thick and sturdy appearance and a crystal clear shell. Not only can it effectively protect the mobile phone, but it does not greatly affect the appearance. It can be said to be as long as the silicone case and leather case. However, the purchase of crystal shells is also more tested. Although the cost of the crystal shell is not high and the process is relatively simple, some businesses can save labor and materials in order to earn higher profits. First of all, the appearance of the crystal shell depends to a large extent on the abrasive tool. The abrasive tool is good, and the quality of the crystal case is excellent. The size of the crystal case made by the irregular abrasive tool will vary, and some can not even fill the mobile phone. Secondly, the thickness of the crystal case is strict. If it is too thin or hard, it will break easily. If it is too thick, it will affect the operation. In addition, since it is called crystal, the shell of the crystal shell must be transparent, but some crystal shells are dull or even yellow, which is another problem of cutting corners. Of course, the crystal case also has disadvantages. Because it has certain hardness with the mobile phone, the two will inevitably produce friction, especially the corners of the mobile phone. Generally, these four parts of the mobile phone are the most severely worn. Shop carefully and don’t be afraid to compare goods. The crystal case is not expensive, at least tens of dollars, and the price is still very affordable.

4.Clear water shell

The clear water case is not a concept innovation. It is a combination of a crystal case and a silicone case. It belongs to a soft and hard mobile phone case made of transparent silicone. It is also named clear water because it is as transparent as a crystal case. The disadvantage of the silicone case is that the use time is long, the sleeve and the body are inevitably “paint like glue”, and sometimes it is necessary to let the mobile phone “fly out of the fan cage” to breathe; while the crystal case is brittle and easy to collapse, it may cause frequent replacement . The clear water shell is not easy to loose and is of the right size. It can be said that it has the advantages of both a silicone shell and a crystal shell. At the same time, for the beautiful appearance, the back of the clear water shell is usually printed with a delicate pattern, no longer like a silicone shell and a crystal The shell is dull in color. It is considered to be the perfect protection product. In the end, there is still the old saying that cheap is not good, and you should choose carefully.

5.TPU plastic

The second one is because TPU is also soft. It is a soft rubber product like silicone. Many people don’t know the difference between silicone and TPU. Even some Taobao sellers can’t figure it out. They say that the soft is silicone. . Let me explain to you. TPU belongs to the plastic type. The product is made by injection molding process. After melting a grain of plastic rice, it is injected into a plastic mold with a barrel to make a product.

Silicone is a rubber type, and the molding process is vulcanized. The silicone mold is opened up and down. Cut the piece of silicone material into pieces, put it in the mold, and apply heat and pressure to make the product.

Generally, plastic products have a plastic inlet. After the product is injection molded, it must be trimmed. If the trimming is not good, the appearance will be affected. Silicone does not have a rubber inlet, but there is a burr on the periphery to be repaired. If the mold is garbage, the burr will be more obvious, like a dog.

From the feel of the hand, the hardness of TPU is generally harder than that of silicone, and the elasticity of the pinch is strong, and the elasticity of silicone is slightly worse. TPU can be compared to the feel of muscle, and silicone can be compared to the feel of fat. Viewed from the outside, TPU can be made very transparent. Silicone can’t. The most transparent ones are very hazy like thick fog. It is precisely because of this transparent feeling of TPU that it is now more popular among users. In addition, there are still many high-end TPU products, which have strong selectivity and more pattern changes than silicone.

The disadvantage of TPU is that it is easy to deform and turn yellow. After three or four months, if you just buy a transparent white and other light-colored products, it will easily turn yellow. If the material is not good, it will even fog or stick to the surface. This problem is also caused by imported German Bayer materials, but it is relatively better.

6.Reticulated shell

Mobile phone case is a subtype of soft shell. It is named after the body is covered with mesh vents. The design is usually simple. After the rise of the Iphone, many users prefer mobile phone cases. For no other reason, the structure is sturdy and fast, and the mobile phone looks refreshing and simple at first glance. Of course, the disadvantages of the mesh shell are also obvious, that is, it cannot effectively prevent dust and water. After wearing it for a long time, there will be a lot of dirt deposited in the small holes, which is not conducive to the aesthetics of the mobile phone, so pay attention to cleaning it in a timely manner. At present, a leather mesh shell is emerging on the market, that is, the mesh shell body is covered by a leather jacket, and only the mesh design of the button part is maintained. This strengthens the waterproof effect of the mesh case, and has a more unique appearance, while still retaining some of the heat dissipation function. Overall, the usability has improved comprehensively.

Epoch-making new development-3D mobile phone case

Compared with the case sold in the modern market, the 3D mobile phone case has a further leap in picture quality and quality. Compared with the flat mobile phone case sold in the market, the 3D mobile phone case has a new 3D picture quality experience, which can better reflect the pursuit of personality and beauty of modern young people, and shape a perfect imaging as a whole, and experience the perfect exchange of technology and fashion . In terms of quality, it will not be used for a long time like a silicone case, which will inevitably cause the cover and the body to be “paint like glue”. Sometimes, it is even necessary to let the mobile phone “fly out of the cage”. It is brittle and easy to collapse, which may cause frequent replacement. However, the 3D case uses Bayer pc materials imported from Germany, which is not easy to loose and is of the right size. It can be said that it has the advantages of both a silicone case and a crystal case. At the same time, it also has perfect 3D images, allowing the entire phone The shell looks more perfect and stylish, and greatly exceeds the effect of the clear water shell, becoming the most perfect protective shell product on the market today!

3D mobile phone case purchase note

Although the 3D mobile phone case has a three-dimensional picture quality, you need to pay attention to whether it is marked as naked eye 3D when buying. It is not specified that the product is a naked eye 3D case. When buying, you need to pay attention to the actual 3D effect. Yu Wu. At the same time, when buying online, because the effect of the 3D chassis cannot be visually represented on the computer plane, you need to identify the brand of the chassis when purchasing.

There are practical and aesthetic types

The practical type is easy to use and can be worn around the neck. The shape is simple but easy to pick up; the beautiful type is interesting, such as: “piano type” and “lollipop type”. It is beautifully made and has strong simulation. , But the price is generally more expensive, slightly larger, and less practical
