　　There are several factors at play when protecting the pixels and internal components of your indoor and outdoor LED displays. LED module face mask are a prime example, and the best part is they do so much more than just protect. Read this article to learn more.If you want to make a big difference in the market, led display screen It is necessary to intensify the upgrading of products on the original basis in order to meet the consumption needs of consumers. https://www.atop-led.com/

　　LED display module mask (1)

　　As we learned that a lot goes into ensuring outdoor LED displays like billboards, business signage, and scoreboards are protected from the elements. After all, one bad North Texas storm or windy day could destroy picture quality and make it look dirty, worn, or stained. As a result, not only must the outside of these displays withstand Mother Nature, but all the intricate components inside must be protected, too. This is where LED module face mask help!

　　LED module face mask are an extra layer of protection for the “guts” of your outdoor LED display, your LED pixels, and internal components! They also significantly improve the overall image quality and create a more efficient display.

　　Let’s dive into this a little deeper, shall we?

　　LED display module mask (2)

　　LED Module Shaders/Masks/Louvers ！ The Perfect Complement to Your LED Display

　　It’s worth noting that an LED display’s pixels and internal components must be protected at all times. And there’s a lot that goes into that, especially for outdoor displays. For one, if you were to remove the face mask on your display and take a gander inside, you should see special silicone sealant surrounding each pixel. Surrounding them with sealant creates a water-tight seal that is extremely important for outdoor units. From there, the module’s face mask are added to help protect the pixels and components even more.

　　Led module face mask are black plastic screens that cover the face of the module. This dark separator of pixels provides for GREAT contrast that is unmatched in the industry! Sometimes they actually have little awnings that stick out from the surface of the shader to not only provide protection from the elements, but to provide a shaded area for the pixel to light up in´

　　So, led module face mask actually serve a dual purpose once they are installed:

　　Protection ！ We mentioned this already. Without these mask, all those intricate pixels or LED diodes could be damaged rather easily by rain, wind, snow, ice, moisture, dirt, grime, and more. Obviously, this would cost you hundreds if not thousands of dollars in repairs or replacement.

　　Contrast ！ When we say contrast, we are essentially talking about the measurement of light against dark. It¨s the distance between the whitest white and the blackest black in a video. And believe it or not, but the darker an LED screen can display, the better the image! This is because with a blacker background, the images will pop more vividly for the viewer¨s eye. Therefore, it¨s important to have nice, black plastic mask to provide a dark background for the pixels to light up against. The most effective module mask are designed to block sunlight and ＾shade￣ the LED pixels, thus improving the contrast of an LED display ！ especially during the daytime! If they aren¨t present, or if the shaders are cheap, old, and have faded from black to gray, the image contrast appears dimmer, and you end up with a less efficient display.

　　Cold heading and cold extrusion are basically deformation processes under the same conditions, but they are different in operation. Cold heading is a forging deformation of smaller workpieces and is often used in the fastener industry. Cold extrusion is an extrusion deformation of larger workpieces and has a wide range of uses.In addition to these aspects, non-standard fasteners price The performance in other aspects is also relatively good, which has attracted everyone’s attention and research. https://jieruifasteners.com/

　　1. What is cold extrusion

　　Cold extrusion is a processing method in which a metal blank is placed in a cold extrusion die cavity and, at room temperature, a punch fixed on the press is used to apply pressure to the blank to cause the metal blank to undergo plastic deformation to produce parts. Obviously, cold extrusion processing relies on the die to control the flow of metal and relies on the large-scale transfer of metal volume to form parts. In terms of extrusion equipment, my country has the ability to design and manufacture extrusion presses of various tonnages. In addition to using general mechanical presses, hydraulic presses, and cold extrusion presses, friction presses and high-speed and high-energy equipment have also been successfully used for cold extrusion production.

　　At present, cold extrusion technology has been widely used in industrial sectors such as fasteners, machinery, instruments, electrical appliances, light industry, aerospace, shipbuilding, and military industry, and has become one of the indispensable and important processing methods in metal plastic volume forming technology. With the advancement of science and technology and the continuous improvement of product technical requirements in the automobile, motorcycle, household appliances and other industries, cold extrusion production technology has gradually become the development direction of refined production of small and medium-sized forgings.

　　2. What is cold heading

　　Cold heading is one of the new processes of metal pressure processing with little or no cutting. It is a processing method that uses the plastic deformation of metal under the action of external force, and with the help of a mold, the metal volume is redistributed and transferred to form the required parts or blanks. The cold heading process is most suitable for the production of non standard fasteners such as bolts, screws, nuts, rivets, and pins. The commonly used equipment for cold heading is a dedicated cold heading machine. If the production volume is not too large, it can also be replaced by a crank press or a friction press.

　　Cold heading technology has high productivity, good product quality, and greatly reduces material consumption, reduces production costs, and improves working conditions. Therefore, it is more and more widely used in mechanical manufacturing, especially in the production of standard fasteners. Among them, the most representative products produced by multi-station cold heading machines are bolts, screws and nuts.

　　3. Are cold heading and cold extrusion the same thing?

　　Cold heading and cold extrusion are basically deformation processes under the same conditions, but they are different in operation. Cold heading is a forging deformation of smaller workpieces and is often used in the fastener industry. Cold extrusion, on the other hand, is an extrusion deformation of larger workpieces and is widely used; cold heading is equivalent to a branch of cold extrusion. Simply put, in the process of making bolts, hexagonal head forming is cold heading, and rod diameter reduction is cold extrusion (positive extrusion). Non-cut hexagonal flange bolts (multi-station forming) have both cold heading and cold extrusion. The front shaping of hexagonal nuts is only cold heading, and the hole extrusion in the back process is cold extrusion (positive and negative extrusion).
