North 1" Gaobeidian expands key technologies of CNC machine tools to high-end

On September 25, Liu Yuling, chief engineer of Beijing No.1 Machine Tool Plant, said that the plant invested nearly 300 million yuan in casting technology transformation last year, completed the expansion of Gaobeidian foundry company, and realized the casting of 150 tons of ductile iron in one piece. The manufacturing capability of machine tool products has become one of the milestones in the key technology of CNC machine tools in China.
In 2009, under the unfavorable situation of the financial crisis, “Beiyi” invested 300 million yuan to build a heavy-duty casting super-large casting production workshop of Beiyi Casting Base with a construction area of ​​12,000 square meters, forming the first machine tool in Beijing (high The “Beiyi Casting Base”, which is mainly owned by Casting Co., Ltd. and Beiyi Heavy Machinery Casting Co., Ltd., has an annual production capacity of 50,000 tons.

3020 SMD IR LED

3020 SMD IR LED supplier from China.

If you want some IR SMD LED, you must consider the 3020 IR LED, which is very common type of IR LED.

Same as the 3014 IR LED, the 3020 IR LED is popular because of the small size.

At the same power, the emission intensity of 850nm infrared will be a bit higher than the 940nm infrared. Astigmatism infrared is the biggest advantage of the SMD infrared, it is exquisite and strength, which is make it become a better choice for the Infrared induction, sweeper, launch and receive.

We produce and sell 3020 SMD IR LED, which is with the wavelength from 680nm-1550nm. In this category, we mainly introduce the two kinds of wavelengths: 3020 LED 940nm IR LED and 3020 LED 850nm IR LED. These two wavelengths are the most commonly used wavelengths in infrared monitoring. They all can be used to monitor products.

Then what is the difference between 940nm LED and 850nm LED ?
940nm infrared LEDs are totally invisible to the naked eye, which means you can't see whether the 940nm working or not. Unless you watch it through some device(like phone's camera), which will show some purple or white color light.
The 850nm infrared LEDs have a very slight reddish when it's working, which means you can see if the 850nm LED is working.
Under the same power, radiation intensity of 850nm will be higher than the 940nm. Of course, 940nm also has its own unique advantages. It is the naked eye that is indistinguishable from work or from work, therefore, its application has been widely used in many special markets in the modern era.
We supply the 3020 940nm SMD IR LED and 3020 850nm SMD IR LED products with difference power, such as: 0.1W 940nm, 0.2w 940nm, 0.3w 940nm, 0.4w 940nm, 0.1W 850nm, 0.2w 850nm, 0.3w 850nm, 0.4w 850nm and so on.
