Today, the LED display industry has gradually entered the "cold winter". Often see the news of the LED display manufacturers closed down, but also saw the government's "light pollution" and "hard-working" 'red head files. More and more The local government has planned and managed the LED display screen. At the same time, the government did not dare to launch a grand event for the celebration activities. Whether it is the LED display of the engineering category or the LED display of the rental category, the manufacturers have been restricted and stimulated.
Regarding the LED display, I participated in every step of the shipment and knew that each process was important for the finished LED display. There are many manufacturers who are now taking the low-end route. A single squared display is just over a thousand different from other manufacturers. Of course, companies that specialize in reselling manufacturers' tails can still achieve ultra-low prices. But for the LED display properties, it is an electronic product. The biggest drawback of electronic products is instability, so even the "General Standard" also provides a range of display defect rates. The price given by a manufacturer for the LED display products it produces can at least illustrate two things. One is the grasp of the product, and the other is the reflection of the incoming product. To put it plainly, for the conventional products of P10 and P16, if its price is too low, this can directly reflect the quality of the cost, and there is no way to consider the process. And a mid-range manufacturer, it has a relatively high level of process control for these conventional P10 and P16, and the cost risk is also small. A high-end manufacturer, it will not spend a lot of energy to study conventional products, he will put more energy in other areas, but their cost risk is also small, the process is also high grasp. Cost risk plus process risk, to find a middle and high-end manufacturers more reassuring, but considering the purchase cost, the mid-end manufacturers have a very big advantage.
Doing LED display project is sometimes like a fight and it is very risky. If you just look at the price, do not consider the quality, the risk is too high, and sometimes it will outweigh the gains.
Investment in LED displays must also take into account risks. Finding a stable, rest assured manufacturer will allow you to do more with less. Now that the LED industry is surging, there are hidden crises everywhere. If you want to invest in the display, try to visit the factory and understand the operation of the LED manufacturers to ensure the stability of the entire cooperation.
Drag bits Include PDC Drag Bit and Step Drag Bit .
They are usually designed for use in soft formations such as sand, clay, or some soft rock. Their uses include drilling water wells, mining, geothermal, environmental and exploration drilling.
Whenever possible, they should be used to drill pilot holes, for they produce cuttings are easiest to log.
Normally drag bits are 3 wings, but we can make 4 or 5 wings following your drawings or samples.
Many special designs are available upon your request.
