  LED display solutions vary with Installation Methods 1. On poles or on top of roof The outdoor led display screen is installed on the pole or the roof to broadcast advertisements, Chipshow C-Fit P2 / P3 / P4 / P5 / P6 / P8 / P10 led display s the ideal choice,that 960 * 960mm die cast aluminum box has low weight, high precision and high flatness of the whole screen. Then, confirm the appropriate pitch according to the screen area and the best viewing distance. 2. Wall mounted installation The LED display screen is attached to the outdoor wall to play advertisements. With our C-Fit-Easy P5 / P6.67/P8/P10, you can make only 300mm thick the steel structure for heat dissipation owing to its front and rear dual maintenance modules, so light weight and beautiful to hang on the wall. Meanwhile,we can use c-smart P4 / P5 / P6.67 / P10 which is more convenient solution for the wall mounted display within 20 square meters. The module frame can be directly fixed on the ...

  How to make a curved outdoor advertising led screen Now outdoor digital advertising led screen is popular,sometimes customer ask me how can I make a outdoor curved led screen . Before giving out our solution, especially before production, we would like to collect the following information: 1:Is it convex or concave curve? 2:Is it ellipse, semicircle, or 360 degree LED display? 3:What is the total length and height of the curved LED display? 4:What is the radian and radius? Please provide the accurate architectural drawing for our engineer to calculate correctly. The distance from the LED display to the ground and the normal viewing distance? This helps to choose the product model based on the pixel pitch. In addition, to install a curved LED display, the support structure needs to be customized according to the drawing of the LED display. Below is our outdoor curved led screen new case for reference: 1. We should know the screen Radius 2. Then we using CAD...

  Learn More Ab out LEDs 1. What is an LED? A light emitting diode (LED) is a tiny, electronic semiconductor that converts electric energy into visible light. The chemical compound used within an LED determines its color, brightness and power efficiency. Unlike incandescent lamps, LEDs have no filaments that can burn out or fail. Surface Mount LEDs Surface Mount Devices, or SMD for short, refers to the LED lead frame mounting method. LEDs are mounted to the surface of the circuit board. The SMD contains red, green and blue die. Through-Hole LEDs Through-hole LEDs are mounted with leads protruding through the circuit board and appear to stand taller. Each LED is a single-color die of either red, green or blue. LEDs come in two different forms. Manufacturers use several types of LEDs to construct digital displays. The two most common are Through-Hole LEDs and Surface Mount Device (SMD) LEDs, also known as Surface Mount Technology (SMT). Each type has its re...

  Casting is the process of melting the metal into a required liquid and pouring it into the mold. After cooling, solidifying and cleaning, a casting (part or blank) with a predetermined shape, size and properties can be obtained It is the basic technology of modern machinery manufacturing industry. The cost of casting blank is low, especially for the parts with complex shape, especially with a complex cavity, it can show its economy, at the same time, its adaptability is wide, and has better comprehensive mechanical properties. However, there are more materials (such as metal, wood, fuel, molding materials) and equipment (such as metallurgical furnace, sand mixer,   grinding ball molding machine , core making machine, sand falling machine, shot blasting machine, etc.) needed for casting production And will produce dust, harmful gases and noise and pollution of the environment. Casting is the process of melting the metal into a required liquid and pouring it into the mold. Aft...

  1. Tempering for grinding casting ball : The microstructure obtained by high-temperature tempering is tempered sorbite. The main purpose of tempering is to eliminate quenching stress and get the required structure. According to the different tempering temperature, tempering can be divided into a low temperature, medium temperature, and high temperature. Tempered Martensite, troostite, and sorbite were obtained. The quenching and tempering heat treatment is called quenching and tempering heat treatment, which aims to obtain the strength, hardness, and plasticity, toughness is better comprehensive mechanical properties. Therefore, widely used in automobiles, tractors, machine tools and other important structural parts, such as connecting rods, bolts, gears and shafts. Hardness after tempering is generally HB200-330. 2. Annealing The main aim of annealing is to make the internal structure of the metal reach or close to the equilibrium state and to prepare for the subsequent processi...

  3.The graded austenitizing isothermal quenching process 3.1 Effect of grade austenitizing austempering on mechanical properties of  Grinding Ball After the ball was austenitized at 980 °C for 150 min + 920 °C for 30 Min, and then put into a salt bath furnace at 260 °C for 30 min and 50 Min, the hardness and impact toughness of the ball were tested as shown in Table 3. The hardness and impact toughness of the grinding ball after 30 Min and 50 min austenitizing austempering are equivalent. The surface hardness is about 59HRC, the center hardness is about 54.5 HRC, and the impact toughness is 7.1ー7.4 J / cm2. The surface hardness of the grinding ball is similar to that of the quenched and tempered state, the impact toughness is greatly improved, and the comprehensive properties are slightly improved. 3.2 Effect of graded austenitizing austempering on microstructure The microstructure of the grinding ball after 50 Min austenitizing isothermal quenching is shown in Fig. 6. There ...
