I understand 5G technology in one article, is it a revolution?

With the freezing of the fifth-generation communication technology (5G) standard, 5G is gradually becoming commercial. By 2019, there will be a large number of 5G mobile phones listed. In 2019, it can be said that the 5G mobile phone is the first year of true meaning, then 5G mobile phones are What are the advantages?

About 5G

Before talking about 5G mobile phones, let's talk about 5G. 5G network is the fifth generation mobile communication network. Its peak theoretical transmission speed can reach several tens of Gb per second, which is hundreds of times faster than the transmission speed of 4G network. High-definition movies can be downloaded in less than 1 second. In addition to high bandwidth, 5G networks have lower latency than 4G networks, and the Ping value of 5G networks can reach only a few milliseconds.

For mobile phones, the upgrade of 5G is actually the same as the transition from 2G to 3G and 3G to 4G. The most obvious user perception is the increase of network speed and the decrease of delay. However, the scope of application of 5G network has changed, and 5G is more than 5G. For mobile phones, but also for the IOT IoT, that is, the absolute main force of 5G networking in the future may no longer be just mobile phones, but also cars and a variety of IoT devices, and different IoT devices have different network requirements. Therefore, after the official commercial use of the 5G network, there may be two networks, one for the mobile phone and the other for the Internet of Things.

5G mobile phone

After knowing the definition of 5G, and then look at 5G mobile phones, what are the advantages of 5G mobile phones?

First of all, there is no doubt that the speed of the network is increased and the delay is reduced. The peak theoretical transmission speed of the 5G network can reach several tens of Gb per second, which is hundreds of times faster than the transmission speed of the 4G network. The entire ultra-high-definition movie can be in 1 second. The download is complete.

The current 4G network speed is already very fast, so is the speed of 5G network so necessary?

At present, even if the network speed is fast, but the telecom operators still charge according to the flow rate, few people will use the mobile network to download movies. Therefore, for mobile phones, the 5G experienced by users is far less shocking than the 3G/4G era. After all, mobile traffic is not cheap enough to download freely several G videos. Although 5G network is fast, it is for mobile phone users. It is said that the speed of the network is not a pain point. What operators really need to solve is the problem of traffic charges.

Great potential

In addition, the 5G mobile phone will become the backbone of the Internet of Things. It can control the Internet of Things devices through mobile phones, such as controlling the solar panels on the house with a mobile phone, controlling the air conditioner in the home, etc. The mobile phone is equivalent to the remote control.

Although the Internet of Things has been said for several years, it will only be erupted after 5G commercialization. The 5G network is actually prepared for the Internet of Things, including the unmanned driving of the Internet of Vehicles and telemedicine surgery. Example.

By the time the 5G mobile phone became popular in 2019, consumers might not feel the difference between 5G and 4G because of the lag in the corresponding industry chain. Now the price of mobile traffic has not reached the point where users can freely play movies.

But there is no doubt that the growth of a new thing requires a process, and in the next few years, 5G and 5G mobile phones will definitely shine.

Die Casting

The Die Castings that are created in this process can vary greatly in size and weight, ranging from a couple ounces to 100 pounds. One common application of die cast parts are housings - thin-walled enclosures, often requiring many ribs and bosses on the interior. Metal housings for a variety of appliances and equipment are often die cast. Several automobile components are also manufactured using die casting, including pistons, cylinder heads, and engine blocks. Other common die cast parts include propellers, gears, bushings, pumps, and Valves.

Die casting is a manufacturing process that can produce geometrically complex metal parts through the use of reusable molds, called dies. The die casting process involves the use of a furnace, metal, die casting machine, and die. The metal, typically a non-ferrous alloy such as aluminum or zinc, is melted in the furnace and then injected into the dies in the die casting machine. There are two main types of die casting machines - hot chamber machines (used for alloys with low melting temperatures, such as zinc) and cold chamber machines (used for alloys with high melting temperatures, such as aluminum). The differences between these machines will be detailed in the sections on equipment and tooling. However, in both machines, after the molten metal is injected into the dies, it rapidly cools and solidifies into the final part, called the casting. The steps in this process are described in greater detail in the next section.


Die cast parts can vary greatly in size and therefore require these measures to cover a very large range. As a result, die casting machines are designed to each accommodate a small range of this larger spectrum of values. Sample specifications for several different hot chamber and cold chamber die casting machines are given below.

The selection of a material for die casting is based upon several factors including the density, melting point, strength, corrosion resistance, and cost. The material may also affect the part design. For example, the use of zinc, which is a highly ductile metal, can allow for thinner walls and a better surface finish than many other alloys. The material not only determines the properties of the final casting, but also impacts the machine and tooling. Materials with low melting temperatures, such as zinc alloys, can be die cast in a hot chamber machine. However, materials with a higher melting temperature, such as aluminum and copper alloys, require the use of cold chamber machine. The melting temperature also affects the tooling, as a higher temperature will have a greater adverse effect on the life of the dies.
